5 Sources of Alternative Energy You May Not Have Heard Of
Wastewater produces electricity and desalinates water
A process that cleans wastewater and generates electricity can also remove 90 percent of salt from brackish water or seawater, according to an international team of researchers from China and the U.S.
Robots may receive urine-powered artificial 'hearts'
Unique salt allows energy production to move inland
Production of energy from the difference between salt water and fresh water is most convenient near the oceans, but now, using an ammonium bicarbonate salt solution, Penn State researchers can combine bacterial ...
Urine could be the answer to cheaper electricity
(PhysOrg.com) -- Urine can be an abundant fuel for electricity generation, according to British scientists in the first study of its kind.
Bacteria use hydrogen, carbon dioxide to produce electricity
Researchers have engineered a strain of electricity-producing bacteria that can grow using hydrogen gas as its sole electron donor and carbon dioxide as its sole source of carbon. Researchers at the University of Massachusetts, ...
Cheating favors extinction
Cooperative behaviour is widely observed in nature, but there remains the possibility that so-called 'cheaters' can exploit the system, taking without giving, with uncertain consequences for the social unit ...
You are not what you eat
The types of gut bacteria that populate the guts of primates depend on the species of the host as well as where the host lives and what they eat. A study led by Howard Ochman at Yale University examines the gut microbial ...

Renewable hydrogen production becomes reality at winery
(PhysOrg.com) -- The first demonstration of a renewable method for hydrogen production from wastewater using a microbial electrolysis system is underway at the Napa Wine Company in Oakville. The refrigerator-sized hydrogen ...
Onstott's discovery of worms in Earth's depths raises questions about life in space
After digging holes in the Earth's crust for nearly two decades, Princeton University geoscientist Tullis Onstott is now making headlines for unearthing "worms from hell."
