Few waste to energy plants work well and are very expensive. Plastic in garbage would mostly melt to globules which could be floated off from the hydrochar. This stuff works all right https://electratherm.com/products/ and is just a screw compressor. Note the aircon that generates electricity on the side.

You may be fascinated to know that a long half life means that the compound in question is rather safe. You know that all the nuclear waste in the US could fit on a football field right?

If one spent fuel assembly ever was mistakenly raised out of the water for a few seconds, and I was in the same room...I won't say more. You'd be okay if it were a few seconds. Everybody (not saying you) seems to think that HBO's Chernobyl has accurate depiction of radioactive health effects. It's pretty absurd. Hell, I found out a while back that swimming in a spent fuel pool would be just fine so long as you weren't in for too long. 1 Quote Share this post Link to post Share on other sites

The dose received from an unshielded, freshly removed fuel bundle (lifted out of the water) is REALLY high. An inch or two of water makes a great shield, however. Of course you can swim in it. Divers go in frequently to service "things". Be careful. Stay a few inches away from the spent bundles. If you ever attempt an unauthorized "swim" in a spent fuel pool, I can guarantee you will die... ...from gunshots.

I'll have to look into what would happen if I stared at an exposed core for more than ten seconds. Maybe it wouldn't be very peachy. 1 Quote Share this post Link to post Share on other sites

An actual breeder reactor which makes recycled MOX fuel/"undepletes" the DU is also very handy for making plutonium. So, they are not selling it. Fission nukes are so last century though.

Catalytic liquefaction was used to hydrogenate coal using high pressure hydrogen. The catalyst was some form of iron oxide,as is being used in the Chinese coal liquefaction plant.

You have 24000 years of tons of radiaoactive material to maintian and SECURE. Second as your spent fuel continues neutron alpha and beta decay you still contibute to thermal decay causing global warming. Rosatom is taking back all the spent fuel from the new reactors it ships. For reprocessing into new fuel. Quote Share this post Link to post Share on other sites

As far as I can tell, when reviewing patents, is that yes, ZERO work is being done by the US patent office at all. Leaving EVERYTHING up to the patentee in question to 1) ascertain if their idea is patentable and 2) protect their patent in court as the USPTO is doing shit all nothing from my perspective as a bureaucrat might have to make a distinction/decision and gosh golly gee, that might get their ass fired from their plush do nothing highest paid government job!

I have demonstrated this to you, ICE car sales are down and EV sales are up. You are being very funny again, just like your wild claims about the percentage of energy supplied by fossil fuels (which is 84%, not 79% as you claimed)...demand for ICE vehicles is very strong, mostly in SUVs which have a huge appetite for gasoline, and EVs are a tiny fraction of a fraction of total vehicles on the road. That continues going forward. If EV production attempts to ramp up, the prices of essential battery inputs will skyrocket, and so will EV prices.
