Fossil fuel has been a major concern in supply and some countries that produce these products use as political and economic weapon against those who they disagree with. With this being so, alternative sources are now developing.

Hydrogen Fuels

Hydrogen is a likely source that has endless possibility. As a new source of fuel, hydrogen fuels have the ability of production from common elements. However, the use of hydrogen has been problematic for safety and containment reasons. Now new development in fuel cells to contain and store hydrogen safely is in experimental stages and in some cases in use.

Free Energy Concepts

The theory of free energy may be workable. Development of magnetic/kinetic motors show signs of functionality. The magnetic flywheel design is in experimental stages but used in congruence with like polarity repel and opposite polarity attracts. This has potentially endless possibilities if development continues.

Body Design

In body design of automobiles metal may be a past material as the development of composite materials. The positive sides of composites are lighter in weight and far more durable properties. As metal is industry standard the car industry has a great deal of change to implement composite usage the expense of becomes a factor. Even so the use of composite materials increases safety, efficiency and durability and could possibly be worth expenditures. 

Conclusion

With the economic troubles and concerns of the auto industry crying out for bailouts. Given these subsidies at tax payer expense, funds given should be used wisely to develop alternative products that are safe, likable, durable and energy efficient, thus a new way of looking at viable changes has to be made.
