I was pondering our reliance on and the limitations of todays electrical batteries. It seems to me (uneducated member of the public) that while technology continues to develop with an impressive momentum our energy storage methods struggle to fuel these ever evolving technologies effectively. What extends the operational time of our phones, laptops or even cars isn't primarily the development of improved batteries; It is mainly the development of more energy-efficient technologies. My question therefore is: Are there any promising projects going on that could provide us with the much necessary high capacity, mobile, energy storage? I did a bit of research and came across http://www.ens-newswire.com/ens/mar2011/2011-03-24-091.html". Sounds very promising although while it will allow me to recharge my phone in seconds it still won't change the fact that my phone will die after several hours of usage.
