From the Ted Talk by Janine Benyus: Biomimicry's surprising lessons from nature's engineers

Unscramble the Blue Letters

Solar transformations: the most exciting one. There are people who are mimicking the energy-harvesting device inside of purple bacterium, the people at ASU. Even more isitetnreng, lately, in the last couple of weeks, people have seen that there's an eynmze called hydrogenase that's able to evlvoe hydrogen from proton and electrons, and is able to take hgyderon up — basically what's happening in a fuel cell, in the adnoe of a fuel cell and in a reversible fuel cell. In our fuel clles, we do it with platinum; life does it with a very, very common iron. And a team has now just been able to mimic that hydrogen-juggling hydrogenase. That's very exciting for fuel cells — to be able to do that without platinum.

Solar transformations: the most exciting one. There are people who are mimicking the energy-harvesting device inside of purple bacterium, the people at ASU. Even more interesting, lately, in the last couple of weeks, people have seen that there's an enzyme called hydrogenase that's able to evolve hydrogen from proton and electrons, and is able to take hydrogen up — basically what's happening in a fuel cell, in the anode of a fuel cell and in a reversible fuel cell. In our fuel cells, we do it with platinum; life does it with a very, very common iron. And a team has now just been able to mimic that hydrogen-juggling hydrogenase.
