I plan to make a fun little kart thing that will power me around. What I need help with is the motor! I know I could pick up an electric scooter motor or wheelchair one but I am looking at industrial motors cause there are more available. Now I weigh 70kg and the unit the motor will drive will say be 10kg so around 80kg all up. what motor will work for me? I look at these motors and read the power and rpm but what is it i need to know? I need torque as i want it to get up and go rapidly but it also doesn't need to go insanely fast!(maximum 20mph or so) Can someone please explain to me what i should look for in a motor before i buy. thanks

You might check Ebay for a 12 or 24 volt 1 Horepower/750 Watt electric motors. Graingers will have them new. You should be able to order them through Tractor Supply if need be. Anything between 1 and 2 HP will get you moving. 1 horse of DC electric translates to roughly 3 horse gas lawnmower engine.
You might find a higher rated voltage permanent magnet type off of an electric treadmill still rated for 1 horsepower. They can be operated at lower voltage potential with increased current draw unless you have the speed controller or hook up a motor speed control circuit to limit current draw to a safer level. Something with a PWM aspect in the power control to control heating and reduce power consumption slightly. You might even get lucky and have the treadmill motor speed control board with MOSFETS that you can modify as well.
If you construct something like what you see on youtube for "bierkeiste" such as http://www.youtube.com/watch?v=5Fqpp-IAXF0 although these are gas powered.
You can increase your road speed by using step pulleys, or better- chain drive. If you remove the coasting clutch from a 10 or 12 speed bike wheel cluster set, you can weld that to the pulley on the front of the treadmill motor. and mount a mate to a hub on your driven axle so the large gear on the motor faces the small gear on the axle (slower startup but higher top speed to a point).
If needed, make a trailer for the batteries and use welding cable for your connections between the driven bierkieste and the trailer with the spare batteries.

What are some everyday steps to reduce fossil fuel consumption?

Answer
1 - drive less (if you can walk, bike or take a bus/public transport there, do it)
2 - Check where your electricity comes from? If the plant that produces it is based off natural gas, burning coal, or anything other than nuclear or hydro-electric power (water running through a dam), then use less electricity by turning off the lights, setting the A/C to a higher temp, etc.
3 - Recycle! A lot of products are produced using fossil fuels (plastics, glass, etc)... Recycle your waste from what you consume!
