Gas Mileage: 56 Espressos to the Mile to Office Toilet Paper

All sorts of inventions are appearing around us, and some of them are quite bizarre. I find that the strangest inventions are being made to encourage sustainability and to turn our world more eco-friendly.



Take this machine for example. Invented in Japan, this is an ordinary office paper shredder with one twist: it turns the shredded paper into toilet paper! According to DigInfo, using this machine will save up to 60 cedar trees annually. I wonder if this is worth the chafing I'd imagine that comes with wiping financial reports.



Let me introduce you to the "Car-puccino". Yes, it is not enough that the American people run off of coffee, but our cars are picking up the bad habit as well.

This 1988 Volkswagen Scirocco is altered to run off of used coffee grounds. The system in the car converts the grounds to flammable gas, needing to stop every 40 to 60 miles. Granules are added to clean out the coffee filters which are accumulated with soot and tar.

Coffee mileage? 56 espressos per mile.

According to Nick Watson, "The brand doesn't matter." The coffee just needs to be extremely dry and in pellet form, allowing air to pass through while it burns.

Now that's eco-friendly.
