We had an inventor here in KC in the late 70's who had several Hydrogen cars sunning back then. He would even drink the water that came out of the exhaust!! Nothing new here, it is simply the need for infra-structure that keeps this from happening.
""We have produced all the hydrogen we need for the coast-to-coast trip using power from the grid, but because they pay us more to put power on the grid from our solar cells than they charge us when we use grid power for electrolysis, we actually have a surplus in our account," - interesting business idea! Let's all of us do that and make more money ;-)...So what happens when government stops subsidizing solar power? Kris
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
