Team Fortess 2 for Free!

My Favorite Class

So im sure many of you know TF2 is now free to download and play. I had been thinking about getting it for a while but now im glad i waited. Ive been playing for quite a bit and have decided that the Sniper is my favorite class, mostly because its gratifying to drop a heavy who's going bezerk. If anyone wants to play add me on steam at snakeman2058 and send me a message!

Biomass Fuel Cells

So lo and behold I sent another fruitless evening stumbling instead of working and found an interesting alternative energy source. A group of scientists (I cant recall where from but im sure they mention it in the video. Forgive me for not saying "after the jump") have developed a fuel cell that basically harnesses micro-bacteria to break down biomass and pulls the electrons out and into a circuit, thus powering a system. In the below video they demonstrate a clock and an admittedly slow moving robot. Well worth a few minutes and hopefully enough development that cars are measured in mile per steak.
