To be fair, I was unable to find the original document, so we don't actually know how many watts the algae generator can provide, we only know how much the computer that they used consumed, also they did note that after 6 months the algae was dead.

That being said, I'm sceptical about the scalability of the algae generator because it's efficiency would have to increase by about 1000x (if we assume that right now it can generate what the computer used while calculating).

Today an average AA battery has t the capacity of 3Wh some even 4Wh. And at 3Wh you could, theoretically, charge your phone at 5V 1A for like half an hour or there about.

Our in other words, what I'm talking about when I question the scalability is energy density. That's the reason why you can do more then 700km with a car that runs on fossil fuels and maybe 350km if it's not too hot and not to cool with an electric car.

Could we engineer there algae to be 1000x times more efficient or even just 500x more efficient, since as long as the algae is alive you don't really need to charge anything. You do need the sun though, these are, from what I understand photosynthetic algae.
