Active solar hot water systems water are usable with air, liquid, vapor or liquid collector fluid or gas to liquid process. Hot water production with an air-heating collector’s distribution for heating is usually performed in the large space heating panel systems. The losses in the process of heat transfer are high. Air systems work not as well as units of the liquid to heat the water. Air systems are generally only capable of hot water 70 to 95F. (more…)

Fuel cells are direct energy conversion devices that combine two reactants to produce electrical power. The reactants are typically a fuel such as hydrogen fuel cells, or methanol, and oxygen from the air. Fuel cells require an electrolyte capable of passing an ionic charge carrier across an electronic conduction barrier where the ions are driven by a concentration gradient. Fuel cells also need a catalytic-based anode and cathode for reactant preparation. For mesoscale/ microscale systems, fuel cells are best fabricated in thin film form. Depending on the desired power output of the system, the ‘‘footprint’’ may well be relatively large to supply the required power. (more…)
