Sting jet will need a new power source

The Hyper Sting would have capacity for 170 passengers and travel at 4,287 km/h (2,664 mph).

Its Barcelona, Spain-based designer Oscar Viñals says it's potentially the next generation of air travel, with speed and power most important.

The Sting will have two ramjet engines powered by a small cold-fusion nuclear reactor that doesn’t yet exist.
