As a business speaker, I am always looking for great businesses to speak about. I saw a great program on Modern Marvels about cars that are powered by compressed air. Rather than using the internal combustion to move the pistons in the engine, a blast of compressed air does the job. It is incredible.
MDI is the name of the company and they have cars on the road now and available. Their business model includes building boutique factories close to the markets they plan to sell in to keep costs down and keep community involvement high. Great concepts.
