A @Comic_Con State of Mind: If LightSabers are made of light, they would just pass through one another. Useless for defense.

5 million Legos

I found this life size replica of Luke Skywalker's X-wing at Geekologie.

Weight: 45,979.61 pounds (including bricks and steel infrastructure)
Height: 11 feet / 3.35 meters
Length: 43 feet / 13.1 meters
Wingspan: 44 feet / 13.44 meters
32 builders spent 17,336 hours (about 4 months) to construct

PediPower

Rice University engineering students, Tyler Wiest, Carlos Armada, Julian Castro and David Morilla, aka the  Agitation Squad have developed a  foot-powered generator called PediPower

This was posted online 2 weeks ago but someone already made a better device 2 years ago without any of the extra stuff hanging out. At the University of Wisconsin-Madison engineering researchers Tom Krupenkin and J. Ashley Taylor developed an in-shoe system that harvests the energy generated by walking. See, told ya'.

Wave Energy Science Project

Wave Energy project at Chabot Space and Science Center

This year for the OUSD Science Fair, I made a generator using electromagnetic induction for my project. The process was discovered by a guy named Michael Faraday.  I built my Wave Energy project by having a neodymium magnet go side to side in a tube wrapped with copper wire. I built two, one was about 3ft in length and 2.5ft in width with a mast that was about 6 feet tall.  That was the one I tested in the pool. I generated about 3.12 volts from that one.  The other one was a scaled down version that I used to demo at Chabot. We, me and my Dad, goofed around so it took about 3-4 weeks to build both models. But I won "Most Popular Project"; I was one of the five students picked to have their project displayed at Chabot Space and Science Center and I received a medal. People had lots of questions. Mostly "What is it?" and or "What does it do?". I also taught a high school science teacher about electromagnetic induction; she never knew about it. She said she has been working as a science teacher for 4 years.
