Qualifying nonprofits and civic-minded organizations hoping to kick things up a notch at their next outdoor party can now kick things up 1,000 watts with Austin Energy's solar trailer. It can generate enough juice to power your lights and your soundstage, with enough energy left over for small appliances, too. The best part? It's free – free as in free of the guilt you'd otherwise have from using a gas generator, and free as in no cost to you. Just be sure to apply at least four weeks in advance.
