Edit (July 22, 2013): A reader notes that 100% electric and plug-in hybrid electric vehicles should also be included here as revolutionary technologies. I fully agree.
Awhile back, on sister site Red, Green, and Blue, an article by David Brin was published with the title “Technologies that could change everything.” At first, I was afraid it was going to be about technologies far on the horizon that could change everything if they ever came about as market competitive, but which would probably never hit the market.
I was happily surprised. The first technology mentioned was LEDs. “Take this year’s arrival of reasonably priced and stunningly efficient LED light bulbs, for example. Businesses are already doing whole-building replacements and you should start now in your heavily-lit areas. They pay for themselves so quickly that fluorescents are hogs, by comparison. Within two years, incandescents and pigtails will be considered bizarre or quaint. That’s one game-changer.” Excellent.
The second was solar PV. Just following, “That’s one game-changer,” Brin writes, “Another is the rapid fall in prices for solar energy. Photovoltaics can’t yet compete with the plummeting (in the US) price of natural gas, but their economics are surprising cynics and could accelerate soon.” (Link added.)
