A Way to Make Motor Fuel Out of Wood? Add Water

A Georgia company says it has overcome a major roadblock in turning agricultural waste into vehicle fuel and other useful chemicals by experimenting with a technology that treats the waste with compressed water heated to very high temperatures.
The company, Renmatix, plans to cut the ribbon on a research and development center on Tuesday in King of Prussia, Pa., near the heart of the nation's chemical and refining industry, to complete development of the process. The goal is to accomplish something that has eluded a dozen companies in recent years despite big government inducements: to commercialize a technology for making use of cellulosic biomass, or wood chips, switchgrass and the nonedible parts of crops.
If it works, the technology could reduce the nationís reliance on oil imports for gasoline in favor of a cleaner-burning and less expensive source of energy. A company with a workable technology would have a guaranteed market, given that Congress has set quotas for the consumption of cellulosic fuel but so far, hardly any is being produced.

VIDEO: How Hair Ice Grows
In 2013, American Scientist featured an article on odd ice formations on plant stems, including these curling ribbons of ice. One of the types of ice discussed in the article was hair ice—long, thin strands of ice that grow under quite specific conditions. The only problem is that a new study shows the theory put forth at the time—that gas pressure pushes the water out—isn’t correct... (click the link above to read more).
