Technology breakthrough fuels laptops and phones

| 24/02/2011

(Power online): SiGNa Chemistry Inc. has unveiled its new hydrogen cartridges, which provide energy to fuel cells designed to recharge cell phones, laptops and GPS units. The green power source is geared toward outdoor enthusiasts as well as residents of the Third World, where electricity in homes is considered a luxury. "SiGNa has created an inherently safe solution to produce electric power, resulting in an eco-friendly and cost-effective portable solution," said Michael Lefenfeld, SiGNa’s CEO. The spark for this groundbreaking technology came from the laboratory of James Dye, SiGNa’s co-founder and University Distinguished Professor of Chemistry Emeritus at MSU.

His work with alkali metals led to a green process to harness the power of sodium silicide, which is the source for SiGNa’s new product.
