It’s possible to rearrange complex molecules from plants to create fuels for cars and electricity. I work in a laboratory where I mix leaves, corn husks, and other plant materials to make fuel. I’m constantly experimenting with plant materials to find the right combination. The new fuel is suitable only if it can be made inexpensively and creates enough energy to supply our needs. After mixing a solution and testing to see if it works, I estimate the amount of energy the fuel can produce and compare it to the cost of production.
