“Ars on your side!”

Why can’t it stay liquid?

Well, the water is necessary for for life support and needs to be sourced somehow anyway. It kind of sets a minimum crew and passenger capacity if you want to make the most use of your shielding water.

Water doesn’t have to be a liquid, but don’t actual spacecraft typically contain liquids during wall of those cases? What do you mean?

I don’t think it works that way. The water slows down the neutrons so that when and if they get to you they don’t have enough energy to hurt you. The radiation doesn’t contaminate the water any more than a microwave oven does.

Since the astronauts need water to survive, why not line the spaceship with reservoirs of it to provide the shielding? Or does water not block space radiation well enough?

Trying again doesn’t necessarily mean trying again right away.

They could have tried again with another booster and landing pad.

If the developers could fix search, it would go a long way in improving Mastodon.

Never post your resume or sign up for LinkedIn in the course of a job search? Never use a dating site? Never buy a domain? Never pay property taxes? Never go to court? I see your point, but never revealing your info online isn’t realistic or even a choice for most people.

Or a brand new set of DNA altering forever chemicals.

Is this really still true about images federating in Lemmy? In any case, I think the problem can be avoided by disabling pict-rs.

They don’t have to sell hydrogen or solar panels. They’ll just keep selling fuel to power plants.

That’s a lot of future e-waste to lug around just for cooking.

Their days aren’t numbered until governments actually say so. In the meantime, non-GHG emitting sources supply less than half of the world’s electricity as is, nevermind the hypothetical demand of a predominantly electrified vehicle fleet.

Unfired pressure vessels are already pretty common common in industrial, commercial, healthcare, transport, and recreational settings. I am comfortable with continuing to trust the engineers as the portion of these vessels that contain hydrogen increases.

Fossil fuels, including coal, are also used to produce electricity. They simply need to be prohibited or at least strictly rationed. Fortunately, hydrogen can be produced without emitting greenhouse gasses because it is still necessary for processes like steel and fertilizer production. It’s also a practical replacement for fossil fuels in transportation and, as Toyota demonstrated, food preparation. As I replied to someone else, sometimes we need portability and/or a flame when it comes to cooking. Electricity just doesn’t cut it in those cases.

If these are serious concerns for you, I’m sure you will always be able to find plug in electric grills on the market.

What’s so exotic about a composite pressure vessel? They’re already used in scuba and paintball.

Compress it to 10,000psi and it gets portable enough.
