Greenhouse Gas Could Drop With Diet Change for Cows, Sheep

You ride your bike to work every day, you eat locally grown food, you recycle, and turn off all of the lights when you leave the room. So, what else can you do to help the environment? Start feeding your cows better, for one. According to a new study by DEFRA ( Department for Environment, Food, and Rural Affairs) in the UK, changing the diet of livestock like cows and sheep could help reduce the level of greenhouse gas emissions.


The department recommends a diet of “maize silage, naked oats, and higher sugar grasses,” according to Reuters. Feeding cows high sugar grasses could reduce methane emissions by 20 percent, and feeding sheep naked oats could reduce sheep’s emissions by 33 percent. 

Of course, there are other concerns to factor in, as well. Says DEFRA, “In the longer term the benefits gained by changing animals’ diets will need to be considered against other environmental impacts as well as how practical or costly they are for the farming industry to implement.”

Ford Using Tiny Bubbles To Reduce Vehicle Weight

One of the fastest and most efficient ways to make a care more environmentally friendly is simply to make it lighter. Less weight means less fuel is needed to power the car. And Ford has developed a way to potentially lighten its fleet by around 10 percent.

The secret is bubbles. Tiny bubbles. A technology developed by MuCell actually injects plastic materials with carbon or nitrogen bubbles, which significantly reduces vehicle weight without compromising the strength of the materials. Though it’s still in the trial phase, Ford is hoping that the bubble tech will allow the company to reduce the weight of its cars by anywhere from 250 to 750 lbs by 2020.

New England Farmers Will Soon Be Harvesting Energy

Digester dome.jpeg

Farmers produce all sorts of goods in order to earn money, and soon they may be able to add renewable energy to that list.

A new machine called the digester — which look like a giant silo — is able to take waste such as manure and discarded crop material and turn it into energy. The digester turns the waste into biogas, which is then fed into a nearby generator to produce electricity. This electricity is then fed back into the grid, earning the farmer a tidy profit. Up to $20,000 a month, in fact.

And not only does the digester provide additional revenue and a renewable source of energy, it also utilizes materials that would otherwise go to waste. The project is being funded by New Englad Organics, who expect it to cost around $2.5 million before all is said and done. And it sounds like farmers in the region are excited about it.

“Milk and power are both livelihoods for us,” farm owner Randy Jordan told CNet. “I want to do it all and I’ll just keep cows as a hobby.”

Solar Powered Wind Turbines Are Twice As Green

For researchers at the University of Liverpool, wind turbines weren’t enough. They need to be solar powered wind turbines.

The design aims to fix one of the main issues with wind turbines: that they’re essentially useless when there’s no wind at all. By having photovoltaic solar cells included on the spinning blades as well, the turbines will also be able to generate power via the sun, thus making them more useful.

One unintended problem, though, based on computer simulations is that the moving solar cells produce bright beams of light. These could potentially be temporarily blinding for people nearby, which could be especially dangerous for pilots.

Currently the team is looking for a place to start testing the turbines, preferably outside of England where wind and sunlight aren’t available in large amounts. “We are confident we can transform the world’s renewable energy needs,” Dr. Joe King told Inhabitat. “Just think what our turbines could do in countries like Australia.”

Scientists Creating Plastic From Chicken Feathers

In an effort to be more efficient and use every part of the animal, scientists have discovered a way to create plastic from chicken feathers.

Developed by researchers at the University of Nebraska, the plastic consists of approximately 50 percent chicken feathers, significantly reducing the amount of petroleum needed. The plastic itself is also very light and, because it’s derived from mainly natural materials, it’s more degradable than traditional plastics as well.

“[Prior] technology uses keratin [a chemical found in feathers] as an ‘additive’ to polyethylene and polypropylene,” Professor Yiqi Yang told the BBC. “Our work turns feathers into something like polyethylene and polypropylene.”

While the feather-based plastic is certainly more environmentally friendly than petroleum-based plastics, further research and testing is required to determine whether or not it will be feasible at a larger scale.

Gorgeous Bench Made From Discarded Metro Cards

Anyone who has be on the New York City subway in the past several years knows that the underground transit system is perpetually littered with discarded Metrocards. Sometimes the things can be refilled, but many of the longterm cards are rendered useless the moment their time is up, and those disposal boxes that only exist as a place to get rid of the cards are seemingly perpetually overflowing.

New York artist Steve Shaheen opted to turn waste into art, soliciting people on Craigslist to help him collect disposed cards. In the end, they collected 5,000 Metrocards in less than a week. “There is something very personal about handling so many small belongings that were once riding around in peoples’ pockets,” Shaheen said of the cards. “There are untold personal stories in that inconspicuous, flimsy plastic.” 
The cards were placed over a steel frame to construct a flowing bench, which has since gone on to be displayed at NYC’s Sloan Fine Art museum.

Zero Emissions Cabs Gear Up For London Olympics In 2012

The iconic London cab is getting a touch of green, as the first fuel cell-powered cabs have hits the streets of the British capital.

One of the zero-emissions cabs made a trip around the city last week, but the plan is to have an entire fleet of the cars servicing London by next year, which just happens to be the year when London will be hosting the Olympic Games. How many cars will be in the fleet wasn’t announced.

The cars themselves are powered by a fuel cell/battery hybrid system that gives them a range of 250 miles, and also allows for “rapid refuelling,” which would be a necessity for a car that’s on the road virtually all day long.

Canadian Farmers Manage Fertilizer Use With iPhone App

40 farmers from the tiny Canadian province of Prince Edward Island are utilizing new software to help manage their fertilizer use. And they’re doing it from an iPhone.

The new app, called PEI AgriLogic, as developed by a software company in Quebec in conjunction with PEI’s department of agriculture. It keeps track of how much fertilizer a farmer uses, which in turn helps determine how much nitrogen is being put into the ground. The farmer simply records voice messages throughout the day, and the app transcribes them for easy record keeping.

“The very last thing we want to do is work a long day and come home and have to enter a pile of notes into something,” one farmer told the CBC.

The province hopes to double the size of the pilot program next year, before hopefully making it available province wide.

CleverWraps Is An Incredibly Wasteful iPad Cover

There are plenty of options when it comes to keeping your iPad clean and safe, and amongst those it’s not hard to find something that’s environmentally friendly. But the disposable CleverWraps might just be the most wasteful amongst the bunch.

The idea behind CleverWraps — which also come in mobile phone and eReader varieties — is that you can use it as a temporary solution for those times when your gadget is at its most vulnerable. At the beach, for example, or while cooking.

it’s an interesting idea, but since the wraps are disposable it also means that it’s incredibly wasteful. $15 will buy you a pack of three, but since they’re made for single-use, this makes CleverWraps not only wasteful but also overly expensive. For a little bit more you could purchase a reusable, green case that won’t end up in the garbage.

IE9 Is The Most Energy Efficient Browser, Says Microsoft

Instrumented laptops.jpeg

Chances are you stopped using Internet Explorer a long time a game, with Chrome, Firefox, and Safari being much more appealing alternatives. But if you’re looking to reduce your energy consumption while on the computer, you may just want to give IE another look.

According to Microsoft, the latest iteration of the browser, IE9, consumes less energy than the competition. This was discovered via several real-world tests, which included measuring power consumption while reading a news site and while using HTML5 applications. IE9 performed lowest in each of the tests, with Firefox coming in a close second.

Of course, since the results are coming directly from Microsoft they should be taken with a grain of salt. All of the tests were run in Windows 7, so Mac users don’t really get a clear picture of their browser energy use. But either way, it’s an important factor to consider when choosing a browser. Not only does less power consumption mean you’ll be losing less energy, but for laptops and other portable devices it will help save battery life.
