Flowing Info

Via Treehugger, this application is neat in concept. Use Google maps to locate your house, take advantage of knowing the N/S E/W orientation of the house from the map, then enable an app to calculate the size and cost of a rooftop solar power panel installation and match to local utility info to compute year savings. Unfortunately, they only cover CA as of now. But it's just an example of how the Internet enables the rapid flow of information. And the economists point out the problem of information costs, which the Internet is reducing to nil.
