1. The solar-powered calculator. Every math student and office in the country needs one, so why not make it solar powered? They come in a variety of styles, including handheld, desktop, scientific, and yes, even chocolate scented.
2. The solar-powered flashlight. Sound like an oxymoron? Not so. Solar-powered flashlights charge during the day and hold their power overnight. We like BoGo Lights: Through a “Buy one/Give one” program, each flashlight purchase results in another one being sent to a domestic or international aid program.
3. The solar cell-phone charger. And iPod charger. And laptop charger. And digital-camera charger. Universal chargers like Solio’s Magnesium Edition come with a mix of adapters, making renewable power a snap for all your accessories.
4. The solar bag. Solar packs look like regular bags, but with integrated photovoltaic cells. Not only do they look good, but you’ll never have to worry about a dead cell phone or iPod again! Our favorites include Reware’s waterproof Juicebags, which come in several colors and styles, including daypacks, messenger bags, briefcases, and totes.
5. The solar water heater. In many developing nations, constructing water storage tanks and hoses from black materials provides a simple, cheap, and effective way to produce hot water. For campers, solar-heated shower bags are a welcome convenience when out in the woods
