If Hoyoung Lee’s concept printer becomes reality, you’ll never throw away another pencil stub or buy another ink cartridge. The pencil printer separates the wood from pencils and uses the lead to print documents. There’s even a built-in eraser component that allows you to remove text from a page and reuse the paper, so you’ll be saving money and trees.

I call bullshit on this one. You’d think the inventor would know that pencils don’t have lead on them (it’s graphite), non?
