Question

Energy Budget for a Rocket in Free Space: Recall the analysis of the rocket engine in Project I, Flight of the Rocket. Although the momentum of the rocket and its exhaust is conserved (constant), their energy is not; energy must be supplied by the combustion of fuel. WARNING: This is not the same as the energy requirement of the jet airplane in Project II, Nonstop Service to Anywhere. Using the same approach we used to derive the First and Second Rocket Equation ---- sequential

In an increasingly complex and interdependent world, it is likely that the future of energy generation will be shaped not by the emergence of any one new technology, nor by the fall of existing industries, but by the measure of our success in co-ordination between existing solutions and innovation. For producers of energy, this means repurposing technology, such as the use of seabed gas extraction equipment to exploit hydrothermal energy; for consumers, themselves small scale producers of renewables, the emergence of a competitive energy brokerage system will have the greater impact.
