An Australian company is developing a giant flying saucer that can transport buildings for long distances anywhere in the world.

The airship, dubbed the "SkyLifter", would be able to lift up to 150 tonnes - more than seven times the weight that helicopters are able to carry.

Creators English-Australian Jeremy Fitton and Englishman Charles Luffman hope to power it using bio-diesel fuel and solar panels.

"There is a massive need for this," said SkyLifter's investor relations partner Sam Mokhtari in a phone call from London.
