Ro vs distilation isn’t nearly as clear cut as it appears. Well designed distillation systems recover most of the heat warming the incomming water (cooling the out water). Ro pumps use more energy than you expect at scale. I’m not going to say one is better but don’t discount either without a full analisys of your situation.

Computers don’t produce heat high enough to be useful. You want the output temperature the computer cooling to feel like a warm room. That isn’t hot enough to boil water. It isn’t enough hot enough to do anything useful with.

Detroit is not cold in summer. And places that are cold year round are running into issues from global warming and permafrost (I don’t understand the issue, but they exist) without adding local heat.

Sorry, I got lost in my reply. Electric brakes done well are not noticed. Surge brakes you can feel the trailer push against the truck before they kick in, and oscillate - it isn’t much but you feel it. Surge brakes mean you cannot back up - the trailer brakes turn on when you are in reverse.

Electric brakes also meant that when the brakes failed on my truck went out I was able to stop safely and limp to a place where I was able to get a repair done. This is kind of a niche, but still one I’m glad I had.

Those “surge brakes” suck. They suck on a car, and they will be even worse on a bike. There is a reason most trailers have electric brakes and require the towing car to tell it how much brake force to use - it works much better. (air brakes might be even more common for trailers, but that only applies to large semis - I don’t know enough about air brakes to comment but they need to be acknowledged) The only advantage of surge brakes is you don’t have to ask if the towing vehicle had the right controls to support them, which is why rental trailers mostly have them. However for every other purpose electric brakes are better.

There are a lot of brain injuries to cyclists that while not fatal are still harmful to a nice life. Helmets help again them. There is nothing you can do if you are hit by a car, but there are a lot of accidents where you are not hit by a car that you will survive, but it will affect your life.
