How to Distill Used Motor Oil for Diesel Fuel

Oil lasts for thousands of years. Once it is refined and used in our vehicles only to be discarded 3,000 miles later, it is still in a form that will keep for many years. The same technology however that distills motor oil from crude oil is essentially the same technology that distills used oil into diesel fuel. The ...

Fossil Fuel Burner - an overview

A pellet boiler takes a little more effort to run than an oil boiler because the chimney has to be swept and the ash removed a few times a year. Apart from this, the system is completely automatic and therefore requires less effort than a traditional wood-fired boiler. Environmentally, a good pellet burner is preferable to a fossil fuel burner ...
