Hey Josiah,
Thanks for asking, there have been a lot of questions around Adam's algae battery and he's asked me to help with responding briefly to the questions. He's going to be pulling together a FAQ for a lot of the questions that he and I were asked (we were pretty much flooded with emails and calls the last couple of days). In a nutshell, this is very early tech, so it's most definitely a work in progress and as with much early stage science, there's no guarantee it will definitely work but Adam's working hard to finish off the prototype.
I'll be sharing the FAQ in a few weeks and we're looking forward to having a prototype to show in about 2ish months. Bear with us as the article came out a lot faster than we expected it would.
