According to this article, BMW is moving to develop a extremely sporty hybrid vehicle car.

Apparently, BMW has quit Formula 1 racing to allow it to develop vehicles such as the vision efficient dynamics concept.

The car has phenomenal acceleration, like an M3, and yet has similar fuel consumption to a Toyota Prius.

According to this report, wind is the worlds fastest growing source of power generation with an average annual growth of 29% over the last 10 years.

Apparently, global capacity now stands at 120 gigawatts, roughly equivalent to 121 coal fired power stations.

The article reports that by 2015 there is expected to be 425 gigawatts of global wind power installed.


Methane calthrate, anyone? by Justin Blows

There was an article on methane calthrate – ice containing methane – in a new scientist article a couple of months ago.

burning ice

Apparently there are vast reserves of this fossil fuel and it could be a significant component of the energy mix in the future.

There is concern that rising temperatures from global warming will release much of the methane locked up in the ice crystals – a so called tipping point for climate change. Given this, it is hard to know whether it is in the global interest to burn this fossil fuel – is it adding to global warming or is the methane just going to leak away and be an even more potent green house gas?

I guess it depends on the particular reserve being considered and whether it will be affected by global warming.

I wonder what technology is available to extract this resource? It is obviously a different challenge then oil / coal extraction. There may be a lot of innovation required and new machines and methods for extraction. This presents a great opportunity for innovators in this area – if an innovator invents the means to commercially extract this resource, and patent it, the innovator could gain a significant advantage in controlling the extraction of the resource and thus the commercial outcomes from extraction.

Hate cleantech patents? Look here! by Justin Blows

Not all commentators are fans of the patent system when applied to clean technologies.

Some people like the free software guru Richard Stallman don't like patents

Some people, like the free software guru Richard Stallman, don't like patents

This article contains various opinions as to why the patent system should be changed (or side lined) when it comes to clean and sustainable technologies.

Is it just me or are the views of these academics disconnected from our world –  were it is free enterprise that is charged with developing climate change mitigation technologies?

According to this report, four 500sqm dishes in the form of solar collectors are being built at Whyalla.

They will be able to generate temperatures in excess of 200°C.  Interestingly, this experimental solar plant will have ammonia energy storage technology.

If the plant is successful, then a 600 dish plant may be built.

According to this article, the global financial crisis has affected investment in solar technology.

It appears that the countries, such as China, who are backing solar production are the ones doing the best.
