More Bad News For JPP's Coal & Oil Shills

In other words...

You AGREE IHA is lying when he claimed wind and solar power will never become more efficient, nor improve their output beyond their current levels.

I agree with this, it is hard to see how you can make wind turbines much more efficient.


The theoretical maximum power efficiency of any design of wind turbine is 0.59 (i.e. no more than 59% of the energy carried by the wind can be extracted by a wind turbine). Once you also factor in the engineering requirements of a wind turbine – strength and durability in particular – the real world limit is well below the Betz Limit with values of 0.35-0.45 common even in the best designed wind turbines. By the time you take into account other ineffiencies in a complete wind turbine system – e.g. the generator, bearings, power transmission and so on – only 10-30% of the power of the wind is ever actually converted into usable electricity.

LOL You don't even recognize what the tricorder did. Try diagnosing disease with your Iphone 7.
 
The "endless oil" thing is just so naïve, scientifically.

With population increase, world consumption is going to be astronomical. I don't think the guys arguing "endless oil" realize that it took millions of years to put together the current batch. It's not replenishing at a rate that will keep up w/ consumption, and once the current batch is gone - even if there is this backup batch that they keep referring to - it will take millions more years to restore what we had.

Oil WILL run out. It may be in 50 years, it may be in 200 - but it is a finite source for all practical purposes. Trying to argue that it's just self-sustaining with population & consumption increases is hopelessly ignorant.

We know that, stop stating the bleeding obvious ffs. I said to all intents and purposes it is endless as there will always be more than enough until 4th gen nuclear MSRs come onstream. Anyway, there are other ways to produce oil from coal and algae. There is also a possibility of using the rotting corpses of brain dead scientific illiterates, they will never run out.

Not at all. And by the way loudmouth here is your link where you clearly state alternative energies break the laws of thermodynamics and physics. https://www.justplainpolitics.com/showthread.php?81327-Renewable-Energy-Sets-Record-in-USA

Look at post # 16 and # 31.

I never said that they break the laws of thermodynamics.

I said that thermodynamics is why they will never fully replace oil, gas and coal

Sorry if you have the reading comprehension of Desh. That is why this is so difficult for you.
 
Rune said:
59% is almost double the efficiency of coal.
Thanks Bravo.

That's the theoretical limit, when you take into account other factors like the mechanical losses due to the bearings and gearbox the efficiency is nearer 10-30%.

I've long advocated turing fat corpses into biofuel.

Look Zippy. All anyone has to do is look up exactly what you said by that link. It is pretty clear. Go whine someplace else.

You are wrong and have the reading comprehension of Desh. Congrats

I have accepted your concession already. No need for you to keep conceding

Who precisely is "we"?

You got a mouse in your pocket?

There are SEVERAL posters claiming oil is indeed a "renewable" energy.

Maybe you should spend a few minutes berating them?

But since we don't pay Saudi Arabia for our wind, put me down as bullish on it. By the way, check this out..... to follow.
 
Found it. Looks pretty good. Low and slow

[video]http://www.businessinsider.com/waterotor-harvest-green-energy-water-currents-2-mph-turbine-electricity-fish-flow-renewable-2017-4[/video]

"No other water energy extraction device has managed to produce an equivalent of high energy while operating in very low water flow speeds, as slow as 2 mph. Waterotor captures consistent and economical electricity, from it’s sealed attached generators, when submerged within ocean currents, rivers and canals.

This unique invention is due to the way Waterotor achieves maximum torque, resulting in a high coefficient of power. The generator converts energy from pure torque moments in contrast to systems with propeller or wing-like blades which require much higher flow velocities to achieve or match the same Coefficient-of-Power in flow speeds below 9 mph.

Water has 830 times more energy than wind thus a small device in water can economically harness a large amount of energy around the clock. Waterotor is an engineering breakthrough, with significant advantages over previous systems. These advantages enable early global market penetration."
