It is. But I doubt they are used by 3 combined people.
The Debian project needs to keep the machines for compiling and testing. And there's probably no other machine of those architectures available for the enthusiasts to actually use.
It's doubtful if most of the reserves can become viable at any price. (Because the cost of materials increase when oil price increase.) But some are perfectly viable.
But also, even in perfect conditions, if they started drilling right now (what they aren't), it will take several month to start getting any of it.
You can push electrons into a capacitor if you don't connect the other side. A few of them, but more than zero.
There are electrostatic generators that work by pushing electrons on one side and pulling from the other of some insulator that moves between those two. But you can't sustain a steady state of only one of those actions.
On the case of the real drone, the laser is destroying the cable.
On the OP's case, yes a laser can interrupt the communication. But the drone needs to keep sending it, or the drone will just continue after it's gone. On the other hand, you need less power.
Just to point to the people that weren't there yet, the US made a lot of noise on the press every time they "found" some of the chemical weapons they sold to Iraq in the 80s that were stored in UN-approved deposits because Iraq had no means of destroying them.
