TRIADELPHIA - As energy costs continue heading upward, Touchstone Research Laboratory may have the answer to reducing America's dependence on foreign oil: algae.
Triadelphia-based Touchstone is heading in a new direction by working with a U.S. Department of Energy program for Advancements in Sustainable Algal Production.
The goal of the energy department's program is to have test beds across the country growing algae in different environments to understand how various new technologies perform in those different environments. The department's research institutes will have access to facilities and data from long-term algal cultivation trials for use in establishing a realistic and coherent state of technology for algal biofuels.

"When you go back far enough, all oil came from organisms that consumed carbon dioxide. This is what we are now doing with the algae," Brian Joseph, president and chief executive officer of Touchstone, said.
"We need to find algae that make more oil. We are about two or three breakthroughs away from making this commercially viable," he added.
Touchstone's algae-growing facility in Wooster, Ohio, includes a laboratory and four large-scale growing ponds that are 180 feet in length. Two of the algae ponds are in greenhouses while two are outside. The facility takes waste carbon dioxide from a fluidized bed furnace located at the site and uses it to grow the algae.
In addition to the algae programs, Touchstone has invented new aluminum alloys, new steel products, and helped to qualify new materials for windmills and jet engines. The company also has invented new ways to produce carbon fiber aircraft parts. Joseph said the company has solved thousands of manufacturing problems for almost any industry.
One of Touchstone's most famous products is CFOAM. The coal-based material is a lightweight, fire-resistant and impact-absorbing structural carbon foam. It can be fabricated in a variety of shapes, sizes and densities. CFOAM replaces conventional materials that are heavier and higher in cost while providing greater structural capability.
"Coal gets bashed by a lot of people, but it has a lot of useful applications, many of which have nothing to do with burning it," Joseph said.
Another Touchstone item is CSTONE, which stands for carbon stone. This is also a coal-based product that has been tested in various defense applications, including landing pads, missile tubes and rocket nozzles.
"Touchstone is entering a new era with new technologies, new products and new services. To handle this growth, Touchstone is now looking to hire additional engineers and scientists to manage programs and invent new things," Joseph added.
