Researchers from MIT's School of Architecture and Planning have designed a crowd farm, that is to say a special floor that collects the energy from a walking crowd. It could be very useful in places like metro stations: A responsive sub-flooring system made up of blocks that depress slightly under the force of human steps would be installed beneath the station's main lobby. Crowdfarming is producing energy from a moving crowd and its lost energy. For more read full article on MIT site.

By 2050 livestock population is expected to double. Nowadays practices are not sustainable because they generate far too much pollution, so new practices and technologies are needed to produce better food, in bigger quantities with less impact on the environment. Cows emit methane, which is really bad in the atmosphere since it is a gas with high green house effect potential, and therefore contributes to global warming and climate changes. Some researchers report however that adding garlic to cows diet leads to a significant decrease of methane emissions (initial report says 50%). Anyway garlic is highly recommended for humans too.

Wow, i didn't expect such a detailed insight on this matter here and (most importantly) now. Thanks and congrats! This kind of approach will (i think) be more useful to all of us than most of what's generally spawned on - cars&industry. I think the more specific and more down to earth, closer to everything and anything we do we place the problem, the more likely we are to make any real change.
This is by no means ironic. Cows, for example, may seam a bit far out of the problem, but, as we all know for instance, that, with few exceptions, all water is linked throughout the planet, the same applies to the pollution issue as well, in that everything, every resource is correlated to another, and every environmental problem is just the same. Just think about it for a second: better fodder for cows- less methane; manure and other biomass (sticking to farmsites for now)- electricity and other goods such as heat, in conjunction with strategic (local) forestation to absorbe the excessive CO2 and ...

Mihaela Nechifor wrote great post about blogging. And I wanted to add a selection of blogs I read about photography. I mainly blog because I read blogs. The more blogs I read the more I blog. No wonder it is time consuming since both reading and writing take times. But there are some technologies that help a lot reading fast. For instance RSS feeds. With RSS no need to visit the web site to read what's new. Updates comes directly to your reader. I started with My yahoo and google reader, but now I use Netvibes. In my feeds about photography there is not only blogs, but ... [ Read more... ]

Yes, the RSS is an extremely handy tool. You have quite a few blogs in the feeder and they are probably time consumer, but it would probably take you forever to check them all regularly without RSS. - posted by

I am really excited to see this new tool in Dreamstime. I still don't know what we can gain from blogging on Dreamstime. I have several blogs (mostly in french), I use flickr sometimes (not recently), but what could be Dreamstime be useful to blog about? I still don t know but sure that I will figure out soon. We just need to use imagination and make something new. Blogs are better than forums for articles that take time to write and that stay for a longer period too. It is less a chat room and more a magazine. Of course I like Elen Boughn's blog and red it since quite a while. But I doubt I could write anything like that, since I lack experience and to some extend competence. However ... [ Read more... ]
