Capturing excess heat to convert it into electricity can help the world become more energy-efficient, but currently technologies are expensive and not efficient enough. Panasonic is hoping to change that in the coming years with a tubular thermoelectric technology it has developed to tap wasted heat from sources such as hot springs and factories and (more…)
NASA has developed a system capable of growing large amounts of algae for biofuel production within a network of floating plastic bags, an innovation its developers say could ultimately produce a new fuel source.
There are so many smart new social innovation technologies coming out to create renewable fuels and power supplies. The latest discovery is that sewage plants are being used to not only treat waste but to also generate electricity. This knowhow is devised by Prof Bruce Logan, an environmental engineer specializing in water systems at Pennsylvania State (more…)
How Waste = Food
Imagine if we could create a super-efficient world where there was no waste… Actually, there’s no need to imagine it: nature is already ahead of us on this one.
In nature, almost all “waste” from one organism can be used as “food” or fuel by another organism—a (more…)
Mexico City has announced plans to close one of the world’s largest open-air garbage dumps as part of an initiative to convert more of the city’s waste into reusable materials or energy.
By the end of the year, garbage trucks will no longer be allowed to drop trash at the Bordo Poniente, a (more…)
A case study in Vermont suggests that it is economically feasible for dairy farms to convert cow manure into electricity using anaerobic methane digestion, provided there is adequate commitment from utilities, farmers, customers, and government agencies.
During a seven-year period, six dairy farms (more…)
