wow! to make it perfect, you could make the wires more accessible for maintenance, link them to the engine directly so you don't waste energy in a polluting and dangerous battery, and bc the road is fixed anyway, link a ton of cars together for capacity and introduce regular stops for ppl to get in and out

14kw you need to drive around the world twice to charge up 10%

Wireless charging has a power loss of 30%. Although for this application it's probably even higher. Far too wasteful to be practical for general consumer use

actually charges at a decent rate as well not miniscule

No country has the power infrastructure to support this en masse. You're pumping electricity into the ground that loses 30% of it's energy when it's being used.

you guys don't appreciate any effort. I want to see a single person that has proposed a single idea as brilliant as this one to help humanity

Why don't they also tell you that those coils are powered by a coal burning plant. 😏

Or.. just build trains which can also: carry more people, are more efficient, and takes less overall maintenance for individuals

People arguing that you're still losing power as if gas cars regenerate anything at all 🤨

SON OF A B.... I had this idea back when I was 12 years old but never thought it would work.

what it's gonna cost to repair such roads? how complicated will it be? It's bound to be deformed over time,so they should relay the charging infrastructure every 10-15 years FOR EVERY CHARGING ROAD.

Okay but that must be SO inefficient. Just wirelessly charging your phone even though it's basically touching is extremely inefficient compared to wired. Imagine while you're moving and with a big gap

I used to have a dynamo on my bicycle in the 70's. Movement charges. So why do we not see this simple technology now on domestic vehicles

sooo.... what is the point of this if we already have trains than can transport waaay more people

During drive, the tyres can be considered generators, surely that alone can charge it with the relevant devices...Unless thats how they gonna charge road tax per mile..

Great idea, but we cannot fix a pot hole for 6 months in a road, never mind replace the centre of entire motorways with tech.

Meh. Not realistic on a grand scale and too much powerloss. Maybe for taxi's queuing at airports. That seems achievable.
