... ... it could potentially work out with daily charging. Interesting that the industrial PV systems have a much lower LCOE. Has me thinking a field install may be a much better option. I have some room with good exposure fortunately. If you can charge direct during daytime, and/or DIY the system,...

Around $2.8 to 3.8 (with battery). Around 5.5 -7.5 year payback. How long do they live and what are the typical associated maintenance costs as they age. Given a 15 -20 year life cycle, what is the typical cost to produce a kwh for the average location- system. NO, you cannot generalise like that.....

In Cali, the best selling cars now are the Mod Y and Mod 3. @ 21812, 21506 units. Rav4 was third @15990. Anyone know the avg cost out in $/kwh for the average home roof top setup if you can afford the roof? :lol: Looks to be approx $2,800/kW. .....Without storage.(+$1,000/kWh) https://www.energysag...

You seem to have messed up your meds again ian..!

You'll have to excuse HH. He's been huffing his own tailpipe for so that long he thinks the problem is the solution and the solution is the problem. So you are saying the solution is to deconstruct a functional utility grid to the point where there are widespread power outages,?.. ..leading to the ...

In short, it is the result of dumb political commitments to “Net Zero” etc limiting the use of those fossil fuels, and hence forcing the closure of coal/gas generators without installing a workable alternatives ( only Wind & Solar). What is their thinking? That ‘Stra’ya's catastrophic wildfires...

. One issue is that conventional light-sweet crude peaked in production in 2005. Unconventional production may have recently peaked as well, but it's too early to tell. It will at some point in our lifetime if it hasn't already. ....... OR... its mostly down to “new US politics” screwing up the wor...

‘Stra’ya ( :) ) generates most of it's electricity from coal and gas? Yep !... ...BUT the reason for the power price increase is nothing to do with fuel costs ( ‘Stray’a has plenty of Coal and Gas ! ) In short, it is the result of dumb political commitments to “Net Zero” etc limiting the use of tho...

Just a reality interuption here... We are dealing with these current high fuel prices, which are jacking up the costs of transport for sure.. But, down here, (‘Stra’ya ) we are also beginning to see the impact of the current world energy situation impact domestic electricity prices,... which are del...

I dropped my battery like an idiot, and one of the cells got bent. Is this dangerous? Should I replace the cell? That is not “bent” ,..it is severly damaged and consequently a major risk of failure and fire. Fix it ASAP !...and in the meantime, put that pack somewhere safely out of range of any fla...

I have noticed that this “Motor Technology” page is heavily integrated with “Controller” threads.
Is there not a good case to set up a separate forum page for controllers, to simplify searching for motor and controller information ?

No, I sat in a Mazda 3 and its small but I had lots of layers on, .........
Mazda 2 is even more smaller, ........

On the outside ,..sure !
But the space inside for the driver is not !

What year and model of Mazda is it? I have been looking at the 3, 4, 5 and 6, 3 is to small, prob 4cyl, Mazda 6 is 6cyl but more spacious for tall folks like myself. I have had an old Mazda 323 once, very small but I fit in it good enough. If you were ok in a 323, then you should be good even in a ...

Most solar users “reschedule” their usage, ..washing , drying, water heating, cooking, etc etc, ..to occurr during peak solar periods ..i assume you are doing that ? But still. 8 kWh at best is a hard to meet, low usage level....so yes an upgrade to both panels and storage would seem logical for a c...

Doesnt it just have an existing spin cycle that you can use ?
Or take a look at this thread..

Here is an example of a “lay down” aero kart..

Toaster
Kettle
Microwave
Coffee maker
Dryer
Dishwasher
Fan heater
Pool cleaner
... that is just the ELECTRICAL appliances that have had to be replaced since January this year
In addition the washing machine failed, but was repairable , and a TV ( 2 yrs old) is acting up, but is being ignored !!

Karts are an aerodynamic brick !...anything above 30mph pumps power into the wind.
You could reduce that time, and increase top speed if you just tilted the seat back to a “laydown” position.

Big cargo bike designed for climbing mountain roads with 500+ lb loads, they'd be just fine

Sure , they would work, ....but EV cells would be save a lot of extra weight.

Trade the 308 in and buy a Prius ...!

I hope you aren't trying to say there's anything wrong with Winstons / Thundersky? There is nothing “wrong” with flooded lead acid either,...for some applications ... such as car starter battery. Its a “horses for courses” situation ! But, Winstons or Thundersky in the context of ebikes, .. they ar...

Good news !
How are you dealing with chain play now, without thr excentric adjustment !

I haven't heard why investors are avoiding Rivian right now. Maybe a weak quarterly report? Ford selling off their major shareholding in Rivian , probably did not help ! Several for sale right now... if you have the money. https://www.cars.com/shopping/results/?makes[]=rivian Most reviews I've seen...

.note the wall thickness around the bottom bracket cannot be over 8mm (only an issue on some custom or carbon booms),... From that statement, it looks like you would need a customised excentric sleeve, ( maximum offset, ) to get the Tsdz2 spindle as close as possible ..3mm or less.. to the bb shell...

At last it is alive and taking orders..
