What better way to celebrate Earth Day than with a bit of new cooking technology that lets you slow cook the day away without wasting energy? Dubbed the Wonderbag, this clever little bag is here to save your electric bill.

On first glance, it looks like a laundry bag, spherical shopping tote, or on-the-go ottoman. But, it’s actually a small cooking revolution. Each Wonderbag is an insulated bag in which you can cook anything from meaty stews to veggie curries to rice, and pretty much anything you’d cook in a traditional slow cooker.

Rather than relying on electricity to keep things warm, the Wonderbag employs a heat-retention technique to cook all of those saucy, rich dishes you love slowly but surely. This means your sauces get saucier and thicker, flavors are stronger, and your tastebuds are happier.

Simply boil the food that you’d like to slow cook, place in the bag, and let it stand for as many hours as makes sense for your dish. Make rice in just an hour after 2 minutes boiling on the stove. Cooking a big pot of pulled pork? Boil it for 20 minutes and bag it for 5 hours. Your food is ready to go as soon as you get home!

We love the idea of wireless cooking, especially when it benefits the environment. We don’t know about you, but we’ve never felt totally comfortable leaving anything plugged in and running while we’re out and about.

But wait, there’s more! As if it wasn’t enough to be eco-friendly and portable, the Wonderbag also happens to give back through a Buy One, Give One campaign. For every Wonderbag purchased, a matching one will be given to a less fortunate African family. You can purchase your own Wonderbag for $122 over on Firebox, one of our favorite online shopping sites for unusual items.
