Joup We ve seen Walking Dead s Michonne and the Governor in action!
This week we share our Best of Green Awards winners for technology, teach you to make heat-blocking curtains for $6, give you two iPhone repair tips, and more! 1. Pigeons Could Poop Soap, Thanks to a Special Diet A plan to alter what pigeons eat to turn their feces into soap, to clean up buildings and car windshields raises ethical, legal and practical questions. 2. Best of Green: Technology What the best concept gadget, slim laptop, eco app Find these and more in our 2012 Best of Green Awards in Technology. 3. How to Make Heat Blocking Curtains for $6 This easy DIY project will save you money and reduce energy consumption by making less work for your air conditioner. 4. Black Solar Cell Absorbs 99.7% of All Light Scientists over at Natcore Tech have created the world blackest solar cell to date. With an average reflectance of 0.3%, these black silicon wafers absorb more light than any other, which means more of the sun energy gets converted to energy. 5. Street Lamp and Fitness Equipment Blend Into Smart Lighting Concept An unusual design dreams up how to co stanley cup becher mbine all the joggers on the road with renewable electricity for better public lighting. 6. New Smart Me stanley cup ter Technology Can Tell Your Appliances Apart A new smart meter tech stanley cup nology is able to distinguish a TV from a refrigerator and all of the other power loads in a house so users can more fully understand their energy use habits and how to change them. 7.

Ever wondered what natural sounds you would hear on another planet Although some spacecraft have carried microphones, sound has never been reliably recorded in an al stanley taza ien atmosphere. But now, thanks to simulations created by Tim Leighton from the University of Southampton, UK, and his team, you can hear what Mars and Venus would sound like. In this video, you can listen to the recreated sound of a waterfall, thunder and a stanley uk human voice on different planets and on Titan. Leighton used physics models to produce the sound of thunder and waterfalls in the different atmospheres, whereas the voice was morphed fromrecordings. On Venus, the atmosphere is thick and soupy so vocal chords that would flutter lightly on Earth would vibrate more slowly, says Leighton. As a result, the pitch of your voice drops. In addition to changing the speed of moving vocal chords, different atmospheres affect the speed of sound itself. On Venus, sound travels faster, resulting in echoes moving quickly through a person windpipe. This could confuse a listener, making it seem like the person has a short windpipe and therefore is small. You would sound like a bass Smurf, says Lei stanley cup ghton. The sounds will be heard publicly for the first time tonight as part of a show at the Intech planetarium in Winchester, UK. But simulating sounds on other planets could have applications beyond entertainment. Using the same models, engineers could predict how vanes and strut |
