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.

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.

Spray On Solar Cells

cells

A team of researchers at the University of Sheffield in the UK have found a way to make a spray-on solar cell, which has perovskite as the light-absorbing layer. This new cell’s efficiency is only 11 percent, but it can be produced very cheaply, which could be the first step forward in large scale production of affordable solar panels.

Plants, just like humans and animals, have a way of communicating with each other. Their language is comprised of electrical signals, through which they send messages to other plants. And now an international group of scientists is developing a way to analyze these electrical signals, and translate them into information we can understand. The project is called PLEASED (PLants Employed As SEnsing Devices) and has already received €1.07 million ($1.46 million) in EU funding.

When looking into off-the-grid heating and power sources for the home, those interested might soon be getting a new option. The Dresden, Germany-based Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) has joined forces with the heater manufacturer Vaillant and together they have come up with a domestic fuel cell system, which uses natural gas to produce both heat and electricity.

Researchers at Northwestern University have developed a new solar cell that uses tin instead of lead perovskite as a collector of solar energy. This cheap and environmentally-friendly solar cell can therefore be made without any high-tech equipment or hazardous materials.
