Is Your Gas Leaking?
What does natural gas smell like? If you said, “rotten eggs,” think again. Natural gas is completely odorless. The stink that alerts you to a leaky stove or bad connection on the barbecue grill is an additive. The sulfur-based additive is put in natural gas on purpose, to avoid the countless deaths and destruction that undetected gas leaks would otherwise cause. But the sulfur additive is poison to fuel cells. Currently, fuel cell manufacturers have to use a filter to remove the sulfur compound.

Removal is inefficient: why add a thing just to take it out a…

While bike enthusiasts in most urban areas continue to have to fight for their place on the streets, Detroit has the potential to become a new bicycle utopia.

Comet trialling free EV charging
Every time we talk about electric vehicles (EVs), nay sayers always bring up the question of range – after all, how can a car with a range of 100 or 150 miles hope to compete with the internal combustion engine? Of course, advocates for EVs argue that the vast majority of journeys are short trips to work or to the store that can be achieved on one charge, and with a little investment in charging infrastructure that range can be extended further. T…

A vegetable garden outside Istanbul’s thousand-year-old city walls.

In the shadow of Istanbul’s old city walls, enterprising urban farmers have carved out small plots of land to grow vegetables, adding a welcome bit of greenery to the roadside as they make, or at least contribute to, their own livelihoods. Green-thumbs in the capital city of Ankara once had a similar opportunity — before the land started being sold out from under them….

Before: how not to grill–high flame, smoke and charring. Photo via flickr by (appropriately) Combust

When barbecuing your free-range meats and line-caught fish this July 4th, be sure to whip up some marinade first. Yesterday, I offered ten ways to avoid carcinogenic HCAs and PAHs when grilling (or any high-heat cooking, for that matter). Thanks to a comment from a reader, I dug digger into tip # 4, the marinating suggestion that lessens HCAs, and discovered some compelling results and recommended recipes for significa…

Those prices are in Yuans per liter, I think.

Fuel Subsidies Punish Virtue
The Chinese government has recently decided to raise fuel prices by about 10%, the third increase in the past few months, following a 6-7% increase on June 1st, and a 3-5% increase in March. The stated goal is to bring the price of fuel in China closer to what the market price is. From a green point of view, this is good because subsidized fossil fuels only encourages waste, over-consumption, and the buying of vehicles that aren’t fuel efficient. It also artificially reduces the competitiveness of technologies that aren’t based on fossil fuels, slowing down their adop…

Perhaps that title is becoming common from those of us who’ve been fighting for clean energy for the U.S. instead of the same old dirty fossil fuels, but as chants of “Drill, baby, drill!” continue to emanate from some corners, we must stick with it.

The Incredible Shrinking Sheep!
Could the changing climate be shrinking animals? That seems to be the case for the Soay sheep of Scotland. “The island of Hirta, on the western coast of Scotland, is home to a special breed of sheep. Soay sheep, named after a neighbouring island, are the most primitive breed of domestic sheep and have lived on the isles of St Kilda for at least a millennium.” These sheep are already smaller on average than other breeds of sheep, but according to a recent study, they have been getting even smaller……
