But that approach requires huge energy input and high voltage, Zhang and colleagues point out (and so would be prohibitively expensive). Ordinary rocket speed is limited by how fast the combusted fuel can eject exhaust NASA has investigated a plasma engine design that can attain exhaust speeds of 50 km/s. A sail driven by alpha particle recoil, for instance, provides some serious advantages over solar sails, as Wenwu Zhang and colleagues point out in the August issue of Applied Radiation and Isotopes. Novel propulsion schemes have been proposed that could reduce that time substantially. Solar sail propulsion - in which lightweight craft could be accelerated by pressure from sunlight - would be a little be faster, but not by much, taking (by one estimate) 66,000 years to make the Proxima Centauri run. At its top speed of 16 kilometers per second, New Horizons would need almost 80,000 years to get to Proxima Centauri.
