So you agree with my point that it's not a purely defensive alliance?

Stating things like "NATO is a purely defensive alliance" makes me question the accuracy of this analysis. https://en.wikipedia.org/wiki/NATO_bombing_of_Yugoslavia

The Moon has very little hydrogen, carbon and nitrogen, which Mars has in abundance. These are very important elements both for biology and chemistry. E.g. if you want to have a self-sufficient colony outside Earth, you could do it on Mars

In perspective, you should keep in mind that the Space Shuttle was a failure as a launch vehicle, both in terms of safety and economics.

Because I'm down the rabbit hole of highly customized keyboards, at one point I did a frequency analysis of the keys I use the most. Guess what was the most frequently used key? Cursor down followed by cursor up. For example, cursor do

I've had more than one YKK zipper fail on very expensive technical jackets. Not sure if I was just unlucky, or your statement is wrong.

Hydrogen is bound in both compounds - you need to expand energy to extract it. As in our oxidizing atmosphere natural gas is a source of (chemical) energy, you can burn it to provide the energy needed to extract the hydrogen. This is the st

But the D-D -> He3 reaction produces a neutron. So the whole approach could hardly be called aneutronic?

Where do they plan on getting the He3 fuel?

Current reactors (light and heavy water reactors) all use solid fuel, which is very inefficient due to use of once-through fuel cycle. Because xenon is the most common fission product, and it's a gas, the reaction must be stopped befor

You don't have to imagine, simply put a spoon sideways against a flow of water from the faucet and you can instantly feel a pull.

The wing doesn't need to be shaped a special way to produce lift. In fact, a flat board can produce lift. The special shape is just an optimization, ie. cambered wings are more efficient/stall at higher angles of attack.

Plant production is also heavily subsidized in the US [1], so I don't see how this is relevant. [1] Soybean Subsidies in the United States totaled $44.9 billion from 1995-2020 - https://farm.ewg.org/progdetail.php?fips=

There are already good references in previous threads (e.g. look up anything by Gabe Brown). But in a nutshell - plants are in a symbiosis with the microorganisms and fungi that live in the ground. Plants feed them sugars and they feed the

Yup, I did this and it's great. I also ended up assigning the thumb key to 0, since I've noticed it's used more often than other digits (and also you have to fit it somewhere, since the other ones are in a 3x3 grid).

Since you're already planning on using hydrogen fuel cells for propulsion, does it play well with using hydrogen as the lift gas, too? Since the airship is unmanned, this seems like a good synergy.

Taxes are a bit complicated in Switzerland. While they are nominally low, you pay separately for things that are covered by taxes in most other countries. One example would be health insurance. So while you'll definitely be paying less

This technique is not new. E.g. I remember it described in ARM system developer's guide published back in 2004. It shows how to use unsigned 64-bit multiplication to restrict a range of a 32-bit random number generator to 0..N. No shif

"In Python and many others, in general, there's only one kind of number, and that's the double-precision floating-point." I don't think that's correct for Python!

Yes, but that's not an issue here. Life support would require a lot of electrical energy, not heat.

Well it did improve the manufacturer's bottom line.

Of course, as long as you're not burning carbon. I believe heat pollution would only become an issue once we start using several orders of magnitude more energy than we do now.

Energy released as heat to the environment is currently a rounding error compared to heat trapped due to CO2 emissions.

Just somewhat related, I have both an inkjet printer and a 3D one, and came to a realization that it should be very easy to combine both in the same device. I would buy it just for the space savings, never mind the $$ saved.

Anecdotally no. I'm not sure if it's the ink formulation, or just that when the ink is so cheap you print much more often so the ink doesn't dry up.
