    Solar Cells The primary Solar Cell material is silicon. It converts photons into electricity and the more efficient panels have a multi-layered construction. But it isn’t only the construction that affects the efficiency. There are other factors such as: Angle of Incidence of the incoming light Photon Density in the silicon reflections shading These can…

    Computer Programming In a previous post I referred to Ada Lovelace who has been recognised as the First Computer Programmer and an inspiration to legends such as Alan Turing. However most of her programs never ran on anything. The technology to do it didn’t exist and was too hard and too expensive to make at…

    Computer Programming When we think of Computer Programming, we are generally thinking of electronic based computing engines with code running out of some form of electronic memory and typed in using some form of keyboard. Even punch cards partially fit this paradigm. And they seem ancient now. So would it surprise you to know that…

    Wireless Power Is Coming In a very real sense it is already here in part. Wireless Charging is becoming mainstream. But seriously powering a device wirelessly has been a difficult challenge and there are many who think it will never be effective unless done at power levels that would be unsafe. So it was with…

    Data Storage History The storage medium for data has become increasingly sophisticated over time both speeding up the writing and reading of data and increasing the density of data that is stored so that we can now store on a single device the size of my thumb all the knowledge that existed in the world…
