Peepee Power

There’s a terrific new article in New Scientist about some of the ways scientists are working on turning pee into energy. There’s a lot of pee in the world all going to waste, often at huge cost to the environment in terms of energy used to collect and purify waste water. Methods that can produce…

My two great thesis project loves are hydrogen and symbiosis, and as such, the recent news of a multicellular organism that lives in a completely oxygen free environment and gets its energy from hydrogenosomes instead of mitochondria is totally fascinating. Hydrogenosomes are organelles that are evolutionarily related to mitochondria. Mitochondria generate energy for the cell…

Agapakis et. al.

My paper, “Insulation of a synthetic hydrogen metabolism circuit in bacteria” just came out in the Journal of Biological Engineering! And it’s open access! We designed a metabolic circuit in bacteria that produces hydrogen (a potentially useful fuel) from natural precursors in the cell. The proteins in our synthetic pathway work to make hydrogen by…

Open Source Hydrogen Cars

Riversimple, a small UK-based company, has designed a tiny, relatively cheap, and remarkably open-source hydrogen fuel cell car. The car will not be available for sale, but people will be able to lease it, with the lease agreement including maintenance, fuel, and the eventual recycling of the car. This unique business model allows for the…
