Using LEO satellites to close the global education gap
D2D Satellites can help achieve Education for All
Recycled Smartphones
And Direct-to-Device Satellites
Lets reduce E-waste worldwide by recycling discarded smartphones, and using them to provide education for the 273 million children without a school to attend. I spoke at TEDx in October 2023 about how the latest D2D or Direct-to-Device LEO satellites, could be used in conjunction with recycled smartphones, as handheld schools, where schools currently do not exist,

Why Geostationary Satellites Cannot Serve the Poles
The answer is because at high (or low) latitudes the satellite is on the hozizon.
This is because the earth is of course round, so seeing the satellite from the ground based satellite dish, lowers as you get further away from the equator.
Therefore you eventually get so far from the equator, that the satellite is on the horizon, or below the horizon.
Therefore the dish doesnt have a direct line of site path to the satellite.

OpenCPI, for non-technical people, is best understood as a way to build and manage modular data-processing assembly lines – especially for radios and sensors – without having to rebuild everything whenever hardware or requirements change. It helps engineers break complex systems into reusable components, connect them into pipelines, and deploy them across different computing environments more reliably. The reason organisations care is not just technical elegance; it’s practical: fewer integration headaches, more reuse, and better adaptability when platforms shift. If you can picture LEGO bricks snapped into a conveyor belt system that can run in different factories, you’ve basically got it. And if you ever hear someone say OpenCPI helps “portability” or “component reuse,” now you’ll know they mean: build once, plug together, and move with less pain.
