  • Study says wind turbines raise surrounding area temperature, but only at night

    Who said the butterfly effect couldn't apply to renewable energy? Though wind farms are considered pretty green on the energy-generating spectrum, it looks like they, too, have an impact on the planet. According to a study published today in the journal Nature Climate Change, turbines can raise the local temperature -- albeit slightly. From 2003 to 2011, researchers monitored satellite data for west-central Texas, which is home to 2,350-plus turbines and four of the world's largest wind farms. In that decade, scientists observed a temperature increase of 0.72 degrees in wind farm regions compared to areas without turbines. That warming trend was especially marked at night, when the temperature difference between the ground and the air is highest. The temperature increase was also higher in winter; researchers say that these cooler, windier conditions cause turbines to generate more electricity and therefore create more heat. Since the study didn't find any change in daytime temperatures, it looks like we don't have to ring the global warming alarm just yet.

  • iPod fathers unveil their next project, the Nest Learning Thermostat (hands-on)

    Over the summer, we got word that a couple of unnamed ex-Apple engineers were getting ready to unveil an unnamed product, under the guise of an unnamed startup. As it turns out, that startup was Nest Labs, and those Apple alums were none other than Tony Fadell, longtime SVP of Apple's iPod division, and lead engineer Matt Rogers. And yes, the product they had to share makes fine use of a click wheel. But if you thought they'd be cooking up a next-gen music player, you'd be wrong. Instead, the pair have been designing a thermostat, of all things, dubbed the Nest. In addition to being the most stylish model ever to grace a dining room wall, it promises the kind of intelligence we've come to expect in other household appliances -- just not thermostats, per se. It'll go on sale next month for $249 in places like Best Buy, but we managed to snag an early sneak peek. Find some photos below and when you're done, join us past the break where we'll explain how it works. %Gallery-137451% %Gallery-137452%

  • LG prepares to update Optimus 2X, banishes unexpected reboots to Never Never Land

    LG is delivering good news for those affected by random reboots and shutdowns on the Optimus 2X. Today, the company reached out to Engadget and acknowledged the plight of its early adopters. Even better, the manufacturer wants everyone to know it will begin delivering updates in Europe this week, and expects North America to be close behind. In most situations, users will receive the firmware update over-the-air, but this will depend on your carrier and region. After all the hoopla, LG determined these troubles occur when the device is charging, the power button is pressed, or the phone is in standby -- which basically means whenever you reach for it. Let's hope this update filters down to G2x handsets as well. It would seem rather unkind to leave them in the cold, don't you think?

  • Core i7-equipped MacBook Pro CPU hits 100 degrees Celsius (updated)

    Hydrocarbon fuel cell? 600 degrees Celsius. Large Hadron Collider? -271 degrees. Microwave drill? 2,000. Your run of the mill Core i7 MacBook Pro can't compete with these extreme temperatures, but that doesn't mean it can't get pretty darn warm under pressure. PC Authority recently put the latest edition of Apple's sleek silver classic through a series of torture tests, and found that running Cinebench could cause the CPU temperature to climb over 100 degrees Celsius. The metal shell proved ineffective at dissipating the heat as well as the similarly equipped Fujitsu Lifebook SH760, which finished the same test at 81 degrees, and actually required PC Authority to run the MacBook Pro on its side (see pic above) to complete certain tests. The site thinks that Apple's cooling solution may be inadequate for a Core i7, but these results could be a fluke -- in our experience with the machine, we actually noticed an improvement over the egg-cooking solutions of yesteryear. Update: We'd like to point out that the temperatures described were related to the CPU internally, and not the actual case of the laptop.

  • Fujitsu's 2.5-inch MHW2040AC HDD doesn't sweat extreme temperatures

    Continuing on the path of kicking out a large variety of hard drives over the course of a couple months, Fujitsu is at it once again, and this time its the MHW2040AC getting the spotlight. The RoHS-compliant HDD looks like your everyday hard disc drive upon initial inspection, but underneath its sly facade lies an ability to function in temperatures ranging from 30 below to 85-degrees (read: near face-melting heat) Celsius. As expected, the drive is being marketed as a rugged alternative for automotive / marine uses, where the internal storage is likely to face extreme temperatures from time to time. Additionally, it can reportedly withstand "operational shock of up to 300G" while requiring just 1.8-watts of power to read and write data. No word just yet on how much this temperature resisting beast will run you, nor if it'll ever arrive in sizes other than 40GB, but if you're planning a relocation to Moscow or Death Valley Phoenix, the pricetag isn't likely to matter.[Via AkihabaraNews]
