Amazon patents battery-less and CPU-less tablet

I tablet they are taking over, concerning the need for a device with a sufficiently large screen to replace a netbook.
How much they are spreading, from the cheapest to the most expensive, is obvious to everyone and even Amazon has entered the tablet sector with its well-known Kindle Fire.
According to what is being learned at this hour, the company would be aiming to perfect a tablet specific and futuristic: apparently the staff of Amazon would be working on a prototype of a tablet without a CPU and without a battery.
Jeff Bezos, CEO of Amazon, would have indeed registered a patent – along with another person, Gregory Hart – relating in fact to a screen functioning as a tablet, somehow connected to a sort of transmitter capable of charging the device and making it work wirelessly.
In short, the heart of the system would be a primary station that would thus power one or more terminals which, in this way, could become first of all cheaper and then also thinner and more manageable.

Remaining in the realm of hypotheses – since the functioning of the mechanism is not precisely known – an objection would naturally arise: depending on this primary base, the tablet could perhaps not be used on the go, for example on the street or anyway outside the home walls where the station that provides energy and data is located.
Furthermore, it is clear that the “mother station” – so to speak – would be entirely managed by Amazon and therefore the new tablets would be even more “Amazon-centric” than the current Kindles.
In any case, it is too early to visualize all the possible scenarios to which these potential new tablets would be linked, but the news is certainly interesting in view of a change in the use of these tools which have now become very present in the lives of thousands of people.
