This five-cell metamaterial array developed at Duke University has a power-harvesting efficiency of 36.8 percen -- comparable to a solar cell. Credit: Duke University

Very cool. I also wonder if you ‘turned up the heat’ if this could somehow be used to be a EM dampener for avoiding detection.

They used a series of five fiberglass and copper energy conductors wired together on a circuit board to convert microwaves into 7.3V of electrical energy. That's nice.
How many watts?

I was thinking it could be used to power bugs - listening devices - anywhere the CIA or whoever would want to use them..............

With today’s microelectronics, one must think in terms of microwatts...............

Thanks, good point.
You can have all the volts in the world and they won’t power a cell phone without some amps.

But can you charge an RV battery with it?

Incremental is right. This might have some limited uses but it is nothing like solar panels that capture the energy of the sun that is out out for free. There is no large free source of microwaves to harvest for serious electricity generation.. But I could see this possibly recharging a cell phone ...somewhat

But can you charge an RV battery with it? If you drive around areas with lots of WiFi hotspots maybe.
To: Red Badger
Hmmmm..I could bake a potato in my microwave and recharge my cell phone at the same time.

I’ve found that most PR hype out of universities corresponds with getting the alumni all fired-up for a big fund-raising campaign.

It was given to Ambassador W. Averell Harriman by "Soviet schoolchildren" in 1945 as a gesture of friendship in the wake of WW2. The bug concealed within remained in place until it was discovered in 1952, during Ambassador George Kennan's tenure.
