Toronto is cool — literally!

Metafilter reports that:
>Toronto’s [Deep Lake Water Cooling System]( was launched today. The system cuts electricity consumption in commercial buildings by 75 per cent by [drawing near-freezing water]( through pipes extending five kilometres out into Lake Ontario. According to the city, the system will save enough power to service more than 100 Toronto office towers or 4,200 homes per year, and it will eliminate 40,000 tonnes of carbon dioxide. Here’s a [public television segment]( explaining the process.

Way, way cool. Literally.

My partner’s energy engineering firm, [Ecotope](, is currently working on a much smaller version of a similar system for the new [Northwest Maritime Center]( in Port Townsend, WA.
