Other technologies that use aqueous electrolytes and have the potential to be useful in future large-scale applications are briefly introduced.
In past years the F.C.C. has taken steps to promote new wireless technologies that use unlicensed spectrum.
Second, existing technologies that use coal more efficiently can be deployed, particularly in the power sector, which accounts for two-thirds of global coal use.
With varying degrees of support from Nintendo, four electronics companies have developed technologies that use the Game Boy Advance SP's 2.4-by-1.6-inch 2.4-by-1.6-inch 2.4-by-1.6-inch 2.4-by-1.6-inchfull-length moviescreenull-motoon video.
Researchers around the world are fine-tuning technologies that use standard lighting equipment to cheaply transmit high-speed data streams wirelessly, even while the equipment appears to be producing nothing more than normal illumination.
The company, which says it has more than two million customers and 700,000 e-mail subscribers, is embracing technologies that use cellphones and remote controls to enable purchases directly from a television set.
Digital mammography, which costs Medicare much more than older technologies that use X-ray film, is widely approved for women who have already had suspicious breast tumors detected, but experts say there is no evidence to justify the extra expenses of digital for routine screening.
Here's what we can do — now: we can make an immediate and large strategic investment to put people to work replacing 19th-century energy technologies that depend on dangerous and expensive carbon-based fuels with 21st-century technologies that use fuel that is free forever: the sun, the wind and the natural heat of the earth.
Rather than joining another big media company, Mr. Chernin is in the early stages of assembling his own enterprise, a company of considerable ambition that will meld original content, like feature films and television series, with cutting-edge technologies that use the Web and other digital ways of delivering entertainment.
It would have been much better, he argues, to invest in proven technologies such as electrical interconnectors (linking Britain and Norway, for example) and support research into new kinds of solar power, such as films that can be applied to any outside surface and technologies that use a wider chunk of the spectrum.Bits of the green-energy world are wilting under the impact of low oil prices.
Tissue engineering technologies that use amniotic fluid cells are being explored.
