  • Algae in Paris Revisited

    On occasion we publish letters on Green Building Elements. In this case, Kstor, writing from France, is critical of the energy promises made by Ennesys and Origin Oil in a Jan. 11 post about growing algae on buildings using wastewater to then generate energy. In spite of real optimism to generate renewable energy using a…

  • Just Add Water: Scientists Using Silicon to Produce Hydrogen on Demand

    Super-small particles of silicon react with water to produce hydrogen almost instantaneously, according to University at Buffalo researchers. In a series of experiments, the scientists created spherical silicon particles about 10 nanometers in diameter. When combined with water, these particles reacted to form silicic acid (a nontoxic byproduct) and hydrogen — a potential source of…

  • NASA Launches Search For Green Rocket Fuel

    NASA seeks proposals from researchers and technologists for a potential green alternative to the highly toxic fuel that currently powers space flight.
