The thing about groundbreaking efforts into doing a think like this is that you can't judge its merits simply on the first initial efforts. They've managed to do a cool thing through hard work and cool science to produce something new in the world, however inefficiently it may be. Now that it's fact, not theory, they can go back and refine it. The various events in life that led up to all the great technological breakthroughs would have them as incredible and useful, but unrefined ideas. And then, over time, they are improved. The internal combustion engine is one such device in history that follows through this. Back then, they were noisy, clunky, inefficient, smelly, and definitely bad for your health. Now, the Stig moves around at 100 MPH easy, in comfort and safety, for our benefit. This technology will improve and be embraced.
