Comment on Detroit's newest road can charge electric cars as they drive on it
BearOfaTime@lemm.ee 10 months agoYou missed the 50% loss. Wasted energy. Means you have more infrastructure delivering electricity that isn’t utilized. Means you have more production that isn’t utilized.
And batteries already have a loss of up to 20% during charge from heating.
Yeah and who uses the energy that is lost? Nobody. It’s not a 50% loss to a driver, it’s all gain over the last charge stop.
As someone who did 500 miles this last week in an EV with 2 little kids, let me tell you it would be fucking worth it not to interrupt my sleeping children even if it’s not 100% efficient.
Electricity isn’t free. Convenience doesn’t make things a good idea nor economically viable. Need to charge on the go? Overhead catenary charging is a technology that’s already developed for use on vehicles and solves the efficiency issue.

Sounds like the next step is to power it using renewables so that we reduce that inefficiency as low as possible

It didn’t reduce the inefficiency though. You still have 50% of that power being lost, which means you need 50% more renewable generation. It’s wasteful.

That’s the good thing about renewable energy, we can waste some without it being a big deal.
Efficiency was the wrong word, but I can’t find the right one.

um not really. Renewables aren't completely free. Solar panels, turbines, etc. They have to be replaced. with 50% efficiency loss your talking about twice as much mining and manufacturing of the renewable infrastructure. That produces carbon and waste like anything else and more use of limited materials.
