Environmentalism & Politics

I actually wrote this last year on my other blog but I think it’s still pertinent. What often happens with government is that they focus on whatever the media starts paying attention to. And the moment the public looks away, they go off in another direction. Although the economy is of great concern, so is the environment still and always important. Moreso now when recycling companies are not making as much a profit and therefore it isn’t “economical” for them to recycle or for other places to buy the products.
There has been quite the hullabaloo in the media lately as politicians have woken up from a twenty-plus year hibernation to look around in sudden alarm and go “Oh my, we have an environmental problem.” Hello?

When I was a teenager I wouldn’t litter and a friend asked, oh why bother? I said, well it may only be me today but then tomorrow it might be me and someone else, because they saw me not littering. And the next day there could be three or four, etc. I feel vindicated that at least recycling has become more of a norm (at least in some provinces) than it was in my teens.

And at least by the time I was in my twenties I was reading about the Gaia Hypothesis (how the world is one symbiotic living organism and what you do to it in one place affects the whole) and how our pollutants were wreaking havoc with the world and if we stopped all smog causing agents, then it would take at least fifty years to see any positive results.

In 1998 I wrote for a now defunct e-magazine (victim of the dot com downfall) called technocopia.com. It looked at how new technology was changing one’s life and lifestyle, from cell phones in third world countries to robotic heart surgery. I was researching fuel cells and hybrid cars and came across the Kyoto Protocol. Governments had already signed up for it. So how is it in 2007 various governments have dropped out of fulfilling the requirements and now cry it will break the bank because there’s not enough time? That was ten years of time.

I hear Stephan Dion say on CBC that pollution has just become a problem? What!! Just? Puhleese. I’m not sure what the benefit was to Tony Blair to stand up and start waving the big green flag but it suddenly looked like the cool thing to do and Canada jumped up beside him. George Bush of course is still in right wing crusader war mode. Environmentalism might mean putting collars on his pals, the oil and car companies.

But I’m cynical enough and eyes open enough to wonder why politicians would suddenly go on about this when a lot of us have known there’s been a problem for over twenty years. Well, hmm, minority government. Who wouldn’t want to keep our country green and with air we can breathe? For Harper it’s a surefire way to garner a shiny star on his report card. But it would be much more believable if saving our resources wasn’t done because of political maneuvering and was just done because it’s the right thing to do.

And yet, the Conservatives whine and shuffle their feet and say oh we can’t meet the Kyoto Protocol. Or, maybe we could but it would cost gadzillions and all you poor Canadians that we normally only care about when you’re voting will pay the price. A few weeks ago on CBC, The Current had business leaders from various sectors and they were saying that they were on board with changing and implementing environmentally safe processes and procedures. The interesting thing here was that all of them said that it would be more cost effective and they would probably actually make more profit by switching over. So how is it that the Baird Report says we’re going to have to pay with our first born?

Perhaps I’d almost believe that maybe, just maybe, our lovely government was actually concerned with the environment and not with losing power if it wasn’t that I see this as a big smokescreen. What have polls of recent years shown is the number one priority for Canadians: universal medicare. So why aren’t we hearing more about this? Because it needs a massive overhaul. And we’ve all turned to look at the shiny new green flag being waved so that we won’t notice the huge cutbacks, the ever longer waiting lists, the rampant deadly infections running amok in hospitals and killing people. Because the government can win votes easier with this lovely green beast than with the monster of medical coverage.

I was willing to let go some of my frustration, anger and disgust with the head-in-the-sand attitude various Canadian governments have had if it meant at least something was being done. But then we get the Baird Report; more stalling about actually really doing something.

I’m trying to do my part and have for years. I could do more. We all could. I’d get a hybrid car if I could afford one. What part is the government really doing? Will they put teeth into their policies or leave them to gum the ankles of corporations and groups that continue to pollute? I’ll wait and see.

Saving Energy and Environment with the Power of Fuel Cells

From 1999-2000 I wrote for Technocopia.com run by Hillary Rettig, which unfortunately fell victim to the dotcom drop. With her permission I’m listing some articles here. It’s interesting to note that most countries had already signed on to the the Kyoto Protocol, including Canada & the US who used various strategies to start backing out later.

The Kyoto Protocol, signed in 1997 stated that by 2008 all signing countries agree to lower their emissions of airborne pollutants from cars and industry.  Development and deployment of new technologies must begin years in advance of that deadline for countries to comply.

One approach that some regions are taking is mandating that a certain proportion of new cars sold produce zero emissions.  In the U.S., California, Massachusetts and New York are all calling for zero emission regulations. California will require that 10% of all cars sold by 2004 have zero tailpipe emissions.

Electric cars are one possibility.  Long recharge times on batteries, limited driving range (50-100 miles), and few recharge stations have left the public and car manufacturers less than enthusiastic about electrics as viable clean energy transportation.  

Another alternative is the new hybrid gas/electric cars that use an electric battery and a small gasoline tank. Although these cars have a driving range comparable to gas-powered cars and are self-charging they still use nonrenewable fossil fuels though emissions are lower.

Enter the Fuel Cell

A new contender in the zero-emission-vehicle race is the fuel cell.   DaimlerChrysler and Ford hope to have fuel cell-powered cars on the road within the next few years.  Both are partial owners of Ballard Power Systems Inc. in Burnaby, BC, which is the leading researcher and developer of fuel cell technology.  GM, Volkswagen, Honda, Nissan, and Mazda are also experimenting with fuel-cell-powered vehicles.  Chicago Transit Authority and Vancouver’s Metro Transit authority (Translink) are deploying fuel cell-powered buses on a test basis. The fuel cell uses hydrogen and air, which produces clean water (in some cases, water vapor). It can also be topped up quickly with fuel instead of having to be charged slowly like an electric battery.

A fuel cell is a chemically coated membrane sandwiched between two walls. On one side hydrogen is fed in and from the other side, oxygen. The hydrogen, upon reaching the membrane, splits into protons and electrons. The hydrogen protons move through the membrane to join with the oxygen on the other side. At the same time the hydrogen electrons, which cannot pass through the membrane, move out of the cell and are harnessed as electricity. The hydrogen protons meet with the electrons and the oxygen to form hot water.

Fuel cells sound like the “perfect” technology, but there are some problems that still must be resolved if it is ever to be commonly used in transportation.  These include the weight and size of the fuel cell stack, the fact that hydrogen is a highly volatile substance, and the lack of fueling stations.

Hydrogen can be extracted from other fuels but some emissions are produced. Methanol (known as wood alcohol), is a safer fuel source than pure hydrogen and will probably power DaimlerChrysler’s future mass-produced Necar, as well as other fuel cell cars.

Personal Fuel Cell Uses

Fuel cells are also being investigated for use as a power source for homes and appliances. Ballard’s Mark 900 fuel cell will be the basis of a one-kilowatt generator to power Japanese homes. The generator will extract hydrogen from natural gas.  It would be used during off-peak hours as the energy source and then supplemented by the city’s power grid during peak hours when many lights and appliances are turned on. Japan is eager to switch to fuel cell generators since several nuclear reactor accidents “have sapped the country’s already brittle confidence in nuclear power.” The Vancouver Sun (01/14/2000)  Ballard believes that Japan’s fuel-cell generator will be ready in two years.  They are also looking at marketing the generators for Europe and North America.

In the U.S., fuel cell generators are also being looked at as a supplement to city electrical grids. Many of these power grids obtain their energy from nonrenewable resources. Plug Power in Albany, NY received over twenty million dollars in research grants to develop a fuel cell that could be used in residential homes instead of using the traditional electric company grid. The fuel cell generators might be used to supplement photovoltaic panels, which collect solar energy.  Some houses already running on solar energy only draw on the grid during peak hours, cutting down the costs for household power and electricity.

The subkilowatt world of portable devices, such as laptop computers and cell phones may also soon use tiny fuel cells instead of traditional batteries. Motorola Inc.’s new “air breathing” fuel cell, developed at the Los Alamos National Laboratory “eliminates the need for air pumps, heat exchangers and other complex devices that previous fuel cells required and therefore disqualified them from successful use in small portable electronic products” according to Reuters, (01/19/2000).

The Motorola fuel cell measures one inch by less than one-tenth of an inch, and would last ten times longer than the standard lithium batteries now used, stated Christopher Dyer in The Chicago Tribune (10/25/99). Another two to five years of research and development are needed before the air breathing fuel cell is ready for the consumer. 

Fuel cells may still be the energy source of tomorrow, but that tomorrow is so close that the bus you ride today and the laptop you buy tomorrow may be powered by this clean energy. Fuel cells are one way that will let us all breathe easier.
