For what I know it cannot be synthesised at all.

A new potential rocket fuel molecule. Trinitramid.

This was posted all around the web today. Interesting times ahead if the compound is indeed stable in solid form as the calculation have shown to be. Trinitramid should be 20-30 percent effective in comparison with the best rocket fuel available today. A rule of thumb is that for every ten per cent ...

Granted, the article is not that well written. Thermoelectric conversion can be defined in a quick and dirty way the amount of radiative energy we remove from a body under the form of electricity, so the Stefan–Boltzmann law will give you a rough idea. In general the source heat is considered stable...

Skutterudites, a new class of thermoelectric materials

Via Next Big Future: http://nextbigfuture.com/2010/12/thermoelectrics-could-be-improved-from.html Skutterudites, and this new knowledge about how best to arrange their atoms, could help improve their performance to 15- or 20-percent, at which point they become useful in many practical applications, ...

You actually didn't show anything. All the three instances you showed are not proving anything because they require you to believe (or have faith) in the exhistance of Christ or God (or the flying spaghetti monster) before even you can start to discuss those arguments. Betruger was very clear. Give ...

Last I heard it was under test by some chineese university, or so was the rumor.

Pretty interesting designs from the above links. I like the helicon one especially.

The suggestion is logic Ladajo, but I do not think it can solve the fundamental different starting point that is at the base of this discussion. Accepting one of the 2 starting points authomatically excludes the other. Not that I am saying that one of the 2 must be wrong. For what we know both start...

Anyone CAN make a theory and if the bulk of folk who think about such things hold to that theory, it is the prevailing theory. It matters not whence the theory came, merely that it IS the prevailing theory. SCIENCE TESTS all theory. Anyone can have his own ideas or personal beliefs, but they should...

I did. Numerical method full of hypothesis and semplifications based on older works. Might be all good or all bad as far as we can say now. Recognizing that a kit to test it against might be available when ELI gets online (anytime between 2015-2017). For the one who do not know what ELI is: http://w...

As per the debate on the other thread ['theory' versus 'discovery']; it seems a bit of an oxymoron 'theoretical... breakthrough'. One has a breakthrough, or one does not. Indeed. If you think you have a breakthru but are not quite sure, is that a "theoretical" breakthru or just a "hypthetical" brea...

Beautiful launch. If you think about how young this company is and how many bureaucratic obstacles they had to overcome, what they have achieved so far is truly amazing.
