And Uranium-235 about 1GWh/kg EDIT: this is for nuclear fuel enriched to 3% in a normal (not breeder) reactor 35000 MJ per 10g pellet https://whatisnuclear.com

- ly3xqhl8g9 4y agoUranium-235 is around 24 GWh/kg [1] (24,000,000,000 Wh). [1] https://www.euronuclear.org/glossary/fuel-comparison/ https://www.euronuclear.org/glossary/fuel-comparison/
- travisporter 4y agoWhoa so… 100kwh is 40mg! 3grains of sand to run a Tesla https://www.wolframalpha.com/input?i=100kwh%2F%282.5+gwh%2Fkg%29 https://www.wolframalpha.com/input?i=100kwh%2F%282.5+gwh%2Fk...
- m3kw9 4y agoExcept a lot more is released at once so it will accelerate like a jet engine on every stop sign
- travisporter 4y agoHaha yes I did not think about that. There’s no throttling there
- the_duke 4y agoYou need to account for all the weight required to turn the radiation into electricity. That'll make the numbers ... a bit different.

- philipkglass 4y agoThe GPHS RTG contains 7.8 kilograms of plutonium 238 but masses 57 kg in total. It also generates only 300 watts from that 57 kg package: https://en.wikipedia.org/wiki/GPHS-RTG https://en.wikipedia.org/wiki/GPHS-RTG You'd need about 3 metric tons of them to power one Model 3 cruising at highway speed (assuming ~16 kilowatts continuous power draw).
- stephen_g 4y agoNot to mention that you have to mine and refine a couple of tonnes of ore for every kilogram of refined uranium.
