I was curious if a modified turbine the kind that is used in hydro-power dams (the Snail Shell type) if modified could a similar style turbine be powered by air? Also I’m talking on a smaller scale. I’m just toying with some ideas and was curious if this concept could actually be performed effectively or not due to pressure requirements. Also if that has already be done and you know of any websites or info I’d greatly appreciate any info you can offer. Thanks!
