Chinese scientists say coal power could slash hypersonic flight costs
- Experimental engine uses low-cost mix of carbon particles and ethylene to trigger shocks at six times the speed of sound
- Researchers expect the technology to achieve at least 20 per cent higher fuel efficiency than modern jet engines
