wireless powered recumbent. Chitty Chitty Bang Bang model

[andrewCR]

looking to crowd source and open source the ultimate delta recumbent

Criteria:

Must be fun, sexy, "WOW" factor, comfortable, eco friendly, reliable, simple, mas production, cost effective, easy to ride, on and off road, pedal assist, innovative... and a little crazy..... a modern day Chitty Chitty Bang Bang of electric recumbents.... drive .. float.. fly.. made of wood and bamboo...

want to incorporate wireless electricity ... http://www.ted.com/talks/view/lang/en//id/619

fist stage is the open air model and then make a version with a more utilitarian focus with ability to carry stuff and be protected from the weather as well as road worthy and legal.

must have a focus on helping people like the DIY bike shops that are springing up that are re-cycle bikes and have peoples lives enhanced in the process. A open source/ crowd sourced franchise of sorts...

inspiration

feels like a kids Big Wheel and a glider plane .. video game...

would be kewl if u can build it out of bamboo and wood and it was amfibious.. flying would be neat too... ( i did say crazzy)

http://endless-sphere.com/forums/viewtopic.php?f=1&t=10697

Im an innovator, visionary and business man. here is my latest venture with Google. http://www.vizzeco.com

I live in Stouffville Ontario, Canada and 6 moths in Costa Rica http://www.lsrm.com . Would u be interested or know who would be best to work with to help me build a custom recumbent?

I want it for off and on road and mountainous areas...

Here is what im looking to build:

front half of a funcycle or similar lean steer set up with suspension. http://youtu.be/3b4YsZ9-dWU

for front suspension im thinking of using the rear half of a kids 20" wheel frame (mono arm) that has suspension and mount it on top of the existing funcycle frame with two supports that are welded from the seat post to the front arms (forks) of the funcycle.

Nuvinci VST in a E Bike http://www.youtube.com/watch?v=UVoTj3tfmWA

electric assist 1000 watt in line external motor that makes use of the Nuvinci.... or a geared electric hub that would do the same and u can access the gears even if u are not using the electric motor for when u are peddling .. if there is such a thing.

the ideal soloution would be a electric automatic geared hub with the crank for the peddles mounted on the hub like this.. http://www.profit2000.ru/variator/ with coster brakes... but... that would mean i could not have front suspension.. so probably best if i stick with the chain and sprocket set up... and i beleive the lean sterr would require the front drive wheel to be to close to the driver....

this is what i want for the back half http://youtu.be/fjbIAVladHs

I also want the back end to Incorporate suspension as well.... looking for ideas in how to incorporate suspension into the jet trike back end as well as dampeners (shocks) to get rid of bump steer and speed woble at high speed as well as keeping u up rigt when stationary.

rear independent disc brakes for better stopping power and the ability to do break steer. costa rica has some wicked mountains and mud.. rough roads.

I also want to put the final product into production for sale to the market.

some ideas are... a bizz model that combines West Jet and a Credit union and a co op or buying group combined.

the employees and the customers have majority stake in the company.

i want to make the recumbent available as a service... something like $4 a day all inclusive with no up front cost.. or a per km or mix of those.

clean efficient diesel motor is also something im gonna try... im an advisor to the board of http://www.dynamicfuel.com/ and they have drastically reduced emissions and increased fuel efficiency as well as extended the life of the engine using hydrogen see CARB certification here http://www.dynamicfuel.com/announcement/pdf/CEE%20CARB%20Summary-feb2012.pdf ..... it replaces the catlytic converter (or equivalent) but it increases fuel economey and power and less harmfull than the catlytic converter when it has to disposed of... Dynamic Fuels solution burns the pollution.. it does not capture and store it. look at the growth in the market of the VW TDI Jetta.. I like the idea that u can be clean and more efficient and compare this head on with electric.. Bio fuels are also kewl... cradle to cradle.. it will be interesting to see which one is the better answer.. my gut says the clean diesel is the interim stop gap solution...

i will use http://www.kickstarter.com/ to raise money for the stage after the prototype is complete.

Sorry to burst your bubble, but true "wireless power" is a pipe dream at this power level.

Transmitting useful amount of power via EM over more than tiny distances is so difficult as to be considered impossible for a commercial product at today's technology level. There are a host of good reasons for this, but the laws of physics play a good part in making this a very difficult thing to do at anything above extremely low power levels. As the power required to run portable devices (like, maybe, 'phones) reduces then it *may* be possible to transmit the very small amounts of power they need via EM, but there isn't a way to reduce the power need of something like an ebike.

 

[Drunkskunk]

would be kewl if u can build it out of bamboo and wood and it was amfibious.. flying would be neat too...

You just sort of took a broad wack at the whole idea of ebikes and hoped you hit something that might work, right?

Crowd source for profit is opportunistic bottom feeding.

Come up with an actual idea, an actual plan, and people here might be willing to help. Bring this kind of neurotic pipe dreaming, and most here are smart enough to realize they are just being exploited for your profit.

 

[ohzee]

lol

 

[dogman dan]

Dream on bro, but you'll have to figure out how on your own. The bar is too high for me. One step at a time gets the journey going on it's way. Mabye just start with learning to make bamboo frames for regular hubmotor kits? Or regular chain drive kits.

OUCH!

I do admit that my posting title was intended to get noticed.. there is a madness to my method. ;-0

im dyslexic and DDA and i tend to do things backassward.

can u share with me what u have crowd sourced or have been part of a good crowd source experience? What does crowd sourcing mean to u? So crowd sourcing that includes everyone getting compensated .. reciprocity model... not something u like? do u live a life where ur work is ur passion and sharing this with others enhances their lives and money comes easily? I do.

soo.. do u like star trek?

a lot of really kewl things came from the futuristic dreaming of Roddenberry.. cell phone... Startec Flip phone.. flat screen monitors.. computers u talk to.. etc.. etc...

do u believe that NASA actually went to the moon?.. or was it all entertainment?

u have assumed my intentions incorrectly.. i apologize if i come across as u say...

I looked at ur postings.. nice ride... u obviously know ur stuff.. im just new to this..

I guess not everyone has a sense of ha ha.. or likes Chitty Chitty Bang Bang.. oh well..

dont take life to seriously.. no ones getting out alive anyway! Bugs Bunny quote.

My company was born from a crowd sourcing kind of event... “The Limits of Sponge Bob Square Pants” by Robert Cringely. Roberts work has appeared in The New York Times, Newsweek, Forbes, Upside, Success, Worth, author of the best-selling book “Accidental Empires” with Thirty years in consulting and writing about technology business with great success in predicting future trends. this artilce was about a project that showed communications and computing as well as entertainment can be delivered as a utility model leveraging free and open source software.

http://www.pbs.org/cringely/pulpit/2004/pulpit_20040930_000460.html

this article sparked 1000s of emails and calls and meetings with education.. govt and schools and companies.. and venture capitalists..

here is a second feature article in a magazine with 39 million subscribers... http://www.joleemagazine.com/pdf/JOLEE-Luxury-Issue-2011.pdf

Thank u for ur feedback.. i will post specific questions in their receptive areas.

thanks for making a newby to this form feel welcomed.

yes i am a 50,000 foot guy and a dreamer.. so i often get this type of feedback...

dewd... did u not see the bizz model i laid out? ALL profits are shared equally distributed to ALL that add value... employees.. customers.. suppliers... like a co op and credit union combined with a West jet kind of model..

this is a passion for me .. fun... not a get rich thing.. just to be clear...

what im looking to attract is people that share the passion and fun and want to make the ultimate Delta recumbent with lean steer and electric with full suspension....and potentially make it available to the market and have people that share this passion and desire to make a living at what their passion is...

Do u own a Apple IPhone or a Android? Im just trying to combine the best of both bizz models. Apple is an integrator... best of bread and best of fit... Google is Open Source..... just wanted to use crowd sourcing and open source model to make sure the profits and management are more evenly distributed and socially responsible and economically and eco friendly.

Cheers

Google is Open Source

Sorry, is this for real? Not wishing to be rude, but Google is just about the opposite of "open source". It collects data secretly and sells it for great profit, refuses to share that data with the individuals it took it from, robs people of advertising revenue, imposes draconian rules, dictates terms and conditions that are frankly unbelievable (if you take the time to read them) and as a company it rides roughshod over every single notion of individual privacy and personal freedom you can imagine.

Oh, and it's motto " Do no evil" has to be the most crass lie ever to leak from the mouth of a corporation, ever.

Thanks for the feedback.. yes.. i realize the power transmitted is not enough to power the vehicle on its own... right now just looking to reduce weight and cost of the battery and make it so people dont have to plug it in to re charge...

im looking at using the wireless power from this company in the TedTalk http://www.ted.com/talks/view/lang/en//id/619

I understand the principle very well, but there is a snag. The power you can collect from a radiated EM field decreases in proportion to the distance between the transmitter and receiver. For example, say you had a transmitter that was putting out 1000 W. With your receiver touching it you might get about 1000W (if you're lucky). Move your receiver a few metres away and you'll be lucky to get a watt or two. Move it a few tens of metres away and you'll be down to just milliwatts of received power.

If you increase the frequency you can make the transmitted power directional more easily, but the big downside then is that the beam becomes hazardous to people pretty quickly, because the field strength would get up into the region that's harmful to the human body at just a few tens or hundreds of watts, with a concentrated beam.

There's been a great deal of work down on this concept, primarily looking at ways to transmit power from solar arrays in orbit to the ground (the so called "power sat"). It's staggeringly difficult to do in practice with any degree of efficiency, and with a system that is intrinsically safe to the human body.

I do agree with all u said... that is more a factor of the US govt and the few families behind the corporations that run this planet... but thats an entirely different conversation.... i was referring to Android software.. which i agree is not entirely open source... but some what open.... but has over 1 million new activation's per day and over 50% of the market share... G+ now has over 150 million signed up... sooo.. seems google IS good at getting mind share and emotional buy in.... so they seem to be on track to appeal to and address the the needs wants and desires of the masses... that being said.. they do look like the next version of MS in a way...

sooo.. it sounds like u have a good grasp of what is not good about Googles model and business .... what do u see as being the alternative that would be better??? Please share.. there are lots of people to point out everything wrong... but they very often do not have any alternatives or offer a better way.... i frankly look for people that offer solutions and positive ways forward.... can u share ur model of what is better?

I see a day when there will be a global alternative to google that is non US centric and uses more of an Apache licensing and Red Hat bizz model combined ... and the revenue model is a micro transaction fee.... googles present model of selling ur profile to the highest bidder instead of matching ur profile and request with the best service or product or relationship is what i believe will drive googles making revenue from analytic s become obsolete... googles model will be driven to Zero the same as microsoft is now.. Microsoft sells software as a product and googles highly subsidizes their software and services with Analytic revenues.

google has its good and bad... as im sure u and i do too.... I like to focus on the good ... u get in life what u focus on... Gandhi thingy... i prefer to look at the good and attract good.. i do see the other side as well.

Some good.. http://www.google.com/green/

.... thanks for the feedback.. dream on is what i do best..

I have seen there are groups that are focused on each of these areas and looking to simply integrate all the best of bread and best of fit....

Great feedback.. sounds like u have a background and knowledge in this area.. thanks.. im not a code writer or an engineer... i only pay a geek on TV.. im buzz word savvy and logo compliant... http://youtu.be/QPDLMzrlkpc just a big kid... What about a Mesh Network approach? A repeater ....and also have the same mesh network and power transmitting allow data to me transferred as well..

even if it only initially serves the purpose of not having to plug it in.. thats a biggie for the mass market.. lemmings and dodos.. ;-0

So to be more down to earth and brass tacks.. i have been looking at the Shimano nexus 8 speed with coaster brakes to install on my Trailmate Funcyle and add a in line electric motor.. unless some one can point out a 500 watt or more geared electric hub that u can access the gears when peddling when now electrical power is available...

ive looked at the geared electric hub motors and .. well .. im lost.. too many to choose from... is their a comparison chart some where? which one would be reliable.. light weight and cost effective... power efficent work in all weather.. climb hills.. ? TCO? ROI?

i have been looking at the Shimano nexus 8 speed with coaster brakes to install on my Trailmate Funcyle and add a in line electric motor

That is exactly what I installed on my tadpole trike a couple of years ago. Last winter I replaced the Nexus with a NuVinci electric auto shift.

I prefer the NuVinci to the Nexus, but neither one lends themselves to a lot of pedal only operation for me due to the gear ratios and the fact that I can't even pedal a regular bike up much of a hill for very long.

Wowsers.. a Tranny with some Balls!.. is what the add said when i searched for the product.. LOL.

What size of wheel do u have it in? does it start at direct drive and go up from there for the gears? Im looking for a "bull low" kind of deal.. costa rica has some VERY challanging LONG hills.. one is 13,000 foot climb!

Thank u 4 this.... this helps me a lot.. looks like a good price too.. do u recommend a place to buy it? can u still select gear manually or keep it in a gear when its a tough hill? i see there is an older more robust version that has been successfully mated to work with electric motors.... NICE!

Any suggestions on a motor.. controller and battery?

my only experiance with electric motors is the Moskino Discovery i bought.. http://www.e-bikesdirect.ca/ .. the battery seemed good.. took 5 hours to charge but lasted a long time and says it can take 3000 charges.. seems light as well..

 

[Rassy]

The road up to my house has a 15% grade and my driveway tops off with a little bit of 20% grade so all of my gearing was based on these needs.

The transmission is laced into a 20" wheel and has an 18T cog on it. The gearing ranges from about a 50% underdrive to a 175% overdrive. There is no need to be able to manually shift it because you program it to keep the motor (and pedal cadence) where you want it. In my case the motor stays between 180 and 210 RPM while my cadence stays between 60 and 70 RPM. The big problem is that Fallbrook is no longer offering the N171B Developers Kit. I recently had a problem with mine, (developed a funny noise but still worked okay), and it looks like Fallbrook is going to come up with a new one for me, but still waiting. I already had two spares on the shelf just in case, so not hurting yet. Of course I can always go back to the Nexus.

The motor I use is just a slow wind hub motor with a 16T sprokett and the crank has a 48T freewheel.

The motor, gearing, battery, voltage, current, controller, etc. choices are unlimited and you have to build to suit your needs. It took some trial and error to get everything the way I wanted it. I'm happy with a top speed of 20 MPH, but many on this forum want a lot more.

For example, say you had a transmitter that was putting out 1000 W. With your receiver touching it you might get about 1000W (if you're lucky). Move your receiver a few metres away and you'll be lucky to get a watt or two. Move it a few tens of metres away and you'll be down to just milliwatts of received power.

As far as I understand it, that is assuming you are using directional transmission antennas, and that you are pointed at the actual transmission source. Is that correct? If so, then you would have much worse losses with omnidirectional equipment, which is what would be used for general power transmission, correct?


Alternately, the problem becomes that at greater distances, you require larger antennas to receive enough power to be useful, and it doesn't take very far for that antenna to be larger and more massive than your entire vehicle.

@andrewCR:
It is always useful to see the negatives of any approach, as that is how you find solutions to fix things.

So here's some more "negatives" that might point you away from approaches that are less likely to be practical, and let you concentrate on things that might be more practical.

Keep in mind that I LOVE gadgets, and have loved watching "sci-fi" technologies become real, over the past nearly four decades Iv'e been aware enough of the world to notice such things. But there are practical limits to the world, and money is needed to create things, and even crowd sourcing money has it's limits (easy to get money for a cool-sounding project during it's proposal stages, much harder to get real investors to keep pouring money in during development, especially once it turns out to be impractical or impossible to do what was proposed, and things have to change or be left out, or when thigns just plain take too long for whatever reasons).


"Repeaters" of any kind for power transmission would be highly inefficient, and useless anyway. Each one would have less power to retransmit, because of the losses to distance, and the losses internally in retransmission, so you would actually get *more* power simply going directly from the original source. Unless of course you are powering the repeaters from a "local" power source, and at that point you would be much better off simply transmitting the full power from each them to start with.

However you would need hundreds or even thousands of them just for a single neighborhood, and as Jeremy points out, the transmissions passing thru living objects at these power levels would probably not be good for them. (imagine potentially thousands of microwave ovens with their doors open but wired to run that way, all running at full power, just around the street your house is on).

Then you ahve the power bill for all of those, transmitting all the time. Where is the money for htat going to come from?

Then you have the power itself--a number of places these days don't actually even have enough power for everything that needs to run during the daytime in summer, and rolling blackouts can occur. This system (if it was big enough to cover the whole city) is likely to waste more power in it's continuous broadcast than all the residential electric usage combined.

You could make it not be continuously wasting this power, but rather turn on only when queried by a transmission from the vehicle, but now you ahve made the system a lot more complex, with more failure points, and more susceptible to RF interference (whcih is common enough as it is, and would be made worse by all of these transmitters running).


You *could* wirelessly charge the vehicle by having an antenna at it's parking spot, and a matching one on the bike, using inductive transfer or some other method (even RF if you like), but that's still yet one more inefficiency in the system in addition to all the regular ones that already exist. So either it would take longer to charge than normal, or it would have to have higher power draw, which if everyone did this would again increase the power load on the city's electric supply.

If you *only* had wireless charging of the vehcile, then you can *only* charge it at a very specific place, with wireless connection designed to be compatible with that specific vehcile charging system. If there could be a universal standard for such stations, it would not be as much of a problem, but I don't know of one yet, and it would probably take years to get people to decide on one and then decades to implement a system of installing them around various cities to the point they would be ubiquitous enough to be really useful. Especially since you'd have to figure out who is going to pay for htem all, and who will foot the electric bill for them.

If it can both plug in and wirelessly charge, you now are carrying more weight, and the batteyr will last less time for the same size/capacity, because you are carrying the extra equipment. Might not be very much weight, but it still affects overall efficiency/range, especially if you have hills or a lot of stops/starts, like in most cities.

Standard wall outlets are everywhere, so any charger that can plug in at home can plug in everywhere you go, as long as you can get permission to do so (which is generally very easy, with some exceptions). No infrastructure needed, it already exists. No special equipement to add weight, complexity, cost, and failure points to the bike is needed--decent chargers for onboard vehciles already exist, or can be manufactured with existing designs/technologies easily.

As far as I understand it, that is assuming you are using directional transmission antennas, and that you are pointed at the actual transmission source. Is that correct? If so, then you would have much worse losses with omnidirectional equipment, which is what would be used for general power transmission, correct?


Alternately, the problem becomes that at greater distances, you require larger antennas to receive enough power to be useful, and it doesn't take very far for that antenna to be larger and more massive than your entire vehicle.

Omnidirectional antennas are worse than directional ones, because of spherical spreading. The radiated power at the receiver can be imagined as that at the internal surface of a sphere with the source at the centre. As you get further away the energy density quickly gets much lower.

Directional antennas allow the energy density to be increased in the beam, but the beam won't ever be parallel so there will still be a reduction in power with distance. With a directional beam you also need to ensure accurate alignment between transmitter and receiver, plus, as I mentioned before, the energy density in the beam would quickly get to harmful levels for any appreciable amount of power transmitted.

The general rule is that larger antennas are able to intercept more power than smaller antennas, yes. This is one reason why decreasing the wavelength (increasing the frequency) makes sense for wireless power transmission. Antennas for high frequencies can be much smaller than those for low frequencies, as efficiency is proportional to wavelength.

This is a problem I've been chasing for a while: How to transsmit power 12 inches at 10% efficancy safely for a Park-And-Forget® charger. The answer is its virtualy imposable to do it safely.

You essentially need microwave to move this kind of power in a tight, aimable beam. For my test purpose, I would have needed a tiny 500 watts per square foot. Thats about the power level inside a microwave. About enough power to run a battery charger, or fry the family cat if it walked through the beam. Get the beam a little off, and you would heat up the electcal wires in the wall, or the roofing nails, or the water pipes.

Lower the frequency so you can disperse the beam into more of a cone, it becomes safer at distance, but less efficent, less usefull, with more incidental heating of surrounding objects. Anything conductive in the path of the beam will become an antena.

To tighten the beam up so you can move power over a longer distance, say, 100 yards, you need a MASER. Move enough power to run a bike, and anyone who walks in the path of that MASER's beam could be killed. And Who would want to sit on the bike while it was being shot with the MASER? It might be safer to power the bike by the kenetic energy of being shot with a .50 cal machine gun.

i have been looking at the Shimano nexus 8 speed with coaster brakes to install on my Trailmate Funcyle and add a in line electric motor

That is exactly what I installed on my tadpole trike a couple of years ago. Last winter I replaced the Nexus with a NuVinci electric auto shift.

I prefer the NuVinci to the Nexus, but neither one lends themselves to a lot of pedal only operation for me due to the gear ratios and the fact that I can't even pedal a regular bike up much of a hill for very long.

DEWD here is what came of u pointing this out....

Diesels are next to non existent in the scooter market because of the regulatory bodies saying emissions are not except able.... But are more ecconomical and have the bottom end torque needed for stop and go traffic... just need a transmittion that can make best use of the torque that is light and simple..and get rid of the emissions..

auto rickshaws, tuk-tuks

Asian Development Bank estimates there are over 100 million vehicles using two-stroke engines in Southeast Asia

In Bangkok, Thailand, two-stroke engines contribute 47 percent of pollution particulates in the air.

sooo.. how to make the biggest impact socially and economically as well as governmentally as fast as possible with the least amount of effort....

http://www.fallbrooktech.com/ combined with http://www.dynamicfuel.com/thirdparty/ combined with small cc diesel motor for Tuk tuks and mopeds.. scooters.. anything with a 2 or 4 smoke cc engine ...

Dynamic fuels reduces emissions of Diesel by 90% and adds more torque and with the Nuvinci transmition to make more out of that new found torque as well as being a lot lighter.. adds 30% more fuel econnomey...and the motor last considerably longer.... translation.... 500 miles to the gallon and 90% less emissions...and the drive train and power plant cost less and last longer with less parts and easier to repair... TCO ROI Cradle to Cradle

catalytic converters reduce fuel economy and when disposed of are a huge issue for the environment...

U gotta love Nuvinci advertising "Our Tranny has Balls" LMFAO

I am an advisory to the board of Dynamic fuel.. i put all parties in contact with each other and the BALL is rolling fast!

the Honda Super Cub is the most produced motor vehicle* in history.

the 49cc motor is the most massed produced motor in the world and is seeing incredible growth in Modpeds and scooters world wide.

electric and gas 2 stroke have issues... need more torque for stop and go for gas... electric.. heavey batteries... what emissions come from the electricity generation and u loose 40% in the transmittion lines to get it to u.. step down transformers.. etc etc..

here is an example of a 18cc diesel motor from 1950 that gets 350 miles to the gallon!

without dreamers... life is a nightmare.. presently.. the world loooks like a nightmare to me.. support dreamers... and u will live the dream...

Nuvinci inventor was a backyard guy.. not an engineer.. just had a personal goal to go faster on a bike... a dreamer 4 sure!!!

dewd.. contact me and im happy to compensate u ... maybe some shares of the company????

and tooo be back on topic.. u can add a electric generator to this and share wireless electricity for a ultra Wide Band wireless mesh network nodes using IPV6.. look it up.. its a unlicenced spread spectrum .. 1 GB free wireless network..

Dieselbike.net has lots of guys changing the gasoline engines to Yanmar small tractor engines. No problem getting them licensed legally.

I almost went that way, before finding this forum and it's quality members.
