If we have a 1 pound Satellite with Solar Sails orbiting the Sun reflecting Energy through Solar Pressure from the Sun at a safe distance, (How much would the total Energy be) to reach 50% the speed of Light and (how big would the Solar Sails need to be) to reach this Velocity in exactly 1 Year.(adsbygoogle = window.adsbygoogle || []).push({});

also, Is there any Data on stepping up this process with added EMP's vs. a Highly Diamagnetic Solar Sail?
