Some students at University of Toronto have come up with a win-win solution. They've found a way to combine used coffee grounds, low-quality sugar and wax to make small cakes that burn for 90 minutes. They're contracting with coffee houses for their raw materials and are up for a million-dollar grant. Let's hope they win it.
And speaking of beautiful solutions, there's nothing like a perfect bid. Let us know when you find one!
