Pump Up The Heat Pumps

- Adam Clare

Too many homes use dead dino juice for heat, and we need to get every home to stop burning the remains of extinct species if we’re going avert catastrophic climate change. The good news is that we can easily do this by getting rid of gas burning furnaces and replacing them with heat pumps. The video above explains how and why heat pumps are so efficient, the article below answers common questions about them.

In terms of cost, it may take a homeowner about a decade to recoup the price of a heat pump through savings from not using fossil fuels.

“But if you’re getting rebates…. it’s going to take a lot less of time to get your money back out of it,” Cheriex said.

Peter Sundberg, executive director of City Green, says those interested in installing a heat pump may end up on a wait list. In the interim, he says, homeowners can focus on upgrades to insulation and windows to make their home more energy efficient.

Beer Cans for Passive Heating

- Adam Clare

They aren’t just for transporting a yummy beverage, beer cans can be used to create passive heating too. A simple contraption that you can make in your spare time can save you heating costs and help reduce your carbon footprint. A beer can heating system, like the one in the video above, is just a series of cans in a row painted black out in the sun under a casing. The dark cans heat up from the sun and move air through them using basic convection.

A DIY beer can heating system is perfect for a shed, garage, or even using it augment your home’s existing heating system.

The concept is relatively simple. The aluminum cans have both of their ends cut off and are fashioned into a series of long metal tubes, painted black. With a fan at one end, and some fins cut into the tubes slowing down the airflow, the metal is positioned in a way to get heated by the sun as the warm air is pulled into the building.

Thirteen years later, the same old beer cans are still chugging along, helping keep the space warm and heating bills low – about $300 annually, McLauchlin estimates.

“It’s -22 C right now and my furnace didn’t come on today,” he said over the phone in early December.

Heat Your Home By Hosting the Internet

- Adam Clare

As the internet continues its growth it consumes more and more electricity because larger server and data centres are required. Microsoft has come up with a brilliant idea to allow ‘the backbone’ of the internet to continue to grow while helping heat houses and providing a faster internet.

Microsoft has released a research paper that suggests that small data centers be put in people’s home and heat those homes using excess heat from the servers.

The research paper comes at a time where internet properties like Facebook, Google, and Microsoft are building huge data centers housing thousands of servers that simply pump their hot exhaust into the frigid air of Oregon, or other chilly states. There have been a few prototype data centers that use their waste heat to warm the houses in local towns, but Microsoft’s Data Furnaces take this idea to the next step: instead of building mega data centers that are efficient in terms of scale, Data Furnaces are micro data centers that are housed in the basements of regular homes and offices. These Data Furnaces, which would consist of 40 to 400 CPUs (between 1 and 10 racks), would be ducted directly into the building’s heating system, providing free heat and hot water.

The genius of this idea is that Data Furnaces would be provided by companies that already maintain big cloud presences. In exchange for providing power to the rack, home and office owners will get free heat and hot water — and as an added bonus, these cloud service providers would get a fleet of mini urban data centers that can provide ultra-low-latency services to nearby web surfers. Of course the electricity cost would be substantial — especially in residential areas — but even so, the research paper estimates that, all things considered, between $280 and $324 can be saved per year, out of the $400 it costs to keep a server powered and connected in a standard data center. From the inverse point of view, heating accounts for 6% of the total US energy consumption — and by piggybacking on just half of that energy, the IT industry could double in size without increasing its power footprint.

The main problem with Data Furnaces, of course, is physical security. Data centers are generally secure installations with very restricted access — which is fair enough, when you consider the volume and sensitivity of the data stored by companies like Facebook and Google. The Microsoft Research paper points out that sensor networks can warn administrators if physical security is breached, and whole-scale encryption of the data on the servers would ameliorate many other issues. The other issue is server management — home owners won’t want bearded techies knocking on their door every time a server needs a reboot — but for the most part, almost everything can now be managed remotely.
