That is not possible. According to the law of conservation, energy cannot be created or destroyed, but is able to be transformed into another form of energy.
NO. No system can put out more Energy than is put into it. That would violate the 2nd Law of Thermodynamics. However, a simple machine, like a lever can put out more Force than is put in.
No, that would be a violation of the laws of physics.
It can be converted to thermal energy, but you can't get more energy out than you put in. The two different forms of energy must be equivalent, unless there is another source of thermal energy
A laser emits a beam of energy in the form of light. But to get energy out of a laser, we have to put some in. Depending on the type of laser, there are different ways to do this. What is important here is that the energy put into the lasing medium, the energy that is pumped into that medium to stimulate it, to excite it (the actual term), to induce it to lase, is supplied by an outside source, by a pump appropriate to that type of laser. So the pump, that thing outside the medium that stimulates it to induce it into lasing, is pumping when it is exciting the medium. Hope this was, um, coherent....
I suppose you think of a laser. Depending on the energy put into it, it can be used as a markerpen or even be used to cut through steel up to 2 cm thickness.
No. That can not be done in any system in our Universe.

Laser printers use a laser than scans your paper to put the words on it.
Yes. If you put your hand in front of a laser pointer, you disrupt the path of the laser.
No, that would be a violation of the laws of physics.
No. The oxidation of glycogen yields more energy than glucose. You need to put energy in formation of the glycogen from glucose. Naturally, this energy is released, when you get get glucose from glycogen.
The laser check printing software is more advanced than others due to a tracking laser 'watching' the page for any paper discrepancies and print errors which can be put right before the print is finished.
It means that we would get less energy out of that source than we put into it, so the net result is wasted energy.
Yes
Kerosene releases more energy then ethanol but it is harder to put into engines that run on gasoline already.
