Every child should at some point construct a lemon battery. It was a fabulous learning experience for my kids, and a fun way for me to help them learn a little bit of basic circuit theory and electrochemistry.
I was looking for a catch in this technology as this might be it: production scalability and market feasibility. Ofcourse i donot want to carry a chemical bomb in my pocket nor do i want to carry an extra bag just to carry my battery.
When I hear cheap organic battery I think Lemon battery. Lemon trees grow OK in the silicon valley (Not as well as 400 miles further south.) So there should be a good source of lemons.
The problem with batteries and fuel cells is not the active chemicals, it is the case and insulators. Researcher need to find a good insulator which can pass electrons without catastrophic failure due to the reactions breaking the system down.
Designing a good battery that does not leak, would be an advantage too.
Misleading headline. Scientists have not really announced a battery. They just described a chemical process with some potential for a cheap organic battery if some hurdles can be overcome in some distant or unknown future.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
