Solar-Powered, Oil-Cleaning Robots: Solution for Oil Spill?

A team of researchers at MIT's SENSEable City Laboratory have developed Seaswarm, a robot that autonomously navigates the water’s surface and uses nanofibers to absorb 20 times its weight in oil, which could be made into a viable solution for cleaning up the Gulf oil spill.

Paving Slabs Clean the Air

Innovative paving slabs that are coated in titanium dioxide nanoparticles can reduce the amount of nitrogen oxide in the air. Titanium dioxide is a photocatalyst; it uses sunlight to accelerate a naturally occurring chemical reaction, the speed of which changes with exposure to light.

Open Software Platform Helps Save Energy

Starting in 2011, energy suppliers in Germany will be required to offer electricity at variable rates under the German Energy Act. A new energy management software platform will enable customers to opt for flexible electricity rates, so that they can purchase power at times when it is available more cheaply. Another advantage is better utilization of the power grid.

Sustainable Biochar to Mitigate Climate Change

By producing biochar - a charcoal-like substance made from plants and other organic materials - up to 12 percent of the world's human-caused greenhouse gas emissions could be sustainably offset, which is more than what could be offset if the same plants and materials were burned to generate energy.

Making Hydrogen From Waste Vegetable Oil

Researchers at the University of Leeds have found an energy-efficient way to make hydrogen out of used vegetable oils discarded by restaurants and other establishments. The process generates some of the energy needed to make the hydrogen gas itself and is also essentially carbon-neutral.
