Giant CO2 spheres invade NYC

With its many pedestrians and subway users, New York seems like one of the greener cities in the U.S. But it still produced a gob-smacking mountain of carbon emissions in 2010.

In the vid below from graphics firm Carbon Visuals, the 54 million tons of CO2 is illustrated as a mass of spheres that tower over the city, engulfing its buildings.

Some 75 percent of the pollution came from buildings, with the bulk of the rest from transport, according to the firm, which used city data. … Read more

Floppytable makes floppies relevant again

Here's a generational test. Look at this table. What do you see? If you see a weird-looking coffee table, then you're young enough to have no idea what a VHS tape or landline telephone is. If you see a floppy disk, then you should probably spend the $930 it takes to get a Floppytable for your living room.

The Floppytable is anything but floppy. It's made from hot-rolled steel and stainless steel, making it much stronger than the plastic originals. The table is nearly 28 inches wide, 18 inches deep, and 26 inches tall, so you won't be able to cram it into the floppy slot on your ancient PC.… Read more

Swedish town introduces light therapy to bus shelters

In Umea, Sweden, the forecast for Thursday is partly cloudy with a 10 percent chance of precipitation and a high of 25 degrees Fahrenheit. As I write this in dark and damp Portland, Ore., Umea doesn't sound so bad.

But the city, located some 400 miles north of the already northern Swedish capital Stockholm, is for most of the day this time of year cloaked in darkness, with the sun rising at almost 9 a.m. and setting just after 2 p.m.

So the local energy company Umea Energi has begun installing phototherapy lamps in 30 bus shelters … Read more

Microsoft speaks poop to power

The more data centers are built, the more power is consumed.

The more power is consumed, the more people rely on that power.

The more we rely on the grid, the more chance there is, perhaps, that something will go wrong.

The more we become reliant on the cloud, such a calamity will annoy more people who are desperate to, um, watch Netflix or stare at Instagram.

Microsoft doesn't want to risk taking any verbal dung from you on such matters, so it announced today that it is building a data center powered by, well, waste matter.

Yes, your Microsoft cloud uploads could soon be powered by your own personal downloads. … Read more

A3 E-tron previews Audi electric car

Ever since 2009, Audi has been showing off enticing electric cars under the E-tron name, its brand for any electrified power train. I finally got to drive one during a green industry conference in San Francisco, but it was a far cry from the original sporty-looking E-tron concept. However, the A3 E-tron looks a lot more like a car that Audi would put into production.… Read more

Pee power! African teens create urine-fueled generator

In a stroke of ingenuity that could have proven handy during Hurricane Sandy, four teenage African girls have come up with a urine-powered generator.

Duro-Aina Adebola, Akindele Abiola, and Faleke Oluwatoyin, all 14, and Bello Eniola, 15, collaborated on the invention, which they claim generates one hour of electricity from one liter (about a quart) of urine.

The pee-powered product made its debut at Maker Faire Africa in Lagos, Nigeria, this week. A post on the Maker Faire Africa blog describes the generator's workings in the following words: … Read more

Sustainable fishing 'SafetyNet' catches big prize

Imagine yourself as a little fish swimming far below the surface of the sea, just trying to make it in a big blue world. Suddenly, a horizon-encompassing net grabs you and takes you away from everything you once knew. Things go from bad to worse as the commercial fishing net rises and the pressure change kills you.

This fate, which often befalls millions of smaller non-target fish around the world every year, could change with the invention of the sustainable SafetyNet, which today was named winner of the prestigious 2012 James Dyson Award for design. … Read more

EnergySail promises wind-solar combo for cleaner shipping

Many shipping companies are experimenting with adding sails to cargo vessels. Here's a design in which the sails are also solar panels.

EnergySail is a concept by Japan's Eco Marine Power that harnesses and stores wind and solar power to reduce fuel costs and pollution. It would work as an additional source of power to a ship's main engines.

The devices would be fitted on anything from large bulk ore carriers to cable-laying ships, ferries, and coast guard patrol vessels, according to the company. An automatic control system would orient the sails and panels to catch the … Read more

Samsung solar-powered school shines in rural South Africa

There's something new(ish) under the sun in the rural South African village of Phomolong, where Samsung has built a gadget-laden solar-powered classroom -- in a renovated shipping container.

The Solar Powered Internet School -- a product of Samsung's corporate-social responsibility initiative -- has solar panels on the roof that can generate nine hours of electricity a day. That power's needed to juice the electronics inside -- a 50-inch electronic board, Samsung Internet-enabled solar-powered notebooks, Samsung Galaxy tablets, and Wi-Fi cameras.

Titan supercomputer debuts for open scientific research

Forecasting for weather like this week's "Frankenstorm" may become a lot more accurate with the help of the Department of Energy's Titan supercomputer, a system that launched this month for open research development.

The computer, an update to the Jaguar system, is operated in Tennessee by Oak Ridge National Laboratory, part of the DOE's network of research labs. Researchers from academia, government labs, and various industries will be able to use Titan -- believed to be one of the two most powerful machines in the world -- to research things such as climate change and … Read more
