Productive Product: UCLA researchers are able to print batteries on flexible circuits by using nanotube inks, NewScientist reports. There are similar projects, such as at Rensselaer Polytechnic Institute, and it's not immediately clear how the UCLA project differs. However, NewScientist explains, "The researchers also made supercapacitors using the inking technique and plan to combine these with batteries for applications requiring more power. Furthermore, since both printed batteries and supercapacitors can be made entirely at room temperature, it should be possible to mass-produce them using established printing methods" ... and that's worth repeating in our opinion.
