crazy nonsense

Neither crazy nor nonsensical. John Larkin can't understand it, but he does n't understand all that much at the best of times.

Electronics is fast and moving vehicles don't move all that rapidly. It's e asy to recharge your electric tooth brush when it's sitting on it's charger . A vehicle moving across an extended charging network needs a more complic ated charging system, but most of us are up to designing relatively complic ated electronics.

This LED faucet-light powered by the water stream is a clever idea:

The energy-scavenging self-sanitizing door handle with UV light emitter built-in, one of those things I totally thought of myself one afternoon a few months ago when the C-19 situation happened only to discover it'd already been invented.

That's how Daniel Moore died, you know. Disgruntled inventor shot him when the shooter discovered Moore had already patented something he was working on. The early history of electronics was pretty gangsta

Well, easier way is not to have door handle at all. Just motion sensors.

Actually, we are working on sanitizer for gas pump and charger handles, until there is a cheaper way to do hand-free.

Looks overdone and silly. Just making the handle out of copper, or even just copper-plating it, would make it naturally self- sanitizing.

Copper gets a patina, I don't think you get the effect if it's oxidized. If you clear-coat the copper same problem.

The oligodynamic effect of brass doorknobs takes hours and some infectious agents tend to be resistant. UV works in seconds, these handles look to be for high-traffic areas.

It's the copper ions that are the biocide, patina won't stop thatl; silver, same deal.

The low power 5G seems to scare people, just wondering how such high power magnetic system would scare people :-). Not to mention erasing any audio or digital magnetic media carried by the occupants.

Due to different separation from the ground different frequencies would be needed. If this is built along the road, there would need to be short (a few meters) sections operating on different frequencies, when different vehicles pass by.

There are only a few frequency bands allocated for ISM (Industrial, Scientific, Medical) frequencies, so only a few spot frequencies would be possible.

A better solution would be building a linear motor "stator" into the road and have "rotors" in each car. Each car would be moving with the same speed, thus keeping constant distance between cars. Car steering could also be connected to the linear motor, so long distance travel would be possible without active driving.

I was expecting a perpetual motion machine based on the headline. How boring - it is actually just another wireless charging technology.

It isn't entirely crazy but it would likely kill anyone with a pacemaker that was crossing the road or in the vehicle.

Doesn't sound remotely economic.

It will be fine after we have enough nuclear power plants to supply the energy needed for all the electric vehicles.

Interesting but only slightly related. 'Formula One' race engines, the are a 1.6 liter motor with 1000hp. about 700hp is from a highly developed ICE, the other 300hp is from two electric motors, that get their power from two sources, one regenerative braking, the other from exhaust gases, that is converted to electricity to charge a 20kg lithium battery. But with lots of nuances on how the motor/generators are put in action

I was thinking about the economics of installing and maintaining all that equipment in the roads.

Funded by DoD, which makes it fundamentally moronic. And any claims of scientific or engineering merit have no credibility whatsoever.

If it was funded by DoE then it would be a different story. Hydrogen fuel cell power for vehicles is the way of the future, not this garbage with rechargeables.

Twaddle. If you use hydrogen as a fuel, you get about 25% of the energy you used to create it out of water. If you use batteries, you get about 85% of energy you started off with..

Hydrogen only makes sense if you can't lay cables.

Conversion efficiencies are not an issue when the electrolysis is powered by renewable energy. Hydrogen power is the way of the future. That statemen t is not my opinion, it is the conclusion of extensive literature survey. Y ou will not be given any links or supportive argument to that effect.

Is this just the physics of breaking the hydrogen bond, or is it possible there is away to get the hydrogen from water without have to use so much energy?

What is the white mineral that when mixed with water releases hydrogen. The put it in canisters during WWll to fill signal balloons. Mikek

This is STANFORD! They rediscovered resonant coupling and took "years of tinkering" to get a switchmode amplifier to work. The PR department took maybe 45 seconds to publish.

fraction of the time it would take a car moving at 70 miles an hour to cross a four-foot charging zone. The only limiting factor, Fan said,

Fun, transferring 70 KWH in milliseconds.

Frederick Terman would never have allowed this level of stupid.

If you have X KWH of energy, from any source, you'd be crazy to use it at 25% efficiency. You'd sell at the market price.

Well, it's exactly what the nuclear power industry plans on doing. It's als o the new storage medium for overcapacity on solar farms, to power the peak ing generators.
