When the aluminium oxide is bombarded with microwaves generated from the same sort of device that powers a microwave oven, a concentrated electric field is created inside the void.

Don't those type of devices themselves use a lot of energy? I wonder if they are factoring in the energy that device uses when comparing the cose effectiveness of the lamp?

What is the “cose effectiveness of the lamp?”

hmm, i’m sure they are greatly scaled down since all they have to do is get a couple lights going vs defrost 5 pounds of frozen spaghetti sauce, but I would def like to see how they set this up. I love reading about new techs and it def looks like these guys were thinking outside of the box on this one.

Evidently not necessarily. It's not like you're trying to locate a SU-27 at 150 miles...
For example, the microwave oven, quietly going about its business, is never given credit for its monumental savings in energy use compared to traditional means of heating and cooking foods.

On the really, really good side, I might finally see something I have been hoping for for years: the mug-sized microwave oven for re-heating coffee...

Where do think the other 50% went?
