Can a Homemade Air Conditioner Keep You Cool? All you need to make this DIY spot cooler is a bucket, some PVC pipe, a fan, and ice Forget the cute cats and the mom in the Chewbacca mask. One of the most riveting videos on YouTube is about making a homemade air conditioner—also called a bucket air cooler—out of a bucket, a fan, and some ice. In the video, which is approaching 12 million views as of late-May 2016, the DIYer who goes by the screen name desertsun02 barely breaks a sweat as he fashions a homemade air conditioner. So at Consumer Reports we just had to try it ourselves, including making our own video. Chris Regan, who leads Consumer Reports' A/C testing, built two versions of the homemade air conditioner—one from a bucket and one from a Styrofoam cooler—for less than $30 (not including the ice). You can see him at work in the video above, but basically the job entailed cutting a few big round holes in the side and top of the cooler and bucket, inserting PVC pipe (or some plastic cups), adding ice, and blowing air down through the top and out the sides with a small fan.

But building the homemade air conditioner was just the beginning. best air purifier 2011Chris then put both devices through our comfort test in the same chamber we use for our regular window air conditioner tests.fresh air cleaning llc buffalo After multiple runs using 8 to 12 pounds of three different forms of ice—cubes, reusable ice packs, and a frozen gallon jug of water—the homemade air conditioner was able to lower the temperature of a small room by only 2° to 3° F, and within 30 minutes the room temperature began to rise again.georgia clean air force certification The frozen jug of water was the best for cooling, apparently because it allows enough air to circulate around the jug to sufficiently cool it.

And while the ice cubes initially produced the lowest air temperature, once they started melting the temperature measured outside the duct (pipe or cup) wasn’t much different than the room temperature. Again, the room temperature began to rise in 30 minutes. Our take: Unless you want to try this DIY homemade air conditioner project for fun, you can cool off just by sitting in front of a fan and forget the bucket and the ice. If you need a whole-house cooling system, check our buying guide and exclusive brand reliability information for central air conditioners. While you’ll have to spend more than $30 for a new window air conditioner to keep you cool, we found some bargains in our recent tests starting as low as $125. Our three recommended small window units, which can cool 100 to 300 square feet, include the: GE AEM05LV, $170 (a CR Best Buy)If you need to cool a medium-size space like a master bedroom, consider one of these two GEs: the GE AEM08LT, $260, and the GE AEW08LV, $250.

Need one larger still for your family room? Our CR Best Buy is the LG LW1216ER, $350. And if you don’t mind a little noise, consider the Haier HWE12XCR, $310. Current Air conditioner ratings If you want to get a small taste for what it would be like to have Static’s superpowers, but only have five bucks—and no desire to be doused in strange chemical gases that cause mutations in people—then bang, baby! the gadget built in the above video is for you. Created by YouTube tinkerer and educator, NightHawkInLight (a.k.a. Ben), the DIY “static electricity generator” is essentially a retooled USB ionic air purifier, which, when connected to your skin and the surface you’re standing on, will allow you to make stuff like water and sand dance. Original USB Ionic Air Purifier, which costs about five dollars. The finished product, which runs on about 5 volts of electricity from three button cell batteries. This ever-so-slightly-super power is achieved by ionizing your skin’s atoms, giving them a negative electric charge.

And when your negatively charged atoms come into contact with something else that is either positively or negatively charged, you will either repel or attract it; thus the dancing of sand or the bending of water as seen in NightHawkInLight’s video. Air purifiers actually work in a similar way, by using either a negatively or positively charged electrode to pull oppositely charged airborne particles out of the air. Which means, maybe there’s room for a new DC superhero… like Purifiero! Or maybe this is just a cool way to freak out your friends with a little bit of the ol’ science. What do you think about NightHawkInLight’s static electricity generator? Are you ready to try this build for yourself, or are you shocked at the very idea? Let us know in the comments section below!

This software can recognise unseen events in YouTube videos Updated: Jun 24, 2016 15:16 IST Using deep learning techniques, a group of researchers has trained a computer to recognise events in videos on YouTube -- even the ones the software has never seen before like riding a horse, baking cookies or eating at a restaurant. Researchers from Disney Research and Shanghai’s Fudan University used both scene and object features from the video and enabled link between these visual elements and each type of event to be automatically determined by a machine-learning architecture known as neural network. “Notably, this approach not only works better than other methods in recognising events in videos, but is significantly better at identifying events that the computer programme has never or rarely encountered previously,” said Leonid Sigal, senior research scientist at Disney Research.
