We could embrace nuclear power and massively decarbonize the economy, but ... well, the enviros think a nuclear waste repository is too risky. Better to undertake global experiments in geoengineering, because they have confidence their models are always right.
How long will these chemicals persist in the atmosphere? If they wash out in a few days, we might be able to monitor changes in reflectivity via satellite with the assurance that the effect is fairly localized and of short duration. If the chemicals are persistent, it’s a different ballgame.
Me? I’m for a nuclear waste repository.
I'm for nuclear "waste" reprocessing.
Recycling is a "Good Thing", right?
“I’m for a nuclear waste repository.”
Filled with real nuclear waste as in just the glassified fission products that make up 4% of spent fuel the other 96% is still fuel once you remove those neutron grabbing fission products. Bonus is all but two of the fission products has half lives under 1000 years most in the decades level so after 6 half lives they are under natural uranium levels again. Pack those borasilica glass cylinders into deep boreholes drilled two miles deep in geological time frame stable granite there is a billion year old spot in central Texas. Fill the bottom mile with glass cylinders packed in bentonite clay mud and concrete the casing strings up to the surface you now have forever entombed those fission products. Nuclear waste is a political problem not a technical one. With reprocessing spend fuel becomes new fuel and glass entombed real waste.
I propose that the government buy me five sections of land directly over the llano granite pluton. I will offer my services as a geologist to drill the boreholes down to 12000 feet TVD spaced 50 feet apart in a grid pattern. Then drop the stainless steel clad solid glass cylinders down the holes while displacing bentonite mud. We will then fill the case strings and outer case space with concrete from a depth of 6000 feet to the surface. For my drilling expertise I will require the land for free in perpetuity for my families exclusive use, $1 million per annum indexed to inflation also in perpetuity for my families to “monitor” the surface hole locations. I personally will live on the five sections of land and any of my lineage may also choose to live on it property tax free while only using water sourced from rain capture or ground water this should stay any fears about ground water contamination which would be impossible with impervious glass,stainless steel,bentonite mud, case steel,concrete and more case steel plus yet more concrete. I will live out the rest of my days ranching in tax free peace happy as a clam all that waste two miles below my feet.
