Today I went to the pound shop and for £4 I bought four SOLAR POWERED GARDEN LIGHTS which I took home and disassembled easily and had as a result 4 "blue stripe thin solar panels" each of which can generate between 1.9 to 2.4 volts and 10 to 20 milliamps on a fairly sunny day.

By connecting 4 of them in series I will generate up to about 8 to 9 volts and through put through a simple diode in series with the output to (prevent battery discharge through the solar cells when it is dark) and then connect to the internal battery of the kindle.

When the kindle arrives i will then use uhu glue to carefully paste them on to the back of the kindle.

This means I can leave the kindle in the window and never need to charge it again.

The output of the solar panel can be either put through the mini usb or through micro holes drilled in the kindle back or the wires put through various crevices in the kindle and then connected to the Lithium Battery.

It is VERY important the diode is inside the kindle to prevent a fire if the wire to the solar panels get frayed and therefore stopping the Lithium battery short circuiting into the short circuit..

The diode will prevent any current flowing into the short circuit.

LITHIUM BATTERIES CAN CAUSE FIRES.

Don't do this if in any doubt.

I will of course be very careful and use uhu glue to fix everything in position on the inside of the kindle.

A friend suggested i get more solar cells and also paste them on to the front of the kindle on the bezel and the empty area about the keyboard buttons but I thought this as too complicated and ruin the look of the kindle.

However solar cells on the front would mean it charging even when i am reading from the light above, whereas with solar cells on the back this will only happen when the backside is up.

If you are going to do this get the thin stripe plastic encased blueish solar cells as the thick glass ones are thick , heavy and fragile.

We should get Amazon to produce a case with the THIN solar cells already printed on the front and back.

This means even in a zero electricity country or desert island the kindle will always work.

After Word War Three at least you won't be bored.
