100 miles on 1kWh? What are you smoking? I'm pretty sure even an electric bicycle can't do that. Al  You would be mistaken. Stella Era did 1,200 miles over two days using a 1,250kwh battery and a 1.25 kw solar panel. That's pretty close. Lawrence Rhodes. -- next part

Nothing beats the efficiency of a properly designed solar vehicle that can collect energy anytime the sun shines. With a 12.5 kwh battery, 5 seats. 1.25 kw solar panel .15 coefficient of drag, 45 mph speed and a weight of 850 pounds the last interation of the Stella (practical solar vehicle)

Re: [EVDL] EV Distance Record Smashed

Assuming this team drove their car continuously (24h) for those 6 days in the smooth concrete-floored hangar, then they did an average 11 MPH which means that fact alone got them 25 times lower wind drag than at 55 MPH. They also likely used extremely narrow and high pressure tires, again slashing

Yes I know this is a very controlled situation and is not a vehicle that would be purchased by the public but taking a look at the numbers and doing some comparison with say the Aptera one might think the concept is promising.   Efficiency is a key component, same general shape, drag coefficient
