Heavy-lifting balloons: A new type of balloon may make delivering people and provisions to inaccessible places easier

Heavy-transport helicopters, such as the Mil Mi-26 or Sikorsky S-64 Skycrane, address some of these difficulties, but their payloads are limited to 20 and nine tonnes, respectively, and the huge rotors create a powerful downdraft that makes handling that payload rather tricky.

The company is developing a piloted dirigible capable of carrying loads of up to 150 tonnes over distances as great as 2,000km (1,240 miles) at a speed of 45 knots (83kph). This would permit the craft to transport not just hefty components, but entire buildings, to remote areas. The company envisages modules ranging from rural hospitals and disaster-relief centres to luxury airborne cruise ships.
