The average American consumes 3383kwh of energy per year. That's equivalent to leaving the light on in 4 rooms for a whole year. And what if power came at a cost to the individual? For the lamp to work one breaks the top off, dissolves the powder, and uses their own blood to power a simple light. By creating a lamp that can only be used once, the user must consider when light is needed the most, forcing them to rethink how wasteful they are with energy, and how precious it is. Idea #2 – White Goat 
A machine from the Oriental, Co. Ltd. that will convert office paper into toilet paper. It takes 30 minutes and 40 sheets of A4 office paper to create one roll of toilet paper, and White Goat claims to be able to save 60 cedar trees annually. The $100,000 machine is set to go on sale sometime this spring. Idea #3 – Pencil Printer 
Instead of throwing away your pencil stubs, you could always feed them to this concept printer, which will then convert the pencil into "ink" for your document printing needs. It supposedly works by separating the wood and lead inside the printer, which can then be used to print your document. Idea #4 – 3D Food Printer 
3D food printer is designed and being further developed in America by cornell university's computational synthesis laboratory. It doesn't look like a traditional printer; it's more like an industrial fabrication machine. Users load up the printer's syringes with raw food -- anything with a liquid consistency, like soft chocolate, will work. The ingredient-filled syringes will then "print" icing on a cupcake. Or it'll print something more novel (i.e., terrifying) -- like domes of turkey on a cutting board. Visit Unique Business Ideas http://www.lowbudgetprosper.com
