Interesting Way to Save Oil

I can remember telling my sister once that I remember when regular gasoline was $.89 per gallon.  In retrospect, I see how that could make one think I must be older than I am, but I really just have good long-term memory.  Being as it may, I've often wondered how the price went up so drastically over the past 20 years or so (20 years??? Wow! I AM getting up there!).  The simple solution is supply and demand.  But check out how this Korean company is decreasing the amount of oil usage by consumers. Do you think this would work in the U.S.?
