Light Up Latro Algae Pet Looks Like Beaker Of Green Goo

We all remember from high school biology that plants use sunshine and CO2 to generate energy through photosynthesis, right? An outrageous new prototype lamp from designer Mike Thompson actually generates electricity from algae the same way, in the form of lighting that requires a bit of daily maintenance, not unlike a bonsai plant or a pet.

The Latro (which comes to us by way of Treehugger) requires sun, which can be provided by leaving the device (which really looks more like a huge beaker full of green goo than an actual lamp) outside during the day–or presumably, in a sunny window. While the algae is photosynthesizing away, it will also be charging up a battery, which then releases light, according to the designer “within the hours of darkness” (we assume automatically).

You won’t have to worry about your light-up algae “pet” getting malnourished, as a light sensor monitors light intensity, only permitting the leeching of electrons when the lux level passes the threshold–but you will have to remember to breathe…into the handle, that is, providing your little green friend with CO2 (the side spout allows for the addition of water when it dries out and release of oxygen as the algae respires). Considering how dependent we humans have become on electricity, and how much C02 we produce, one can only regard this as a symbiotic relationship.

    Use me as your guinea pig, i’ll put one in my house and even log my daily observations like a scientist.

    I second that. I actually am a scientist, and I would love to have a few of these in my place to monitor. I have a big south facing bay window, two floors above ground level, which gets more than enough light. I grow tomatoes and herb plants inside, which works very well as the window is like a greenhouse, only double-glazed.
    I would definitely record daily statistics, such as how much water it consumed, how many times per day I breathed into it, when the light switched on (and off) and hence how long it lasted, even what voltage the battery had been charged up to at the end of each day.

    WoW…. how can i get one……. ;-))

    I would think if you put in an airreator like in a fish tank. It would pull out CO2 form your home and add back the oxygen to the indoor air. If you put in a float and hooked up to a water scoure. This would keep the water at same level. It would also seem that size and shape could be made for any sunny area in the home. Just a thought.

    Is this device producing energy in form of heat?
    If so, one could increase its effeciency by applying a sterling engine which serves the purpose of a pump to supply the algea with CO2

    I like this lamp its quite lovely why do they never say how much and where, well it would be an inbuilt market survey…love those helps with bank loans and all the paper work.
