An alternative to gasoline as fuel is needed badly. Many technologies exist, but most development has begun so recently, that much more time and money is needed to replace gas. In prior gas shortages people have used one technology not often talked about, called woodgas. Woodgas is a gas that is made by heating wood until it chemically changes into a clean burnable gas and a solid coal. Vehicles can be run off of woodgas as well as very clean burning heaters with no smoke. One downfall with the setup is the need for a “furnace” to “cook” the vapor out of the wood. Placement of the wood inside the furnace is very critical as is the way the air enters and exits the device. The airflow is usually throttled to control the rate of conversion into the gas. Many people used trucks or small trailers for the room to process the wood. Due to the efficient gas, a piece of wood can last for quite awhile longer than a burning piece of wood.
Wood contributes no more carbon dioxide into the atmosphere than was first put into it making it environmentally friendly. Many third world countries use this process for community stoves or to power equipment. This is at least an alternative to being stuck with only one form of fuel to run a country off of. The price of wood is reasonable you would only have to make room for it. Woodgas will not adversely affect your engine and will run similar to running propane through your engine. The longevity of your engine should be similar if not better due to less carbon deposits. This is a fuel alternative that is readily available and has been successfully used in the past, and is worth looking at.
