The polymer components of these composites are traditionally made using oleo-polymers; however, an alternative is to use natural and renewable sources as soybean oil, linseed oil, sunflower oil, etc. This is because the carbon black can be used as filler material and can beneficially modify the electrical and mechanical properties of the used matrixes. Polymers derived from those natural oils can be tailored for engineering and aeronautical applications by reinforcing them with natural and...

The net environmental benefit of biofuels is a matter of constant debate, in part because scientists and government leaders continue to discover new ways to maximize the industrys benefits while avoiding damage to the environment. Pipe the carbon dioxide from the plants to seas and pump it into deep-sea sediments that would trap the gas, taking it out of the global-warming equation, Hansen said. Making and burning biofuels emits less greenhouse gas than burning regular gasoline, but only...
