Unless they make some serious dope deals somewhere, I can't see the money coming in. I mean why would it, if it hasn't over the past year or so? What has drastically changed from then to now that would make someone say, oh awesome, here's some money?
As far as cell tech, not getting into that mess, seen too much happen both ways to take sides there. Pouches / Prismatic, if you can keep them cool and keep the power density up, go for it. Engineering wise, on paper, a pouch (read polygonal shape) ie 90 degree angles, ie NOT circular, makes much more sense because there is a lot less wasted space than between the circles. But ON that note too, if it needs cooling... send the cooling down those wasted space channels between the circles, you already reserved the real estate, now put it to use!
I think we pretty much are about at the end of the current tech for battery chemistry and motor design until someone comes out with a new chemistry with better power stats. You are not going to squeeze much more out of the current chem. Motor design you can fiddle and fuddle with a bit, but ultimately they have not changed very much over the past 100 years. Make them dense to run more power thru them, IF you can keep them cool. Right now, use the exotics in the laminations for more flux density, but ultimately... like any power transformer, which a motor, really at it's core, is a rotating transformer with it's secondary shorted out, once you have saturated the core, improvements come screeching to a halt. No higher voltage is NOT going to help once you saturated the flux at the core, all that does is tend to make ringing and eventually kaboom !
Still, I will say, yah Id love to see a 200 MPH e bike. Don't care what the HP is if it can make that speed and do it quickly.
As for torque, well once you popped the wheelie, MORE torgue really is moot at that point, once you turned your tires into a burning ring of fire, more torque is really moot at that point. To get you from 140 to 180 in a few seconds, now you need torque, but all this fuss about how fast a bike can 'theoretically' go from 0 to 60. Mostly hype. How many can you actually Do that as is out of the box, and actually be able to DO it without messing with tire pressures, balancing and all kinds of other crap because the bike wants so stand on end it's so powerful? 0 to 60 in 1.4 seconds IF you ever figured out a way to hold on.... ok whatever. A car, all those G forces are pushing you snugly into your seat, you are still in control, a bike they are trying to rip you off the bike... a bit of a problem there.
Your turn
