New MIT-developed materials make it possible to produce photovoltaic cells on paper or fabric. The technique represents a major departure from the systems used until now to create most solar cells, which require exposing the substrates to potentially damaging conditions, either in the form of liquids or high temperatures.

Remote villages without access to the power grid must rely on diesel or petroleum generators for electricity, which means they have power only when they can get fuel. Windlift develops portable airborne wind energy (AWE) technology for post-conflict reconstruction, disaster relief, and third-world development.

Large wind farms are being built around the world, but operators are still searching for the most cost-effective and efficient way to arrange the massive turbines. To help steer wind farm owners in the right direction, Johns Hopkins University researchers devised a new formula through which the optimal spacing for a large array of turbines can be obtained.

Stanford engineers have discovered a process called photon enhanced thermionic emission (PETE) that simultaneously combines the light and heat of solar radiation to generate electricity, and could offer over double the efficiency of existing solar cell technology. The process could reduce the costs of solar energy production enough for it to compete with oil.
