Hot Invention Cools Down Environment

A seemingly banal industrial component is a heat exchanger and they can be ridiculously inefficient. What a heat exchanger does is regulate the temperature of machines that have to be kept cool like an industrial sized-fridge.

At Concordia, a doctoral student has created a new device that can make heat exchangers more efficient and thus environmentally-friendly. It’s this sort of advancement that is good for the environment and good for profits so I’m sure we’ll see his heat exchanging technology being implemented sooner rather than later.

The innovation behind Vatistas’s unique design comes from over two decades of research into vortex flows. “Growing up in southern costal Greece,” recalls Vatistas, “I became familiar with the concept of vortices at an early age when my elders would warn me of the dangers of swimming near whirlpools!” Youthful fascination evolved into research passion as Vatistas performed advanced theoretical work into how vortices alter the flow of fluid substances like air or water. He later went on to gain international renown for proving Nobel Prize-winner J.J. Thomson’s 125-year-old theorem on the stability of vortex rings.

But it is on the practical side of things where Vatistas’s work resonates loudest. When Vatistas realized that swirling flow could dramatically increase heat transfer exchange, the commercial application of his research quickly became evident. He then partnered with Valéo Management L.P. to investigate new designs of heat exchangers and received a prestigious Idea to Innovation Grant from the Natural Sciences and Engineering Research Council in support of the work.

Carbon-Absorbing Material can Clean the Air

A new material that is inexpensive to produce is also good at absorbing CO2 emissions in the air. Hopefully we’ll see this material being applied to the medians on highways and other places close to planet-damaging carbon emission sources.

Reporting their findings in the Journal of the American Chemical Society, the team (which includes a Nobel laureate in chemistry) descirbes a new solid material based on polyethylenimine that can be used to capture carbon dioxide at the source–be that an industrial smokestack or a car’s exhaust pipe–under real-world conditions where the air contains moisture.

That last part is important. Previous methods of scrubbing CO2 from the air have enjoyed varying degrees of success (usually under controlled conditions), but none has been particularly effective in the presence of humidity. The new material, which is inexpensive and readily available, has shown some of the highest carbon dioxide removal rates of any material ever tested in the presence of humidity.

China Pushes Green Technology Forward

China has to confront a lot of environmental problems brought forth by its own quick development, and when China confronts an issue they go all out! Renewable Energy World has a quick write up comparing and contrasting China and the USA in how they support green technologies.

The China Development Bank (CDB) is being relentless in its funding of clean-tech concerns. While American politicians battle it out over Solyndra’s collapse and potential loss to the government of $528 million, the Chinese are pumping billions into their clean-tech concerns, knowing full well that some of them will fail. The CDB put more than $30 billion in credit into its burgeoning solar companies in 2010, including Suntech Power, Trina, and Yingli. It recently announced financial commitments to ensure that its fledgling wind industry can join the ranks of GE, Vestas, and Siemens, allocating at least $15 billion in state-backed credit to China’s biggest windmill makers Sinovel Wind Group and Xinjiang Goldwind Science & Technology. And China has plans to invest some $45 billion in smart-grid companies and technologies alone over the next five years.

These investments haven’t gone unnoticed in the U.S., and have been front and center in recent complaints that have claimed that China’s solar industry, for example, has an unfair trade advantage.

Charge Your Phone with the Sun

We’ve seen DIY iPod solar chargers before and now an Ottawa-based company has produced a consumer one. The PowerTrip is a small battery with a USB jack and a solar panel on it.

Enter the PowerTrip, from Ottawa-based Ecosol. In a package about the size of a deck of cards, the PowerTrip houses a battery that you can top up via the usual USB port or wall socket (the plug swivels out from the side), or using the solar panel that fills most of one side. Just sit it on a sunny windowsill.

Like its USB-powered sibling, the PowerStick, it comes with several connectors that will feed devices with micro- or mini-USB ports, and it will connect to Apple devices. A fully charged PowerTrip can deliver five full charges to your smartphone; a microprocessor prevents phone damage from overcharging. I tested it with a BlackBerry, followed by a Kobo e-reader, both of which the PowerTrip handled with aplomb, with plenty of power left over for other devices. A power meter on the side of the battery shows the state of the charge.

See Canada’s Environment in Google Earth

Tides Canada has teamed up with Google Earth to allow the world to see Canada’s precious environment using Google’s technology. Now you can visualize things like the boreal forest and the migration of many wild animals.

It’s one thing to say that the Canadian boreal forest is the largest intact forest ecosystem on earth, Ms. Moore said. Google Earth allows Internet users to “fly in and say, ‘Oh, here’s where the caribou migrate, here’s where billions of birds migrate and nest, here’s where the aboriginal communities live.’”

The Pew project was created in conjunction with the Canadian Boreal Initiative, whose executive director, Larry Innes, calls it a validation of the importance of the forests issue.

“It’s a very visual way for people to relate to an area that, for most of us, is not immediately accessible,” Mr. Innes said. Without Google, he added, a similar project would have been prohibitively expensive and difficult.

Former U.S. vice-president Al Gore has used Google Earth Outreach to depict the effects of climate change. Actor Ted Danson has advocated for the protection of oceans, and actress Sigourney Weaver has narrated a tour of the Amazon. A project that exposed the effects of coal mining on Appalachian mountaintops led to many of the mines being put on hold or stopped.
