Vending Misers are nifty little devices that can be installed on beverage vending machines. Vending machines run very inefficiently. At Tufts, each vending machine costs the University about $380 in electricity costs each year. With a Vending Miser, the electricity consumption can be cut in half. Vending misers cost about $165 and have a pay-back of about 1-2 years.
