Underwater Chemical Garden Powers a Light Bulb

Posted by Soulskill on from the two-green-thumbs-up dept.

Zothecula writes: Researchers at NASA's Jet Propulsion Laboratory have grown underwater chimney-like structures capable of generating enough electricity to power a light bulb. The team linked several of these chimneys to get the required electricity. Their findings indicate that the seafloor equivalents of these chemical gardens might just have contributed the electricity needed for the Earth's first organisms to develop.

    Can we please replace ubiquitous terms like "can power a light bulb" with the precise voltage + wattage or amperage that they were able to obtain from their energy source, in addition to the time it was able to sustain this energy output? Maybe also mention the mass and density of the substance providing the energy? If we could get this going in the description/abstract, that would be really great.
