Hello,

The record is really great. But I fear it was for 24 hours and not a single charge.
My brain rang alarm bells when I read the battery only weighed 400kg and the car was relatively normal looking.
The car has a 27kWh battery which would mean about 15wh/km for the single charge.
The 2142 km was in 24 hours so it wasn’t done at 40 kph either. The car is streamlined but nothing like
a solar car. They use about 10 wh/km, I know at I am a satellite member of one of the teams.
The car is still an incredible achievement.

The best car I know is Japan’s IZA prototype from 1992. Using only NiCds it managed 547 km per charge at slower speeds and 300 @100kph.

No doubt there is a conspiracy against the electric car. Edison used to travel 200 miles per charge routinely
100 years ago. Now the cars makers won’t even offer 100 miles. Build your own while you still can. I have just started.

Maybe but other things to consider.
Power in batteries are proportional to voltage square. We don’t know how dangerously high voltage level were used. Even human can push a car, so chances are 1hp is more than enough. So car has very low acceleration and probably 5-20mph speed limit.

Secondly, charging limits. Even with low range, charging time is expected to be 6-12hours.

Other factor include battery cost and safety.

There’s risk factor for recalls also. Things like cars require taking it slow.

Finally there’s some pressure from oil interest. All of them are probably customers in one form or other.
