WELLINGTON: Cars that run on a by-product of human sewage could replace petrol vehicles within a span of three years, according to a report. A car manufacturer in Japan is backing a consortium which is investigating a process that turns sewage sludge into hydrogen for use in fuel-cell vehicles.
Microbial fuel cells are a variant of hydrogen fuel cells. These energy systems use bacteria to consume organic waste and produce methane or hydrogen gas. The gases produced by the bacteria are then used in the fuel cell to generate electricity. Microbial fuel cells are often hailed for their ability to address two issues at once — energy and waste — and do so efficiently. There may be a way to make the energy systems even more efficient than they currently are, however, which may also make them more attractive for commercial use.
Smelling a sweet idea, Microsoft plans to do exactly that with its 300 kW cell. The installation, which also serves as a test of Microsoft's latest modular data centers, will consume 200 kW, feeding the remaining third of the generating capacity to power and heat the wastewater plant.
It may not be an appetising thought when you're putting the dinner on - but a new loo turns human waste into fuel. The 'No Mix Vacuum Toilet' is an aeroplane-style vacuum toilet which splits waste into solids and liquids. Liquid waste is processed for chemicals such as phosophorous for fertilisers. Solid waste is processed in a bioreactor to create 'biogas' - a methane-rich gas which is, the scientists promise, odourless and safe for cooking.
TREATING waste water is energy intensive. In the US, it sucks up the equivalent output of four of the country's biggest power plants every year. But it needn't be such a drain on resources - soon it might be able to earn its keep. A team led by Hong Liu from Oregon State University in Corvallis has plans for microbial fuel cells that will reclaim energy from waste water and produce around 2.87 watts per litre of waste water. That is almost double the amount of electrical power usual for such a cell.
The price of the new product will be 1,995,000 yen (with the standard backup heat source; including tax; excluding installation fee). This is about 760,000 yen less than the recommended retail price of the "Ene-Farm" model currently on the market, made possible by a reduction in the number of components. The new product also achieved an overall efficiency of 95.0% (LHV)*3 - the world's highest*4. It is the first time that the recommended retail price of an "Ene-Farm" product in Japan has been less than 2 million yen.
With over 5,000 fuel cells providing heat and energy for conventional homes up and down Japan, the BBC has learnt that companies such as electronics giant Panasonic are in talks with EU governments about the possibility of bringing these proven energy and carbon-saving devices to market in Europe and elsewhere.
Science This Fuel Cell Keeps Running Even When It’s Out Of Fuel Jamie Condliffe 4 July, 2012 2:00 AM Share Discuss Bookmark Fuel cells are amazing things, but just like any portable energy source, they occasionally need topping up with juice. This one, however, can keep on going even when it runs out of fuel. What kind of sorcery is this? In fact, this is a new solid-oxide fuel cell (SOFC) developed at Harvard that converts hydrogen into electricity. But along the way, it also creates energy which it can store away, a little like a battery.
We’ve been promised an exciting future with gadgets perpetually powered by magical fuel cells, and a company called Lilliputian Systems is taking the first steps towards tomorrow with its fuel cell-based USB charger that will soon be available from Brookstone.
Long road trips can be a pain, literally, since bathrooms are usually very hard to find in the middle of nowhere. Fortunately (or unfortunately), a Chinese company has developed a car seat that comes with a built-in toilet / urinal. However, we're not quite sure where the waste gets stored since there appears to be some kind of filtration system in place as well. Continue reading for more pictures.

LOL I don't believe you will actually be pooping into your car! More using the hydrogen from the poop and filling your car with that... But that is a funny pic so thanks for sharing...
Am I to believe that you are not confident in the potential of poop? Even with the mountain of excreme.. I mean evidence I've provided? Would you like to see more?
Poop is one thing I am very confident in! I gave you a SnF for the post. It is technology that will become available eventually. But just like anything else, it won't be "viable" until the people that control the oil also control the poop...........
Very exciting advances, thanks for bringing this to my attention all in one easy to read post. Now I just have to wait for the free-market to catch on here in the states. If it doesn't make a large profit it won't replace current technology it seems.

We will soon be able to buy a rechargeable water powered battery. Alternative energy is there, but there are still good odds that big companies can afford to keep these things down....we'll see
