i would have given this guy credit if he compared cost of production for petro fuels when talking about energy debt.

also conflates power with energy, but fine.

if you talk about cost (dollar or kilowatt hour) per joule delivered to a vehicle and then compared the total cost of electric vs. the total cost of petro, i would listen. but he ignored the fact that petro fuels cost money, energy and water to produce.

and there some things electric motors can do that ice can't. an electric ekranoplan isn't too infeasible, but we know from soviet studies you can't keep salt water out of an aspirated motor when you're that close to the water's surface. turns out electric motors can be sealed against water.

and dissing physicists? wtf? makes me think he failed out of an engineering physics degree cause he didn't understand math. as we used to say, the limit of a bs or be as gpa approaches zero is bba.
