“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.

Better than plastic explosives and shrapnel.

I wonder how they did it. Was the firmware hacked to make the batteries ignite or were separate explosives implanted in each pager?

We need hydrogen production because we need emissions free steel, fertilizer, and vehicle fuel. It’s also a good way to soak up excess electricity production. Sure, batteries can store energy arguably more efficiently, but they offer no practical benefits beyond that.

I think you are correct that it’s the car’s fault. I have an MPOW brand Bluetooth adapter that almost always works properly with my phone. I use it in my Mazda 3 that doesn’t have Bluetooth built in. My 2017 VW Golf (one year older than the MPOW adapter) does have Bluetooth and it frequently gives me trouble. However, I’m typically able to get the connection to work by disabling then reenabling Bluetooth on my smartphone. Resetting the VW head unit typically doesn’t help, which is the opposite of what I’d expect if the problem was with the car. The VW has Android Auto over USB, which I thought would be the end of my Bluetooth woes, but that has enough of its own problems that I just keep putting up with the Bluetooth.

How about a version that successfully connects to my car’s sound system right away, every time?

Okay, district heating with a heat pump makes more sense to me if there are processes that require cooling and can act as the source, like lowering the temperature of treated wastewater before adding it back to a waterway. However, the heat supply for the water treatment plant should still probably come from cogeneration. District cooling with a central heat pump system also makes sense, especially if it eliminates noisy condensers on the sides of buildings.

What about when you don’t have excess solar power? People need heat when they need heat, not just on sunny days. So, you’d need a massive battery for that, which has some undesirable implications. Instead, a thermal plant (be it solar, geothermal, or nuclear) can be designed to reliably satisfy heating and electricity demand with excess electricity going to hydrogen production for emissions-free steel, fertilizer, and vehicle fuel.

Nothing wrong with putting nuclear power plant next to where people live and work. They produce good steam for residential and industrial uses.
