Please expand a bit more, what reactions are you talking about?
You seemed to have missed my point which is that
E = mc² applies to all reactions not just nuclear reactions whether they be neuclear or chemical. This is down to the mass-energy equivalence, as you give a system
more energy it gains mass and as you
take energy away from a system it looses mass.
Most nuclear reactions don't actually convert any particles to energy,
the number of particles left afterwards is exactly the same as before, the difference is a huge amount of energy has been lost so all the particles effectively have less mass than before.
Particles
don't disappear and get converted to energy; the only way to accomplish this is to annihilate them with anti-matter which itself takes a lot of energy to produce.
Look at the animation of
Deuterium and
Tritium fusing to form helium, notice how there are just as many protons and neutrons before and after the reaction?
**broken link removed**
Where's all the mass gone?
None of it's vanished into thin air.
What's happened is Deuterium and Tritium have fused together to form Helium, a thermodynamically stable element. The mass that's lost is equivalent to the energy released.
Why do you think that is?
The oil companies know the oil will one day run out and have wisely invested in alternatives and if so-called free-energy was one they would have soon invested in it.
This is because people found it was easier to dig up coal, extract oil and gas than to cut down trees, build wind turbines (a technology that was very privative in the early 20th century) and hydroelectric power stations are only useful where people are near rivers.
No such silly law exists here in the UK or anywhere else I know of.
You forget that the US is only a small part of the world.
What about China?
Not forgetting other nations you won't even talk to like Cuba and North Korea.
Do you honestly think that you are the only country where free-energy has supposedly been discovered and is suppressed?
Half the world doesn't care what laws you have or what the your oil companies do. For a good 70 years one third of the world's population was totally isolated for you by the iron curtain. It's a safe bet that even if someone in the US had developed free energy some communist spy would have stolen the technology and used it to crush you.
