A renewable energy technology company in Australia designed this power generation system inspired by the shape of the tailfins of sharks, tuna and mackerel. The currents on the ocean floor impose a force on the fin of the BioStream device. The to-and-fro motion of the fin is directed into a specially designed gearbox that converts the oscillating motion into a rotational motion that drives a conventional dynamo.

The fins are approximately 15 meters high (50 ft); the tails are 20 meters (66 ft) long. Systems are being developed for 250kW, 500kW, and 1000kW capacities to match conditions in various locations.

Should men be able to give birth to children?


Joyce Nabuurs: To me this question seems to be a logical next step in the emancipation movement of the past century. More and more women entered the workspace, but the responsibility for pregnancy and childrearing remained female.
