Wind-power blimp takes to the air (video)

A video from Altaeros Energies shows a novel vision for powering remote locations.

The wind energy startup released a video this week of its prototype airborne wind turbine during its first test run in Maine earlier this year. The donut-shaped blimp has a spinning fan at its center, and it's tethered to a base station by cables that carry electricity from the blimp to the local grid.

The turbine is designed for remote villages or industrial sites where there isn't grid power and for places such as military outposts that need to rely on diesel generators.

IBM speeds push for 500-mile EV battery

Ten years from now, range anxiety for electric cars could be a thing of the past.

IBM today announced two partners for a project aimed at building a lithium air battery able to propel an electric car 500 miles. Scientists from Asahi Kasei and Central Glass with expertise in membranes and electrolyte chemistries will join IBM researchers on the initiative.

Called the Battery 500 Project, the goal is to design an "air-breathing" battery that will use oxygen from the air to drive a new type of battery chemical reaction and, in the process, deliver a big jump in … Read more

Greenpeace's clean cloud push: Hey, they've got a point

Commentary In its trademark smashmouth style, Greenpeace this week took cloud computing companies to task for using dirty energy -- and then came under fire itself over its methods and assertions.

Whatever Greenpeace's shortcomings, though, its activists have a point.

In the latest event of its "Clean our Cloud" campaign, Greenpeace activists yesterday rappelled off a building near Amazon and Microsoft offices and attached a banner which reads "Amazon, Microsoft: How Clean is Your Cloud?"

Earlier, it released three videos that poke fun at Amazon, Apple, and Microsoft by showing workers shoveling coal into a … Read more

Charger helps solve vampire power problem (video)

Who hasn't left their various mobile devices plugged in long after they're fully charged?

A new product -- still a prototype but expected to go on sale soon -- aims to solve the problem of so-called vampire power. Plug your device into the Mushroom GreenZero charger, and when your device is fully charged, the charger will turn off automatically. SmartPlanet's Sumi Das takes a closer look at the handy device.

This video originally appeared on SmartPlanet with the headline "Charging devices eliminate vampire power."

Gaming consoles consume copious amounts of energy

Electricity costs on game consoles have soared into the billions with tons of energy being wasted, according to a study (PDF) by researchers at Carnegie Mellon University. However, it doesn't have to stay this way.

The moral of this study: power down when done playing.

According to the research, 68 percent of all game console energy consumed in 2010 happened while in idle mode, which equaled 10.8 TWh of energy and about $1.24 billion in electricity costs. Overall, 1 percent of U.S. residential energy consumption in 2010 was spent on video game consoles, which is an … Read more

Apple slaps back at Greenpeace for dirty-cloud report

A day after being criticized by Greenpeace for its energy practices, Apple said Greenpeace's estimates for power use at the company's latest data center are much too high.

Apple said that its data center now under construction in North Carolina will use about 20 megawatts at full capacity. Greenpeace put the estimate at 100 megawatts.

Greenpeace gave Apple, Amazon, and other companies low marks for locating their data centers in areas that rely heavily on coal and "dangerous nuclear." Those companies also scored lower than competitors, including Google and Yahoo, because they disclose less information on … Read more

Hybrids can be less polluting than coal-powered EVs

A study has found that cars with very high gas mileage are less polluting than electric vehicles charged up in coal-heavy regions.

The Union of Concerned Scientists released a report today called "State of Charge" that finds that on average plug-in cars are less polluting than gasoline-powered vehicles in the U.S. But the greenhouse gases emitted from electric vehicles depends on the sources of electricity.

The study centers on a heated discussion in auto circles. Automakers have sometimes referred to electric vehicles as "zero emissions," which is misleading because most plug-in drivers charge their cars … Read more

Nest Labs to Honeywell: We'll see you in court

Nest Labs today fired back at Honeywell over its patent infringement case against Nest, claiming the thermostat giant is using its patent portfolio to stifle innovation.

The company also hired Apple's former chief patent counsel, Richard Lutton Jr., as it plans for a legal fight with Honeywell in the years ahead.

Founded by former successful Apple engineers, Nest Labs started selling its $250 Learning Thermostat last year and quickly sold out amid rave reviews over its design and ability to automatically set schedules.

Honeywell in February filed a suit claiming that Nest infringed on several of its seemingly broad … Read more

IBM brings smart charging to Honda Fit EVs

To a computer company like IBM, plug-in electric vehicles just look like more nodes on the network.

IBM tomorrow is expected to announce a demonstration project with Honda and California utility Pacific Gas & Electric to charge a fleet of Honda Fit EVs without disrupting the grid.

The smart-charging project will also test smartphone and Web-based apps for consumers, giving them an estimate of charge time and location of charging stations.

The power grid as a whole has the capacity to accommodate millions of plug-in vehicles, say experts. But if there's a concentration of electric cars charging at once, … Read more

Corkscrew wind turbine brings juice to Indians stadium

As the Cleveland Indians play their home games, an experiment in industrial design will be spinning just overhead.

The ball park is hosting a wind turbine that uses a helix-shape tower to squeeze more power out of conventional wind turbines. The structure increases the wind speed, a technique companies have long pursued to lower the cost of wind energy.

The Progressive Field installation is a prototype designed by Majid Rashidi, a professor at Cleveland State University. The 40-foot-high, 18-foot-wide helix turbine will be installed for a year for testing and is expected to generate 40,000 kilowatt-hours a year, or … Read more
