Alternative Energy and Fuel News: World's first ever 'Brussels Sprout Battery' lights up Christmas tree

Alternative Energy and Fuel News
Tim Challis's insight:

This article is about the Big Bang UK Young Scientists & Engineers designing a method of extracting energy from brussel sprouts. By putting in copper and zinc probes the brussel sprouts undergo a chemical reaction and create electricity. 

 

The article is quite well ritten but although the idea is very cool, it took 1000 brussel sprouts to power a 8 foot christmas tree so it is not a very effective use of energy.

 

Hopefully this idea about how to can be translated into a more efficent method so that hypothetically we can grow our energy.

Canada’s Great Inland Delta: A Precarious Future Looms by Ed Struzik: Yale Environment 360

Canada’s Great Inland Delta: A Precarious Future Looms by Ed Struzik: Yale Environment 360 | Environmental Science Site | Scoop.it
The Peace-Athabasca Delta, one of the world’s largest freshwater deltas, is facing major change as rising temperatures, a prolonged drought, and water withdrawals for Alberta’s tar sands industry threaten to increasingly dry out this vast expanse...
Tim Challis's insight:

This article is about the Peace-Athabasca Delta in Northern Alberta Canada, and how it is drying out due the oil industry in the north and global warming. The delta is very important for wildlife in the region because many different types of fish and birds live within the delta and the decreasing watersupply endangers many of the animals.

 

I would recommend this article becasue it talks about the affects of the oil industry and global warming on this region of Canada and provides great insight into the problem. Though the article is quite long and has some irrelevant sections it is for the most part a good article.

 

I think the article raises an interesting questions because one of the biggest problems is the excavation of the oil sands to the north of the delta, taking lots of water away. It raises the debate whether to pursue the oil sands that will bring great wealth, or to leave them alone and to protect the delta.

Sustainable Ecosystems and Community News: Clean water filtration: basic necessity

Sustainable Ecosystems and Community News: Clean water filtration: basic necessity | Environmental Science Site | Scoop.it
Sustainable Ecosystems and Community News
Tim Challis's insight:

This article is about the plight of many people around the world who don't have access to clean water. In Kenya many don't have access to clean water and they have to drink unsafe water to live. There is a move to bring water filters to these people without using carbon intensive techniques like burning firewood to sterilize the water. 

 

The article is a good article but it doesn't address how the companies plan on making water filters that aren't carbon intensive widely available to the very poor poulations who don't have clean water.

 

I think the clean water issue is going to be the next biggest issue around the world becasue water is a finite source and people will start to fight over water sources. The ability to get water filters to people for a low cost is going to be very important.
