Photon Torpedos, Solar Cells, Spaceships and Flashlights.

Oh Michio Kaku, you both crush my childhood dreams and create new, more adult ones at the same time.

I was simultaneously enraptured, and saddened, by this video by Michio Kaku in which he describes why Photon Torpedos and Photon engines are nothing but the stuff of science fiction, and will probably remain that way, at least in the way that we think of them.

Michio Kaku is a science-show staple. You can't have a show on the science channel without having an expert testimony from Dr. Kaku. A lot of his "testimonies" have to do with either validating or debunking (or both) sci-fi "impossibilities", and one of my favorite books by him is called "Physics of the Impossible". 

Picked up in an Airport book shop and devoured by the time the plane touched down several hours later. This book provided much entertainment and scientific fun facts. Now whenever a friend or acquaintance (sometimes even just random passers by) are talking about things like time travel and human cloning and they refer to them as "impossible", I like to pipe up and say something to the tune of :

"NAH UHH!!! YOU'RE WRONG AND HERE'S WHY..."

I make lots of friends.

If you don't already know who Michio Kaku is (you heathen) you need to head over to his blog and check out all of the awesomesauce things he has to say all the time. You won't be sorry.
