We've seen the video. It makes a lot of steam and noise - that has to be a useful invention to many people. Also I think it makes those around it pose thoughtfully as Alex Walsh is doing in the hard hat hard at work in the video that used to be on the website. We also have been shown graphs on their website that shows it can also heat water to at least 100 degrees cheaper than some other method (which they even admit is using "an old fire tube" that has lost efficiency) so it might be able to used in lukewarm jacuzzis. The press release has 160 degrees but for some reason they didn't put that on the presentation. Another 52 degrees and it can make tea.
