That’s right, the 1968 launch of Apollo 8 was powered by hydrogen fuel cells, a technology that Francis Bacon adapted for NASA’s use. This efficient and “carbon neutral” power source has been continually used by the space industry ever since. The more impressive thing is that the by product of fuel cells is water, and NASA is able to capture it for the astronauts to drink. Now, that sounds like Waste = Food/Cradle to Cradle to me!

So, why aren’t fuel cells a regular source of energy?  Why can’t I fill up with hydrogen?  Well, the sourcing of hydrogen and the process of converting it into energy are not yet sustainable and are more costly than gas.  However, many companies around the globe are working on creating renewable hydrogen, therefore lowering costs.  This is definitely a technology with a huge Green potential.
