Thank you for the math. But I don’t think you really tried to understand my point. Firstly, the newest solid state batteries (relevant because that is what I was responding about) are 2x the density so that is quite good (8.5x/6.5x). Which is already pretty close. They are also going to get better through iteration likely to 3-5x or so (but let’s ignore that for now). Secondly, the power train also includes regenerative breaking, reduced weight from transmission, in hub motors (reducing axcel weight), reduced center of gravity allowing better drag profiles, no external coolant systems, no engine oil compartments, no fan belts, etc. I’m happy for you to keep doing the math, but the reality is XXX km or miles per “full tank” is the best measurement because it takes all those factors into consideration.

Oh I'm not so against EV, I'm just being pro-nuke as I personally always has been. Honestly I don't get why some sort of EV supremacy theory has to be defended at all costs. Those are just facts that density and recyclability of Li-ion is just atrocious. Gasoline particles tho NOx bad for health yeah I get that part. Seriously, if we could just build 2-3 air-cooled Plutonium fission per each megalopolis core and use e-Fuel on existing hybrids we'd solve everything in modern society ever. The reactor could double as cityscale thermojet ventilation system as well, eliminating heat and atmosphere problems once and for all. It will of course work as a training exercise for coming real Space Age in which humanity builds bunches after bunches of cylindrical habitats fabricated and populated in space. The only two roadblocks towards that path are some NIMBYism/NPT fears and cost.

  Fair enough! I’m just on board with the electric ground transportation thing. I’m very happy for there to be really nice and safe fission reactors everywhere for grid scale generation. Including efuel generators for air and space transportation.

If you dont like him doing the math why do you bring up the thermodynamic efficiency instead of the max range? It sounds like you just like math tidbits that make EVs sound better than they are. And dislike math that shows gasoline is superior from a purely practical standpoint (its far worse environmently)
