Politicians don’t need to know the details, they need to be advised by competent people with the best interests of the public in mind. Which may sound straightforward while being really difficult to get right.

The space shuttle’s design was also deeply flawed to the point it failed to do the core objective, significantly lowering costs. Instead the core mission was sacrificed to meet some arbitrary design goals such as being able to de-orbit hea

People do make it work in the US with tiny incomes and a better standard of living than you’d see in a typical 1960’s household. I know people raising a family of 4 on 1 income well below the median wage without a collage degree. They do g

Thanks, I misunderstood your point. Sure Elixir is fine to work with, the thing is in the back of my mind I’m thinking it’s way more likely to end up embedding Python libraries in Elixir code than the reverse. It’s those little bits of fri

You can do a similar Python REPL. So I’m really unsure what you mean here? I mean it’s a little better for displaying data structures but I never really found that particularly useful.

Between Python and Elixir or Golang, I’ll stick with Python for an exploratory side project. It’s just a better fit when you’re not quite sure what you’re building. You just gain more on the 99% of projects that never go anywhere than you

10 TW * 1 year = 8,760 TWh / year. The current rate of energy production is ~42TW and slowly dropping over billions of years, so even after efficiency losses gathering 1% of what’s produced is several times current energy consumption.

Not really how that works. Also earths core is being heated from nuclear decay and tidal effects. It’s getting 10’s or TW worth of heat until the sun expands and eats the earth. https://en.wikipedia.org/wiki/Earth'

That’s overly simplified, and these lakes normally only fully mix every few years. In winter surface water is colder than sub surface water so if you start pumping water to create a cold and more dense column of water in a pipe you can stop

I agree learning should happen, but you don’t learn to drive a car by someone handing you the keys on day 1. Learning just about anything looks very different than handling the full responsibility of doing the thing correctly in your own.

The drinking age is 21 in the US 18 is not quite full adulthood, so 12 is still quite young. Even just 1 year is a big deal for kids, 6 years is a huge jump look at 0 vs 6 vs 12 vs 18 and these are very different people. You see my last se

If you own water rights, selling them to a city at near desalination rates is way more profitable than farming. So desalination only makes economic sense after removing all farms from an area.

The drone’s goal is to locate it, you’d then send something else to destroy it if you’re in an actual war. America uses surface buoy’s to similar effect, going underwater would allow drones to be harder to detect. https://idstch.

Storage is cheaper than peaking power which is why it’s common to add huge battery bank to solar power plants. It’s simply more profitable to add storage. Net result renewables currently save you money until ~80% annual electricity supply.
