Clean Hydrogen Production for 200 Hours

By Kate S. Scientists at Stanford University have just built a low-cost water splitter that uses a single catalyst to produce both hydrogen and oxygen gas. This is an invention that could pave the way for a boom in production of clean-burning cars. The scientists say that their device, which can run nonstop for an unprecedented period of time, could provide a renewable source of clean-burning hydrogen fuel for transportation and industry. The team used lithium-ion battery technology to create one low-cost catalyst that is capable of driving the entire…

Turning Evaporation into Electricity

By Kate S. The power of water has long been harnessed by humanity, but one part of the water cycle — evaporation — has been overlooked until now. Many scientists are experimenting with improved solar cells and biofuels, but Columbia University scientists have a new, noteworthy idea. They have announced the development of a novel device that turns evaporation into electricity. In fact, the small prototype generates enough electricity to power a lightbulb and the rotary engine that drives a miniature car. Energy from Evaporation When evaporation energy is scaled…

Stay Tuned for Low-cost, Smart Windows

By Kate S. Today, the University of Cincinnati announced that, together with industry partners, they’ve invented new ‘smart window’ shade technology that could improve upon existing windows and blinds. The researchers say that this patent-pending research will lead to low-cost window tinting that dynamically adapts for brightness, color, and opacity. The new tech is designed to provide privacy while allowing light in. A collaboration between the University of Cincinnati, Hewlett Packard, and EMD/Merck Research Labs has resulted in a patent-pending product that the team is calling ‘tunable’ window tinting. The…

Off-Grid Tiny House Will Blow Your Mind

By Kate S. This is not the set of a sci-fi show. It is the Ecocapsule, an independent off-the-grid micro house from Nice Architects, an architectural studio in Bratislava, Slovakia. The Ecocapsule has been in development since 2008. Recently, a prototype went on display for the first time at the Pioneers Festival in Vienna, Austria, and EH Science invited the architects to talk about their egg-shaped creation. “With its off-grid life span, portability, and flexibility, it is suitable for a wide range of applications–from an independent research station or a…
