Mike writes "Rather than let their sewage go to waste, the city of Oslo recently announced that it plans to cut carbon emissions by converting 80 public buses to run on biomethane generated from raw sewage. The city plans to adapt two sewage plans with the technology this September, and the new biogas buses will be quieter and will cut 44 tones of C02 per bus per year."

Jason S. writes to tell us that for those seeking to "go green" or those just wishing to try something different, RTI now offers a printer that uses coffee instead of ink. In addition to recycling your grounds, the printer also uses good old fashioned elbow grease to move the grounds cartridge back and forth, saving power. Sounds like a novelty that will die quickly as human sloth reasserts itself. "Hosted by Core77 and Inhabitat, this year's Greener Gadgets Design Competition resulted in an incredible crop of innovative consumer electronics designs, and we're excited to offer you the first scoop on some of our favorite designs! Jeon Hwan Ju's RITI printer works by replacing environmentally un-friendly inkjet cartridges with the dregs from your daily coffee. Simply place used grounds in the ink case, insert a piece of paper, and move the ink case left and right to print text."

tsamsoniw writes "Singapore-based Atlantis Resources Corporation, which brings to the table tidal-turbine technology, is partnering with Scotland-based datacenter developer Internet Villages International) to construct a tidal-powered 150MW 'Blue Datacenter,' InfoWorld reports. If all goes to plan, the facility will eventually be powered entirely by clean energy produced by tidal-current turbines in the Pentland Firth, the stretch of water between the far north Scottish mainland and Orkney. The firth's currents could generate 700 megawatts of electricity by 2020." And reader Mike writes "Here's something to raise a glass to: recently the Rothes consortium of whiskey and scotch distillers announced that they have partnered with Helius Energy to install a power plant fueled entirely by whiskey by-products. The completed plant will use biomass cogeneration to convert draff and pot ale from the distillery into 7.2 MW of electricity — enough to power 9,000 homes."

Mike sends along a couple of items of interest to those anxiously awaiting the era of production electric vehicles. First, there's the upcoming Aero EV, which Shelby Supercars claims will charge in just 10 minutes and will be able to produce over 1,000 horsepower, powering the vehicle from 0-60 mph in less than 2.5 seconds. Then there's the announcement by Aptera of the first pre-production model of the Aptera 2e, which will have a top speed of 90 mph and go around 100 miles on a charge. This EV also features a strong and aerodynamic body, a lithium-based battery, front-wheel drive, and an improved door design. Release is planned by October of 2009.

Jason Sahler writes "When the East Japan Railway Company (JR East) decided to invest in alternative energy sources, it only had to look to its users for the perfect source of energy. Recently the company decided to update their Tokyo Station with a revolutionary new piezoelectric energy generating floor. The system will harvest the kinetic energy generated by crowds to power ticket gates and display systems."

Mike writes "Recently San Francisco, San Jose, and Oakland unveiled a massive concerted effort to become the electric vehicle capitol of the United States. The Bay Area will be partnering with Better Place to create an essential electric vehicle infrastructure, marking a huge step towards the acceptance of electric vehicles as a viable alternative to those that run on fossil fuels." Inhabitat.com has some conceptual illustrations and a map showing EV infrastructure, such as battery exchange stations, stretching from Sacramento to San Diego — though this is far more extensive than the Bay Area program actually announced, which alone is estimated to cost $1 billion.

Jason Sahler writes "Recently St. Lucie County in Florida announced that it has teamed up with Geoplasma to develop the United States' first plasma gasification plant. The plant will use super-hot 10,000 degree Fahrenheit plasma to effectively vaporize 1,500 tons of trash each day, which in turn spins turbines to generate 60MW of electricity — enough to power 50,000 homes!"

leprasmurf writes "Inhabitat has posted an article detailing a recent announcement of a process to turn CO2 into fuel. The process, which used to be considered too energy inefficient, uses a multi-step, low pressure, and low temperature biocatalyst to break the CO2 into 'basic hydrocarbon building blocks.'"

Mike writes "Winner of the '08 Innovate or Die competition sponsored by Google and Specialized, the Aquaduct is a pedal-powered concept vehicle that transports, filters, and stores water. The design has massive implications for communities where safe and secure sources of drinking water are not readily accessible."

Mike writes with this tantalizing excerpt: "Dale Vince of Ecotricity and engineer Richard Jenkins are setting up on the salt flats at Lake LeFroy in Western Australia, hoping to catch the right breeze and break the wind-powered landspeed record of 116.7 mph in their sleek wind-powered vehicle, the Greenbird."

longacre sends along a Popular Mechanics article on the growing interest in magnetic levitation trains in the US. It's unclear how many will actually get built here, at $100 million per track mile. (In recent years we've discussed maglev projects in China and Germany.) The article has a map of many proposed transportation projects in the US, some of them maglev, and a video of a General Atomics maglev prototype in action. On a related note, an anonymous reader recommends this article on a proposed maglev wind-power turbine, said to offer the promise of replacing 1,000 conventional wind turbines.

The Great Pulgoso sends us word that Norwegian energy group Norsk Hydro has signed an agreement with Siemens to develop floating wind turbines. The companies agreed on a schedule that would see a prototype in the North Sea by 2009 and a working wind farm using 5-megawatt generators by 2013. (Norsk Hydro unveiled the design in 2005.) Inhabitat.com has taken the giant illustrations from the Norsk Hydro site and reproduced them at a reasonable size. The design features a steel tube 200 meters long. It extends 80 meters above the sea surface and has three 60-meter blades. The whole thing is anchored to the sea floor by three tethers. The developers expect to be able to install the turbines in waters up to 700 meters deep.
