I've been thinking, which, for me is strange.
What's stranger, i've been thinking about saving the planet.
I don't believe that global warming is solely the fault of man and his machines, nor do i believe that we're all going to fry in a ten-thousand year summer, but that's not the point of this forum, and i'd appreciate no comments labelling me as a communist, or a planet-hater.
What i had in mind is a new system of lighting. Say i took some LEDs (lets say 16) and connected them in paralell, and attatched them to the appropriate power source, would they be more or less efficient than a tungsten filament lamp?
As for aesthetic considerations, to simulate natural sunlight during winter months, one could add blue or yellow LEDs to tune the shade of the light.
Would this idea be more efficient than the lights we have? (i avoided mentioning those energy-efficient lights because they're not really that efficient, and give crap light.)
