In college a few years ago, we had to come up with / engineer the most efficient electricity creating energy plant. We ended up building a 12inch tube and used combustion to spin a small turbine, connected to a shaft which spun an electric morot; creating around 950watts of energy. In this experiment we used Propane and Oxygen tanks. We, by far did not use much propane/oxygen to create this amount of power. The only drawbacks were the heat created (EXTREME) and the bursting startup flame (pretty cool).

I am thinking about trying this out;


Instead of powering an electric engine, I could power a fan... I can built it and bring it to the lab eventually, maybe I can achieve around 1500 to 3000 watts with a good compressing O/P shaft...
