Seems to good to be true. Can this secret have eluded GE, Phillips, Sylvania, etc for the last 50 years?
It may well be too good to be true - I'm not evaluating it as I'm not a physicist - I just thought it worth sharing since it was published in a reputable news outlet by a reporter who has a good record.
However, there was no incentive for GE, Philips, Sylvania, et al to investigate any improvement to incandescents until they were outlawed rather recently (largely due to lobbying by Philips and others). And, then, it was easier to make high profits on CFLs than it was to investigate improvements to a 25 cent commodity.
And, that may be a problem even if this guy knows what he's doing. Will people be willing to pay enough more for an incandescent to justify GE, et al to restart their production lines or possibly invest in new processes? The inventor seems to think they'll be cheap and that electric utilities might want to supply them
free in lieu of building new generating plants.
