if you picked up a hot poker left in a fire? - CORRECT ANSWER - conductive
There are a couple of "new" coal-fired electricity electricity generation technologies that are
much cleaner and more CO2 sequestration ready than current plants. One is oxy-fuel
combustion, the other is [answer]. - CORRECT ANSWER - gasification
Why did we use large amounts of fossil fuel and nuclear derived electricity when renewable
energy was available? - CORRECT ANSWER - it was much cheaper
