    The Navy does a lot of this. They funded a program to make biofuels from algae. But don't forget that the stated purpose of funded research is often a lie[0] and this is not necess…

    Few though, and only the largest ones and they have incredibly complicated and long (and dangerous - imagine having to deal with refueling a cyrogenic liquid after every leg) fueli…

    Its so bad that only the largest space rockets use liquid H2. All the others use kerosene or the like. Either way, the Soviets tried gaseous fuels in the 80s - See Tu-155. They ran…

    I'm not in this field (university friends are), but reactors require triple redundancy for their power supply, including the grid. A better question is, should we have nuclear powe…

    It's sovereign immunity. Any state agency can do whatever it wants and claim immunity unless the Feds get involved. The Feds can do whatever they want full stop. The only constrain…
