Its been a long time since I watched it but wasn’t that kind of the point?
If you have 10 cars and buy an 11th thats electric you’re not really solving anything. The problem is overconsumption moreso than method of propulsion, the bulk of a car’s lifetime emissions are a result of manufacturing rather than daily use.
IIRC Spax and GRK make torx multi-purpose fasteners that you can use for wood and metal
Is there any more in-depth analysis to show how many EVs would be needed to make this feasible, how this would work with time of day use of power from commutes vs generation from solar power, how long the grid could stay powered this way, impact on consumers range, etc? I think the concept seems simple at first but would it actually be resiliant relying on just EV batteries? A cloudy week could see everyone run out of power, for example.
It costs money and the upsides are more than a quarter away :(
