Wind Turbines based on Jet Engines

Wednesday, January 27th, 2010

Okay, why didn’t I think of that uh? Well okay, I’m no engineer, but you have to admit it’s a pretty clever idea. Essentially, based on the fact that traditional wind turbines only use a fragment of the potential energy that the wind carries (the video says 50% but I’m sure I’ve read that 35% was the best you could get from off-shore turbines which use larger blades) by dissipating the wind, the jet engine technology concentrates the wind in two combined flows to increase the amount of energy produced. This means their efficiency, compared to traditional turbines is increased three to four-fold.

Unchopping a Tree

The following is a beautiful video put together by the whatismissing foundation, seen on TreeHugger. It’s a beautiful perspective on deforestation which needs to be seen if only for its visual beauty.

Of course Climate Data is available

Tuesday, December 8th, 2009

Reading all the distorted nonsense that climate contrarians (I prefer that to deniers actually) put up out there, you’d think Climate Data is a dark dirty secret that only a selected cabal is able to access, interpret and publish at their own whim to create a worldwide conspiracy (to what purpose, I’m not entirely sure but anyway…)

Well the data is out there, and with the greatest global conference having opened at Copenhagen yesterday, I thought I’d put out a few links for people to check out and make their own opinions.

Climategate or Climategoat?

Thursday, December 3rd, 2009

I’m not going to spend hours debating the last desperate attempts that deniers have pulled just days before the start of the Copenhagen conference because they have “no leg to stand on”. Instead here are some videos that explain better how this is viewed in the scientific community with an adress by John Holdren, the scientific adviser of the White House:

Don’t do it for just one day

Monday, November 30th, 2009

I have a calendar that shows me all sorts of “special days” popping up throughout the year, some are funny (World Toilet Day) while others are more meaningful (Buy Nothing Day) and it got me thinking, if these meaningful “special days” are meant to get us to think about specific issues, why keep it to one day? Make it an entire week!

Okay so perhaps “Buy nothing week” would be hard for most people but why not? If nothing else it would get us to think more clearly about what we spend out money on and how we can save up on things which aren’t really needed. Last week was a real set of extremes as far as spending goes. On the one hand you have “buy nothing day”, which is easy enough to follow but then on the other there’s “Black Friday”, which apparently was a huge day of sale followed by many stores slashing down prices for one day only. Is it not a little paradoxical?

Don’t Demonise Carbon

Thursday, November 12th, 2009

One of the things that keep coming out of the multitude of environmental related blog posts or news articles is a sort of emphasis of how Carbon is a Bad Thing™. You see a lot of “carbon is to blame”, “carbon is evil”, “carbon is the culprit”, “zero carbon” and so on. Now those people know exactly what they mean by speaking harshly about Carbon, but I wonder if the message comes across as intended.

We need to remember that life on earth is first and foremost, carbon-based. From tiny algae to sequoias, from plancton to humans, carbon is our main building block, it’s within ourselves, in the food we eat and in the air we breathe. Carbon is the 4th most common element in the entire universe.

Introducing Severn Cullis-Suzuki

Tuesday, October 20th, 2009

This morning I was going round my usual round of news on Google News, when I came across an article about children raising their voices at Copenhagen. In it was prominently featured a (then) 12-year old Canadian girl called Severn Suzuki who gave the most amazing speech at a climate conference in Rio de Janeiro in 1992.

I was pretty flabbergasted, not so much because I didn’t even know there was a conference of world leaders to discuss environmental issues as early as 1992, but the power of her speech is so moving, you’d think it ought to have made an impact on the then world leaders. Sadly we all know how bad the 90’s turned out to be, from an environmental perspective I mean.

To give you an idea, here’s a video of her speech 17 years ago:
