I have long believed that the next great emerging technology would be in the field of capacitors or batteries. We rely so much on laptop computers and smart mobile phones now, and yet many of them seem to require constant charging.
What we need, in the first place, is a battery which will power a laptop for a complete day on a single charge. Only then will laptops be truly mobile devices. At present, whenever my laptop is completely un-plugged and wireless, I feel like the guillotine is about to fall. I hurry through what I have to do and only breathe again when the power can be re-applied.
Are you any different? Anyway, a new technology is emerging which is set to be the next big leap in mobile technology. Not only will it extend charge times, but also enable higher current to be available. No more dimmer screens and scaled-back processors.
Away from computers, maybe this technology can be used in vehicles, boats, aircraft and the endless list of thing which benefit from battery power.

Nanotech promises the first viable alternative to batteries in 200 years
February 14, 2006 Almost everything we use requires electrical storage via a battery - computers, cell phones, cars, personal entertainment devices and much more – and as compelling functionality has increased in the digital age, so too has our reliance on the traditional battery which has changed little since it was developed by Alessandro Volta in 1800. Now, work at MIT's Laboratory for Electromagnetic and Electronic Systems (LEES) holds the promise of the first technologically significant and economically viable alternative to conventional batteries in more than 200 years.
