		<description>@ bula53, Nothing wrong with your physics but must point out that the gas is NATURALLY coming out of the earth at 50 - 300 bar which is more than enough to get it to where its needed. It is then reduced in pressure so that joe bloggs in his house can operate his heating at a safe pressure. All this idea does is to capture the excess energy released when that pressure (which was provided by good old mother nature) is reduced. No extra energy is required to &quot;re-pump&quot; the gas as it is reduced in pressure just before getting to the end user. Check out their website www.2oc.co.uk/ some good info on it.</description>

		<description>@ bula53, well said.  But it makes me sad, realizing again there is no free lunch. I got so excited when I first read this article I went to my bedroom to get my perpetual motion machine which I store under my bed.  But guess what... it still doesn&#039;t work.  Damn friction!  :)</description>

		<description>this is so unbelievably dumb.   I am continually astounded by the scientific ignorance of the &quot;green&quot; community.



ever hear of the first law of thermodynamics? in layman&#039;s terms, it&#039;s a law of physics called &quot;no free lunch&quot; - you can&#039;t get more energy out of a system than you put in, and you in fact always get less due to friction, heat loss, etc.



pipes are (or should be) pressurized to the most efficient pressure to push all the gas or liquid from source to farthest destination.  if you put a turbine in the pipe, you are going to lower the pressure beyond the turbine so the gas or liquid at the end of pipe is no longer pressurized.   So now you have to increase the power to whatever pump is pushing the gas at the source (and thus us MORE energy).   Since both the turbine in the pipe and pump at the source cannot be 100% efficient (nothing is 100% efficient), it means you are actually WASTING energy and HEATING the planet more with your waste heat from friction.



in simple terms:   if your turbine is generating 1kWatt from the gas flowing in the pipe, you are probably taking 2kWatts of energy out of the gas flow (assuming a very good 50% efficiency).   So to make sure that the guy at the end of pipe is still getting some pressurized gas, you need to increase the energy injected at the source to compensate for the 2kWatt loss.   But the pump at your source is only 50% efficient, so it burns 4kWatts to inject the 2kWatts of extra energy in the form of pressure into the pipeline.



In reality the inefficiencies and losses are even greater, so you&#039;d be burning up more than 10kWatts for every 1kWatt of &quot;Free Green!&quot; energy you are getting from this dumb idea..... and guess where the other 9kWatts goes? into waste heat that goes into the air!



the &quot;greenies&quot; need to take some baby physics courses before they destroy the planet.</description>
