Small Algae Canopy Produces as Much Oxygen as a Forest

- Adam Clare

Algae is amazing and as we find more ways to use the powerful, small, creatures we’ll improve our carbon footprints. Already algae is used to clean sewage, clean landfills, and so much more.

This week at the Milan Expo EcoLogics Studio revealed their algae canopy for urban centres. The canopy provides shade while cleaning the air in a very efficient way!

Created by EcoLogics Studio and demonstrated in Milan, Italy, this “world’s first bio-digital canopy integrates micro-algal cultures and real time digital cultivation protocols on a unique architectural system,” with flows of water and energy regulated by weather patterns and visitor usage. Sun increases photosynthesis, for example, causing the structure to generate organic shade in realtime. In addition to CO2 reduction, the canopy as a whole can produce over 300 pounds of biomass daily, all through a relatively passive system that requires far less space and upkeep than conventional civic greenery.

Carbon-Absorbing Material can Clean the Air

- Adam Clare

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.

Puff Shows Drivers How Much They Pollute

- Adam Clare

It’s well known that cars create a lot of pollution and that if we can get more people to drive their cars more efficiently (better yet – not at all) drivers would kill the environment a little less. To help drivers figure out how much CO2 they release into the air some enterprising floks created an app called Puff.
Puff

Puff is designed to let drivers visualize how much pollution they are emitting on their iPhone as they drive. This way drivers can adapt their driving to minimize their CO2 output.

“Puff is attached to the frame of the car or to the tail pipe. The lamp is light weight and thus well below the 50 pounds you can apparently safely hang from the exhaust pipe. The lamp itself is detachable, so you can take it inside with you whenever you leave your car at the curb. (…) The app also logs the drive data allowing you to keep track of various information such as how much total CO2 you’ve emitted during this trip or during all your trips with Puff, what is the average rate of emission, the total number of miles driven and the average MPG. It also estimates how much NOx, CO and hydrocarbons you’ve released into the environment.”

“Nom nom nom” Says the Cement

- Adam Clare

Our good friend algae is at it again and is cleaning smokestacks!

A mixture of hot gas rises out of a flue stack at the St. Marys Cement plant about 50 kilometres west of Waterloo. But not all the CO2-rich exhaust is vented to the open air.

Some is redirected through a 15-centimetre thick pipe connected to the side of the stack. The pipe carries the gas into a high-tech facility where a species of algae from the neighbouring Thames River uses photosynthesis to absorb the carbon dioxide and release oxygen in return.

“It’s a small model of what a big full-scale facility could be,” says Martin Vroegh, environment manager with St. Marys Cement Inc., headquartered in Toronto. The algae project, which went live last fall, is believed to be the first in the world to demonstrate the capture of CO2 from a cement plant.

The idea, Vroegh explained, is to turn CO2 into a commodity rather than treat it as a liability. The CO2-consuming algae will be continually harvested, dried using waste heat from the plant, and then burned as a fuel inside the plant’s cement kilns. Alternatively, the green goop can be processed into biofuels for the company’s truck fleet.

Porsche 918 Hybrid is Fast and Friendly

- Adam Clare 1 Comment

Porsche has created a new car called the 918 that gets 78 MPG and goes from 0-60 MPH in 3.2 seconds. Sorry those numbers aren’t in metric. The car is relatively kind on the environment producing only 70 grams of CO2 per kilometer.

How does a supercar have such range? Well, the 918 Spyder concept is a parallel hybrid just like your mom’s Prius (well not just like). That means the two powertrains, gas and electric, can operate together or separately to motivate the wheels into motion. There are no less than four modes that configure the powertrains for anything from maximum efficiency to maximum performance and everything in between. The E-Drive mode means pure electric power, and the car can reportedly last up to 16 miles on electrons alone. Next up is Hybrid mode, which is just what it sounds like and would probably be the mode for everyday around town driving. The Sport Hybrid mode again uses both powertrains, but tips the needle a bit more towards performance with most power reaching the rear wheels. Finally, the Race Hybrid mode means all systems are go for the lowest lap times possible (Porsche says it can do the Nordschleife in less than 7:30 minutes). There’s an even a push-to-pass button (if only it were that easy) that adds a bit of E-boost on the straights and, of course, regenerative braking is present and accounted for.
