Green Reads has launched a crowd funding campaign on IndieGogo
to build 15 eco-friendly, used book vending machines.
Invented by Dana
Clarke, the machines require no electricity and they’ll allow libraries,
charities, and book retailers a way to sell used books and create a
sustainable source of revenue.
Green Reads is looking to raise
$75,000 ($5000 per machine) by May 19.
Once operational, the machines
will be donated (not sold) to libraries and charities.

more information and contribute to this worthy campaign right here.
