Mar 2 2013: Goals are great to create focus, but any goal needs measure to validate its worth. Is eliminating the petroleum in the vehicle creating a more efficient and clean mobility, or is it just moving the inefficiency and pollution to another location? Each time the energy form is converted, there is energy loss. A more meaningful goal may be to start with a known concentrated energy source and finding a more effective method to convert it to kinetic energy. How can we deconstruct the complex molecules to their simplest components while capturing the energy release at a much higher efficiency than burning?
