Hi Paul, I have been away and am catching up on my reading. It has been a while since my computations you refer to, but I question the 10 million units per year market limitation. About two months ago I was told that a LITH market study had concluded that the portable models of just one major computer manufacturer would require all the capabilities of VLNC, LITH and ULBI combined. The numbers may have since changed, but I would be interested to know the source of the 10 million unit market size - I suspect it is much higher. On another note, I estimate the energy storage capabilities of Valence's new version to be at least 33% higher than the ones already tested by and met or exceeded the requirements the two major OEM's. The improvements should make the new version clearly superior to anything else available and should therefore warrant premium pricing. For some more numbers to work with, add 33% to my example of three 4x4"x 6mm cells/battery for 52.5 watt/hr per battery x 1.33 = 70 watt hours/ battery for the new version. Multiply this times about $1.60 per watt hour and you have a sales price of $112 each (almost 3 times the $40 price in the previous example.) The negotiated price for large volumes may differ, but I remember Cal Reed's yardstick was $2 per watt hour a little over a year ago. I remember a projection to about $1.50 by the year 2000. I would welcome more analyst estimates for the portable computer market. As you mentioned, the replacement market for Li-Ion, liquid electrolyte battery packs should also be considerable. A 4"x4" Valence battery pack might have 1.23(Compaq number for solid vs liquid) x 1.33 (Valence new technology) or about 1.6 times the storage capacity by volume. At about 60% of the weight, it translates to about 2 1/2 times the energy stored by weight when compared with todays liquid-cell canister type battery packs. Does $100 per laptop battery make the numbers come out a little better? Best Regards, FMK
