A top to bottom look at green energy
I struggled with deciding in which forum to start this discussion. It could be germane to a lot of them. But since the Tesla thread has had so much activity, and Tesla's technology is central in the c...

Nano-diamond self-charging batteries could disrupt energy as we know it
Still highly debatable...and again “pre-embryonic”, but that is where most great break through comes from...just an idea...
The German’s or another European inventor helped reduce the rubber tires in landfill/oceans/etc by grinding up old tires and use that in the asphalt mixture for paved roads.
Extended the useful life of asphalt roads by having a higher elastic material so the pavement wouldn’t crack as easily. Coefficient of friction was also good.
Down side, it still has decomposing tire dust to deal with. There is a bacteria that consumes the tire road dust...few know of this

California company NDB says its nano-diamond batteries will absolutely upend the energy equation, acting like tiny nuclear generators.
They will blow any energy density comparison out of the water, lasting anywhere from a decade to 28,000 years without ever needing a charge.
They will offer higher power density than lithium-ion.
They will be nigh-on indestructible and totally safe in an electric car crash.
And in some applications, like electric cars, they stand to be considerably cheaper than current lithium-ion packs despite their huge advantages.

Let me clear up your understanding of radioactive half life. Did you know that bananas contain a good amount of radioactive potassium 40? But you can safely eat bananas. If you ate the same amount of Cobalt 60 in your hand it would kill you. Both radioactive so what is the difference. K-40 has a half life of 1,250,000,000 years, Co-60 has a half life of 5.6 years (IIRC). One is death, the other not. The shorter the half life the more dangerous a material is, generally.
This is why the radioactive waste will kill people a hundred thousand years from now is mostly BS. Reactor waste is a mix of elements. Some with a very short half life and thus very dangerous. For example Ba-139 is present in that waste and it has a half life of 83 minutes. A speck od Ba-139 would kill you right there. But you can generally assume that almost all of an isotope is gone in 5 half life's. Meaning that in 8 hours that Ba 139 is gone. The dangerous short half live stuff is gone in 100 years. !000 years from now you half long half life material that isn't that hazardous and 10,000 years from now you can figure what is left. Stuff with a half life longer than 2000 years.No as to your carbon enclosed hot stuff, it would not do a thing for a gram of Ba 139, it would still kill you right there. For a gram of Th-230 you would be fine, it has a HA of 75000 years. But you's get very little energy from it.
