so, idea. <br><br>Step 1: Obtain the power to create 2 or more portals that are linked to each other. (Think like the game portal)<br><br>Step 2: Do that thing Tom did, put 2 portals on top of each other and drop a magnetic object through it, then wrap it in wire.<br><br>Congrats, you've created free energy, saved the world, and established humanity as a galactic super race.<br><br>ALTERNATIVE USE:<br><br>Step 1: Do the same thing, but instead do it in space, forget about the wire, and make sure the object is extremely reflective.<br><br>Step 2: Shine a light from the top portal, facing into the second. You have also accidentally created an infinite light source, avert your eyes.<br><br>Step 3: Drop it in. <br><br>Step 4: Wait for the object to build up a huge amount of momentum from the reflected light bouncing off of the top of it. The amount of momentum given is small, but it will be exponential thanks to the portal fuckery.<br><br>Step 5: Once the object has approached light speed, disable the portals and let the object loose.<br><br>Congrats, you've created a light speed planet destroying cannon. Have fun with it.
