【Share】Building smart homes of the future
|
||
|
You come home after a long, hard day at work. Having grabbed a frozen meal on the way home, you set it down on the coffee tabled and tum the kettle on. Seems normal, right? Only that your frozen meal has smart packaging and the coffee table has induction coils built in. So that as soon as you set the meal down-anywhere on the table-it starts to defrost the meal and keep it at that temperature. And because the kettle is also powered wirelessly, you can leave it anywhere in the house. The surface senses a kettle has been set down and starts to power it up. The surface is using magnetic fields to heat directly into the metal inside the product, and only the coil, meaning that you will not burn your hand if you put it next to your thawing meal or boiling kettle. That may seem far-fetched, but according to Dave Barman of the US film Fulton Innovations-which makes this cordless induction -heating technology-we could be only three years away from this being a reality if manufactures want it to happen. "It's more efficient than gas and electric," he says. "When installed properly, there shouldn't be any cost difference between the traditional method and an induction zone." Green buildings The smart home of the future, featured in science fiction movies and cartoons like the Jetsons, is almost upon us. While we are not quite at the state of transporters and instant food makers a la Star Trek, our homes are getting smarter and more sophisticated. Real-time monitoring of every aspect of your house is here already, from plumbing to electrics, while companies like Google are trying to get the internet into your TV. But it takes a lot of power to make this happen, and a much more sophisticated approach to home construction, presenting opportunities for a whole slew of companies out there. In the UK, for example, low-energy "green" buildings are extremely uncommon, according to John Alker, head of policy at the UK Green Building Council, an industry body formed by the biggest homebuilders in the country. But this is set to change. The new government has stuck to targets mandating that all new residential homes must be carbon neutral by 2016, with commercial and public buildings to follow three years later. Much of what the Council does now is retrofitting old homes to make them more energy efficient, like making them less leaky. |
