Just posted the following on fb, I thought I should post it here too.
Apologies to all, but this damned matter keeps on coming up, time and again. THE reason is to "justify" GH "theory" and AGW, but to explain that is another post. For now, I just want to clear up, once and for all, that a watt can not be timeless, and niether can power figures ever be timeless. Both are tennents that much pseudo-science is based upon.
In physics, power is the rate at which energy is transferred, used, or transformed. The unit of power is the joule per second (J/s), known as the watt
ie power is amount over time.
Therefore a watt can not be timeless. If it is, then it is not a watt, it is a joule.
A joule is an amount of energy. It is merely that.
A Watt, which is a power figure, is exactly the same amount of energy as a joule over a time period, which is by default one second.
Put another way, a watt without time is a joule. There is no such thing as a timeless watt, THAT is why we have a joule....
The following might help people to understand, and by which to remember, the difference between a joule and a watt.
Power is amount over time.
A long time ago it was decided that in recognition of James Prescott Joule and his great works, that an amount of energy should be called a joule. A joule is the amount of energy expended (or work done) in applying a force of one newton through a distance of one metre (1 newton metre or N·m) for one second, or in passing an electric current of one ampere through a resistance of one ohm for one second. It was also decided that we will call the exact same amount of energy as a rate per time unit (by default a second) a Watt in recognition of James Watt's great works.
In short, a joule is an amount of energy, to which time can be added. A Watt is a rate, flow, or power, of the exact same amount of energy, which by default is over the time period of a second, unless otherwise specified. A Watt with no time component is simply an amount (which is a joule), it is not a power figure. Therefore using the term Watt, because it is a power figure, dictates that it is an amount over the time period of a second, (unless the time period is otherwise specified). A watt (which is a power figure) can not be timeless, period.
