Super cool. Chemical fuels (hydrocarbons or even plant oils) have ridiculous energy density, which is nice for e.g. cars but absolutely crucial for fast, long-range air travel. I don't think we'll be saying goodbye to jet engines for a long time, and it's awesome that we have ways of making fuel in a somewhat sustainable fashion.

The US Navy has experimented with this, but I think the idea is to use nuclear power instead of solar energy. Makes sense for an aircraft carrier with a big reactor and thirsty jets.
