Could we harness the power

If we can harness the power of the sun, we could possibly travel to the nearest star here are a few quotes from the series “ask a scientist “at first, a caveat: even though the actual interstellar journey won’t be as bad you might think, the energy requirements are downright absurd. I’ve crunched a few numbers, and for the trip I’m going to describe, it would take the equivalent of about 100 quadrillion gallons of gas to reach the nearest star; that’s about the same amount of solar energy as hits the entire earth every 7 minutes. And mind you, that’s all supposing that we’re just sending a single person through space in a cardboard box with “spaceship” written on the side. Real spaceships are considerably heavier and would require even more energy,”http://io9.com/5551142/ask-a-physicist-could-you-survive-a-trip-to-the-nearest-star
