It seems we’ve been underestimating the power of plastic. After the material was repurposed into makeshift lamps in the Philippines, it’s proving there is little it can’t do. Grey Dhaka in Bangladesh is taking plastic to new limits with a plastic bottle air conditioner that is completely electricity-free.
Repurposed plastic bottles are cut in half and mounted on a board or a grid in accordance with the window size with the bottlenecks facing the inside of the house. The board is then installed on the window… Hot air enters the open end of the bottle and is compressed at the neck of the bottle, turning the air cooler before it is released inside the house.
The device, called the Eco-Cooler, can reduce indoor temperatures by up to 5 degrees Celsius. Correct me if I’m wrong, but I think regular-running electric air conditioners may now be facing a promising contender.
Today, more than 25,000 households have an Eco-Cooler in their homes. It has been installed in places such as Nilphamari, Daulatdia, Paturia, Modonhati and Khaleya.
Inventor Ashis Paul claims his daughter’s physics tutor inspired the Eco-Cooler. If simple DIY projects can combat climate change at no cost, maybe kids should reconsider paying attention in class.
The era of Energizer batteries has climaxed. Nowadays, the electrochemical cells are powered by unusual sources, spit included. Other new devices don’t even need them. At any rate, updated technology can’t phase them out entirely — so inventor group Ossia has paved middle ground. The solution? A battery that only requires air to charge.
[Ossia’s Cota] transmitter broadcasts a directed and concentrated RF signal towards a given device in a room, which is absorbed by the gadget’s own RF antennas inside, and turned into usable power.
Alas, for gadgets such as iPhones and Fitbits, RF antennas will have to be external. But, as tech circles are, Ossia has an alternative up its sleeve: the Cota Forever Battery.
Featuring the exact same size, form factor, and power output of a traditional AA battery, it can be inserted into a battery-powered device to instantly and easily make it compatible with Cota wireless power transmitters.
Ever dream of never having to switch out obnoxious television remote batteries? It may be time to wake up — the future’s just arrived!
To salvage deteriorating resources, nations worldwide are setting ambitious eco-goals in a short span of time. By 2012, Costa Rica hopes to phase out single-use plastic products. For the first time in 70 years, Kazakhstan is reintroducing wild tigers into its cat-barren jungles. Not to be left out of the loop, St. Louis is swearing off fossil fuels in an attempt to go fully renewable by 2035.
“It can be a win-win for everyone. We can protect health. We can improve air, we can improve water. We can address climate change. We can save people money on their bills. Why wouldn’t we be moving in that direction?” said [Sara Edgar of Sierra Club.]
St. Louis is among just over 40 cities that have pledged to rely solely on wind and solar energy. For decades, the city has remained a top contributor to health issues caused by smog. It’s now clear that its local government is hoping to make a more positive name for the tourist spot.
“Some of the things that Donald Trump has done since he became commander in chief just goes against everything that I stand [for], that the people of St. Louis stand for,” [said St. Louis President Lewis Reed.]
Yikes. Trump better watch his back — it’s obvious St. Louis isn’t rolling back on its own environmental safeguards!
