Please do NOT flush it down the loo if its a macerator or you may need to harness the unbridled power of an " Eco fan " as a pump to clear the blockage.

..but it goes through my 'Vacuflush' system ok as there is not substance in it at all.

so much for a proper report.  This testing was done in the winter of 2010.

for anyone looking for the report.

On page 9, it says, "The authors intend to design and conduct improved experiments in the fall of 2010 to adequately quantify advantages of using a fan when used with a wood stove. The new experiments will be conducted in a test facility with improved controlled environment that allows for below 0°C settings."

Ah, I see it now. Yes looks like another report was promised

...but this wasnt it. That is just a flyer from the fan makers.

I know, but it is dated Winter 2010!  It's all they offer.  I did email them asking for a full report.

No Mr Ed. Rember the talking horse prog from the US in the later 60's - I think it was in black and white?

Sure you are. You think the Ecofan is effective

Not unless you pressed 'play'. You'll get an earworm!

Just clicked on it. Wow that brings it all back. Wilbur Post! Early 60's. Was it really that long ago?

Wiki says: "While air movement can be pleasant and provide comfort in some circumstances, it is sometimes unwanted and causes discomfort. This unwanted air movement is called "draft" and is most prevalent when the thermal sensation of the whole body is cool. People are most likely to feel a draft on uncovered body parts such as their head, neck, shoulders, ankles, feet, and legs, but the sensation also depends on the air speed, air temperature, activity, and clothing" (my emphasis).

There must be a cross-over between the comfort felt from the convection and the discomfort from the draught. At what air speed would you suggest that crossover occurs?

They missed out humidity. The relative humidity of the air affects how hot (or cold) you feel more than the actual temperature or velocity of the air. 

Think how hot and sticky you feel at say 30°C in a humid country like the UK, rather than say at 30°C in Dubai. This is because in humid air your sweat cannot evaporate readily, but in dry air the sweat evaporates,  making you feel much cooler.

Funnily enough experiments by the military especialy in the USA have been ongoing for many years re this matter. The military needed larger helicopters to move large equipment and many personel and no internal combustion type engines in build were powerful enough for the job. The problem was solved by the top brains from NASA and the Chinook helicopter was born. Powered by not one but two eco fans with a large propeller at each end of the aircraft. Sat at each end under the eco fan is a crew member with a lighted candle producing the required heat source. Early problems were caused by using candles too large for the job and small household candles were eventualy found best for the job otherwise the helicopters used to climb too high and orbit the earth.

Well that is nearly right but a larger heat source in the form of a gas turbine

Two of them, in fact!

It's often not realised that humility is vital when dealing with an Ecofan.

Mr. S did say there were two heat sources

Well for you Sterling engine fans there is one here http://auctions.durrants.com/auction-listing.asp?page=5&aid=433 Item 237 I thought there was a second but cant see it

Pedantry alert:

It's a Stirling engine (after Mr Stirling) not a Sterling engine (like the money)

Get it Right Chaps,it is a STIRRING Engine, it just Stirs the Air a bit

You are ill-informed for a proper pedant!  The engine was invented and patented by Reverend Dr Robert Stirling, not Mr Stirling!
