Hands-on work on remote control

Off-the-grid technology can present a problem for operators when it’s also out-of-reach. Toronto’s Clear Blue Technologies Inc. has more than two decades of experience in linking environmentally friendly green energy with the hardware and software necessary to monitor and manage it. The company has worked with Centennial students and faculty several times over the years, most recently on a new piece of technology, the Macaw charge controller, which communicates vital information on off-grid hardware (including solar and wind-driven equipment) to remote operators. Macaw can provide users with a range of information, from functional problems to data on the amount of... Read more

Cool work with hydrogen

A lot of effort has gone into discovering the holy grail of zero-emission fuel — and that’s where the promise of hydrogen comes in. A team from Centennial College, including Professor Md. Ali Tarique, innovation program manager Hassan Haji-Esmaeili and student researcher Harparampreet (“Preet”) Kaur are investigating hydrogen cooling solutions that would allow internal combustion engines to run on hydrogen. Because hydrogen extraction is labourious, their hypothesis is that small modifications to an internal combustion engine would be safer, more convenient and less expensive than producing hydrogen fuel cells. Their specific challenge is to find a way to narrow the... Read more

Take heat, be cool

Take heat, be cool. Sounds like a line from a jazz standard, but it’s also a description of solar absorption cooling — a method of air conditioning that uses the power of the sun, rather than electricity, to operate. Heating buildings through the power of the sun is nothing new, but solar-powered air conditioning seems like a contradiction in terms. In fact, it is merely harnessing the sun’s power another way: it uses water, heated by the sun, to drive the chillers in air conditioners. Not using electricity gives solar absorption cooling a huge advantage, because the electrical grid can... Read more
