The flow of rivers can help generate electricity. So too five long, curved tube halves. At least, according to the patented design of a Lisbon-based startup. The parts are fastened to a pole, making a low-maintenance wind turbine. As the technology is scalable three sizes of the noiseless, aerodynamic turbine are planned. A small 100W generator, 1.2 metres tall;...

The smallest wave movements can be converted into electricity. Air streams, meanwhile, power wind turbines. But their enormous blades take up a lot of space and only last for 15 years. Instead of vibrating alternatives without blades, a founder from New York is backing a slender design whose vertical axis is divided into individual floors like a building. Fixed...

Birds base their flight path on the earth's magnetic field. Meeting a wind turbine en route, however, is unfortunate for both bird and turbine. Which is why a startup from Greece has developed a system that diverts the animals while simultaneously minimising the off-time of the electricity generators. Thermal imaging- and high-resolution cameras provide round-the-clock surveillance for critical areas...

Implants can be nourished by the body's store of glucose, while batteries can be powered by air moisture. Now, using an A5-sized device, a research team from Singapore has managed to generate electricity from a light breeze. A long plate with a cube on its end is fixed to one side of a small base body. The plate vibrates...

Cycling, running and playing tennis are not just beneficial for our health. A new portable wind turbine designed by a Canadian startup, which focuses on sustainable research and development, also supplies electricity. Depending on the strength of the wind, the 1.3kg turbine can generate up to 40 watts. An aluminium tripod with tensioning cables keeps it firmly planted in...

The more bees in a colony, the more combs with honey. A startup from Berlin has developed a scalable, modular system, which - like this Norwegian-based startup - is big on miniature wind turbines. The micro-turbines have been optimised over years of research and field tests. They are extra quiet, and can generate energy individually or as part of...

What links coconuts with rum and coffee? They are all shipped from overseas. Now a French company is aiming to make sea transportation more environmentally-friendly. Its 80-metre-long sailing ship, an alternative to this electric freighter, will have 700㎡ sails and be powered by wind. By winter 2022 the company should have 4 such vessels, travelling between Europe and destinations...

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...
