The technology is already here. All we need is new legislation to "outlaw" the old technology, and end it's production. Much like the leaded gasoline was outlawed in favor of No-lead gasoline, and catalytic converters, etc. were all legislated into production nation wide, we need similar laws to get rid of the old, inefficient technology and bring the new stuff into the mainstream. Where do we get those laws? Be careful who you vote for.
