Earth isn't even really a "rock", it's mostly a ball of iron. It's a ball of iron covered with rocks (i.e. metal oxides) cover with water (i.e. hydrogen oxide).

I would use Americium-241 instead, longer half life and much more availability. Lower power, but a telescope like this does not need constant power, so some kind of short term power storage (capacitor I would assume, or some kind of ultra l

Maybe when a train costs less than an airplane ticket. But right now the train costs more and takes longer. Why would I do that?

The gyroscopic effect of a hard drive is easily removed by having two identical ones attached together back-to-back. You would anyway want two for redundancy.

This is such a weird take. Have you ever actually lived in a such a place? Because your description is NOT what it's like to live there. Suburbs designed around cul-de-sacs are amazing to get around in, very very easy, extremely bike

Technically: Yes. A modern natural gas stove would be more efficient. Practically: No. It's just not enough emissions to worry about.

At some point the element will decay faster than it can exist. There are already subatomic particles that get created on one side of the particle and decay on the other, i.e. their lifetime is shorter than that time it takes for light to tr

It's clicbait for making it seem as if Telsa is somehow unique in being down, and they go on an entire sidebar/tirade about it. But actually there's nothing different about Telsa vs the other car manufacturers. They should re

This is a stupid article, it's hyper focused on Telsa for no reason at all. Look at the image at the top of article, and ignore the rest.

Microprocessors with tiny features are a chokepoint, but I suspect you could make a primitive one if you really worked at it, i.e. go back to 1960's technology, such as the AL1 or 4004. Even going to 1925 and teaching how to make a MOS

We'll be fine. We'll have to make adjustments, but we'll be fine. So will the planet, and so will the vast majority of animals.

It mostly ends up in landfill. At some point we may be resource poor, and but energy rich and we'll use Plasma mass separation to separate each element out and reuse the valuable ones. Until then it's safely stored there.

Would sterile neutrinos as an oscillation really change anything about dark matter? The total mass of neutrinos doesn't change, just the lepton number.
