Experimentation of this kind is very multi disciplinary, it requires skills such as electrical & mechanical engineering, physics, chemistry, electronics, material science, microscopy, software, machining to name but a few. Because it is an emerging science and there are no hard and fast guide books, it is about discovery, sometimes fact led, sometimes evidence but often a lot of perspiration and a modicum of inspiration.
People with these skills are not cheap and because the actual physical labs and hardware are expensive and components often bespoke and sourced from all over the globe, the costs for this work is high.
We also have to think about legal issues and the costs of distribution and documenting our effort for all.
This all adds up and we don't want to do half a job as that is no job!
