Whole House-Off Switch by Jack Godfrey Wood
As means of reducing wasteful electrical consumption, Jack Godfrey Wood came up with a design concept for a switch that simply turns off your whole house. Well, maybe everything that doesn’t require a constant electrical source.
This product acts like a hub for all your non-essential circuits so you can easily flip off everything but a few circuits for your needy appliances and electronics that require a constant electrical source (refrigerator, clocks, etc). In doing so, it turns off any of the lights you may have forgotten about.
This product is not yet available for purchase and doesn’t appear to have a specified release date. Alternatively, you can opt for a much more complex wireless home automation system. These systems can provide a similar service through the use of radio frequency switches. I believe that a device like this should be installed into all homes to help remind people of their consumption.
