Snow Power

The system was developed by Koji Enoki (pictured) an associate professor at Tokyo’s University of Electro-Communications.

Estimates show that it  can produce electricity as efficiently as solar power.

The snow is put into an enclosed pool and heat transfer tubes are placed in the snow.

The outside air is heated by the sun and the difference in temperature creates a convection current in a coolant inside turbine which rotates it to generate electricity.

Aomori spends tens of millions of dollars every year to remove snow from roads which is then dumped in the sea. 

If the test works, snow will instead be taken to generating stations.

The plan is to bring the system to the onsen (hot springs) in the north of Japan which gets plenty of snow.

“The greater the temperature differences, the greater the efficiency of power generation,” says Enoki.
