"Bio-based" Search Engines

I am still working on the second part of the focus on algae, and between research, and moving to a new place, I am not finding just enough time to flesh out the article just yet. It will come though!

Instead tonight, I wanted to write an informal entry on a particular aspect of "bio-based" ideas: what anyone can do for environmental protection and conservation. In most of the industrialized world and beyond, internet access is pervasive. I find that I am spending quite a bit of time on the internet be it for email, searching information, social networking or gaming. I am sure others will have their own habits on the internet.

It's easy to forget that each action on the internet actually has an environmental cost associated with it. The computers used to read this blog use electricity. Games can be demanding on the graphics card which if high-end can use even more energy than the CPU itself. Beyond the borders of your own computer, each action one takes puts a certain work-load on server machines located somewhere else. And of course these server machines also consume varying amounts of energy.

With all the talk about carbon footprint, it may not be surprising to find that surfing the internet also has a carbon footprint. Searches especially despite the apparent simplicity can consume a lot of energy - sometimes as much as a 11 Watt light bulb in an hour!

For this reason, I just wanted to introduce two green search engines:

1.) Znout
2.) Forestle

These search engines don't actually use new algorithms that are more efficient or anything. In fact, Forestle is a custom search engine using the Yahoo! search engine, while Znout uses Google. What makes these custom search engines green though is what they do with the revenue generated by searches.

According to the website, Znout stands for "zero negative output" and is a CO2 neutral Internet search engine that turns your web searches into green web searches by keeping track of energy usage, and carbon foot-printing and off-setting these by buying renewable energy credits at the end of each month.

Forestle goes a step further. In addition to purchases of renewable energy credits, Forestle uses ALL the revenue minus 10% for administrative costs by donating the remaining profits to The Nature Conservancy's "Adopt an Acre" program.

Because the search engines are based on the two main search engines - Yahoo! and Google -, the search results should be very familiar. Switching to these search engines is easy. They even have a search plug-in feature so that you can search from the comfort of your browser.

Anyway, give these search engines a try, and help save the environment while searching/browsing the internet with them.

Focus on Algae - Part I: Bioremediation

After spending the last few blog posts on different aspects of dissimilatory bacteria, I want to switch the focus to a different class of organisms I have been interested in for a long time now. These are the algae. Algae comprise a large diversity of "sea weeds" and an even larger variety of single-celled organisms that mostly are capable of doing photosynthesis. They include the ordinary sea-weed, and make up a portion of the green slime found around the edges and the bottom of a pond. More exotic types of algae can live symbiotically - that is together with another organism in a mutually beneficial way. Lichens are an example of symbiotic relationship between algae and fungi. More information about the evolution and lineage of algae can be found in this wiki article.

Typically, these organisms are either not mentioned at all or only in conjunction with toxic algal blooms. But lately, algae, of course, have been in the news recently because of the promi…

Sustainable Living: One man's trash...

Since Earth Week is starting tomorrow, I wanted share with you some concrete ways of how individuals like you and me can make an impact on a wider scale. I then also wanted to use this example to challenge everyone to think creatively about the larger context.

So you know how the saying goes: "One man's trash is another one's treasure." Today, I want to talk to you about garbage. Plastic garbage specifically. Plastic is quite a wondrous material. Made from oil by man with just a few additives can turn this polymer into so many different sorts of plastics with so many different properties from thin and flimsy plastic bags, to the carpet on which I am standing, to this plastic bottle from which I am drinking.
