Good info. I'd agree that several solar masses of energy could be put to better use. But we've gotta start somewhere, and this seems like an advance from stuf

Good info. I'd agree that several solar masses of energy could be put to better use. But we've gotta start somewhere, and this seems like an advance from stuff that does not exist (as far as we know) to 'just' large quantities of stuff that does exist. No harm in continuing to work on it?
