I like the put up or shut up attitude they've taken. But wouldn't more terrestrial testing be better before they go to the expense of launching it in space?
They're sending up a CubeSat which looks to be pretty small, from Googling it looks like the cost to launch could be $40-60k USD.
I'm not familiar with testing things like this, but I could very well see that being cheaper than hiring out a well-qualified lab to test it out.
