I have been between a lot of jobs for a very long time. Three A-levels, three incomplete degrees, a handful of very short jobs, and a whole load of hobbies and free time. But no money which sucks! But YOLO, and here I am.

Electronics, programming, (Java, Android, PHP & others) are what keep me going, hopefully I'll find a flexible job where I have value in one of those fields.

I'm planning to find a way to become an electrician without having to do slave labour as an apprentice for years, so have picked up electrical installation theory books and UK regulations and am making my way through those. In the mean time, I have a few ideas for Android apps to tide me over. Wish me luck!

Around 1850 Rudolf Clausius and William Thomson (Kelvin) established the First Law of thermodynamics - that total energy is conserved

Using leverage you can do things like increase the speed/distance, at the cost of the amount of force, or vice-versa. Not both. There will still be energy lost, most of which would be as heat. Using the most rigid materials, and the best forms of lubrication or ball bearings etc would help, but nothing will be 100% efficient. Certainly not above 100%! Physicists have known this for a long time. It is the foundation of modern physics. Without this knowledge, we wouldn't have transistors, or car engines, we wouldn't even have had steam engines.

Impossible. It's like expecting a car's brakes to be able to use the energy to then accelerate the car again; it's not possible, which is why cars use fuel. You can re-use some of the energy, but not all. Certainly not create extra energy. In most conversions of energy, heat is the form of energy that inefficient processes lose it to. Your gears, electronics and the water itself would get warmer (from very slightly to significantly warmer)

To use the energy from flow of water to put the water back, with energy to spare, is creating energy from nothing. That is perpetual motion, which is impossible

Do you mean something which generates energy from nothing, basically?

comment Glass pipe cutting
Part of my income is from cutting and supplying glassware, I want to offer glass tubing. My clients use it for anything from, brewing to scientific projects to art, plus a surprising number of bizarre applications such as replacement parts for old military vessels
