Years ago in Dubai a zillionair Arab built a snow ski slope in a desert Hotel. It costs him something like $10,000 an hour to operate - and tickets were around $12 a person. Fewer than 20 people could ski at a time. He thought it was a wonderful idea and that indoor skiing would take off.
Reminds me of this battery car thing...
That is a fair comparison, viability-wise.
I’ve seen that ski slope. Never understood it....in a middle of a desert. Fools and their money...About as foolish as Politicians here in the States.
