I wonder if we had the capability to use black holes for energy would our deep reservoirs of garbage be a good source of energy.
Based on my Google research black holes get 40% of the mass energy of the object. We have hundreds of tons of garbage in oceans and landfills and burning it isn't an eco friendly solution.
Micro plastics will likely kill us before AI or climate change does. This has to get fixed or there's just no species.
Black hole feedstock would likely be either a stream of hydrogen or iron dust so you can control the rate of emissions like a combustion engine. If you know how much comes in at which point you can know how much comes out when.
We're trying to do civil engineering here so you want something with a known composition and flexibly adjustable flow rate.
