Generate endless hot water without electricity or solar power



According to Appropedia: "When air or water is heated, it gains kinetic energy from the heating source and becomes excited. As a result, the water becomes less dense, expands, and thus rises. In contrast, when water or air is cooled, energy is extracted from the molecules and the water becomes less active, more dense, and tends to "sink." Thermosiphoning harnesses the natural density differences between cold and hot fluids, and controls them in a system that produces natural fluid movement. Several systems based on this technology are currently available—[the one highlighted in the following video uses wood as the fuel source]."

Britain’s first ‘Bio-Bus’ powered entirely by human and food waste takes to the streets

(The Guardian) Britain’s first ‘poo bus’ will take to the road on Thursday, powered entirely by human and food waste.

The 40-seat “Bio-Bus” runs on biomethane gas, generated through the treatment of sewage and food waste. It can travel up to 186 miles on one tank of gas, which takes the annual waste of around five people to produce.

The bus is run by Bath Bus Company and will transport passengers between Bath and Bristol Airport.

Luci inflatable solar lantern: eco-friendly, zero emissions and affordable—what more can you ask for?

(The Grommet) Luci is an inflatable, affordable, solar lantern that generates continuous light with zero emissions anywhere on earth independent of the grid; it can be charged under direct sunlight or cloudy skies (as well as incandescent light).

As easy to use as it is to deflate and stow, Luci’s durable, waterproof design makes it ideal for everything from boating and camping to outdoor entertaining, and power outages. In fact, lack of electricity was the inspiration for the idea. MPOWERD was co-founded by Jacques-Philippe Piverger, John Salzinger and Jason Alan Snyder. Principal inventor Jason Alan Snyder worked hand in hand with John Salzinger to develop the Luci lantern after an earthquake in 2010 left thousands without power in Haiti. Now, MPOWERD is on a mission to illuminate the lives of people who live in energy poverty all over the world.

Chocolate-based fuel and plant fiber car - A new wave of eco-friendly innovation


A team of scientists in Britain have harnessed the unlikely fuel source of waste caramel and nougat from chocolate manufacturer Cadbury Schweppes. As part of the experiment, Escherichia coli bacteria were fed the sweet left-overs from the factory. The bacteria then belched out hydrogen gas after a process of sugar fermentation and conversion of formic acid. This surprising source of hydrogen was subsequently used to power a small fan via fuel cell technology. As a highly efficient source of energy, fuel cells have a zero emission rate when used with hydrogen. Continue »
