Packing Peanuts Could be Recycled Into More Sustainable Batteries

Foam_Peanuts

Building better and more sustainable batteries is certainly one of the goals for the future. And now, those packing peanuts used to protect fragile things from breaking during transport could play a major role in achieving this goal. A team of researchers at Perdue University has discovered that these packing peanuts could actually be used in lithium-ion batteries.

Energy Harvesting Tree for the Home

tree

In January 2015, the Finnish VTT Technical Centre introduced decorative organic photovoltaic cells (OPV), which can be inexpensively mass-produced, and which can easily be incorporated into the design of any home. These cells are capable of capturing energy from interior lighting and generate enough power to run small devices and sensors.

Pretty Solar Panels and Harvesting Energy From Interior Lights

deco

Finding and using alternative energy sources is quickly becoming a must and one obstacle to overcome is how to make solar panels easier to incorporate into building projects. This, of course, involves making them look pretty. VTT Technical Centre of Finland has gone a step further in this. They have come up with a method that allows for the printing of decorative graphics and functional components onto flexible organic solar panels.

Harvesting Drinking Water from the Air

ext

A new Kickstarter campaign is aiming to raise funds to build a device, which will be capable of harvesting safe drinking water from the air. The Warka Water, as it is called is an off-the-grid bamboo tower, which could, according to the developers, collect an annual average of 26.4 US gallons of water per day. This would make it ideal for deployment in undeveloped regions of Africa and elsewhere, which is what they are planning on doing.

Solar Powered Wakati Keeps Veggies and Fruits From Spoiling

ext

Wakati is an innovative little machine, which is capable of providing sterilized storage for fruit and vegetables, keeping them from spoiling in hot climates. This product is aimed at farmers in developing countries who do not have regular access to electricity and therefore refrigerators, meaning that a large portion of the food they produce goes to waste. To fight this problem, the Wakati is capable of operating on solar power.
