MIT researchers develop angle-selective solar thermophotovoltaic system for power generation without using mirrors to concentrate sun’s heat

Green Car Congress

The key is to prevent the heat from escaping the thermoelectric material, something the MIT team achieved by using a photonic crystal: essentially, an array of precisely spaced microscopic holes in a top layer of the material.

REV Building Four Converted Battery-Electric Vehicles for US Military TARDEC Program; Electric Ford Escape and F-150 Vehicles as Part of Micro-Grid Project

Green Car Congress

The order is for three REV 300ACXs and one REV 300AZX based on the Ford Escape and Ford F-150 platforms, respectively. Using REV’s control strategies, the APVs energy storage systems can be remotely notified to respond in real-time and store intermittent sources of energy such as solar or wind power.

Stanford solar tandem cell shows promise for efficient solar-driven water-splitting to produce hydrogen

Green Car Congress

Researchers at Stanford University, with colleagues in China, have developed a tandem solar cell consisting of an approximately 700-nm-thick nanoporous Mo-doped bismuth vanadate (BiVO 4 ) (Mo:BiVO 4 ) layer on an engineered Si nanocone substrate. The nanocone/Mo:BiVO 4 assembly is in turn combined with a solar cell made of perovskite.

The cloud responses, in turn, are related to the profile of atmospheric solar heating and corresponding changes in temperature and relative humidity. Robert Allen/UCR) Both types of energy—longwave (from Earth) and shortwave (from sun)—escape from the atmosphere more than they are absorbed into it.
