I didn't say there weren't any 6 or 8 seat fixed grips, I said I hadn't seen any with an uplift capacity of 3600p/h (well none actually). I suppose in theory you could put enough fixed grips on a line, and run it slowly enough to achieve that capacity, but I wonder why nobody seems to have ordered one ?
Uplift capacity of a chairlift in persons per hour is governed by number of seats on the chairs and loading interval. Loading interval is basically independent of whether the lift is detachable or fixed grip. I will note that there is at least one detachable chair with dual loading stations, but this is highly unusual. How fast the journey is only comes into play at the end of the day and adds a insignificant number of extra people to the total daily capacity.
My guess as to why there are no fixed grip six and eight seater chairs is that the resorts that can justify these sorts of lifts also have sufficient numbers of people using them that they can also justify the additional power costs.
The issue is that in a much more economically marginal snowsports place like Scotland the additional expense would likely be ruinous. So while I would love to see high speed chairs all over in Scotland even if I where to win £100 million on the Euro Lottery and was throwing cash at the Scottish ski centres I am sufficiently realistic that there would be no money for detachable chairs. Though my hybrid concept would likely get an outing :-)
I also asked if you could provide a reference to an actual real world comparative exercise on the cost power input to a fixed vs detachable (you know, where a real operator has done the maths before selecting a aperticular option).
I can't but that is a total red herring. The detachable has to use more power, it simple physics. If you believe otherwise challenge my physics.
As to being a delusional fool, I understand that insult is the last riposte of somebody losing an argument. Personally, i won't stoop to insults in a civilised discussion.
There is no room for discussion, it's like talking to a conspiracy theorist or pseudo science proponent. If you don't believe that high speed detachable require more power then you don't believe in basic well proven physics and engineering. One cannot have a rational discussion with someone who does not believe in well proven physics and engineering. In my book people who don't believe in well proven physics and engineering are delusional fools at the very best.
