Urine Powered Battery Developed

Posted by ScuttleMonkey (36% noise) View
Saeed al-Sahaf writes “Research investment into developing smaller and cheaper chips to process information in disposable health tests has been significant, but they were still reliant on an external power source. The researchers at Singapore’s Institute of Bioengineering and Nanotechnology think they have overcome this problem with their latest urine powered battery. From the article “The battery is composed of paper, soaked in copper chloride, sandwiched between layers of magnesium and copper. The whole thing, once laminated in plastic, is just a millimeter thick, and 6cm by 3cm in size.” The breakthrough promises a cheap and disposable power source for home health tests.”

Great! Now I don’t even have to get off the couch to change the batteries in my remote anymore. And as a side benefit, I don’t have to *share* the remote anymore.

Are they sure that it’s urine powered? - by ChiralSoftware (Score: 5, Informative) Thread
It sounds like it’s using urine as an electrolyte. That’s like a “potato battery”, which again is just using the potato as an electrolyte, and is not getting any power from it.

1 battery outputs 1.5 mW / 1.5V = 1mA 
theoretically you could get 1A at 1.5V by wiring them in parallel, OR 1mA at 1500V by wiring them serial, both outputting 1.5W of power.

Ok, so the first two beers are warm. I could live with it.

I am a social Entrepreneur a social-Preneur. I am a thalidomider and a wheelchair user. I am a biochemist and a bioethicist. I am a scientist and an activist. I work on issues related to bioethics, health research, disabled and other marginalized people's and human rights, governance of science and technology and evaluation of new and emerging technologies. I am the founder of the International Centre for Bioethics, Culture and Disability and of the International Network on Bioethics and Disability. I believe that a wide open public debate on how the above issues affect society and marginalized groups is the only way to develop safeguards against abuse. I believe that so far marginalized groups are rarely heard in this debate. Therefore I try to increase the visibility of marginalized groups on governmental, academic, civil society, national and international level. I hope that the tools I offer (webpage, listserves, briefing papers, workshops, lectures and online courses) help people from marginalized groups to increase their knowledge and I hope my tools help others to obtain a more differentiated picture of people from marginalized groups and how the issues affect them.
