Bio-Fuels.
With the ever increasing tension's across the globe and the uncertainty to the constant flow of cheap energy, will this effect the use of machines?
There does need to be a call for more investment into the development of bio-fuels and the use of other forms of energy such as hydrogen cell technology to drive aircraft, trains, and all other vehicles.
The question is will it happen globally or will it be limited, because of the final call by the energy producing giants and the costs or profits for them?
