That's a good point. Maybe not cool, but it would warm the water less.(I'm guessing solar cells reflect less energy back into space than water, since they're specifically designed not to.)
80% of earth's surface is still uninhabited. All of that (including the seabed) is vastly better suited to human settlement than Mars, and it's right here.There simply isn't a reason to settle Mars at scale right now.Once the oceans, the Sahara and Antarctica are full of overpopulated cities, we're growing our food in low earth orbit and are desalinating oceans for drinking water, it might look different.But I don't think we'll make it to that kind of population before we commit collective suicide.
Americans are trained from childhood to shit only once a week so it takes away less of their work time.This starts in school where you need a signed permit to go shit, and continues in the work place where shitting during work hours can get you in trouble.Shitting frequency is monitored through comically wide gaps in the bathroom stalls.
For a skeleton watch, yes.For a mechanical watch, also yes.Unfortunately, prices have gone through the roof in the past few years.Now I don't think there are any nice quality watches left in that price range.
You can still get a Vostok Amphibia for that kind of money, which is entirely hand-crafted, definitely interesting mechanically, and will last decades. But buying from Russia at the moment (on a Russian website), waiting a month for delivery, and getting the Vostok experience isn't everyone's cup of tea. Also, I don't think it's even possible to get them shipped to the US.
Even a nice Quartz watch like a solar-powered Citizen Eco-Drive will be slightly out of your budget.If you still do want a mechanical watch, look for Seiko, Citizen and Orient. Those are the best budget offerings.Chinese Red Star watches also fit the budget, but they're also not for everyone.
Unless you're China.
