SolSource Grill

If you have a hard time reconciling your love for backyard barbecues with your sustainable mindset, then the SolSource Grill ($249) is here to ease your conscience. Not only is it environmentally-friendly, it's also a great grill — it heats up quickly and can cook a large meal in minutes. The average gas grill makes four times the emissions of your home stove, and a charcoal grill more than doubles that. This solar grill makes none, so your next cookout can be entirely guilt-free. Since it doesn't need charcoal or gas to work, you can use it miles away from anything, letting you cook great meals anywhere on the planet.
