Every now and again, a rumor crops up that someone has invented a motor car that runs on water. Sadly, that still remains a rumor, but Green House Co Ltd of Japan will soon be marketing an LED lantern that runs on saltwater. Read More
As development of micro- and nano-scale devices continues to advance, so does the need for an equally-tiny method of powering them. There’s not much point in developing a surveillance micro air vehicle the size of a housefly, for instance, if it requires a watch battery in order to fly. That’s why DARPA is funding a project to create really tiny batteries. Just how tiny are we talking, here? Well, they’re aiming for something smaller than a grain of salt. Read More
To make sunlight practical as a dominant source of energy a viable storage technology needs to be developed. One promising area of research is imitating the process of photosynthesis to separate the hydrogen and oxygen atoms in water to create hydrogen fuel. An MIT team led by Daniel Nocera is now reporting that nickel borate can efficiently and sustainably function as the oxygen-producing electrode in such a process bringing the dream of energy storage systems that would allow buildings to be completely independent and self-sustaining in terms of energy.

German researchers say a new type of electric vehicle battery that runs on electrolyte fluid can be recharged as easily as refilling a petrol tank. When the redox flow rechargeable batteries are low, the discharged electrolyte fluid can simply be exchanged at the gas station for recharged fluid. Read More
