Dome over HOUSTON
Engineers are planning on using heavy-lift helicopters and a new type of helium filled dirigibles.
HELICOPTERS
Erickson S-64 Aircrane helicopter rigged to carry heavy loads at altitudes as high as 11,000 feet.
DIRIGIBLES
the next generation of lighter-than air-ships will be designed to serve as high-altitude heavy lifters. These modern dirigibles nonflammable helium gas and carry payloads of over 4,000 pounds. under the right weather and wind conditions, the dirigibles aircraft of choice since ther use little fuel and can hover over a work site for hours
APEX VENTS
at the Dome's highest point, an array of hinged panels can be opened to provide ventilation, help regulate temperature, clear humidity or pollution and reduce the load on the dome's air treatment systems. they can even be used to free captive birds.
ETFE
Engineers are using a strong lightweight plastic called ethylene tetrafluoethylene, or ETFE. the triple layered surface weighs just 1 percent as much as glass, won't shatter, can be easily repaired and will gently drift down to earth like a feather if it comes loose from the dome's frame.
