I don't think a "well-to-wheel" analysis is relevant here, for two reasons. First, because it involves electrical energy as an intermediate product, which could be converted to kinetic energy in ways that are orders of magnitude more efficient. Second, because I'm analysing this based on the amount of energy that is initially invested, not the total quantity of energy that exists in nature. EDITED because I said converted to electrical energy when I meant kinetic energy.
