17 moving parts in the "motor" not engine. I'll leave it up to one of the smart guys who reads these posts to point you to where you can find that info (& to fact check it). In my new-found Hollywood fame, we call those people groupies! ;-))

Rather be a fan or enthusiast instead of groupie, but here is a response:

I suppose it depends on what you are counting... Wheels? Half Shafts? C-V joints? Differential Gears? etc...

So that "17 moving parts" quote was for the original prototype (2 speed gearbox) powertrain (whole powertrain, not just motor) that never made it into production.

Wow, the number of crackpot comments in that thread gives me pause... One suggesting perpetual motion machines with scoops in the hood that generate power as you drive (violates first and/or second law of thermodynamics). Another suggesting covering the car with solar cells to charge it continuously in daylight (the sun delivers about 1 watt of power peak per square meter, so the surface could deliver a few watts total in reality).
12 moving parts. Would be interesting to see the breakdown. Exactly how do you define a moving part? Does one separate the rotating parts from bearings and list them in their own categories? How many comparable moving parts are in an 8 cylinder ICE's engine/drive train? 2000?

Yes, the early blogs and forums used to be overrun with that stuff a few years back. Thankfully I think people wised up and were otherwise enlightened.

That can't be right. I've certainly seen solar panels much smaller than one square meter that claim to deliver much more than 1 watt of power. Example .75 sq meters, 100 watts Amazon.com: Instapark® 100W Mono-crystalline Solar Panel, 100 Watt: Patio, Lawn Garden Certainly not cost effective but a few of these on a vehicle sitting in the sun all day should translate into a few miles of range.

Not exactly. One moving part in the motor, or three if you count the two bearings as well as the rotor. If you count the individual rollers in each bearing, well.....
The Sun delivers over 1kW of power per square meter on the surface on a sunny day. I had to work it out a few times for an astro exam in January and I think the simplistic theoretical figure was 1.4kW. Solar panels are however only roughly 15%? ish efficient, so that's why a small area has such a small available power. One interesting question we had was to work out the insolation on an area occupied by a coal power station. If you could convert all of the solar power (impossible, 100% efficient conversion), that area would put out more power than the equivalent coal power station. Cool stuff, physicists know how to have fun.
Plan on milking it until my next cameo which debuts this month.

Soon, I'll be having my agent (does anyone want to be my agent) answer these posts! ;-)
Hmmm... can you say Fisker
(look for fine print disclaimer stating it is just for cabin cooling - but look for innuendo that it charges the car)

Well, those first ones were "locked in 2nd gear". I am not sure if that means that they removed some parts. In any case, those don't exactly count (IMHO) since they retrofitted them with the more simple drive-train as soon as they could.
