Nearly 30 years ago (May 6, 1979), U.S. President Jimmy Carter made the following prophetic statement at the inauguration of a solar-thermal water heater installed on the White House roof: "In the year 2000, the solar heater behind me will still be here, supplying cheap, efficient energy. A generation from now, this solar heater can either be a curiosity, a museum piece, an example of a road not...

Fuel cells and hydrogen economy are inevitably used in the same breath when talking about clean power and ways to wean us from our addiction to carbon-based fuels. That’s because H2 -based fuel cells make electricity and heat with only water in the exhaust. Unfortunately, realistic assessments of the current situation conclude that it will be awhile — perhaps decades — before hydrogen...

The Seebeck effect — the direct conversion of a temperature difference to electricity — is responsible for the operation of thermocouples. But taking advantage of this phenomenon to make electricity from waste heat in so-called thermoelectric (TE) devices has been hindered by the high cost or toxicity of common TE materials, such as lead-tellurium or cobalt-antimony. And up to now, production...

Daihatsu Motor Co., Ltd. (Osaka, Japan; edlinks.che.com/7369-532) has designed a fuel cell for powering automobiles, using nickel and cobalt for the electrodes (instead of conventional platinum and carbon), and hydrazine hydrate (N 2H4. H2O) as its fuel (instead of hydrogen). Although hydrazine is a hazardous material, the company says the hazard level is about the same as gasoline. And unlike H2, which...

Traditionally, the cogeneration of steam and electricity has been restricted to plants that generate superheated steam, making the recovery of energy losses from saturated steam impossible for many industrial sites ranging from distilleries to pharmaceutical plants and pulp-and-paper mills. At the Chem Show (see first item above), Pennant International Corp. (Edison, N.J.; edlinks.che.com/6902-538)...
