- Supersonic laser-propelled rockets: New hybrid approach may help power rockets, launch satellites, enable future aircraft to exceed Mach 10
- Microrockets fueled by water neutralize chemical and biological warfare agents
- New solar power material converts 90 percent of captured light into heat
| Posted: 29 Oct 2014 10:34 AM PDT Researchers have described a new system that integrates a laser-ablation propulsion system with the gas blasting nozzles of a spacecraft which can increase the speed of the gas flow out of the system to supersonic speeds while reducing the amount of burned fuel. |
| Microrockets fueled by water neutralize chemical and biological warfare agents Posted: 29 Oct 2014 09:45 AM PDT With fears growing over chemical and biological weapons falling into the wrong hands, scientists are developing microrockets to fight back against these dangerous agents, should the need arise. They have developed new spherical micromotors that rapidly neutralize chemical and biological agents and use water as fuel. |
| New solar power material converts 90 percent of captured light into heat Posted: 29 Oct 2014 06:54 AM PDT A multidisciplinary engineering team developed a new nanoparticle-based material for concentrating solar power plants designed to absorb and convert to heat more than 90 percent of the sunlight it captures. The new material can also withstand temperatures greater than 700 degrees Celsius and survive many years outdoors in spite of exposure to air and humidity. |
