Most of the micro projector’s that are currently for sale are in one way “wireless” – most will run from batteries, with video coming from an SD card or a  mobile phone, ipod, iphone or netbook / laptop – but this will only last so long (currently some of the better micro projector batteries last 3+ hours) but there will come a time that this draining of a battery is too irratating. What if you want to watch an EPIC film thats 3 hours and 30 minutes? yeah then you will need to plug in your micro projector just like any other projector. There’s little point being so mobile and handheld if you need to have a power cable tying you to a wall. 4 hours charge (at a push) is alright but micro projector’s need much more battery life/an alternative power source.

We talked last week about the possibility of combining the micro projector with the nuclear battery – this is a good idea – despite the propaganda surrounding nuclear power, a lot of weight of the power development is heading down the nuclear route, all be it nuclear fission not degrading nuclear materials. It will just take a time to get these small devices realistically powered by a nuclear battery.

So maybe we cant have a truely mobile micro projector just yet, or can we? Enter resonating power sources like QI Chargers. Using two matched magnetic sources power can now be channelled realistically, feasibly and commercially from central power units through the air into small and mobile devices. This type of charging is not new, resonating power has been around for over a decade, but now with several feasible chargers available at market the likelihood we will soon see resonating power-powered gadgets is increasing every day. Imagine being able to walk around your home with a micro projector that is half the size of current ones (a large part of the current devices is batteries) that has no cables and never runs out of charge, the only slight annoyance is after 20k hours (thats a long time) you may need to buy a new one (as if you wouldn’t replace it in the mean time.)

Of course straying from the house you may need to use a battery pack, that is until we have power available wireless like open wireless broadband. This is a great development technologically as over 40 billion batteries are land filled each year – and whats more it makes the gadget’s more useable – why put batteries in your mobile phone, camera, phone, remote control or micro projectors? when the power can be transmitted wirelessly!

I give it 5 years and we will start seeing some of these technologies truely utilised. Its a great world and time to be alive! Watch this space for the very first truely infinately (nearly) wireless micro projector!
