The liquid chimney is claimed to be a unique solution to the problem posed by the CO2-laden exhaust created by coal and natural gas furnaces, which together account for about half of America’s greenhouse gas emissions. The basic technology for liquid chimneys - so called because the exhaust from a power plant is filtered through an alkaline scubber - has been around for decades.
Invented by Fremont, Ohio resident Tom Kiser, shown left, a heating and ventilation engineer turned entrepreneur whose biggest claim to fame is his work on the Ford Motor Company’s famed ecologically designed Rouge River Complex, the liquid chimney could be one of the key solutions in the effort to halt climate change. If it works on a commercial scale, it could lead to a dramatic reduction in global CO2 emissions.
Kiser is working on making his patent pending system more efficient and believes that he is close to a working model that could be retrofitted to existing industrial furnaces or boilers that run on natural gas. Eventually he hopes to get the technology to work with any fossil fuel, including coal. What makes the system more economical is that the chimney captures wasted heat, which boosts the efficiency of the system and saves on fuel costs.
