Is not the air I take into my lungs and all other human beings and all animals take into their lungs not free? How about sea water in all the oceans free for anybody to swim in if they want to? How about the rain that comes down from the clouds?
So the adage that nothing is free is not...
Solar heat and light are abundantly available and so there should be no talk of wasting any electricity produced by both. With abundant electricity, let's say in the deserts of Saudi Arabia, thru' solar, there should be no problem splitting water into H2 and O2.
Now H2 being a fuel and O2...
Why not Solar --> Electrolysis --> Burn to make steam energy?
Solar heat and light are both available in abundance, especially in the tropics. That being so, why is that no attempts have been made to use Solar-Electricity to split water in large amounts, into H2 and O2 to boil water to produce...
You are right. Thanks, Infinity has no beginning nor end.
Now I realize that no one should think about a dead-centre point when it comes to a spinning/rotating disc/wheel. Even though the linear speed is zero at the dead centre, logically thinking, zero speed is never reached in angular...
Take a liquid passing thru' a pipe. The molecules that adhere to the inside surface of the pipe move very slowly while those outside of the thin film on the pipe move faster. On a solid this could never be.
OK no problem. Let's convert rotational to angular. Won't there be a speed at dead centre which cannot be converted because linear zero speed has reached?
Let's imagine a spoke on a spinning wheel like that of a cart wheel. Now we know and can see that the outermost particles of the spoke have a higher speed than the inner particles. As we get closer and closer to the centre, we know that the speed gets slower and slower.
Here's my question...
