The new Mark VIII armor for Iron Man 3 is revealed

What kind of armor will Tony Stark wear in Iron Man 3? That question has been answered at Comic-Con International, where the new costume is on display at the Marvel booth.

Here’s Wired senior editor Peter Rubin with an exclusive look at the new armor, as well as a chronological spin through the various power suits donned by Robert Downey Jr. in the hit superhero movies.

Video games wasted about 1% of America’s electrical energy

A new study from Carnegie Mellon University found that in 2010, video games wasted about 1% of America’s electrical energy.

They found that up to 75% of energy consumed by video game consoles is during idle use, because the machines don’t have an auto-power-down feature (like every computer does).

The authors of the study say the cost of implementing this feature is marginal and would save more than $1 billion in utility costs.

More details:

- By the end of 2010, over 75 million current generation video game consoles (Microsoft Xbox 360, Nintendo Wii, and Sony PlayStation 3) had been sold, meaning that many homes have two or more current generation game consoles

- We estimate that the total electricity consumption of video game consoles in the US was around 11 TWh in 2007 and 16 TWh in 2010 (approximately 1 % of US residential electricity consumption), an increase of almost 50 % in 3 years.

- The most effective energy-saving modification is incorporation of a default auto power down feature, which could reduce electricity consumption of game consoles by 75 % (10 TWh reduction of electricity in 2010).

- A simple improvement that could be implemented now via firmware updates to power the console down after 1 hour of inactivity. Though two of the three current generation consoles have this capability, it is not enabled by default, a modification that would be trivial for console manufacturers.

- Saving consumers over $1 billion annually in electricity bills.

 

Scott Lowe at The Verge points out that in May 2011, Microsoft did update Xbox 360′s firmware to enable auto-power-down by default. Now it’s up to the rest of industry to catch-up.

Life on Mars is possible – for cave dwellers

A study of the biology and geology of Mars, from the Australian National University, shows there is plenty of room for life on Mars.

Granted, much of that room is in caves just below the planet’s surface, and much of that life will likely be microbes rather than little green men. But here’s the kicker — fully 3% of Mars has the right conditions to support life, the researchers say.

…if you run the same numbers on Earth, just 1% of the planet’s volume can support life.

Mars’ surface is too cold and too low-pressure to support liquid water…But Lineweaver’s study looked at geological data from decades of Mars missions — and concluded that it would be warm and pressurized enough for life to live just below the surface. Warmth from the planet’s core provides the heat, and soil packed in from above creates the necessary air pressure.

So are there vast empires of microbes — or even something bigger — lurking just below that dusty red surface? We should know more next August when NASA’s Curiosity Rover arrives on Mars. This next-generation space robot comes equipped with a laser beam that can blast rocks, and a robotic arm that can examine the results.
