It took about a century to get decent electric cars so I stand by my statement. It may no longer be true in the 22nd century, but there are fundamental issues with this technology that have not been addressed. I can't imagine where likely to see solutions anytime soon, mostly because I don't think there are solutions, I just don't think the technology works.

Pressure change refrigeration is just so much more efficient. The light on your refrigerator consumes more energy than the refrigeration process, so it's not like there's even a massive impetus to make the system even more efficient because it barely uses energy as it is.

Where this technology might come in handy is where size is a severely limiting factor. Such as on satellites or small drones.
