Here is a drink cooler that uses Earth’s natural cooling to keep your favorite drinks at a cool temperature without any electricity. The CoolKeeper lets you store your wine, beer, and other soft drinks underground. It has manual, automatic, and app-controlled models. The manual mode requires you to pull the bottle holder rod out manually while the automatic version relies on a gas spring.
The CoolKeeper comes with a universal, adjustable bottle holder. You can find out more about it on Kickstarter.
