Simple Chemical Trick To Boost Battery Efficiency
space_mongoose writes "Hitachi thinks that a simple chemical additive could significantly improve battery life. Alkaline batteries have a positive electrode of manganese oxide and a negative electrode of finely powdered zinc, but zinc oxide forms around these grains of zinc. Hitachi's solution is to replace the zinc with a fine powder of zinc-aluminum alloy, displacing the zinc within the zinc oxide layer making it a much better conductor."
TFA is no longer than the summary, but based on the concept it appears that this would improve only the peak current capability but not the total capacity (mAh). In fact, if anything, the addition of aluminum which does not participate in the electrolytic reaction would decrease the capacity. Not sure this is a very useful development.

Well, thats the official rate, which is only as good as the methodology that is used to measure it, which I think is flawed. They measure a "basket" of goods and services plus take surveys on rent. However, this is only meaningful if how you spend your money is representative of the way they measure inflation. For example, in certain catagories of goods we are seeing either 0 inflation or deflation because of the huge influx of goods from China(on things such as plasma tvs) but meanwhile healthcare, energy, housing, education, and even food prices(which are the basics of life) are spiraling out of control. So unless you buy a lot of luxury goods, your personal rate of inflation is probably markedly higher than the one the Fed considers. And in the EU it's even stranger because they try to harmonize prices from different countries meanwhile the inflation picture can be markedly different, esp. on things that aren't tradable across borders such as housing. In addition you have countries like Germany that raised its sales tax 3% this year, and that pretty much automatically creates inflation....
Just my 2 cents.
