French start-up Heat2power claim to have a new technology that increases fuel mileage using heat energy otherwise dissipated via the exhaust pipe. There are others that use a similar system, but the company claims that their device captures even more energy. The basics include installing an additional cylinder linked to the crankshaft with a clutch that is powered by exhaust heat. The exhaust gases circulate inside a heat exchanger linked to a closed-circuit filled with compressed air. Hot air enters the additional cylinder. Once it has moved the piston, the air goes to an intercooler and returns to the heating unit forming a closed circuit. The system is compatible with any ICE engine, the company claims. Their numbers also say the device reduces fuel consumption up to 20 percent in urban driving and 35 percent on the highway. Autobloggreen original article here.

Leviathan Energy has completed initial testing on their Wind Energizer unit and is reporting gains in wind turbine output in the ballpark of 30% - and as much as 150% at lower wind speeds. The idea is that by placing site-specific structures at the bases of the turbines you can shape the flow of air in the vicinity of the turbine so that the highest velocities get targeted at the blades. Leviathan's early testing has been conducted on a relatively small scale, using commercially-available small turbines with 3-meter blades but they are planning on exploring opportunities for third-party testing and certification on a commercial scale wind farm.
