The alternative is the SLS, how many billions down the drain is that? The true issue with the launch was the flight termination system taking 15-30s to trigger, which they have had to requalify since that is what protects the public from ha

Sorry to break it to you, hydrogen or e-fuels definitely have a place in the future for fertilizer, seasonal storage and maritime shipping. For personal vehicles BEVs won nearly 10 years ago. See the "Hydrogen ladder" for further,

We are not? We are building renewables where the risks all come from the people working on the equipment. Fitting the analogy of airline safety nicely.

The point being, the "few hours" can be at any time from when the solar panels stop filling the outbound power grid connection, or a trickle all night if that is what the market needs.

Which is why the aviation industry is extremely careful. The limit for steel is like 80% for it to recover while for aluminum it is 20-30%. Not including micro cracks. Thus you need to carefully control the number of cycles, which the aviat

You can use compressed air. The COPV Spacex uses for tank pressurization are rated higher than the Titanic depth. And as depth increases the differential decreases. So you really only care about their structural integrity at the surface.

Given that nuclear on marginal price markets would require 5-8x the costs from renewables that is a win? Stop living in the 70s.
