ISEF: The Laudry's Done...Now Let's Make Bread!

This is the forth in our series of projects from ISEF that we will be covering. Many more to come. Thanks to Intel for flying me out and take cialis putting me up so I could cover the conference.

Washing machines are versatile instruments, and they’ve been used in many applications which have nothing to do with getting your whites white. I’ve seen them converted into Sten guns in WWII and their timers connected to IEDs in Iraq, but 3 students from Cuiaba, Brazil, have come up with a use for it that actually helps people. Because of levitra discounts the rampant hunger in their country, Cleiton Silva Soares, Pitter Wesley dos Santos Oliveira and Gleberson Sena Souza, decided there needed to be a practical solution to tramadol cod only feed low-income families, and it had to make economic sense. They settled on having the wow look it express viagra delivery families produce bread at home, saving money versus buying it in the store, but as anyone who’s made bread from hand knows, it’s a LOT of work.

So they decided to make dough mixers, and to make them out of materials that were cheap and abundant: old washing machine parts. They pulled some parts together; the motor, the agitator, the drum, etc., and built an easily serviceable mixer that could be repaired in the field for little or no cost by just about anyone. Under their trial tests the mixer was given to families to produce bread for the community nursery. The results are that the mixer helped reduce the average monthly cost of bread per family from $30.45 to $14.70 (US dollars). For a family living on very little income, that 52% difference is quite a big one. Unless Brazil runs out of old washing machine parts, which is unlikely, these launderers / bread makers will be populating rural communities very soon.


Brazillians turn Batteries into Pigments!

This is the first in our series of projects from ISEF that we will be covering. Many more to come. Thanks to Intel for flying me out and putting me up so I could cover the conference.

As ecogeeks, we tend to have a number of gadgets around, many of them powered by batteries. When we throw them away, they either go to indian cialis landfill, where their toxic chemicals pollute the soil and water, or we recycle them, reusing their components.

That’s what 3 Brazilian students are doing, but in a very unique way. Camila da Silva Bruzadelli, Alan Juliano de Andrade and Deborah Asbahr, of Limeira, Brazil, have discovered a way to make pigmentation that can be used in ceramics coloring, from batteries. In their state of Sao Paolo, 192 million batteries are used each year, with only a fraction of them being recycled. But what batteries they do receive, they disassemble into their constituent components, being cardboard, plastic, steel and graphite, each of can you buy ultram over the counter which can be recycled using the buy cialis canada existing infrastructure.

The zinc, manganese, and iron, can be combined with the electrolyte, which is treated with nitric acid, filtered, neutralized, and then heated at 1000C for 4 hours to obtain the various metallic oxides. These are then applied to ceramics, which are also baked and glazed. The oxides provide several colors; from a light rose to a dark brown. They plan on discount online levitra approaching the ceramics industry with this technology and the best choice 100mg levitra hopefully end up reducing both the amount of artificial pigmentation created or mined from minerals, and the amount of batteries that do not make it to the recycling depots.


Apparently Keyboards Hate Mice

I don't generally get excited about people making art out of trash...but that's because it's not generally this awesome. My one question is...why do the mice seem to be running toward the snake? I guess that's for the artist Choi Jung Hyun to buy viagra now explain.

Recycle Bank Raises $13M (and Recycling Rates to 90%)

What if there were a reason to recycle? Wouldn't it be cool if you were, in some way, reimbursed for all that sticky fingered, paper cutting work that you do every Wednesday evening?

I mean, after all, you are performing a service. Basically, you're a miner. Mining your trash for aluminum, PET plastic, silica and cellulose. So why not get wages like miners do? Some people have been asking those questions...and that's why RecycleBank was formed.

But that's not why RecycleBank just got $13M in venture capital funding. They got that money because their system actually works.

RecycleBank puts an RFID chip in all of their recycling bins. The chip is linked to individual's names and accounts. The recycling trucks then weight your recycling (if properly sorted) and give you credits based on the amount of stuff you're recycling. The credits can then be exchanged like airline miles. Except, instead of flights, you get a buck off your latte at Starbucks, or cheaper dog food, or a free rental at Blockbuster.

Of course, there are a few problems with this idea. First, it kinda encourages people to consume more. I don't have much recycling because I drink water and read the newspaper online. If I got incentives for my cans, I might start drinking Mountain Dew again. Another possible issue is canadian pharmacy tramadol theft. As weird as it sounds, neighbors might start swapping bins under the cover of darkness, or even plundering recycleables.

But so far, in pilot projects, that doesn't seem to have been a problem. Two Philidelphia communities saw recycling rates increase from 7% and 35% to 90% each!

I haven't heard of a 90% recycling rate anywhere outside of Europe, so those are very exciting numbers. Especially because more people recycling means more raw material per man-hour and vehicle-mile, which signficantly increases the probability that recycling authroties will actually make money.

Recycling by Mail: Free, Fast and Easy

Imagine a world where trash is so valuable that, instead of throwing it away, the post man comes and picks it up from your doorstep and whisks it off to some exotic location to be re-used, re-purposed or recycled.

Well, that day may actually be here. Except, instead of any old's only small electronic gadgets and printer cartridges.

The U.S. Postal Service recently decided that they were going to indian cialis generic house a new kind of pharmacy order tramadol recycling center. They've teamed up with CORE Recycling Concepts (part of Clover Technologies.) by placing free mailers in over 1,500 post offices. The Postal Service is asking people to put their electronic "trash" into the mailers. The post office then pays shipping to Clover's sorting centers. Once there, the items are sorted, and then either sold to companies that can use them, or recycled.

The project is centered on a few large cities right now. But if Clover can make enough money, and pay the wow look it online levitra prescription Post Office back for it's trouble, they could expand the program nationally in the fall.  Here's hoping!

Check out the full press release after the jump.
