A LIVING filter made of algae from the hot springs in Yellowstone National
Park could slash carbon dioxide emissions from power stations, according to
engineers at Ohio University.
A team led by David Bayless of the University’s Ohio Coal Research Center is
using a $1 million grant from the US Department of Energy to build a
filter that can be attached to the exhaust system of a coal-burning power
station. Before coal smoke gets to the smokestack, it will be bubbled through
water, which will absorb some of the CO2. This hot, carbonated water
will then flow through…
