Keep in mind that that is just the engine they are talking about. While I'll agree that it does sound improbable, even if you have a silent engine, you will still be generating shocks which are LOUD, and the characteristic pressure N-wave will still be developed as the body moves through the...

Another cool and usefull site is http://www.efluids.com/ They have a number of good links and some pretty sweet images in the gallery. You should check it out.

Do you know the melting point of any of these catalysts? The decomposition of NOX can serve as a gas generator, creating oxygen and nitrogen, and can thermally sustain itself in the presence of a catalyst with relatively little activation energy. I would like to find a way to cost effectively...

Does anyone know what types of materials may be used to decrease the activation energy of 2N_2O->2N_2 +O_2. I think perhaps silver may work, but I need to find a material which will withstand the high temperature of decomposition thanks

DARPA has been looking into fuel cells that use air for powering micro airial vehicles. In a standard fuel cell a red-ox reaction (although it has been a looooong time since i was in chem) occurs and the electrons from this reaction are used to provide a current and electro motive force. I...
