Joby Energy is developing airborne wind turbines which will operate in the upper boundary layer and the upper troposphere. While knowledge of the tremendous energy in high-altitude wind is not new, recent advances in power electronics, sensors, and control systems now make the technology practical.

Joby Energy’s multi-wing structure supports an array of turbines. The turbines [...]

Physalia is a vessel, 100% self sufficient in energy, whose bionic structure is inspired from the pneumatophorous called also “Physalia physalis”, from Greek physalis that means “water bubble”! As this aquatic pneumatophorous, the project is relevant by its perfect symmetry, its oblong shape and its translucent aspect. It is a sum-up of the nature and [...]

“Oyster”, a giant flap twice the height of a double-decker bus which swings back and forth with the waves. Every time the flap moves, the action compresses hydraulic pumps which force water through a pipe to the shore where it drives a generator.

A fleet of 1,900 unmanned ships, each weighing 300-ton, powered by the wind would criss-cross the oceans, sucking up sea water and spraying it from the top of tall funnels to create vast white clouds. These clouds would reflect a tiny proportion, between 1 and 2 per cent, of the sunlight that would otherwise warm the ocean.

Scott & Julie Brusaw are the founders of Solar Roadways. The Solar Roadway is a series of structurally-engineered solar panels that are driven upon. The idea is to replace all current petroleum-based asphalt roads, parking lots, and driveways with Solar Road Panels that collect and store solar energy to be used by our homes and [...]

The Sahara Forest Project combines two proven technologies in a new way to create multiple benefits: producing large amounts of renewable energy, food and water as well as reversing desertification. A major element of the proposal is the Seawater Greenhouse; a brilliant invention that creates a cool growing environment in hot parts of the world [...]
