You're forgetting bootstrapping costs. Sure, an industrial machine may be cheaper in the long term, but he'd have to raise $500k to buy one. In addition, buying an industrial machine lacks the immaterial benefit of bringing manufacturing and engineering jobs and expertise to India. In addition, it's important to note that this is merely a first revision. It's safe to assume, I think, that future revisions would improve upon the design and, due to the agility of manufacturing (how many industrial machines are manufactured per year?), it should be easier to prototype models that improve efficiency, cost and quality. I'd even go as far as to say that if this catches on it will eventually come close to matching the efficiency of an industrial machine for a fraction of the current cost.
