I've not written a lot of comics...but here's one I did, with an environmental theme, for Communities of Tomorrow via the Saskatchewan Science Centre. It appeared (maybe it still does, I'm not sure) in an exhibit at the Science Centre. I don't think it was ever actually printed as a comic per se.
The art work is by Ward Schell, with colors and lettering by Betta Shum. Click on each panel to see it larger. Or
download the PDF version (a bit pixellated, but not too bad).

Download the audio version.Get my science column weekly as a podcast.We can and do recycle all sorts of things. Paper, plastic, glass (OK, that last one not so much right now), Christmas fruitcakes...the list goes on and on.Wouldn’t it be great if we could also recycle the hydrocarbons we burn as fuel? Imagine if you could somehow take the carbon dioxide out of the air, recombine it with hydrogen, and produce new fuels. You could lessen the need for oil and slow the build-up of carbon dioxide in the atmosphere at the same time.It sounds like wishful thinking—but scientists at
Los Alamos National Laboratory say they can do it....

John Tierney of the New York Times
dares to point out the feet of clay of environmentalist legend Rachel Carson, author of Silent Spring. A sample:The obsession with eliminating minute risks from synthetic chemicals has wasted vast sums of money: environmental experts complain that the billions spent cleaning up Superfund sites would be better spent on more serious dangers.The human costs have been horrific in the poor countries where malaria returned after DDT spraying was abandoned. Malariologists have made a little headway recently in restoring this weapon against the disease, but they’ve had to fight against Ms. Carson’s disciples who still divide the world into good and bad chemicals, with DDT in their fearsome “dirty ...

...how about a car that
runs on compressed air?Most importantly, it is incredibly cost-efficient to run – according to the designers, it costs less than one Euro per 100Km (about a tenth that of a petrol car). Its mileage is about double that of the most advanced electric car (200 to 300 km or 10 hours of driving), a factor which makes a perfect choice in cities where the 80% of motorists drive at less than 60Km. The car has a top speed of 68 mph. Refilling the car will, once the market develops, take place at adapted petrol stations to administer compressed air. In two or three minutes, and at a cost of approximately ...

It sounds promising, at least:A Purdue University engineer has developed a method that uses an aluminum alloy to extract hydrogen from water for running fuel cells or internal combustion engines, and the technique could be used to replace gasoline.The method makes it unnecessary to store or transport hydrogen - two major challenges in creating a hydrogen economy, said Jerry Woodall, a distinguished professor of electrical and computer engineering at Purdue who invented the process.

this one runs on compressed air.Not only that, it's on the verge of production.

A Swiss entrepreneur says his thin-film solar panels will
provide power more cheaply than fossil fules within five years:Even though solar technology has made significant gains since the 1970s when it cost $100 per watt (now it's $3 to $4 per watt), that sweet spot of beating out fossil fuels is $1 per watt. Swiss entrepreneur Anil Sethi says his solar foil can hit that magic number for even less than that — $0.80/watt — within five years and beat the cost of fossil fuels by 50% in 10 years.These thin films can be attached to the sides of buildings and work even on cloudy days.Sounds promising!

The surface of our planet is nice and cool. (A little too cool, this time of year.) But not all that far beneath us, it's anything but. In fact, says Chris Marone, Penn State professor of geosciences, enough heat emanates from the interior of the planet to make 200 cups of hot coffee per hour for each of Earth's 6.2 billion inhabitantsThe Earth consists of three concentric layers. We're on the crust, hard and thin (from 10 to 100 kilometres thick). Under that is the mantle, made of molten rock and about 2,900 kilometres thick. At the center of the planet lies the core, consisting of an inner part about the size of the moon that is essentially ...

We don't hear a lot about geothermal energy in discussions of alternative, environmentally friendly energy sources, but
maybe that's about to change:A comprehensive new MIT-led study of the potential for geothermal energy within the United States has found that mining the huge amounts of heat that reside as stored thermal energy in the Earth's hard rock crust could supply a substantial portion of the electricity the United States will need in the future, probably at competitive prices and with minimal environmental impact.Some early research into geothermal energy was done right here at the University of Regina. Here's the pertinent sidebar from my book A Safe and Prosperous Future: 100 years of engineering and geoscience achievements ...

A very funny
video from Penn & Teller--as their crew has absolutely no trouble getting people to sign a petition to ban dihydrogen monoxide. All they do is tell the truth about this dangerous substance that "leads to increased urination" and "is found in reservoirs, fruits and vegetables, and even baby food."Dihydrogen monoxide, of course, is water.A strong argument for not jumping on bandwagons and maybe, just maybe, educating yourself before making a decision on what to support or not support.
