Stop trolling. You cannot possibly be that ignorant or misinformed. There's literally 70+ pages of him being that ignorant and misinformed. Economics, scientific principles, energy market dynamics - it takes impressive dedication to be so incorrect about so many topics! The oil age will not end for...

I have no doubt Tesla is a stressful place to work, given what they're trying to achieve that's pretty obvious. Yes - they're spending money, however that expenditure was all to achieve the required scale to achieve the vision. Elon has freely admitted they pushed too much automation too early with ...

Marcos what if Youtuber Gerard Morin is right, that these larger drum motors work best with higher voltage + higher frequency rather than higher current? How easy would it be to modify to have lets say an output of between 240-500volts and a frequency range between 15khz - 25khz. In one of his last...

For 20km you really want a bike. In a shared space/sidewalk scenario your speeds are limited on small wheel devices (and laws if you care about such things). Realistically you're going to struggle to do that 20km in <1 hour on a smoov or similar. Most longboards will have greater speed potential, bu...

Yes actually, I was contacted by a rep from Mobipus - they're in production and available ex stock apparently, both the 200a and 600a units. No idea what that means for anybody that was previously left in the lurch. $280 USD for the 72200 $25 USD for 72200 heatsink $35 USD for 72200 water cooler $88...

Awesome, very keen to see it. Do you know what wheels you're going to order?

Still got quite a long time before I get mine, right hand drive cars are a way down the priority list I'm sure. I ordered before the reveal event even began, so hopefully I'm early on the Australia/NZ list at least!

I have just received my welder, looks absolutely fantastic. Very impressed with the design, quality of the supplied hardware and components, the leads and probe tips look great. In addition the documentation is fantastic . This is an area often overlooked, but great doco is essential for a product o...

Unfortunately you are using a hub motor so gearing is not an option. Your hub delivers the RPM's and torque it does until it runs out of KV's. A mid drive with a modded Peerless 700 transmission will give you both...speed and torque and do it for cheap. Shifter kart racers use this little transmiss...

So I am partialy a newb but if I bought Bitcoin in 2013 and held it and now I have both bitcoin cash and bitcoin SWEET!!! Anyways my question is if you put you Bitcoin on a paper wallet does this still count? Or did it need to be saved on an extange online? Mine was online and I was seeing bitcoin ...

I suggest you look into the segwit/lightning network and form your own opinions, I'm confident bitcoin will be around, but I'm much less confident it will be the current BTC chain. An amusing write up for the uninitiated: https://hackernoon.com/chapter-one-alice-and-bob-9fa315aeef62 If you held bitc...

We would see those prices if current rates of speculation were to continue, however I don't think it will for a couple reasons One, Bitcoin is currently broken. In 2013 I could send a transaction in minutes and it would cost <1c. Today to achieve the same confirmation time you may need to be *hundre...

Looks awesome John! Seems likely you'll beat me to it! I've now got my workshop somewhat set up, CNC up and running etc. Unfortunately still limited time to work on the bike, but have made a little more progress on the swingarm modifications. Need to do some routine maintenance on the daily ride how...

On my bike around town I have only once managed to get a trip above 35wh/km. That's riding as fast as possible on road, 70-85km/h, full acceleration (~12kw) where ever possible. It would be a molten pile of slag if it actually *averaged* 65 wh/km. The city range will be substantially more than this....

This thread needs more disassembly pics! Anybody got one of these things that they can pull apart and document? The frame, motor, drivetrain all looks great. Battery looks pretty good too, but odd cell choice - I'd definitely be replacing them with some Samsung 30q's - they're just better all round ...

I think what makes it special is the ability to run lots of power on cheaper controllers, which is less important with the modern generation of controllers, and the high efficiency due to the thin laminations, and the low phase to phase resistance keeping the heat losses down. So not just its raw p...

..... Did anyone see 60minutes Australia's report on renewable energy? It was pretty amusing and disturbing on how misleading it was, very well presented, someones already uploaded it to youtube https://www.youtube.com/watch?v=5g8DD01B89g. .... Yes, and at least they managed to highlight the precar...

These things are very interesting. I really like a lot of the design choices.

First reaction to the test ride video, damn that's loud! Clearly doesn't have a sinewave motor controller. This paired with a better controller/72v battery would be great.

Lotus Lotus is not slippery, has limited to poor battery mounting options (see Tesla Roadster), and once the lotus goes much over design weight it handles relatively poorly. Luke - have you seen Sasha's Lotus Evora running Tesla drivetrain combined with two Volt packs? Built as a street/time attack...

Never??? How do you figure natural gas will never become scarce? There is no debating a huge dependence on gas heat and industry. Only 40% of gas is used for electricity right now. which won't go down the more peaking base load is pushed onto it. EIA states 90 years. I might guess 150 being optimis...

+1 for Hubsinks being awesome. These combined with Statorade on my QS 205 on the street has banished even the thought of heat issues. My ass or battery capacity (who would have thought 2.5kwh wasn't enough a few years ago!) is now the limiting factor. Thanks for the huge community contribution Sketc...

Or natural gas? . 90 years left. Then What? It gets mighty cold in the winter. . https://www.americangeosciences.org/critical-issues/faq/how-much-natural-gas-does-united-states-have-and-how-long-will-it-last . https://www.eia.gov/tools/faqs/faq.php?id=58&t=8 . lol - what alarmist bullshit. You real...

Amazing work Arlo! Once you CAD you never go back... Design is incredibly elegant! How are the driver boards going to integrate with the package?

Thumbs up for laser/waterjet cut bus bars. I might have missed it, are you going to have this one air cooled or integrate a waterjacket?

If the ABC pounded Australians with modern science about how much they could help cut co2 emissions by carbon sequestration/forests instead of covering them with solar panels we might actually get somewhere. Every time I see clueless Australians parrot rubbish information I continue to dream about ...

I ran my mini-e at 7.5kw for well over a year of daily riding, that was certainly about the limit for reliability however. My QS 205 3.5T killed it as it's a bit harder to drive and I was already right on the limit. The Adapttos are very difficult to establish correct timing on however, many people ...

Glad you came to your senses! I have one of these motors, they're incredibly good compared to most other hubs. Two Sabvotons or Kelly controllers and you can pretty easily run 20kw.
