Top 10 Emerging Environmental Technologies



Just because you're concerned about climate change doesn't mean you have to live in a yurt in outer Mongolia. You can be passionate about the Environment, without strapping yourself to a whaling ship or using yourself as a human shield against bulldozers that mow down old-growth trees. All it takes are a few smart, fuss-free choices to make the change you wish to see in the world, while rejuvenating your body, home, and planet at the same time. Choosing green might even save you some green in the process. This list of ten is by no means exhaustive, but it's a righteous start.




One Bright Idea


If you're going to do just one thing for the planet, make it the switch to compact fluorescent light bulbs (CFLs). Although they cost several times more upfront than regular incandescent light bulbs, they also last about 10 times longer, which means that for every CFL you screw in, you'll be saving eight incandescent light bulbs from landfill purgatory. Plus, you'll save some serious cash in the long run. Because CFLs use 75 percent less energy, swapping one incandescent bulb for a CFL reduces carbon dioxide by 500 pounds a year; replacing 17 has the equivalent effect of taking one car off the road for a year. Just remember to recycle spent bulbs responsibly - CFLs contain trace amounts of mercury, which although isn't enough to be hazardous to you, could pose a problem in landfills when mercury from multiple bulbs leaches into the ground.

Seeing Stars
The average home can pump out twice as much greenhouse-gas emissions as the average car. Purchasing energy-saving Energy Star-rated appliances, electronics, and lighting can help mitigate that, while slashing a third of your electric bill. (A power guzzler is nobody's friend.) Improving the energy efficiency of your home could even earn you tax credits from Uncle Sam.

Paper nor Plastic
Eschew plastic bags by bringing your own reusable canvas totes the next time you're at the supermarket or store. Because petroleum-based plastic isn't biodegradable, it's certain to outlive you-by about a millennium or so. Each year, thousands of marine animals, including the endangered leatherback turtle, choke to death on plastic trash they mistake for snackable morsels. Our unholy love for plastic disposables has also bred a swirling vortex of plastic trash the size of Texas in the North Pacific Ocean-not surprising when you consider that Americans run through about 100 billion plastic bags annually, using up an estimated 12 million barrels of oil.

No Soliciting
Deforestation is responsible for 25 percent of all carbon emissions released into the atmosphere, through the burning and cutting of 34 million acres of trees annually. Save some virgin and old-growth forests by opting out of paper catalogs and browsing online, instead. Why did you think Al Gore invented the Internet? Shed those extra 41 pounds of junk mail the average American packs on each year by removing yourself from direct-mail mailing lists; if you need a tad more help, companies such as GreenDimes and 41pounds.org have got your back.

Get Better Mileage
Who knew cauliflower were such globe-trotters? Or that jet-setting tomatoes racked up frequent-flier miles? But it's true: North American produce typically travels a minimum of 1,500 miles. Grapes can clock 2,143 miles cruising from vineyards in Napa Valley to supermarket aisles in Chicago, gobbling up barrels of crude oil and spewing pollutants and greenhouse-gas emissions in their wake. By buying your produce locally, whether it's through the farmers' market or a community-assisted agriculture program, you can reduce your "food miles," otherwise known as the distance your food has to travel to get from the farm to your plate. Now that's fresh.

The 3 R's

Start rolling those Rs: Reduce, reuse, and recycle-and in that order. Let's face it, we're mired deep in ecological debt because we're consuming more resources than nature can replenish. By gorging on more than our fair share of the world's resources, we're also diverting essentials such as food, clothing, and water from communities in greater need. So let's recap: It's better to reduce your personal consumption than it is to reuse something, and it's less environmentally taxing to reuse a product than to have it recycled. Separating recyclables from your regular trash, which barely takes any effort, is a no-brainer, of course; recycling aluminum, for instance, takes as little as 5 percent of the energy we'd need to manufacture virgin aluminum.

Get Off the Grid
Opt for clean, renewable energy if it's offered in your area. Low-impact sources such as wind, solar, and hydroelectric power reduce our dependence on coal-burning power plants, a major source of greenhouse-gas emissions. And because harnessing the power of renewable "fuels" such as sun and wind are free, your electric bill is likely to scale down because of the reduced price of wholesale electricity.

Slay Energy Vampires
You may not know it, but households across the globe are infested with vampires. Energy vampires, that is. Cleverly disguised as innocuous household appliances (psst undead that consume 1,000 kilowatt hours a year per household, while in standby mode: your toaster, coffeemaker, hair dryer, PC, printer, cable box, and cell phone , your television is one of them), their nasty pointed teeth plunge deep into your wall socket, draining power all hours of the day and night, even after you've switched them off. (Americans pay $1 billion a year to power our televisions and VCRs while they're turned off.) Other sleeper agents of the electriccharger. You don't have to live in a constant state of fear, however, forever checking behind your back for that one appliance you forgot to pull the plug of. Just plug adjacent equipment into power strips with surge protectors, and before you crawl under the safety of your covers-or head out to work-simply flip the switch.

Go Natural
Our chemical arsenal may be able to exterminate creepy crawlies and polish our countertops, but they're slowly killing us, too. The man-made chemicals we favor are like the obnoxious houseguest who overstays his welcome-an average of 200 industrial compounds, pollutants and other chemicals, for instance, were recently discovered in the umbilical-cord blood of newborns. (These included seven dangerous pesticides, some of which were banned in the U.S. more than 30 years ago.) We're serving our kids potent chemical cocktails even before they're born-not quite the head start they may have been hoping to get. Pesticides have also been implicated in Parkinson's disease, infertility, brain damage, and cancer. So ditch the poisons and choose natural, non-toxic, and equally effective methods of cleaning and corralling pests. You probably already have what you need in your kitchen to get started. Chowing down on organically grown food will cut out pesticides from your diet, as well.

Build it Green
Trees, in a word, rock. They absorb heat-trapping carbon dioxide, hold soil together to prevent landslides, and provide a rich habitat for diverse plants and animals. Choose furniture made from eco-friendly sources such as sustainably managed forests, bamboo, and reclaimed wood. Buying vintage wherever possible, rather than adding something new into the waste stream, is always in style. Also, look for furniture that is durable and likely long-lived-you'll save money on replacements in the future and prevent more wasted materials from winding up in the landfill. And, if for some reason, that dresser or dining table no longer suits your needs, something in fine shape will always have takers via Craig's List, eBay, or Freecycle.

Did Torrents change the face of modern day downloads??


The only solution to this question would be "yes!!!" . Yes, the whole new evolution of Torrents has revolutionized the Downloads and made easy for the users to share files. Gone are the days when u used to wait for longer hours so that a server would allocate required bandwidth for us to download , the wait for the response etc etc was quite a bit painful job. But since the torrents use peer-to-peer responses it has become easier .... Let us first know more about torrentz..



What is Bit-Torrent
BitTorrent is a peer-to-peer file sharing (P2P) communications protocol. BitTorrent is a method of distributing large amounts of data widely without the original distributor incurring the entire costs of hardware, hosting, and bandwidth resources. Instead, when data is distributed using the BitTorrent protocol, each recipient supplies pieces of the data to newer recipients, reducing the cost and burden on any given individual source, providing redundancy against system problems, and reducing dependence on the original distributor.
The protocol is the brainchild of programmer Bram Cohen, who designed it in April 2001 and released a first implementation on 2 July 2001. It is now maintained by Cohen's company BitTorrent, Inc.
Usage of the protocol accounts for significant traffic on the Internet, but the precise amount has proven difficult to measure.
There are numerous compatible BitTorrent clients, written in a variety of programming languages, and running on a variety of computing platforms.
How does it operate??
A BitTorrent client is any program that implements the BitTorrent protocol. Each client is capable of preparing, requesting, and transmitting any type of computer file over a network, using the protocol. A peer is any computer running an instance of a client.
To share a file or group of files, a peer first creates a small file called a "torrent" (e.g. MyFile.torrent). This file contains metadata about the files to be shared and about the tracker, the computer that coordinates the file distribution. Peers that want to download the file first obtain a torrent file for it, and connect to the specified tracker, which tells them from which other peers to download the pieces of the file.
Though both ultimately transfer files over a network, a BitTorrent download differs from a classic full-file HTTP request in several fundamental ways:
  • BitTorrent makes many small data requests over different TCP sockets, while web-browsers typically make a single HTTP GET request over a single TCP socket.
  • BitTorrent downloads in a random or in a "rarest-first" approach that ensures high availability, while HTTP downloads in a sequential manner.
Taken together, these differences allow BitTorrent to achieve much lower cost, much higher redundancy, and much greater resistance to abuse or to "flash crowds" than a regular HTTP server. However, this protection comes at a cost: downloads can take time to rise to full speed because it may take time for enough peer connections to be established, and it takes time for a node to receive sufficient data to become an effective uploader. As such, a typical BitTorrent download will gradually rise to very high speeds, and then slowly fall back down toward the end of the download. This contrasts with an HTTP server that, while more vulnerable to overload and abuse, rises to full speed very quickly and maintains this speed throughout.
In general, BitTorrent's non-contiguous download methods have prevented it from supporting "progressive downloads" or "streaming playback". But comments made by Bram Cohen in January 2007 suggest that streaming torrent downloads will soon be commonplace and ad supported streaming appears to be the result of those comments.
Downloading Torrents n sharing files
Users browse the web to find a torrent of interest, download it, and open it with a BitTorrent client. The client connects to the tracker(s) specified in the torrent file, from which it receives a list of peers currently transferring pieces of the file(s) specified in the torrent. The client connects to those peers to obtain the various pieces. Such a group of peers connected to each other to share a torrent is called a swarm. If the swarm contains only the initial seeder, the client connects directly to it and begins to request pieces. As peers enter the swarm, they begin to trade pieces with one another, instead of downloading directly from the seeder.
Clients incorporate mechanisms to optimize their download and upload rates; for example they download pieces in a random order to increase the opportunity to exchange data, which is only possible if two peers have different pieces of the file.
The effectiveness of this data exchange depends largely on the policies that clients use to determine to whom to send data. Clients may prefer to send data to peers that send data back to them (a tit for tat scheme), which encourages fair trading. But strict policies often result in suboptimal situations; e.g., when newly joined peers are unable to receive any data because they don't have any pieces yet to trade themselves or when two peers with a good connection between them do not exchange data simply because neither of them wants to take the initiative. To counter these effects, the official BitTorrent client program uses a mechanism called “optimistic unchoking,” where the client reserves a portion of its available bandwidth for sending pieces to random peers (not necessarily known-good partners, so called preferred peers), in hopes of discovering even better partners and to ensure that newcomers get a chance to join the swarm.

So what are shared through torrents??

Well.. infact every file can be shared over the torrents. Music,Films,Dvds,Applications,Software,Documents,Games,Pictures, etc , u name it they have it!!
