A team of researchers at the Ohio State University (OSU) successfully produced a dye-sensitized solar cell, which can store power by using air to decompose and re-form lithium peroxide. This device combines a solar cell and battery into one, and it is the first device of its kind. The adoption of this technology could also considerably lower the costs of solar cells.

A New Water Saving Showerhead

20141103153913-3-No-wasted-water

Making a home water efficient often comes down to they type of showerheads that are installed. To combat water waste when showering, a California-based company has come up with an innovative showerhead called Eva. This is a Bluetooth-connected showerhead, which works with any sized shower attachment, and the makers say it has the capability of cutting a home’s water consumption in half.

Discarded rubber tires may soon find a new use. A team of researchers from the US Department of Energy’s Oak Ridge National Laboratory have come up with a method of harvesting the carbon black from them, which can then be used to create anodes for lithium-ion batteries that provide power to plug-in electric vehicles and store energy produced by solar panels and wind turbines. According to the researchers, the new batteries will perform even better than the ones we use today.

MIT Researchers Develop A More Efficient Battery

mit_all_liquid_battery-2

The more widespread adoption of renewable sources of energy is at least in part hampered by our poor ability to store energy. But a team of MIT researchers has recently a made a breakthrough in developing a new battery system. This all-liquid battery system is more efficient at storing energy, and costs less to produce, than currently available solutions. The further development of this system and use could make solar and wind energy more attractive and therefore facilitate its wide scale adoption.

The technology for the 3D printing of homes is still in its infancy, but the idea has great potential in this world where population is growing, and adequate and sustainable housing is just not keeping up. Wasp is an Italian firm that recently developed a 3D printer that can create affordable homes using mud as the main ingredient. Given the freely available and nearly limitless nature of mud, such a tech shows great promise.

Getting Energy and Clean Water From the Clouds

main

A team of scientists is currently raising funds through a crowd funding campaign to develop Air HES (HydroElectric Station), which is basically an airship that can extract clean water and electricity from the clouds. More specifically, it does so by harvesting and condensing water vapor, and uses it to spin up an electric turbine generator to create power. The developers have already built a small prototype to test the device and have done feasibility studies, while the main aim of the funding campaign is scaling up the device to produce economically viable levels of water and power.
