Summary:
Researchers are trying to convert human fecal waste into butanol to power cars of the future. Butanol is a high-energy fuel similar to gasoline. Using genetically engineered fungus, a scientist at Washington University in St. Louis believes it could one day be produced from one of the world' s most plentiful waste products.

Denver Zoo Using the Power of Poo

Buzz60 (Mar. 23, 2012) — It's only a prototype now but the Denver Zoo is using animal poop and trash to power an electric rickshaw. The plan is to test the fuel's efficacy to eventually power an entire elephant pavalion. It's all part of a green experiment that will save money.

Studio Guest: Dr. Brigitte Knopf, Climate Scientist

Deutsche Welle (Sep. 11, 2011) — Dr. Brigitte Knopf works for the Potsdam Institute for Climate Impact Research. She focuses on energy systems and their effect on the climate.DW-TV: Welcome to the program. Scientists from the Max-Plack-Institute suggest that wind energy is limited. What's your take on that?Brigitte Knopf: First of all it's fully correct that there is in principal a physical limit on the wind potential. But it's not relevant for energy supply for the whole world. So it's not relevant for today or for 2050 or even 2100. So nothing to worry about at the moment?Not that much, no.Would you agree that solar power is the renewable that has the most potential at the moment?At the moment yes, it has a big technical potential. But you also have to consider the costs and you have to compare the different technologies and what is less expensive.Most worldwide energy needs at the moment are still being met by carbon fuels: oil, natural gas, coal. Renewables now only cover 13% of energy needs. Only a tiny fraction

Brazil: The Solar Project in Florianpolis

Brazil: The Solar Project in Florianpolis

Deutsche Welle (June 17, 2013) — Solar power has so far played a minor role in Brazil. But now, with German aid, the country's largest photovoltaic power plant is being installed in the state of Santa Catarina, with a target capacity of 1 megawatt. Until now, only 2.5 MW of Brazil's power portfolio has been covered by solar, less than the 0.01% of the solar power share in Germany. Yet in the Earths largest tropical country, the potential is unlimited.

Rust Brings Boost to Solar Energy Potential, Say Scientists

Rust Brings Boost to Solar Energy Potential, Say Scientists

Reuters (Feb. 8, 2013) — Using the power of sunlight, Swiss scientists are developing methods of extracting inexpensive, safely transportable, hydrogen fuel from iron oxide - commonly known as rust. The process essentially converts solar power into hydrogen, vastly increasing the potential of solar energy to serve as a viable renewable energy source across the world. Jim Drury met the scientists behind the research.
