It looks as if non-metric measurements will not be banned in Europe until 2010 instead of 2000. The European Union (EU) in 1989 had ruled that the English system of pounds and inches would be forbidden in European commerce after Dec. 31, 1999. Only metric measurements would be allowed in technical manuals, user instructions, product advertising, catalogs, and packaging labels. Dual listings of the two systems would be prohibited. An exception was made allowing England to continue using miles and pints. American manufacturers and exporters, still strongly attached to English measurements, have protested the impending ban. They point out that the U.S. Fair Packaging and Labeling Act requires the listing of dual measurements on products. European exporters to America say the combination of the EU restriction and the U.S. requirement would cause them problems, too. As a result, the European Commission now recommends postponing EU's ban for 10 years.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
