Default Alternative Fuels...again

Lightening Speed:

Read my post 3-12-2008 regarding alternatives. Those without scientific backgrounds like to say "New technology!" Problem is, there is no "new technology" that over-rides some of the immutable laws of the universe, namely, the three laws of thermodynamics.

1. You can't make energy from nothing. Otherwise, you could make a perpetual-motion machine.

2. Energy can neither be created nor destroyed...it can only change form. IE, kinetic can become heat, heat can become potential, electrical can become light, light can become electrical, etc.

3. Every time you change the form of the energy, you lose some of it due to inefficiencies of mechanical devices. The entropy of the universe must always increase (another law).

The only true sources of energy on this planet are:

1. Stored chemical such as petroleum or coal.

2. Stored plant-chemical, such as wood, peat, or yes, grains, or even weeds.

3. Stored nuclear in radioactive materials such as uranium and plutonium.

4. Radiant heat/electromagnetic energy from stored nuclear energy in the sun (hey, it's an H-bomb).

5. Wind energy, which is really a by-product of the sun's heat energy.

6. Stored potential energy of water in hydroelectric reservoirs, which is another form of sun energy (heat of the sun evaporated the water, lifting it, so it gained potential energy of height).

7. Wave energy, which is a by-product of the stored rotational inertia energy of the Earth as it spins relative to the moon.

8. Geothermal, which is stored heat energy, most likely from stored radioactive materials in the earth's core (scientists still don't know exactly why the Earth's core is hot).

9. Lightning, (Not "Lightening", which is to reduce weight), which is trapped energy from the release of stored energy of the sun (solar radiation bombarding the upper atmosphere).

The key-word above is "stored." If the energy does not exist in nature, then it is not a "source."

Saying Hydrogen is a source is like saying we can solve our problems by buying batteries. You have to make both of them, and it takes more energy to make than you get out (law #3, above).

So where did all this stored energy come from at the begining of time? Good question. I don't try to understand how the universe goes on forever, either---I just know it does.
