Other than the contact brushes, there's nothing but air between the armature (rotor) and the stator. (well, the bearings, but they're designed to turn) The "drag" is actually from the magnetic forces trying to come in contact with each other. Not unlike trying to get Wifey to drive past a Walmart without going in!!

Good luck with that!

Electric heat is 100% efficient.

Electric heat does convert practically all the energy used to heat: However, electric heat is VERY power-consuming. Volts x amps = watts, thus Electroken's 1 hp = 50 amperes means about 600 watts of power, at 12 volts (I know a 12v battery actually produces over 13 volts, just simplifying). Those little electric heaters we use around the home usually have low settings that use 900 watts. high settings that use 1500 watts. Although they are 110 volts, watts are watts. The amperes used by those heaters at 110 volts is pretty low. If you had to produce 900 watts at 12v, it would take 900/12= 75 amperes.
The Elio will probably have an alternator producing 55 amps or less.

As an addition to this comment, the high current needs of electric resistance heaters has been a major challenge for electric cars. Electric heat is a major contributor to the significant range reduction which has been seen from EV's in cold weather. Electric vehicles which use liquid cooled batteries, such as Tesla, actually have an advantage as they can use this coolant the same way ICE vehicles use engine coolant running through a heat exchanger to heat cabin air.

Hmm.

Back in the day, (not that far back, really!), we sometimes ran into issues with trucks and vans, especially when they were used for towing, or had a camper added on the back. As I recall, the stock alternators were rated at 35 to 60 amps or so. This caused issues when additional need for current was needed. By researching, we found the "same" alternator, only meant for a different vehicle. (high end cars with power everything).
All we had to do was turn the back half by ninety degrees and it would bolt right on! No more issues after that! (around 100 amps as I recall). I did it for our old tow truck, as well as my own 1978 Chevy truck, as I often used it to go jump other cars during the cold Winters.
I believe the output capability of any alternator is determined by the amount of wire used in the stator. More wire equals higher amperage. Or, to put it into terms I easily understand, Wifeys Walmarts are close to each other and bigger!!)

Ahh...so the 'W' in Ohm's Law stands for Walmart, not Watts. Makes perfect sense now!

The Wifey/Walmart density should be the new standard.

I've lived with that standard for over 28 yrs. now..

Who are you and why hasn't Paul put you on his payroll yet? If you're good enough to work at PNNL, you're good enough for Elio motors. Love you G.O.

per a conversation with Jerome Vassallo, VP of Sales at the exhibit in Charlotte on 12-6-14 .... the AC will be electric, the type used in the back of a Chrysler minivan .... no compressor attached to the motor .... they don't want anything pulling power off of the motor that isn't absolutely necessary
