Going off on a slightly different tangent here: I know that the temperature in the combustion stage of a gas turbine engine can easily exceed 1600 degrees C, but do you know roughly how hot it would be at the intake. I assume that it is highly design dependent, and it is being constantly cooled...

Thank you very much for such a detailed and quick response! I have just one more query: is it true that turbine engines are more compatible with a wider variety of fuels? Could I, for example, burn hydrogen as my fuel, but when it runs out, simply use petrol from a normal petrol station? (which...

I was thinking more along the lines of the 'resting state' (no voltage) being tight, and then expanding when you need it to (by applying a voltage). I am under the impression that you can get EAPs that expand when a voltage is applied, as well as EAPs that contract when a voltage is applied. Is...

I know that this topic has already been covered (kind of) in a separate forum post, but it became rather confused and there were many differing and contradicting opinions/supposed facts, so I just want to clarify a few things. Firstly, are gas turbines more or less efficient (useful mechanical...

Hello internet! I understand the basic principle of EAPs (you apply a potential difference and it moves) but I can't for the life of me find any specific, named EAPs that fit my requirements. If possible could you tell me if you know of an EAP that: Works in a normal environment (air, room...

Sorry I didn't reply sooner but my internet has been down for almost two weeks! I followed Windadct's advice for using the hydrogen fuel for combustion instead and got full marks! Thanks for all your help.

Could you possibly add an explanation to go with that equation? I'm guessing it means approximately 100 Amps per m^2 of the surface area of the electrodes (according to this source: http://www.mpoweruk.com/hydrogen_fuel.htm). Thanks for your help.

Hello internet! Please excuse any silly questions as I am not (obviously) a professionally educated physicist (yet!). I was doing a school project on alternative energy sources and became rather interested in hydrogen fuel cells, specifically to replace batteries in small scale, high energy...
