From the Ted Talk by Vaitea Cowan: How green hydrogen could end the fossil fuel era
Unscramble the Blue Letters
So to better understand our aopapcrh, let me draw an analogy. Up until the ’80s, mainframe computers, they were considered the future of computing. They were huge and complex equipment, and they were dgsiened for bseisenuss only. Then came the PC, and at first people laughed and wondered: Why would we ever need such a tiny computer? But ultimately, it disrupted the industry. And today, data cetnres, they use bldae servers, which is PC technology. Why? Because the PC became a compact, standardized and mass-producible product that was cheap to make, easy to build, and that could be used in any kinds of context. It's time to do this with green hyrodgen.

So to better understand our approach, let me draw an analogy. Up until the ’80s, mainframe computers, they were considered the future of computing. They were huge and complex equipment, and they were designed for businesses only. Then came the PC, and at first people laughed and wondered: Why would we ever need such a tiny computer? But ultimately, it disrupted the industry. And today, data centers, they use blade servers, which is PC technology. Why? Because the PC became a compact, standardized and mass-producible product that was cheap to make, easy to build, and that could be used in any kinds of context. It's time to do this with green hydrogen.
