8. Nest

We can guarantee that you've never thought twice about your thermostat. You're not alone. Most people have a reactionary relationship with their thermostat. They interact with it when it's too cold or too hot, which is a shame because thermostats play a big role in most people's monthly expenses. The Nest, designed by a former Apple employee, looks to change all that by making people want to interact with their thermostat. It's beautiful, but it's also smart. The Nest can build a schedule around when you're in your home and when you're sleeping and when you use the most energy and any other variable that goes into deciding how many energy output is needed for your home. Hopefully every other thermostat maker wakes ups and tries to compete.
