The Millennium Technology Prize has been awarded to Shui Nakamura.
Professor Nakamura has developed a new, revolutionary source of light – bright-blue, green and white LEDs and a blue laser. The technology is used in several applications which improve the quality of human life. The world’s largest technology prize, now being awarded by Finland’s Millennium Prize Foundation for the second time, has a value of one million euros. …
One of the most significant future applications for Shuji Nakamura’s invention is the sterilisation of drinking water, since the use of ultraviolet LEDs makes the water purification process both cheaper and more efficient. Systems based on this technology are expected to improve the lives and health of tens of millions of people.
This is just the sort of technological advance the world needs.
