We all want the technology to advance significantly in the battery ... but ... Are we ready to spray batteries?
Researchers at the University of Rice University in Houston (Texas) developed a battery that can be "painted" on any surface, and thus evade traditional settings that associate with the batteries (rectangular, cylindrical, etc.).
While there are still obstacles to be resolved ... that will be here for a few years all surfaces, including walls of our homes may be batteries? (It was the way that simplifies the use of UPS ... enough to load the "ink" in each division to serve as a backup in case of lack of energy;)
