1800 kJ > 100 kJ Even if they achieve 'burning plasma', it's still like a 100hp engine using an 1800hp spark plug.

You don't strictly need one. There are designs that rely on exhaust pulse resonance for pressure. There are designs that use various kinds of mechanical valves. It looks like (propane fuel) tesla valve pulse jets have been built, but I

It's on the internet forever now. If there's a balance to strike it would have had to have been done in 2007 when the court digitized their records and put them online. A search for "minor consuming" reveals a few hundre

>It would still require moving parts though (unless it's only used as a ramjet), since a jet engine has to compress the air before heating it. You could use a tesla valve for an electric pulse jet, that would make for no moving part

You can't really get away with just knowing del from vector calculus, as this is the geometric-calculus del. ∇F = ∇ . F + ∇ /\ F But for defining the terms you're going to need a couple paragraphs to go along with the on

I expect it would be much harder to put a mirror factory in orbit than a mirror.

Not especially, but certainly more money than I would light on fire. That would actually be an even more abstract extensions of the self though, incorporating the bike by way of my finances.

When my bicycle is subjected to hard bump, even if no part of my body experienced much acceleration, I'll make the same sort of sharp inhale I do if my elbow is subjected to a hard bump. You really do develop the sensation of feeling

A part can have features much smaller than it's total size. One way to think of it is, a part is nanoscale if you would choose nanometers as the length unit on the drawing.

Quibi seemed to do a lot wrong. But when it comes to how bad their content was, I've seen some writers say Quibi produced first draft scripts other studios had passed on without a re-write. They thought they could run with proof-of-con

Powering those ion thrusters is a bit of a problem at the mass ranges you need for peopled interplanetary flight. Either you have an absolutely enormous solar array, or an absolutely enormous radiator array for your nuclear reactor.

I think he says early on that the archive trap doesn't have self-awareness, except for a few subroutines that need to be self-aware like the simulations of the researchers which facilitate the escape. Even the name blight evokes a fung
