The Earth Awaits is a search engine that tells you where in the world you can afford to live, given your budget. The site's creator is a Silicon Valley engineer with a sideline blog about thrifty traveling, a blog which itself grew from a plan to eliminate debt, save every penny, and retire at 40 to travel the world. Readers were particularly interested in the retirement part, and blog posts on the cost of living in various cities proved popular. But blog posts go out of date, so the anonymous authors built a search engine to do the job.
