Tendril Vision Clock Helps You Save In Electricity Bills

I like the Tendril Vision's looks. And I like it even more because it's real, even while it feels like a spare part for the Enterprise's bridge. The clock connects to the electric grid, giving you real-time consumption information.

The device shows usage information, and also displays the cost of energy during the day, allowing you to run appliances whenever the cost of electricity is lower. [Tendril via Earth2tech via Treehugger]
