A Fair Warning:
Signal Lock is an LED warning light thats fit within the frame of a bicycle and comes in real handy when you are stuck in the middle of nowhere. sure we can move the bike on the road, but this is better safe than sorry. It would be hip to repair your cycle with a LED warning light beaming your presence and distrees from 100 meters away anyways.
Citizen's Memory LCD:
Citizen has developed something it's calling the "memory liquid crystal," a new passive matrix LCD that can retain an image even when powered off. According to Citizen, the display's inorganic membrane, combined with an angled orientation, keeps the crystals frozen in position without power having to be maintained. The five-volt, non-backlit display isn't going to take the place of your LCD TV anytime soon, but is planned for use in point-of-sale applications, watches and cellphone auxiliary displays.
Can the World Be Powered Mainly by Solar and Wind Energy?
Continuous research and development of alternative energy could soon lead to a new era in human history in which two renewable sources -- solar and wind -- will become Earth's dominant contributor of energy, a Nobel laureate said in Boston at a special symposium at the American Chemical Society's 240th National Meeting on August 24.
Walter Kohn, Ph.D., who shared the 1998 Nobel Prize in Chemistry, noted that total oil and natural gas production, which today provides about 60 percent of global energy consumption, is expected to peak about 10 to 30 years from now, followed by a rapid decline. He is with the University of California, Santa Barbara.
"These trends have created two unprecedented global challenges," Kohn said. "One is the threatened global shortage of acceptable energy. The other is the unacceptable, imminent danger of global warming and its consequences."
Kohn noted that these challenges require a variety of responses. "The most obvious is continuing scientific and technical progress providing abundant and affordable alternative energies, safe, clean and carbon-free," he said.
Because the challenges are global in nature, the scientific and technical work should enjoy a maximum of international cooperation, which fortunately is beginning to evolve, he said the global photovoltaic energy production increased by a factor of about 90 and wind energy by a factor of about 10 over the last decade. He expects vigorous growth of these two effectively inexhaustible energies to continue during the next decade and beyond, thereby leading to a new era, the SOL/WIND era, in human history, in which solar and wind energy have become the earth's dominant energy sources.
Another important issue, incumbent primarily on developed countries, whose population has pretty much leveled off, is reduction in per capita energy consumption, Kohn said "A striking example is the U.S. per capita consumption of gasoline, approximately 5 times higher than the global average," he said. "The less developed world, understandably, aims to bring their standard of living to a level similar to that of the highly developed countries; in return they should stabilize their growing populations."
Kohn noted that he is impressed by students on his campus who spent their own collective funds to fully solarize an athletic building. "When it comes to providing leadership by young people in the area of energy conservation and energy efficiency and global warming -- they are fantastic," he said. "It is a major social commitment for our times."
