Zoo Poo for Energy

- Adam Clare

The Toronto Zoo is looking into using all that dung that they have and turning into electricity to help make the zoo carbon neutral.

Zoo board members heard that a digester big enough to produce 4 megawatts could power the zoo plus 15,000 homes in Scarborough.

The technology isn’t new. It’s used extensively in Germany, for instance. Staff told the board the process doesn’t involve incineration, and there’s no combustion.

It could be running soon and would reduce the zoo’s carbon footprint by 40 per cent, staff said.

The zoo keeps a large pile of animal waste on site, some of which is used as fertilizer. One by-product of a biogas facility could be a higher-grade fertilizer, which De Baeremaeker suggested could be sold.

More Wave Power

- Adam Clare

A new way to catch wave power is really neat: it’s wave power through vortexes.

A bane of Big Oil’s offshore rigs could become a boon for renewable energy.
By tapping the natural motion of slow-moving water, a new hydrokinetic generator could open vast new swaths of the ocean for energy production.
When ocean currents flow over any kind of cylinder, like the long cables that hold drilling platforms in place, small vortices are created. They eventually spin away, or shed, causing vibrations that over time can destroy an oil rig’s moorings.
Now, a University of Michigan engineer who long worked on suppressing this phenomenon, has developed a prototype energy-harvester that can capture the mechanical energy it creates.

This Aussie has created quite the wind turbine!

Power Floors for the Future

- Adam Clare

Floors can generate electricity if we want them to:

Redmond’s unique floor tiles generate electricity using a phenomenon known as piezoelectricity – electricity generated by applying mechanical stress to certain materials like the lead zirconate plates in the POWERleap. When these 2-inch by 1-inch piezoceramic plates are bent, a charge is produced that can be harnessed. Multiply one tile by the surface area of a subway station or even your standard grocery store floor, and you can imagine the amount of energy these tiles have the potential to generate.

In a few years Elizabeth hopes people will be able to pull the POWERleap off the shelves of Home Depot and install it to power their homes. More importantly if we generate our own electricity it should change the way we consume, appreciate and utilize electric power. During our cell phone conversation, Elizabeth pointed out another beneficial feature of the technology. “Imagine a business powered by the people who move around inside it. When the people leave for the day the lights and power would automatically shut down.”

DIY Alternative Energy, Build Your Own Solar Power

- Adam Clare

Ever wanted to build your own energy network? Well, now you can!
This guy made his own solar power unit.

So what is a solar panel anyway? It is basically a box that holds an array of solar cells. Solar cells are the things that do the actual work of turning sunlight into electricity. However, it takes a lot of cells to make a meaningful amount of power, and they are very fragile, so the individual cells are assembled into panels. The panels hold enough cells to make a useful amount of power and protect the cells from the elements. It doesn’t sound too complicated. I was convinced I could do it myself.

I started out the way I start every project, by Googling for information on home-built solar panels. I was shocked at how few I found. The fact that very few people were building their own panels led me to think it must be harder to do than I thought. The project got shelved for a while, but I never stopped thinking about it.
