Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

In 1975, General Ernesto Geisel, then-president of Brazil, ordered the country’s gasoline supply mixed with 10% ethanol. The level was raised to 25% over the next five years, which was intended to maintain a constant Brazilian gasoline supply for an ever-increasing demand. As used in this section and Sec.

Manchester team proposing graphene-based ballistic rectifier for waste heat recovery

Green Car Congress

Conventional devices with similar conversion efficiencies require cryogenically low temperatures. Rectifying diodes let electrical current flow in only one direction; mainly used for power supply operation, they convert AC to DC current. —Song et al. Singh et al. 2015) Bottom: Illustration of graphene-based ballistic rectifier.

Conversely, high coating thicknesses for the electrodes produce a high energy density. A first test setup located near Ingolstadt recently started supplying the grid. A container for four traction batteries of various sizes works in tandem with a photovoltaic system that is capable of supplying up to 20 kW of power on sunny days.
