flyingwallop 5 #1 February 16, 2016 I am wondering, out of curiosity on the destination of my hard earned cash, what the costs of running a tunnel are. Say 1 hour of runtime. I am assuming the main cost is electricity. Why is stopping and restarting the tunnel a no no?? Any detailed info would be of interest. thank you Quote Share this post Link to post Share on other sites
FrancoR 0 #2 February 17, 2016 Indoor skydiving Germany has some data on Energy consuption on their webpage. http://www.isg-group.de/en/products-services/tunnel-products/ So if you are running their medium sized tunnel you would nee 400KW for an hour, you need 400kwh. A good commercial price for electricity in Germany is probably 20cent/kwh so you would be looking at 80€/hours energy cost . Does that help?If it does not cost anything you are the product.

flyingwallop 5 #3 February 17, 2016 Thank you very much. Based on these calculations, my initial hypothesis that flying time in a tunnel is mostly expensive due to power costs is wrong. This is probably a good thing as the power costs are probably the the most challenging to diminish. Can anyone else pitch in to make me understand where all my money is going?

FrancoR 0 #5 February 17, 2016 If you go to their FAQ page you will also find the cost for a windtunnel project to be between 3.5 and 6.5 Million. You can do the math from there but you will need to make a ton of assumptions.If it does not cost anything you are the product. Quote Share this post Link to post Share on other sites
OzzieDave 1 #6 February 17, 2016 A 14ft tunnel uses up to 1000kw (http://aerodium.technology/en/models/models/recirculation/) and commercial energy in the UK looks to be worth 11.5p/kwh (http://www.businesselectricityprices.org.uk/). So if the tunnel ran for 85% of the open hours (8am – 10pm say) at an average of ~ 70% power daily running cost average out to be ~ £80/hr. Add 2 reception staff, ~5 instructors, couple of higher ups (managers/marketing/it staff), cost of marketing, insurance, taxes, building costs, maintenance etc etc I'd be guessing a UK tunnel probably has an operating expense of very roughly ~£300-£350/hr? Just a guess Quote Share this post Link to post Share on other sites
wan2doit 6 #7 February 18, 2016 Do many or any tunnel's provide health insurance for employees - that could be a significant cost. Quote Share this post Link to post Share on other sites
Remster 24 #8 February 18, 2016 wan2doitDo many or any tunnel's provide health insurance for employees - that could be a significant cost. Rule of thumb when estimating manpower cost: take the salary,and add 100% for overhead (benefits, etc...). So double it.Remster Quote Share this post Link to post Share on other sites
JerryBaumchen 1,046 #9 February 20, 2016 Hi wallop, QuoteI am wondering, I cannot answer your question in specifics. However, one opened 4 months ago about 10-15 minutes from my house. It is directly across the highway from the largest, weathiest shopping center in the state; and it is within the urban growth boundary ( that means land is very scarce ). Some how I think the cost of the land ( initial purchase ) and the property taxes are significant. Hope this helps somewhat, Jerry Baumchen Quote Share this post Link to post Share on other sites
