That's good work Tino. However, given that the current production is limited to zero degrees to +5 degrees, depending on the system, these guys are displaying the art of the possible. my view is that is a marketing mistake, 8 or 9 deg would be useful, where the feed water is likely to be lower than 5 deg.
The impractical point seems to be the size of the plant, implying high ditribution costs.

Now this seems like a more sensible idea for the missing section at Trockner Steg in Zermatt.

In conjunction with the snow making plant to put a top layer on it, it would massively reduce the energy required to keep that section open.

Seems to be a good idea, on the face of it. However, if the ambient conditions caused the glacial erosion, and the conditions do not change, why would new new "glacier" not also melt at the same rate?

Theoretically the can overcome the melt rate by persistantly pumping water whilst there is no natural precipitation and it's below freezing, therefore slowing the rate of decline or overcoming it. Increasing pumping capacity further increases the effect.

When the glacial rock is exposed to the sun, it will absorb & retain solar energy. This heat would be retained, and would gradually dissipate, with cooler night air plus water application.
there would be a time delay for this dissipation to happen. Also, the underlying rock will retain heat.
Solution? C'mon Tino, I will let you have a go.....

Perpetual action of any type will typically result in an erosive effect. Erosion can be positive or negative depending on what you intend to acheive. What the proffesor is trying to say, I think, is that solar radiation errodes naturally formed glacial ice. I dont think I will get argument here. What he professes is that this process takes time, and should one be able to create more ice than the natural environment erodes, then one actually erodes the the effect of natural erosion. There are possibly constraints, as you suggest, however metreological patterns and capacity could be used in tandem to overcome these. After that it is simply man versus nature. Can they create more than nature takes away??
