MIT scientists and engineers have a new twist on phase-changing renewable technology. It combines the most efficient generation of solar steam to date by our favorite energy machine, the sun, and a new graphite-based collection system. This method puts out the lowest optical concentration reported thus far: steam generation at an intensity about 10 times that of a sunny day.

Experts from Sheffield Universitys Department of Physics and Astronomy and Department of Chemical and Biological Engineering have previously used the spray-painting method to produce solar cells using organic semiconductors – but using perovskite is a major step forward. Efficient organometal halide perovskite based photovoltaics were first demonstrated in 2012. They are now a promising new material for solar cells as

The material could allow more utilities to store large amounts of renewable energy and make power system more reliable and resilient. The new electrode enables sodium-beta batteries to last longer, helps streamline their manufacturing process and reduces the risk of accidental fire. “Running at lower temperatures can make a big difference for sodium-beta batteries and may enable batteries to store

RESEARCHERS from Stanford have successfully used a pure lithium anode in a lithium ion battery. The common lithium-ion batteries of today tend to use an anode made of graphite or silicon, with the lithium only used in the electrolyte. While a lithium anode could boost the capacity by four fold and lower the weight of lithium ion batteries, researchers were
