I think we were talking about this in another thread, but I found some interesting theory about how the electric grid will deal with all this demand in the future. It boils down to having multitudes of electric vehicles plugged in at all times. If a standard can be developed that allows 2-way charging, when the grid gets a spike, it pulls current from all the plugged in vehicles. As the vehicle owner, you can opt in or out, or even be compensated for the electricity that is pulled from your battery.

I encourage anyone interested to read both installments of the "Electric Terry" interview on New Atlas, but he specifically talks about this issue in part two:

IIRC, my concern was like a motorway service station, many miles away from large cities and/or large generating stations. Exactly where you might have to charge your car, at least partially, in just a few minutes.
While many car batteries might serve to buffer the grid, there must be a connection between the grid and that far-removed motorway service station, basically an umbillical extension of the grid, to a place where there won't be cars nearby to offer up a charge.

I guess they would install a massive battery or capacitor at that service station. But it would still need a substantial power line to charge up during non-peak hours, and to have some extra capacity for rising demand or situations with unusually high demand. Suppose they only need those 10.2 MW I suggested for two hours per day, and average 0.5 MW over the remaining 22 hours (that's probably lowballing, I'd guesstimate). That's 31.4 Megawatt-Hours per day. To give a safety margin, make it 36 Megawatt-Hours per day. That would still require a 1.5 Megawatt power-supply to satisfy that demand, and charge up the gargantuan battery they'd have to have, running 24/7.

And that's a single mode of failure. One powerline fails, and hundreds, if no thousands of cars might get stranded in the middle of nowhere.
So to make sure it works, you'd need at least one more connection to that distant grid, one that can handle the same load on its lonesome.

Alternatively, one might install a bio-gas fueled gas-turbine generating station at one such distant locale, one that fires up whenever that long, long line fails.
I did the googles, and a 1.5 MW natural gas fired generating stations would cost >US$ 1 million to install. A busy motorway service station surely is expensive already, these days.
But take that US$ 1 million, add to that the massive cost of the buffering battery, and the long powerline(s).
I guess, quite possibly, the cost-effective solution would be no grid-connection at all. Just installing a couple of redundant generators, and large battery, and deliver biogas or synthetic hydrocarbons by truck. Would be a lot of trucks. But shouldn't be much more than the trucks presently delivering the fossil-fuels that such a remote service station is presently providing, so that should work.
If there were absolutely anything to be afraid of, don't you think I would have worn pants?

I said I have a big stick.

I'd seen some pix of the newest ̶C̶o̶n̶f̶e̶d̶e̶r̶a̶t̶e̶ Curtisss bike, I hadn't clicked on any of the articles to learn that J.T. Nesbitt is actually back on the design team there. I dig this Hades WAY more than the ridiculous looking Zeus. However, like all the other post-Wraith, post-Nesbitt ̶C̶o̶n̶f̶e̶d̶e̶r̶a̶t̶e̶ Curtisss designs, it looks like someone got a new CNC Machine for Xmas and just HAD to build a motorcycle. Routing and 45deg chamfers everywhere, but it just doesn't appear "finished".
Anyway, the specs look pretty awesome, but the 217HP and 147 lb-ft spec is the first e-moto I've seen w/ a higer HP number than torques.

I hope they build it!

Hare scramble on a Sur-Ron electric Freeride bike. 16 miles in 58 minutes. The Sur-Ron is about $4000 and is sort of a mountain-bike motorcycle hybrid (no pedals) i.e. small lightweight and uses some bicycle suspension components.

His battery quit just a few turns from the finish. It was fun to watch the end and hear everyone in the pits going "What is that thing?". And the rider getting lots of congratulations.

Great interview with an engineer who's been building e.Motos since 1989! Worked with AC Propulsion (pre-Tesla), Brammo, Victory, Zero & it's currently building diy trials bikes.

The Sur-Ron is a neat little trail bike with about 125cc's worth of power. Apparently just bought or licensed by Segway. Hopefully the price doesn't go up. It's around $4000 now.

Here's one riding alongside a KTM500 for comparison's sake.

Damn! There was a Livewire demo ride right near me in August and I had no idea! Grrr

https://youtu.be/VUoYEGFcamA

Not the most exciting video, but this was just down the street from me. I should have been there!

Livewire deliveries are happening, so we're now getting some first-hand owner's videos. Here's a 0-whoa! video showing the crazy acceleration:

That looks fucking quick! And so stealthy!

So yeah, cool fucking ebikes. But still, $30,000 is crazy.

Your gubmint wants you to buy an electric motorcycle sooooo bad that they're willing to "give" you $2500 to do so:

I've always loved to see a bike's engine. The go bits. Pretty high on my list of aesthetic qualifiers in a bike, to my eyes, is the mill.
For a tupperbike, this looks great, yeah. In absolute terms, I'm not loving it.
I know that the electric bike future won't be making with the pretty engines anymore, but that's actually one of the things I dread. The end of what, to my eyes, are beautiful motorcycles. Those that show off sexy bits.

I kinda like it as well. If you can ignore the dark bits, the bodywork looks a lot like a bird launching itself into flight, to me. I give them credit for a fairly-beautiful form on a platform (electric, generally speaking) that hasn't had many beautiful designs. No, it's no 1934 Henderson, but it has a lot more visual appeal to me than what confederate curtiss put out: that thing just looked to me like a dog about to hump a pillow.

I do have to agree on this point. There have been some beautiful engines in the past, but I've also been annoyed recently by the dress-up with false parts to make an engine look more traditional... specifically looking at you Triumph, with your fake carburetor covers for throttle bodies, useless cooling fins (ok, maybe not useless, but definitely unnecessary on liquid-cooled mills), and so forth.

Image

I mean, it's one thing to make a functional design beautiful, but it seems like regression when you start dressing it up as something it's not.

It's one of the reasons I liked the new Scouts -- they make no bones about being liquid-cooled and modern. They didn't try to recreate the old Scouts, they just made a nod to it.
