“We think we will have fourth-generation fuels in about 18 months, with CO2 as the fuel stock.” Simple organisms can be genetically re-engineered to produce vaccines or octane-based fuels as waste, according to Venter. Biofuel alternatives to oil are third-generation. The next step is life forms that feed on CO2 and give off fuel such … Read more

Several years ago, SunPower, a unit of Cypress Semiconductor, (CY) realized the top metal plate was reflecting the sun’s rays, cutting efficiency by reducing the percentage of sunlight converted to electricity. So the company decided to put both plates beneath the silicon. It now has an industry-high efficiency of 22% vs. an average of 16%, … Read more
It is a battery that looks like a piece of paper and can be bent or twisted, trimmed with scissors or molded into any shape needed. While the battery is only a prototype a few inches (centimeters) square right now, U.S. researchers at Rensselaer Polytechnic Institute who developed it have high hopes for it in … Read more

So-called ‘second generation’ biofuels – made from lignocellulosic feedstocks like straw, grasses and wood – have long been touted as the successor to today’s grain ethanol, but until now the technology has been considered too expensive to compete. However, recent increases in grain prices mean that production costs are now similar for grain ethanol and … Read more
The typical Western diet may be more than just hazardous to the health of patients treated for colon cancer. New research suggests it may be deadly. Former patients in the study who ate the most red and processed meats, refined grains, fats, and sugars were about three times as likely to die or have their … Read more
