I’ve always been fairly fascinated by the idea of a helium turbine. Maybe it’s because they conjure up an image of a bizarre future where the skies are filled with giant turbine balloons. One of the recent innovations that caught my eye came by employing a very simple-sounding tactic: increasing the height of the balloon.
Altaeros researchers, hailing from MIT, found that by simply increasing the balloon’s height from one hundred meters to three hundred meters, they would increase the energy output by two. The rotating piece is set inside the helium balloon, which will then float to three hundred meters. Electricity is routed to generators through the balloon’s anchor-lines.
