Really green vending machines
The main idea is very simple - to make the vending machine as simple and cheap as possible, transferring the process of payment to the Internet, abandoning the refrigerator, which wastes electricity, making not only drinks cold, but also chocolates and cookies. Does the client need cold cookies? The refrigerator spends energy around the clock and warms the environment. At the same time, such vending machine can not only be powered by solar panels even indoors, but also become extremely cheap to produce and operate, which means it can be installed anywhere where a classic machine will never pay for itself.
