In a hurry? Late to work because your alarm clock went Benedict Arnold on you and decided not to ring this morning? Then take a page out of Romanian teenager Raul Oaida's book and wire a self-made jet engine to your bicycle! On his first test run, Oaida was able to reach a top speed of 26 MPH. Just think, no more running into work or class and having to recite a litany of sorries to everyone gawking at your tardy ass. Oh the humiliation!

So, you're snowed in your house with two feet of snow and need a way out, but are too lazy to shovel. Luckily, you happened to have a welder, some steel, a bicycle, a 3.5HP go-kart, and some wood laying around. So what do you do? You make a plow to get yourself out!
