Selling used equipment? Only used item to sell is Bridges. I have several Tom, if you want to man you own toll booth. (Weak attempt at a joke!)

Re: SpaceX News

Just googled "length of falcon 9 first stage" and got 47.7 meters with interstage. That's ~156.5 feet.

Re: EMC2 news

I second that. NEVER let yourself believe that the simulation is reality. They are much more helpful after experiments, used to discover where the current understanding of reality is amiss.

Re: SpaceX News

Does anyone suppose that the techniques developed for the return of the fairing would have any carry-over to the return of the second stage?

Re: Bill Gates is heading a $1 billion venture fund to combat climate change

It seems to me that almost everyone misses the point on global warming. The point is not so much that warming is happening, its the question of what is causing the warming? Is it people and our activities as is claimed - or is it partly or mostly a natural cycle that would be happening even if there...

Re: SpaceX News

Fun thing will be when the rockets start taking off, refueling while in space, then landing with enough to take off again, making the ground the stop off point, not space. Never happen with chemical fuel. The delta V to come down from orbit would be the same as the delta V needed to reach orbit so ...

Re: Hyperloop Technologies

Since we're talking about emergency pressurization scenarios, what happens if a car is speeding along and an earth quake or some other disaster rips the tube completely apart some few miles ahead of the car? The air will rush in, the speeding car will slam into the inrushing air and quickly decelera...

Re: EM Drive

I wish I knew the answer. I don't. I do know that energy can not be added to an evanescent wave by increasing the evanescent wave frequency, because evanescent waves don't have a frequency. They are not propagating waves in the sense we think of, rather they are expotentially decaying waves. But I ...
