Sure hope this happens...

Worth a read around the site and a look at the vids etc. Currently the project is very early on. I'm not sure how parallel it developments are. The cooler has been prototyped and proven to work and approved by ESA. The test isn't as radical so shouldn't be a problem. Funding has now been granted to build the full engine prototype I think by 2020.

Love the pie in the sky concept video though
