That's pretty basic stuff ~ just cut, weld, snag, grind, hook in ~ you can cut an adaptive bracket for anything to anything in almost nothing.
Now, as far as major manufacturers doing anything? They'll never get in on it. Due to the Great World Wide Obama Recession labor at custom shops is too cheap, so everything is going to be custom for quite some time.
Then we need to have an electric drivetrain. Fortunately, everything learned from electric cars and hybrid vehicles the last few years will be applicable to the E-cat, so this part should be relatively easy for all the automakers who have hybrid/electric cars on the market. (The ones that don't will get hammered and may be headed for bankruptcy.)
The key is the heat to electric conversion. I think it can be done, but I don't think there is anything off-the-shelf that can be used. I'm not well-informed on that, however.
