Free Flowing Hydro Power

- Adam Clare

TreeHugger has a post up that serves as a good reminder of all the tidal power generators that are being built in North America right now. Including Ontario’s announced tidal wave power feasibility study.

The Cornwall Ontario River Energy Project – 15 Megawatts
The province of Ontario is investing C$2.2 million into a project to demonstrate the feasibility and commercial viability of using free flow turbines to harness some of the St. Lawrence River’s kinetic energy and turn it into electricity.

This project is for 15 megawatts, enough to power 11,000 average-sized homes, but Verdant estimates that “there is enough potential power in the water currents of Canada’s tides, rivers and manmade channels to generate 15,000 MW of electricity using its technology”. That would be about the equivalent of 15 big coal power plants.

But we have to wonder… Did they pick Cornwall just because they could make a really cool acronym? The Cornwall Ontario River Energy (CORE) Project.

LED Cycling Jacket is a Winner

- Adam Clare

I have lights on my bike and I’m a safe rider; however, there is always room for improvenment. An inventor has created a jacket for cyclists that uses LED lights. The lights communicate to other cyclists and most importantly car drivers what the cyclist is doing. The jacket recently won an international design award. The BBC has the scoop.

The jacket uses an accelerometer to sense movement, changing the colour of LEDs on the back from green when accelerating, then to red when braking.

A tilt switch in the jacket also makes LEDs in the arm flash amber when the wearer lifts their arm to indicate a turn.

Take a Greener Vacation

- Adam Clare

Vacations vary greatly on the impact that they can have on the environment. Backpacking in the woods would cause significantly less carbon to be produced than flying halfway around the world. Here’s five tips to make your vacation more environmentally conscious.

The list is clearly focused on Americans, but this is one that can apply to the planet:

4. Find A Green Hotel

This may seem like a monstrous task, but it’s not– check this registry of environmentally friendly hotels. They’re standing ready to assist in your eco-escape, conserving waste, and committed to reducing their toll on the planet.

Put Your Fridge Outside

- Adam Clare

I’ve always found it fascinating that in Canada we don’t have a system in our houses that use the naturally cold air outside (during the winter of course) to cool our fridges. I’m not the only one who has wondered this.

World Changing has wondered this as well:

“…designed to provide such free cooling for walk-in coolers, freezers and cold storage warehouses. The system utilizes an electronic controller to finely tune the operation of standard refrigeration equipment, and this controller simply monitors the outdoor temperature and desired temperature settings and stops refrigerator evaporator fans when not needed, which also reduces the compressor’s refrigeration load. Proper airflow is maintained when the evaporator fans switch off by operating one or more energy-efficient circulating fans.”

Amsterdam Wants to be Known for Sustainable Transportation

- Adam Clare

Like a town in Sweden, Amsterdam wants to be known for it’s greenness. The city council has decided to show the uniqueness of their beautiful city by being the exemplar of sustainable transportation.

The Netherlands – Amsterdam, the world’s number one cycling city with some 60% of all trips in the city centre made by bicycle, wants to turn into the world’s centre of expertise on sustainable mobility. A program to reach that goal was launched on Tuesday.

Amsterdam City Council and various Amsterdam businesses and organizations have joined together in a platform for sustainable mobility: Amsterdam Cycling to Sustainability. A declaration of intent was signed on Tuesday 1st April by Councillor Tjeerd Herrema and the initiators Jos Louwman of MacBike and Pascal van den Noort from Vélo Mondial. Prominent Amsterdam businesses and organizations such as the RAI association, JCDecaux, the Amsterdam Innovation Motor, the Fietsfabriek and Mister Green, also signed the declaration of intent.

Sustainable mobility will ensure that Amsterdam maintains its accessibility and quality of life. Amsterdam is on the right path. Bicycles are widely used in the city and there are all sorts of positive initiatives in the field of sustainable mobility. There is, however, a lot still to be done which is why the Amsterdam City Council and various Amsterdam businesses and organizations are working together to promote sustainable mobility in Amsterdam.
