Grist did a quick profile on it and, if you're interested, a 7-minute video follows as well. A bit pricey ($5,495), but about as low impact as travel can be.
Specs in a nutshell:
And it is not just Minnesota’s government building momentum around an alternative energy future. The state’s Fortune 100 companies, such as Target and Best Buy, have set significant GHG reduction goals. Its power companies continue to expand renewable generation, including both solar and wind. And Minnesota’s civil society, pillared by organizations such as Great Plains Institute and Center for Energy and Environment, helps facilitate change and drive innovation in the energy and efficiency sector. That is why RMI was excited to support the Minnesota Department of Commerce in the development of a comprehensive guide to conducting an energy future study for Minnesota.You can imagine that somewhere in the faraway, fictional land of Lake Wobegon, solar panels are appearing atop barn roofs and wind turbines are gracing ridge lines.
The conclusion: our "business as usual" approach cannot be sustained and governments, corporations, and consumers need to adapt and change to keep our worldwide civilization intact and functioning.
In terms of the environment, LEDs definitely bring some benefits, the biggest of which is energy savings. The Oakland Streetlight Conversion Project will save the city nearly $20,000 per year in energy costs, and will reduce city greenhouse gas emissions by approximately 40 percent (or 80,000 pounds) per year. “The overall goal of this whole project was to have better light in our city streets,” says Kristine Shaff, a public information officer with the City of Oakland. “And the energy savings are tremendous.”
When Sean Fridley, the facility’s Station Manager, looks at the Upper Reservoir perched a thousand feet above his office, he doesn’t see drops of water. He sees a thousands-of-megawatts-deep block of power, a huge amount of stored potential energy — with more output than the Hoover Dam — that he can turn on with a flick of a switch.Other innovative storage methods have been suggested, all based on proven technologies. A promising plan was presented in Scientific American in 2007 involving collection of solar energy in the US southwest desert, with distribution over high-voltage DC transmission lines to compressed-air storage facilities around the country. The current cost of compressed-air storage is roughly half that of lead-acid batteries.
