Most of my experience programming has been small php/mysql projects for small companies, although I'm considering moving to Java. My education was focused between electronics, computer systems and programming. My real programming experience started in VHDL, and besides web work, I've maintained an interest in PIC microcontroller processing in C, and a new interest in Android, given the exciting convergence possibilities it brings. Being an idealist, I'm a proponent of TDD, design patterns, strict typing and refactoring for the sake of it.. don't tell my boss!

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

comment Closed-system power-generation using waterwheels
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
