A new revolutionary glass technology is said to be so thin and flexible it can be used to wrap food, but is so strong that it withstands more pressure than steel. It is reportedly a pollution-free glass battery with an endless life and with up to 30 times more energy than a conventional lead-acid battery of the same size and weight. A team of American and Russian scientists patented the glass-like material under the trademark Dynaglass. Produced through a process designated the depletion process, Dynaglass offers the potential to inexpensively market a variety of structural and electrical products.

Patented by Dynelec Corp., a Columbus, OH technology company founded by a small group of U.S. entrepreneurs and international scientists, Dynaglass has been under development during the last 7 years in Russia and the U.S.

"It will be the enabling technology for many, many products," said Roy Baldwin, president and CEO of the company. "There are thousands of uses for this."

Along with the strongest glass ever invented, experiments indicate that a glass battery under development by Dynelec, named the Dynaglass Battery, can be produced in a wide range of sizes to meet different applications. Advantages of the glass battery include an energy storage capacity that is 5- to 30-times greater than a conventional lead-acid battery and unlimited recharging cycles. In addition, it is said to be inexpensive to produce, lightweight, environmentally safe, and requires little or no maintenance.

"It's very attractive to pursue a battery that has no chemical in it," Mr. Baldwin said. "You can get rid of sulfuric acid, lead, and all the negative characteristics of a normal battery. As far as we know, it's rechargeable through an infinite number of cycles.

"There is still a considerable amount of development work to do before we put a battery on the table and say, 'Here it is,' but the development of the glass is essentially complete," Mr. Baldwin said.

In an independent analysis of the energy storage in Dynaglass, Dr. Keith D. Keefer, who owns an engineering consulting firm near Seattle, WA, said, "The key practical and commercially valuable aspect of the glass battery is its potential for enormous energy and power density."

The company is now seeking a strategic alliance with an established glass-making corporation to construct a research and development center and a pilot plant for the production of 1 ton per day of Dynaglass.

"The scientists believe that the technology for manufacture of Dynaglass is proven to the point where we can complete negotiations with companies in the glass production industry," Mr. Baldwin said. "It makes sense for a glass producer to adopt structural Dynaglass production with a very real chance of entering the energy industry at practically no additional cost."
