Inductive charging will waste a bunch of energy.

[–] NotMyOldRedditName@lemmy.world 4 points 1 month ago* (last edited 1 month ago) (1 children)

Inductive charging has come a long way and doesn't have to have as big a power loss anymore.

E.g this government research project had 120kw at 97% which is on par or better with existing fast charging methods.

Edit: Also anyone charging on a regular 120v outlet, which is really all most people need for at home charging, is in the low 80's. Also Wiferon has ones commercially available at 93%.

I'm curious why you are downvoted?
When searching "wireless charging efficiency" on Google, Google offer this short explanation:

The efficiency rate of inductive chargers usually falls between 70% and 80%, though some newer models boast efficiencies closer to 90% under optimal conditions. This is slightly lower than the 90% to 95% efficiency rate often seen in traditional wired charging.

Not too far off from the statement above that 93% is already available, and apparently progress is being made.

Sir/Madam

You appear to be wearing the wrong glasses. Try these ones one

OP: Tesla BAD! How dare Tesla!

Me: Tesla doing this doesn't mean it's going to be bad!

Hope that helps.
