A Spinach-Powered Laptop?

from the i-yam-what-i-yam dept

Roland Piquepaille writes "In "Could laptops run on spinach?," Nature reports that researchers from the MIT have made solar cells powered by spinach proteins. These prototype solar cells which transform light into 'green' energy could be used one day to coat and power your laptop. There is still work to be done before becoming a commercial product. Right now, the prototype delivers current for only three weeks. And they are not very efficient, converting only 12% of the light they absorb into electricity. However, these spinach-powered solar cells are better for our environment than silicon solar cells. And according to Science News Online, in "Protein Power: Solar cell produces electricity from spinach and bacterial proteins," they also have the potential to be self-repairing. You'll find more excerpts on my blog." Anyone else think this sounds ridiculously over-simplified? Thinking about how much energy would be needed to run a laptop would suggest that spinach farming would have to become mighty popular, and you may need to coat your house in spinach if you wanted to actually use it to power a computer.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

    What about blight?

    Bacterial chlorophyll, made by cyanobacteria, and plant chlorophyll are different chemicals. What if bacteria or viruses get into the solar cell, so the house of spinach turns into a house of brown ooze?

    Speaking of the latter, our excrement is 50-90% pure bacteria, and doesn't need sunlight. Couldn't a big piece of shit light a bulb or two?
    Since the sun doesn't shine inside a laptop, wouldn't it make sense to have a USB port on a colostomy bag? Or maybe firewire if you ate Mexican food.
