Poop-powered sewage treatment system fits in a shipping container : TreeHugger

Poop-powered sewage treatment system fits in a shipping container : TreeHugger.

The Bill and Melinda Gates Foundation’s Reinvent the Toilet competition has funded the development of a number of different approaches to dealing with human waste. Duke’s Pratt School of Engineering has received a grant of $1.18 million to build a system that is very different from last year’s winner.

The Duke team doesn’t really reinvent the toilet at all, but reinvents sewage treatment by packing a very sophisticated processing system into a 20 foot shipping container. In many communities, people empty their latrines into the nearest river; with the Duke system, they either have their cisterns pumped or they carry it to the container. It can handle the waste of a community of 1200 people.



BBC News – Let’s go solar: How communities make energy together

BBC News – Let’s go solar: How communities make energy together.

Sizzling temperatures across the UK make most of us think of barbecues, swimming or sun-tan lotion.

But in part of south London, the thoughts of Agamemnon Otero are on the kilowatts per hour being generated on local rooftops.

“It’s a great summer to install solar panels,” he says.

“On a day like today, in the full sun, we’ll be creating more energy than all these buildings need.”

BBC News – Solar Impulse plane sets off for New York in last leg

 

BBC News – Solar Impulse plane sets off for New York in last leg.

The Solar Impulse plane has taken off for the final leg of its bid to cross the US on solar power alone.

The craft set off at 04:56 local time (08:56 GMT) on Saturday from Washington DC on a course for New York’s John F Kennedy airport.

Pilot Andre Borschberg anticipates a journey time of about 21 hours.

The Across America transcontinental bid began in San Francisco, California, and included stopovers in Phoenix, Arizona, Dallas, Texas, and St Louis, Missouri.

The Solar Impulse HB-SIA has the same wingspan as an Airbus A340 but at a weight of just 1.6 tonnes. By comparison, a fully laden A340 weighs about 370 tonnes.

The plane’s wing and stabiliser are covered with nearly 12,000 solar cells, which drive its four propellers and charge the plane’s 400kg of lithium-ion batteries for night-time flying.

Carry Me Cargo Bikes

Carry Me Cargo Bikes.

What are cargo bikes?

Cargo bikes are bicycles specially built to carry goods, people’s stuff, children, adults, or a combination of all of these. Even dogs… or cats. They’ve come a long way since the traditional ‘butchers boys’ bikes which basically had a tray with a box in front of the handlebars.

Nowadays cargo bikes they can replace cars for many local journeys, and can have three wheels or even four. They can be purely pedal-powered, or can have electric motors to assist your knees. They can be nippy and slimline like the Dutch Bakfiets, or vast containers like the Danish Christiania. They can look a lot like a normal bike but simply longer, like the American Yuba; or they can be wide and low like the go-kart-like Brox.

Or, you can customise your own ‘normal’ bike to be far more practical by adding a big basket, roomy panniers, or a trailer – all removable, flexible, and good value for money.
