Personal Solar Chargers and Wind Chargers for Gadgets !

Renewable energy chargers that are portable and not extraordinarily expensive are thankfully getting more commonplace. These make charging up your gadgets with sun and wind possible. While they don't provide energy as cheaply as plugging into the wall when you factor in their purchase price, the energy used for your gadgets is at least clean and will, eventually, be free.

It's a start---every little bit helps !!

The energy used by Canadian households more than doubled between 1990 and 2007 to power our ever-growing collections of electronics and small appliances. Look around: you probably have up to 40 plug-in devices that are drawing power even when they’re switched off. Whatever you call it — phantom power, idle current, vampire load, wall warts — the Conserve Socket Power Timer promises to save energy by cutting power to a device after 30 minutes to 6 hours.

WATER

- It is very ironic that the world is surrounded by water and only 2.5% of it is fresh water and a fraction of it is accessible.

- We may face serious water problems, if we will not use our water supply well.

- The summit endorses “More crop per crop” mentality, an approach which is about efficient irrigation technique and planting crop varieties that need less water

GO GREEN

Throwing open the windows on the first warm day of the year is one of life's great pleasures--until, of course, all that sunlight and breeze makes you realize how dusty, dirty, and cluttered your house has become during the winter hibernation. Even the messiest among us get the urge for spring cleaning--and though we don't all act on it, those of us who do should keep the annual scrub-down as green as possible

Tell me what good things have you done for our planet?

Use less plastic bottles and bags.


Use squigly lights, buy organic foods, do alot of landscaping, and last but not least recycle.


keep the forest in order to stay green.
reduce the greenhouse effect.
create a garden around the house even though small but it's a bit much to reduce carbon gases in the air.


LAST BUT NOT THE LEST RECYCLING IS  AN OPTION LEFT FOR US NOW A DAYS.

BACTERIA, SALT WATER MAKE HYDROGEN FUEL

The 'hydrogen economy' requires a lot of things, but first is an easy and cheap supply of hydrogen. There are lots of ways to make it, but most of them don't produce large quantities quickly or inexpensively.

Professor Bruce Logan, director of the Hydrogen to Energy Center at Penn State University, has found a way to change that. He used a process called reverse electrodialysis, combined with some ordinary bacteria to get hydrogen out of water by breaking up its molecules.

Water -- which is made of two atoms of hydrogen and one of oxygen -- can be broken down with electricity. (This is a pretty common high school science experiment). The problem is that you need to pump a lot of energy into the water to break the molecules apart.

Logan thought there had to be a better way. He combined two methods of making electricity -- one from microbial fuel cell research and the other from reverse electrodialysis.

In a microbial fuel cell, bacteria eat organic molecules and during digestion, release electrons.

In a reverse electrodialysis setup, a chamber is separated by a stack of membranes that allow charged particles, or ions, to move in only one direction. Filling the chamber with salt water on one side and fresher water on the other causes ions to try and move to the fresher side. That movement creates a voltage. Adding more membranes increases the voltage, but at a certain point it becomes unwieldy.

By putting the bacteria in the side of the reverse electrodialysis chamber with the fresh water, and using only 11 membranes, Logan was able to generate enough voltage to generate hydrogen. Ordinarily he would need to generate about 0.414 volts. With this system, he can get .8 volts, nearly double. (The microbial part of the cell generates 0.3 volts and the RED system creates about 0.5.)

Using seawater, some less salty wastewater with sewage or other organic matter in it and the bacteria, Logan's apparatus can produce about 1.6 cubic meters of hydrogen for every cubic meter of liquid through the system of chambers and membranes. Another bonus is that less energy goes into pumping the water -- if anything, flow rates and pressure have to be kept relatively low so as not to damage the membranes.

Making hydrogen cheaper is a necessity if hydrogen cars are to be a reality. Some car companies already make hydrogen-powered models. The state of Hawaii is already experimenting with hydrogen fuel systems. Producing cheaper, abundant hydrogen -- especially from sewer water and seawater -- is a big step in that direction.

Human Sustainability

This reflects PepsiCo’s goal of nourishing consumers with products that range from treats to healthy eats. PepsiCo’s products have always offered consumers nutrition as well as great taste. The progress that PepsiCo has made under the Human Sustainability pillar includes reformulating some of its products to improve their nutritional profile while launching products that reflect consumer demand for healthier nutritious snacks and beverages. PepsiCo partners with Governments, health officials and Non Governmental Organisations to help address obesity concerns and it continues to provide consumers with new product choices and innovations.  

Environmental Sustainability

This is based on PepsiCo’s commitment to strive to replenish the resources used where possible, and minimize the impact on the environment. PepsiCo continues to work to further reduce its water and electricity consumption and improve its packaging sustainability. Across the world, PepsiCo has re-used water from its processing plants and has worked with local communities to provide access to clean water, while supporting farmers to deliver “More crop per drop.” 

Talent Sustainability

This is founded on PepsiCo’s belief that cherishing its extraordinary group of people is crucial to building an empowered workforce. PepsiCo pursues diversity and creates an inclusive environment which encourages associates to bring their whole selves to work. PepsiCo has increased female and minority representation in the management ranks and has encouraged employees to participate in community service activities while continuing to create rewarding job opportunities for people with different abilities.   

Together, PepsiCo associates across the world are building on the platform of Human, Environment and Talent Sustainability, while delivering great financial results.
