Ski Lift Running on Solar Power
Started by User in Switzerland, 93 Replies
The point about diesel v solar is that after 6 years, you Brucie, are paying for your diesel, bio or non- bio, and have to buy your lift pass, whereas Ally has recouped all of her investment, and is then skiing for free. Every year. -)
The neat app here is that a ski lift is a daytime usage, which is just what solar is made for.
there would be some maintenance, but it is minimal, c/w say turbines. The performance degradatio would be effective after 20/25 years.
Solar costs have fallen significantly since China took up manufacture in a serious way, they are really tops with their research too.

This is an interesting piece of engineering. To understand it, look at Swingbeeps http://www.bmf-ag.ch/media/SolarWings.pdf
Scroll to page 13. The Rh pic shows the support cable and the tracking cable, ie, a motor pulls at one end, and the panels change angle, in a single plane. At 100% sunnyness, the output is 200 Kw for a 1Kw motor power. When it is snowing, I suspect that the motor pulls the tracking cable such that the panels are lying in a vertical plane.
By using cable supports, the cost of individual foundations are avoided
I'm desperately trying to finish a bathroom installation at No 2 son's house, so that I can go ski Cairngorm in June. - )

It may be a fair guess that if you allow skiers onto the funicular, then you are contracted to provide the full first aid/ambulance/recovery/doctor/mountain service, that is over and above normal moutain service. In addition to this, ski school, ski hire, car park, etc. It is uneconomic. It has happened to me in Europe.

If you elect to skin up, you are more of a mountaineer!!

Super Glue is brittle, has temperature limits, and is susceptable to impact.

I witnessed a kilt-wearer attempting to go through security at Munich. The sporran was off, along with the Skean Dhu, the Prince Charlie, Belt and dance shoes.

Hans ordered the removal of the kilt. A quick word in his ear by said kilt wearer resulted in a change of heart.

Obviously, a true Scot!
