Geothermal energy in the u.s.
Geothermal energy currently provides more than 2,700 megawatts of electricity nationwide - the equivalent of three nuclear power plants, or enough to power more than 3.5 million homes. A geothermal power plant emits no nitrogen oxides, very few sulfur dioxides and 1,000 to 2,000 times less carbon dioxide than a fossil fuel plant. Reference: http://www.powerhousetv.com/

Why laughing gas isn't funny any more
It is used in surgery and dentistry for its anaesthetic and analgesic effects, where it is commonly known as laughing gas due to the euphoric effects of inhaling it. It is also used as a means to enable short periods of extreme high performance in automobile internal combustion engines by introducing extra oxygen into the intake charge which in turn allows a greater amount of fuel to be added and converted into energy and thereby greatly increasing the power produced by the engine. Nitrous oxide is present in the atmosphere where it acts as a powerful greenhouse gas. Reference:

How Does Lemon Juice Conduct Electricity
Lemon juice conducts electricity because lemon juice is acidic, and because acids break apart into positive and negatively charged ions when mixed with distilled water.The charge is very small, and not enough to power a flashlight, but these particles do conduct a small amount of electricity through the liquid.
