100uW from a nuke. :D I can get 6uW stealing 5G power. o_O

Antenna sub-arrays, rectifiers and DC combiners are then added to the structure to demonstrate its combination of large angular coverage and turn-on sensitivity—in both planar and bent conditions—and a harvesting ability up to a distance of 2.83 m in its current configuration and exceeding 180 m using state-of-the-art rectifiers enabling the harvesting of several μW of DC power (around 6 μW at 180 m with 75 dBm EIRP).

Actually a nuclear battery is not that far fetched. I remember reading about this. The Perseverance rover requires electrical power to operate. About 110 watts at launch, declining a few percent per year and it weighs in at about 100 Lbs. Hate to see the cost but it really isn't anything new. Some of what I am seeing in my lifetime was Jules Verne stuff when I was a kid. Seeing some pretty cool stuff during my lifetime and pretty much an E ticket ride.

It’s not nuclear batteries per se that are silly, it’s this one in particular. There are various sorts of nuclear batteries powering pacemakers, spacecraft, and other things where changing them is very hard or impossible. There are betavoltaic batteries that use something like photovoltaics to generate small, very expensive power for those with unlimited budgets.

But this thing is pure hype, it’s an investment scam.

Oh as to this thing, I agree it's pure hype.
