niche, maybe. elitist? hardly!

I like this and it's certainly inventive, but it somewhat reinforces the elitism that many find in green products. <br><br>This is only of use to a select few: those with the money and time for smart phones and micro-blogging. While every bit of awareness helps, <i>very many</i> people are left out. I think, though, that its basic idea has a lot of potential in broader applications.

Yay! 300th vote :) GL Limor.

published code, schematics and assembly instructions are at http://www.ladyada.net/make/wattcher thx!

This is a great project and I actually tried to convince a buddy of mine to look into something like this a couple months ago. Does anyone know when the source and schematics will be published publicly? Thank you for your efforts!

no fair! you can't post working hardware to a design competition! go get out your photoshop and show us something that defies all laws of thermodynamics/physics/ROI like the rest of the entries. <br> F'ing engineers.

Information is king. Just like how we keep ourself informed with our banks or shares, if we can be informed for our usage then that should make a world of difference. We are psycologically wired to function if the info is constantly feeded to us.

This is a great idea .We are infact developing next generation smart energy solution for consumer as well as for electricity grid. Like to talk to like minded person

This is terrific. Perhaps Mr. Obama should have one of these for the White House. Then we can all see how much juice the feds are really using.

Love this!

This is a great idea for energy efficiency surveyors. They could plug a bunch of these in a home and it would let you monitor in real time what the energy demands are without having to be on site. These will be manufactured.

I like that this project is here-and-now real, ready to start making a difference today.
