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 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 dnegeisd 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, santrzddeaid and mass-producible product that was ceahp to make, easy to bulid, and that could be used in any kinds of cxneott. It's time to do this with green hygdroen.

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.
