water heated in a microwave oven

[CrazyEwok]

I remember reading a while ago (few years now) that someone rigged a lawnmower to run on water by compressing it and them using a flash from some part out of a microwave. His problem was keeping the power to maintain the microwave component. Possible thought for a conversion or just to look it up... Movie on thetube more than likely. Still interesting... Interesting test (how the guy with the lawnmower said he discovered it) film canister with water in it (quantity unknown) in the microwave on high... POP!!!

with reference to the idea of getting hho from ice..

this may or may not work, but what i would say is that it would probably use more energy that doing it in water. my take on this would be like this.

water in a liquid state is in constant motion, the molecules of water are also in motion, the molecules actually move in 3 different ways at the same time.  this way when we try to break it there is room for the bonds to move and break

however if the water were frozen and you tried to get hho from it first of all you will use energy melting the ice to liquid but in the very same instance it becomes liquid the bonds will break.

this leads to the conclusion that if we were to use water at 1degree c this would be the best bet.

now here is food for thought. lets just say that 1 degree turns out to be the magic temperature, how would we keep the temperature this low ? refridgeration tends to use a lot of power.

i belive the key to be in the normal temperature range.

@ Hydro-Cell:

You may be correct.  But, what if, since the molecules are bunched together and less active in the frozen state, it turns out to take LESS energy to separate them?  You may not have to work as hard to overcome their bonds as their energy state is lowered due to the freezing?  This is just a thought, I have no basis in fact to support this idea.  I was thinking along the line of what happens in a superconductor.  When you reach the ideal temperature for that material, resistance goes to 0.  Like you said, the ideal temperature for water may be just a tick above the freezing level where it is still liquid, or, if I am correct, just below it.

Either way, you are correct in that unless it really increases production by an order of magnitude, any gains would be lost to the energy required for cooling to either just above or just below 0c.  Of course this may work well outside in the winter for producing gas for heating purposes but, I really have no idea if there would be any improvement or not.

High-temperature electrolysis

High-temperature electrolysis (also HTE or steam electrolysis) is a method currently being investigated for water electrolysis with a heat engine. High temperature electrolysis is more efficient than traditional room-temperature electrolysis because some of the energy is supplied as heat, which is cheaper than electricity, and because the electrolysis reaction is more efficient at higher temperatures

Hope this helps.

@ Hans:

Oh well, guess I was wrong then.  It isn't the first time.... ha ha.  Thanks.
