About that metal worker demonstration

It is excellent.  I hoped to do something like that with the theory of global warming.  But words aren't enough.  You really have to show what you are talking about.  How do you show, in a demonstration like this, that man-made global warming ( AGW ) is false?

Perhaps you don't need to really.  Just consider this--- all of the argument depends upon the notion that a gas will trap heat.  Then, to demonstrate this, you would have to show something that shows the unsuitability of gases in general to trap heat.  Gases aren't any good at that, and it is a good thing, because if they weren't, your automobile's engine couldn't run.

What makes the engine run is the fact that gases will expand in the presence of heat.  It will expand proportionally to the amount of heat.  The greater the heat, the greater the expansion.  So, you take a small amount of gas, heat it up in an explosion that takes place in the cylinder of an engine, and that expansion causes a powerful force to push the piston down.  The downward push of the piston causes the crankshaft to rotate, which is transmitted to the wheels of your car, and your car can move.  Without this property of gases, otherwise known as the Gas Law, your car couldn't move.

What happens to the gas when it expands?  It cools back down.  It's a beautiful thing.  By the time it reaches the exhaust pipe, it has already cooled down considerably.  If it hadn't, it would be a fire hazard.

So, considering this fact, which is the Gas Law, how can it be possible then, that gases can hold heat?

It is an absurd contention.

Auto engines aren't the only example.  Take hot air balloons.  If the hot air inside the balloon didn't expand, the balloon wouldn't rise.  That's because as the air expands when heated inside the balloon, it becomes less dense than the surrounding air.  As it become less dense, it is then capable of rising, as a bubble rises in water.  If air didn't expand when hot, the balloon stays on the ground.

Another example?  Fire pistons.  These little gizmos may save your life some day.  They work on the principles of the Gas Laws.  You compress the gas in a tiny cylinder, which makes it HOT.  Hot enough to start a fire.  If this didn't happen, fire pistons would be useless to start fires.  Why does it get hot?  Because the temperature is contained within the gas.  As it is compressed, it is in a smaller region, and thus it has to heat up.  Temperature is proportional to volume.  There's an equation for it--- PV equals nRT.  Where pressure equals p, v equals volume, and n is number of molecules ( moles ), and r is a constant for all gases, while T is temperature.  The equation shows that pressure times volume is directly proportional to temperature.  Thus, as pressure increases in the piston, so must the temperature.  A fire piston!  A beautiful thing.

AGW isn't science.  It is a fraud.
