Here are two links I’ve been meaning to blog for the past few days.
The World’s wind can produce more energy than humans currently consume.
Researchers at Stanford Univ. have done an exhaustive yet conservative estimate of the world’s potential in wind power. The conclusion: we can get more than we need, if we just tap the resource.
The map, compiled by researchers at Stanford University, shows wind speeds at more than 8,000 sites around the world. The researchers found that at least 13 percent of those sites experience winds fast enough to power a modern wind turbine. If turbines were set up in all these regions, they would generate 72 terawatts of electricity, according to the researchers.
That’s more than five times the world’s energy needs, which was roughly 14 terawatts in 2002, according to the U.S. Department of Energy.
Gimme the Geospacial Web!
Tagging and “folksonomy” are huge right now, an explosion of meta data, tagging things in Flickr, Technorati, del.icio.us. But what if we extended this idea to provide information about meatspace, the real world? GEOurl is one example of this now, but things could become much more rich.
‘Tag the world’ is sentiment of Mike Liebhold, writing on the O’Reilly Network. Let’s describe our world. Let’s have things like WiFi be contextually aware, that is to say, they contain information about where they are, for those who are nearby. Things like Google Maps are just barely scratching the surface of what Mike is proposing. Combine GPS, WLAN, RFID, mapping servers, GIS info, and embed them in everything. The cyber spills out and becomes real in the physical space. Have a look for yourself.
…we can see the beginning shapes of a true geospatial web, inhabited by spatially tagged hypermedia as well as digital map geodata. Google Maps is just one more layer among all the invisible cartographic attributes and user annotations on every centimeter of a place and attached to every physical thing, visible and useful, in context, on low-cost, easy-to-use mobile devices. In a recent email, Nat Torkington, organizer of the upcoming Where 2.0 conference, said it this way: “Everything is somewhere. Whether you’re talking about assets, people, phone calls, pets, earthquakes, fire sales, bank robberies, or famous gravestones, they all have a location attached. And everything we touch in our lives, from groceries to digital photos, could have a location. From these locations we could learn a lot more about ourselves and build new economies.”
