Couple of comments:
First the energy is not free no matter how it is collected. The device doing the collecting cost money and incurs maintenance costs.
Second you seem to be switching track here. Now you are talking about something becoming cost effective 'eventually' as the cost of crude climbs. I thought your original focus was on replacing fossil fuels in the short term to reduce CO2 emissions.
So what really are you after?
