A Wee Design Flaw

The BrightSource Energy plant, a state-of-the-art solar plant in the Mojave Desert, works on the principal of focusing sunlight on a bunch of towers full of water until the water boils and drives a series of steam powered generators.  Unfortunately, the reflected sunlight also focuses on the areas around the towers, and when flying animals like insects, bats and birds pass through that area, they spontaneously ignite into "streamers", to use the industry jargon.  Possibly as many as two a minute, or 120 an hour, or 2,880 a day, or 1,051,200 per year. So something's gone all fucked up.

And, if anyone has followed the story of this particular plant, they will know that California abused and/or ignored any number of its own enviro laws to get it up and running.

This is something that must be fixed.  The U.S. media coverage, thus far, can be seen hereGreen Power Plant Sends Flaming Avians Falling From Skies!!!  And it will continue, and expand, if for no other reason than interests opposed to renewable energy projects will make sure it does.

That is all.

On Environment Ministers And Petcoke

From Impolitical:

CTV was reporting that Peter Kent may be moving on and therefore would be out as Environment Minister. Not sure there's much a new Canadian minister might do to sway the Obama administration but Keystone has got to be figuring into Harper's thinking. Is Rempel, currently the Parliamentary Secretary to Kent, the one? 

Whoever it is, they're also going to have to deal with this burgeoning - and very warranted - focus onpetcoke. This oil sands byproduct gained greater visibility recently given the Koch brothers' piling of it on the Detroit waterfront to the discomfort of Windsorites looking on from across the river. 

We, for the most part, won't burn it for fuel due to its high emissions levels and the "Environmental Protection Agency will no longer allow any new licenses permitting the burning of petroleum coke in the United States." So it is largely being shipped overseas to China and Mexico, nations that don't care much about emissions levels. Shouldn't we Canadians be concerned about that? Particularly if Keystone were to be approved, with the amounts of petcoke that will be produced. 

Worth noting that one place using Petcoke close to home is Nova Scotia because, basically, its cheap.  In fact that's where part of that big pile is going.  Nevertheless:

Renewables produced 18.3% of [NS's] electricity in 2012, the highest total ever. Approved wind farms to be built and the proposed Maritime Link project would help us reach 40% renewables by 2020 and continue to reduce our use of coal and pet coke.

...which 18.2 per cent figure is considerably larger than, I think, Ontario.  

PS.  Maritime Link is this.  When finished, it will connect the NS power grid to NFLD and surplus power from the  Lower Churchill Hydroelectric Generation Project.
