Energy from sewage- revisited
We reported yesterday about Dr. Bretschger’s (J. Craig Venter Institute) MFC (microbial fuel cells) to recover energy from wastewater. Today, we’ll discuss a slightly different version, under development at Penn State University and for which results were recently published in … Continue reading
And, the wind, she cries— Power?
We “know” that petroleum as a fuel source is running out. Not as fast as we once thought- only because as the price rises, sites and sources that were out of reach (economically) become more feasible. Think Athabascan tar sands, … Continue reading

Solar to Steam Plant Operational
When it comes to power generation, there are some truisms. Unless we develop new engine technology, we are going to need fluid (liquids or gases) fuels or batteries to run our cars. But, the bulk of commercial and residential energy … Continue reading
Solar Cooling- now!
Not surprisingly, about 50% of our energy consumption is devoted to heating and cooling our buildings. (This data is substantiated by the World Business Council for Sustainable Development). And, that means that we should pay more attention to these needs- … Continue reading
