This technology can be used to alleviate communication equipment power failures in first responder applications. The device possesses a longer operation period than similar devices currently powered by batteries. This technology employs low cost raw materials such as sand and lime to rapidly and safely generate hydrogen on demand. More than half of the hydrogen liberated by the chemical reaction is obtained from water which is the co-reactant. The water need not be pure and in fact can be brackish water salt water or urine. An environmentally benign by-product (siloxane/silicate) is formed eliminating the need to transport the by-products to a regeneration facility. None of these processes release carbon dioxide (or any other gaseous pollutants) and the thermal signature is less than that of sodium borohydride or reformed fuel systems thereby making them ideal for both personal and military applications. Applications: To alleviate communication equipment power failures in first responder applications.
