This lovely little video from Nest–The Learning Thermostat, put a smile on my face. And with more than half a million views, it’s yet another example of how eco-centric products can use new media to speed adoption. This is something we’ve flagged as a breakthrough trend: consumer adoption of new energy technologies. Nest sets the bar here by making it fun, easy and aspirational. Thermostats can be intimidating. Nest makes them friendly. See for yourself.
