Well now. Just as the so-called first world is getting ready to phase out incandescent light bulbs, boffins in the US have apparently found a way to make the humble globe more efficient. In short, they simply add a small step to the existing manufacturing process: zapping the filament with a infinitesimally short pulse of extremely high-energy laser light.

The result is an otherwise conventional light bulb that consumes 40% less energy producing the same amount of light. Read the full story on El  Reg here. What isn’t clear is how this process affects the longevity of the common or garden variety light bulb.

Of course, if this does turn out to be the elixir the boffins expect, it will spell the end of Philips’ monopoly on energy-efficient lighting technology. What a shame that would be.
