I also think these solar-hydrogen systems will benefit from scale as the marginal cost of production drops. Examples like the cost of producing microwave ovens, for example, have dropped from thousands to less than one hundred dollars with economies of scale. As a manufacturing sector of competing parts suppliers emerges, we will see price come down to benefit home owners.
