It may seem a scam at this very moment, but I believe it will get
lined out in the future and become very cost effective, and the
technology grows.
take a look at where the computer has gone from the ABC

I'pods and memory sticks have more capabilities than the top computers

I may be wrong, but I think that the hydro-cell has a place in the
near future.
Anything "new" is cost prohibitive .
