New Geoengineering Approaches Offset Global Warming More Efficiently

Releasing engineered nano-sized disks or sulphuric acid, a condensable vapour, above the Earth are two novel approaches that offer advantages over simply putting sulphur dioxide gas into the atmosphere, says Dr. David Keith, a University of Calgary climate scientist.

Microwave Plasma Hydrogen Recovery System

A microwave plasma reactor was developed for the recovery of hydrogen contained within waste methane produced by Carbon Dioxide Reduction Assembly (CRA), which reclaims oxygen from carbon dioxide. NASA can incorporate the innovation into flight hardware systems for deployment in support of future long-duration exploration objectives.

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.

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.
