Innovation is when two or more things combine to make something new. Or get rid of something.
Like the startup making wind turbines minus the rotor blades (the latter are neither sustainable nor safe for birds.) The cylindrical turbines vibrate in the wind, generating electricity as they go.
Gears, brakes or oil? Not required. A 2.75 metre high turbine can create 100 kilowatts. Silently.
Thanks to its compact design it can be deployed in different sizes in cities or residential areas. A Spanish startup is developing the concept further together with Norway’s state energy company.
In England, meanwhile, a startup will employ the technology in streetlights, using the air displacement created by passing cars to illuminate the streets.
