Biochemist Creates CO2-Eating Light That Runs On Algae
An anonymous reader writes "Biochemist Pierre Calleja has a solution to reducing carbon emissions that doesn't require us to cut back on our use of carbon-producing devices. Calleja has developed a lighting system that requires no electricity for power. Instead it draws CO2 from the atmosphere and uses it to produce light as well as oxygen as a byproduct. The key ingredient to this eco-friendly light? Algae. Certain types of algae can feed off of organic carbon as well as sunlight, and in the process produce carbohydrate energy for themselves as well as oxygen as a waste product. Cajella's lamps consist of algae-filled water along with a light and battery system. During the day the algae produce energy from sunlight that is then stored in the batteries. Then at night the energy is used to power the light. However, as the algae can also produce energy from carbon, sunlight isn't required for the process to work. That means such lights can be placed where there is no natural light and the air will effectively be cleaned on a daily basis."
First they came for the communists,
and I didn't speak out because I wasn't a communist.
Then they came for the trade unionists,
and I didn't speak out because I wasn't a trade unionist.
Then they came for the Jews,
and I didn't speak out because I wasn't a Jew.
Then they came for me
but I had returned to gamemakerdom!
They didn't stand even a single chance!
The number of chances they stood was equal to zero!
RETURN TO GAMEMAKERDOM TODAY
carbon neutral electricity is easy to produce. It's been possible since the '70s, but hasn't been deployed because greenpeace types hate it. Presumably because it makes cheap, carbon-neutral electricity possible, and they want to guilt-trip us into a sustainable, locavore culture of subsistence agriculture.
Check out the liquid fluoride thorium reactor, or (my personal favorite because it's just so damn cool) the traveling wave reactor.
