If playback won't get to a section of the score, because you've confused Sibelius with illogical notation, bar numbers stop being shown. The most common reason is using the wrong sort of Line for 1st time, 2nd time etc.
In Selling Off The Nationâs Helium Reserve, NAS projected a 2.6 percent increase in the price of crude helium every year through 2015. This would place the 2013 price right around $69.93/Mcf, and the price in 2015 at $73.62/Mcf. Instead, the increase since 2010 has averaged 6.4 percent per year. At this rate, the 2015 open market price of crude helium would be in excess of $95/Mcf. Despite the fact that Richardson has been quoted as saying a party balloon should cost $100, he has testified before congress saying that âprice shocksâ can be damaging for users of helium.
What are the operating cost of the blimp? The cost to operate a blimp are nominal. Helium can be obtained from a local welding supplier and helium sells for around $100.00 per 250 cuft tank. After the initial helium fill of the blimp, the envelope will periodically need to be refreshed with more helium. Over time some air will displace a portion of the helium causing the blimp to fly heavy. The air can be purged with out completely deflating the blimp using only a small amount of helium. The motors of an indoor blimp run off rechargable NMH battery packs that need only a 120-volt outlet to recharge.
