Light without electricity? Glowing algae could make it possible (opens in new tab)

> Because these algae are photosynthetic ... "We’re storing carbon while we’re producing light"

The circle of light! Perpetual illumination! Let the algae do photosynthesis using their own light output as energy!

What's happening, chemically? Let's see ... it's luciferin. https://en.wikipedia.org/wiki/File:Luciferin_Light_Emission_... Isn't that CO2 being emitted on the right, there?

I hope this works. A decade ago I submitted glowing microbes to the epa but they blocked it. My read from going through that was that it was politically impossible. Hopefully times have changed.

Edit: my microbes were gmo, these are not, so no epa rules. Good luck to them!

I remember old watches that used to have some phosphors dots on the 4 main quarters in a hand watch to see time in the dark, while as kids we would take a to bed a rosary with glow-in-the-dark marbles to emit light from the phosphors inside.That would last for 30 minutes or more.

Modern LED lights really draw no power at all in the grand scheme of things

This feels like weird framing. They still need energy to produce it.

I have a genetically engineered luminescent petunia plant. It’s neat, but a ways off from being useful for anything.

So can torches and candles.

It rather resembles the CGI protomolecule from 'The Expanse'.

Why all the bother with 3d-printed gel shapes? Why not just use a mat of these things, all glowing, and then put it behind an LCD panel. Then you can have moving pictures without all the bother of 3d printing.

Then you can take the next step and both their apparent output further by replacing the algae with tiny blue LED modules.

good for car dashboards, maybe for not vital areas

Technically [nerd emoji] nothing is possible without electricity

(No I don’t go to any parties)
