Just as we're phasing out incandescent light bulbs for energy-efficiency, someone invents a cheap way to boost incandescent efficiency by more than 65%:
The process could make a light as bright as a 100-watt bulb consume less electricity than a 60-watt bulb while remaining far cheaper and radiating a more pleasant light than a fluorescent bulb. Despite the incredible intensity involved, the femtosecond laser can be powered by a simple wall outlet, meaning that when the process is refined, implementing it to augment regular light bulbs should be relatively simple...
It seems that Professor Chunlei Guo of Rochester hit upon the idea of brightening-up lightbulb filaments following earlier experiments in which he and his team used laser zapping to turn metals completely black. This worked so well that Guo and his cohorts wondered if they could reverse the process.
"We fired the laser beam right through the glass of the bulb and altered a small area on the filament," says the prof. "When we lit the bulb, we could actually see this one patch was clearly brighter than the rest of the filament, but there was no change in the bulb's energy usage."
It seems that Guo and his team of lightbulb-blasting boffins can also produce other strange effects, getting incandescent bulbs to emit partially polarised or differently-coloured light - without the energy-wasting filters that would normally be necessary.

"The presentation or 'gift' of the Holy Ghost simply confers upon a man the right to receive at any time, when he is worthy of it and desires it, the power and light of truth of the Holy Ghost, although he may often be left to his own spirit and judgment." --Joseph F. Smith (manual, p. 69)
