And this is the bullshit part. Inductive charging? Sure. Wireless power transmission, even? Sure. For static objects.
I’m going to completely disregard the unholy engineering nightmare that is “creating a power receptacle capable of outputting constant current when provided with a perpetually and violently changing intensity of current as input” and focus entirely on the input itself. The inverse square law means that allowing a receiver to be at an arbitrary and ever-changing distance (such as a moving vehicle) requires a transmission source that puts out an absolute goddamned fuckton of power to ensure that, at said arbitrary distance, the target can still receive whatever the minimum power it needs to operate. So that’s just untenable.
And even then that’s not taking into consideration what that minimum power would have to be to push a car and its cargo while “remaining charged.”
It doesn't necessarily have to be constant or consistent voltage. There are hand cranks for charging phones. That's hardly consistent but it still works. Guys in prison nigger rig chargers out of just about anything with a current.
As long as it can make a needle jump that power can be stored. And there wouldn't be a single transmission source. You are bathed in radio waves everywhere you go. Cell towers, 3G, 4G, 5G, wifi, radio, television, & satellite. All of which take power to produce, and thus logically contain some power that can be captured.
Again, nothing about that idea sounds fundamentally implausible except maybe the amount of power you can capture relative to what it takes to charge a car battery.
The claim isn't free energy.... It's "free to me" energy.
There’s hardware in the device to convert the variable voltage of the cranking into a smoothed voltage in order to send it to the battery without the battery exploding. That’s my point; the hardware required to do this WIRELESSLY for a VEHICLE IN MOTION doesn’t exist.
Oh boy, seven month charging times for 300 mile range!
That part doesn't have to be done wirelessly. Just capturing the energy. Everything else can be hard wired on the vehicle.
And I think exploding batteries might be a risk with overvoltage, but I don't think it would be with tiny amounts of energy you'd get from radio waves.
I mean hypothetically if we have a proof of concept that it's at least possible to covert radio wave to electricity, you could make the car's entire body a surface that absorbs the energy.
Then it might be enough to at least use that as a hybrid source of energy, supplementing plugging into the grid.
It… does. Otherwise the vehicle can’t "power itself from radio waves.” The receiver has to be in the car.
Correct, but with the scale of power output required to actually do what the post claims it can do, it would be on the order of what happens to commercial windmills when they don’t shut down in high winds.
Remember in the ‘80s when “microwave power stations in orbit beamed down to Earth” was The Future™? Turns out, with the surface area required by the receiver antenna, solar panels (even at the time) could produce about three times the power. It’s just not viable. There are some electric cars today with solar panel roofs (to do just what you’re suggesting), but even then it’s really, truly just a “top up” supplement, not anywhere near capable of powering it indefinitely.
