Sure. On the other hand, this should be balanced with some critical thinking, to beware of scams or misguided physics.
The Internet is swarming with self-declared inventors, who claim free-energy solutions. See, for example,
http://www.crank.net/energy.html, for some links.
Of course, it is hard to prove that "free energy" is not possible - but some of the so-called "conservation laws", such as conservation of momentum, or conservation of mass (energy), do seem to be among the most fundamental laws of physics.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
