Re: Could we ever replace fossil fuels in aviation?

Of course we can. Already for short flights, you could power regional air transports with the 250 Whr/kg batteries we have now. Longer flights can use methane which can be synthesized or ammonia which is also easy to synthesize. Both are likely more practical than hydrogen. And of course you can mak...

Re: "Physicists" discussion (#793)

Add me to the list of physicists who are guilty as charged. I had a run-in with a linguist who was just as smug as I was. I think he won. Still, though, this method of solving problems is pretty powerful if you come upon a phenomenon that doesn't already have a discipline devoted to studying it. In ...
