I agree. In addition to burning up more coal. What money will fund the extra demand on the power grid? Answer. All customers of electric power if they own electric cars or not.

"By using electric instead of fossil fuel-powered vehicles, there should be a net reduction in greenhouse emissions" - I seriously doubt that. Electrical power in USA is mostly derived from burning coal so the net greenhouse emission will be higher...until you replace coal with wind, solar and nuclear, which will be 30 years at best, and never the worst case, you are adding extra burden to environment

By using electric instead of fossil fuel-powered vehicles, there should be a net reduction in greenhouse emissions. Public charging systems could be made to sense the presence of a car needing charging, sense the degree of charge the car has acquired, and turn themselves off when not being useful. And of course it all needs to be considered in terms of the cost/benefit including carbon calculations. Anyway, it was just a thought.

I hope those going thru this wastefull convienience suffer personally thru extreme weather events that they are helping to create...reasonable governments throught the world should not approve this way of charging vehicles in public...Kris

And further degrades the value proposition. Imagine that waste x millions of customers, all of ta sudden we need 105% efficient converters to make up the difference

I cannot imagine that the wireless charging is anything near as efficient as plugging in directly. But I expect that many consumers will prefer it anyway because of convenience. This way you don't have to remember to plug your car in before you leave the garage.

It may also be possible that public wireless charging stations will become available, to encourage electric vehidle use in cities. If someone could drive for months without ever needing to worry about "fueling" their car these might become very desirable devices to urban dwellers.

Just as long as they carry a backup cable in their trunk for those times they are parked where wireless charging is not available.

Presumably wireless charging is less efficient than using the wires...so how much longer would you have to charge?
