Computers get hot. Heat is bad for computers. To whisk it away, we use a combination of heatsinks and fans to snatch heat away from the internals and blast it out of the computer's case. But Sandia has a concept that combines the two in a way that, they claim, increases heat-removing efficiency by up to 30 times.
There’s a piece of equipment that’s slowly been making its way into restaurant kitchens: the blast chiller. It does exactly what it sounds like: cool things down quickly, using fast-moving cold air. This coming summer, LG is going to release a version of their refrigerator for home kitchens that incorporates a small blast chiller for quickly cooling down cans of soda and bottles of wine.
Japanese officials conceded today they might have to entomb the crippled Fukushima Daiichi nuclear plant in a sarcophagus of sand or concrete in order to contain the radiation. It’s a last resort, but acknowledging it’s possible is a sign that matters are still not improving at the stricken plant.
The joys of working from home are many -- peace, quiet, wear whatever you like -- but the greatest may be the cozy warmth of using a laptop in bed. Unfortunately, as the folds of the bedclothes impede the cooling airflow through the machine, it becomes hotter and hotter, to the detriment of the laptop and its surroundings.
Now, Intel is promising secret "pillow-proof" technology to prevent this overheating.
After one failed attempt to remove a broken cooling pump on Saturday, a second attempt has succeeded. In a seven-and-a-half-hour spacewalk, Doug Wheelock and Tracy Caldwell Dyson managed to unhook the ammonia line that was spewing frozen NH3 crystals last time, then pry off the broken pump with a grapple bar. Whew.
Whitening the world's roofs would offset the emissions of the world's cars for 20 years, according to a new study from Lawrence Berkeley National Laboratory.
Overall, installing lighter-colored roofs and pavement can cancel the heat effect of two years of global carbon dioxide emissions, Berkeley Lab says. It's the first roof-cooling study to use a global model to examine the issue.
Supercomputers and massive data centers carry huge energy costs when it comes to keeping their electronic components chilly. Now IBM is set to unveil its next big supercomputer, Aquasar, which keeps cool with a constant circulation of water at 140 to 160 degrees F, according to TechNewsDaily.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
