NoMix Toilet. Photo: Flickr Technological Innovations in the Bathroom? You Bet! Being green is all about solving problems and grabbing overlooked opportunities. It turns out that there's such a double-win in most bathrooms around the world; if we had "NoMix" toilets that separate urine from solid waste, municipal wastewater plants would have a significantly easier task (and produce more methane to generate electricity), and we could much more easily extract precious nutrients like phosphorus and nitrogen for use as fertilizer (instead of using fossil fuels). So what's stopping us from going NoMix?...Read the full story on TreeHugger

Image: MIT Could Store Power at 100x More Energy/Weight Than Lithium-Ion A team of scientists at MIT has discovered a new way to generate power with carbon nanotubes. In a paper titled "Chemically driven carbon-nanotube-guided thermopower waves" published in Nature Materials, they describe how they made "thermopower waves" flow through the nanotubes, generating a significant amount of power relative to the size of the nanotubes. This opens up new areas of research in energy gener...Read the full story on TreeHugger

Greenpeace, and others, scolded the company--which many consider among the most innovative in the world--for making an big investment in the dirty fuel. Facebook retorted that by hous...Read the full story on TreeHugger
