Sugar-powered Cars run on Hydrogen

hydrogenGreen fuels are a really hot topic, with every single day bringing a new (claimed) discovery or breakthrough, but many of them are just minor improvements. Still, every once in a while you hear about something that sounds really promising (like green gasoline). Now it seems that chemists are describing development of a “revolutionary” process for converting plant sugars into hydrogen.

This process could be used to cheaply and efficiently power vehicles equipped with hydrogen fuel cells without producing any pollutants. The process itself is really not that complex too; it involves combining plant sugars, water, and a cocktail of powerful enzymes to produce hydrogen and carbon dioxide under mild reaction conditions. This new research could just be the step forward that the “hydrogen economy” needed, despite the fact that many were claiming that it has no future.

Here’s what lead researcher Y.-H. Percival Zhang, Ph.D., a biochemical engineer at Virginia Tech in Blacksburg, Va. had to say:

“This is revolutionary work! This has opened up a whole new direction in hydrogen research. With technology improvement, sugar-powered vehicles could come true eventually.”

While hydrogen is recognized as a clean, sustainable alternative to fossil fuels, its production is considered to be expensive and inefficient at the time. But now, Zhang and his colleagues claim they have found the most promising hydrogen-producing system to date from plant biomass.

GeoPicture of the week: Biggest crystals in the world

Known as Cueva de los Cristales (Cave of Crystals), this hidden chamber in Mexico holds some of the largest natural crystals ever discovered. The translucent pillars, some as long as telephone poles and as wide as tree trunks, make for an eerie underground landscape, seemingly crafted by giants. But there’s no magic involved, just some […]

Pee-back time: Anti-Pee Paint Splashes Back at Public Urination

When man piss in wind, wind piss back, a modern Confucius states. In this line, the city of Hamburg ingeniously sought to address its growing public urination problem in the city's busy party center by painting walls with hydrophobic paint. Next time an unsuspecting person wants to take a load off in Hamburg's St. Pauli neighborhood, he might be in for a surprise - it'll splash back at him.
