New type of lead acid battery: with silicone wafers

Generally "Scalable" means up but can also mean down.

If this works and is not a whole lot more expensive it may put traditional lead acid out to pasture (It won't put the companies out of business because I suspect it can be made on the same machines) If you can pack say 85 AH into say half the weight I might pick up a few feet per gallon on the old MPG chart.
