BioLite CampStove – Charge your gadgets in fire - [Link]
Scientists at the University of Washington (USA) have developed a new type of transistor that uses protons instead of electrons for charge transport. It is intended to simplify the interfacing of electronic circuitry to the brains of living organisms, since protons (positively charged hydrogen atoms) and ions are responsible for signal transport between nerve cells. Proton-based transistors are therefore better suited to controlling and monitoring processes in the brain.
The researches discovered that the natural biomaterial chitosan, obtained from squid pens and crab shells, is a good proton conductor. They then used it to fabricate a transistor that can generate proton pulses. The prototype device is a field-effect transistor with a source, gate and drain, but it operates with protons. [via]

Photovoltaic polarizers enable devices to be powered by sunlight
New technology developed by researchers at the UCLA Henry Samueli School of Engineering and Applied Science could finally help solve the problem of smartphones or laptops running down when there is no access to an electrical outlet.
UCLA engineers have created a novel concept for harvesting and recycling energy for electronic devices — one that involves equipping these devices’ LCD screens with built-in photovoltaic polarizers, allowing them to convert ambient light, sunlight and their own backlight into electricity. [via]
