""Zinc-air technology moves toward commercialization
Zinc-air fuel-cell technology, long a promising source of clean energy and stored-energy recovery, begins a move toward commercialization with the recent signing of a Memorandum of Agreement between Lawrence Livermore and Power Air Tech, USA, a consortium of Australian companies. Discussions are under way to bring other U.S. companies into the consortium.
The next step is a Cooperative Research and Development Agreement between the Laboratory and private industry, which could mean about $100 million of industry funding-$30 million for further research and development on a zinc-air fuel cell and its zinc recovery unit at Lawrence Livermore over the next four to five years and an estimated $70 million for commercialization and manufacturing applications of the refuelable zinc-air technology and recovery unit.
Zinc-air fuel cells mix zinc pellets and electrolyte with air to create electricity. They create five times as much power as lead-acid batteries of the same weight. The Livermore design is unique because it is refuelable, and the spent zinc can be recycled into zinc pellets.
The agreement initially is intended to commercialize several kinds of units: large units for utilities to meet peak power demand, small units as an alternative to gasoline and diesel generators for uninterruptable power supplies, units for heavy and lightweight vehicles, and large uninterrupted power supplies for hospitals and airline reservation systems.
John Landerer, on behalf of Power Air Tech, USA, noted, "We will make every effort to have this technology on display in Sydney by the time of the 2000 Olympic Games."

Take note in the Powerzinc.com website that the Chinese will have ZAFCs running buses etc. Let's hope the media takes note of this; I just want jobs created in the US this time around, that's all ! Btw, the zinc oxide pellets use a postassium hydroxide catalyst. Very elementary set-up when you think about it.
