Nothing like a good moot.
Seriously, I dunno the health implications of having such a system. Thats alot of energy flying around.

Considering probably 90% of the energy sent out by the system will just float up into the ozone, I wonder if they will earn the "Energy Star" label?

There is also the uncomfortable reality that even with today's high copper prices, wires are dirt cheap and nearly 100% efficient.

My suspicion is that this will never be workable with a consumer product like a laptop. Maybe they can use it to power things like lunar rovers, etc., but if you can use the sun anyway, I'm not sure what the advantage is.

The problems are efficiency of the transfer, i.e. how much power is simply lost in the transmission, and the safety concerns with beaming that amnount of power around. You don't want people to feel like they're in a microwave oven.

They say the challenge is finding a 'magic' frequency that does not also affect living organisms and thus pose possible health risks. Hey, piece of cake.

Some folks, not all, mind you, are probably not gonna be happy about setting their laptop on their lap and having this gizmo focusing microwaves in that direction!!!

Someday we might catch up to Tesla.

the transfer of light energy from the Sun..involve relatively low levels of energy Well....OK then.

No fair. The original inventor of the cordless extension cord was Stephen Wright.

We're already swimming in multiple energy fields now (microwave, tv and radio signals, cells, radio transmissions, etc.) Sometimes I wonder what the cumulative effect all that radiated energy has on the human body.

He's using the non-electromagnetic part of the electromagnetic spectrum. :)
Non-radiative my tail. But, this could be due to bad reporting. This may be using a capacitance field approach that transfers data and thus energy via the surface capacitance of objects. A network technology was based on this.. Auranet, which played on the name of the shimmer surrounding people viewed in the morning light.
However, I still don't know what the effects of trying to transfer alot of energy via this would be.
I know it can be done. Did something like this for High School Science project.

Now that I think about it further, maybe it would be of use in a lunar rover. The problem with solar is that you've gotta drag those solar panels around with you. Maybe the receivers for this thing would be lighter and more compact.
To: Petronski
The electric toothbrush recharges just fine using magnetic energy to transfer the power.
Of course, its low power and less efficient than a copper wire - its basically a transformer with the primary in the toothbrush holder and secondary in the toothbrush. Perhaps this technology could be expanded upon...
