- kleiba 3y agoPerhaps with today's technology, but not with the technology of the future (tm).
- amenghra 3y agoWireless charging for some devices such as phones is 60-80% efficient. For cars, it seems to be in demand per "Several Companies Developing Wireless EV Charging": https://www.notateslaapp.com/news/1235/tesla-is-developing-its-own-wireless-charging-solution https://www.notateslaapp.com/news/1235/tesla-is-developing-i... If we can dream of self driving cars, we can dream of self-connecting cars. Something a bit like a toy slot car?

- nntwozz 3y agoNice find and that's not bad actually! Still wasteful though, it adds up quickly with the amount of future EVs. Wouldn't some kind of dock with a flexible MagSafe-like (MacBook version) robotic arm extending from the vehicle be viable? If convenience is the goal then there must be another solution without all this waste.
