Nodules: Nineties & Beyond

Manganese nodules, as metal ores, have for the most part been cast aside from further consideration within this century. However, in the decade of the 90s, rising demand at all levels of society, for clean air give nodules a new - lease on life as a stack gas cleaning agent. Further, the Clean Air act of 1990, mandates enormous outlays to bring systems into compliance with new stringent standards. Quick corrective actions are imperative. Research beginning in the 1960s proved nodules possess unique qualities to remove acid compounds from stack gases. Early this year, the National Science Foundation awarded General Electric an $83 million contract to design a system to extract oxides of sulfur and nitrogen from coal fired power plants. Environmental damage is abundantly evident on the ground, from the air as well as form space. A dirty pall of yellow-brown smog is smothering both animal as well as plant life around the globe. Losses run into billions!
