In the bionic leaf, the hydrogen gas is fed to a metabolically engineered version of a bacterium called Ralstonia eutropha. The bacteria combine the hydrogen with carbon dioxide as they divide to make more cells, and then—through a trick of bioengineering pioneered by Anthony Sinskey, professor of microbiology and of health sciences and technology at MIT—produce isopropanol (rubbing alcohol), which can be burned in an engine much like the gasoline additive ethanol.

Ultimately, though, Silver’s goal is not to create fuels from this work, but “high-value commodities” in remote places. ...
Drugs, on the other hand, are high-value commodities, so engineering a bacterium to produce ... a vitamin or a drug may be her next goal for this system.
