Could this be the beginning of more green space programs? Next month, Japan is launching a spacecraft propelled by solar sails in deep space. The Ikaros, as the ship has been christened, will take to the skies on May 18, 2010. Ikaros means “Kite-accelerated interplanetary spacecraft by radiation from the sun.” The name is also a reference to the Greek myth of Icarus, a young man, with his father Daedalus, attempted to escape Crete by exile in the configuration of the wings of feathers and wax.

According to myth, Icarus flew too near the sun and heat melted the wax of his wings, making it to plummet to death. We certainly hope the spacecraft Ikarus meet a happier fate when the rocket takes off from the Tanegashima Space Center. Its creators call a yacht Ikaros space. ” 46 foot candles are thinner than human hair, but that will drive the ship, taking the pressure of light particles from the sun colliding with candles. The Ikarus is also equipped with solar panels to generate electricity.

“Solar sails are a technology that realizes space travel without fuel, we have sunlight,” said Agency of Japan Aerospace Exploration Agency (JAXA) spokesman Yuichi Tsuda. “The availability of electricity would enable us to sail further and more effectively in the solar system.” Solar sails have been tested in vacuum chambers by NASA in the past, but the agency failed to deploy this technology successfully.

If successful, the Ikarus will be the first spacecraft to use solar sails in space as a primary method of propulsion. This has cost JAXA spacecraft ¥ 1,500,000,000 (about $ 16 million) to build. The rocket also carried into space the first satellite launch in Japan of Venus. Plans for the future of JAXA could also include sending a robot to the moon by 2015 and the creation of a personal robot moon base by 2020 at a cost of 200 billion yen ($ 2,000,000,000) from here 2020.

By way of comparison, the Apollo project cost was $ 25,400,000,000, as reported in 1973 (that’s about 175 billion U.S. dollars now), and President George HW Bush’s era, the proposed NASA mission 400 billion dollars to Mars in 1989. the future of NASA lunar mission costs is projected at 104 billion U.S. dollars over 13 years in 2005. Other missions proposed low-cost lunar costs have been estimated at about $ 10 billion. Congratulations to JAXA to create an alternative economic resources and relatively easy to conventional methods of space exploration. We look forward to hearing more about the mission

On April 22, 1970, became the first demonstration for land, in order to create awareness activities to help conservation of natural resources.

One such initiative is the reference to the use of solar energy to heat water that is usually used for showers.

However, systems that have been industrially produced and marketed, at least in Guatemala, have such high costs for residential use, which is cheaper, still use traditional systems based on electricity or gas, to move a water heating system with solar energy.

Taking the case of Earth Day, I share these videos, which have been produced by Green Power Science initiative, which explain how to build a home water heater, solar energy.

I have researched on the physical principles being applied and I’ve also found that in Guatemala, I can find all the necessary materials. Before the season begins in winter, when the region I live, I hope to have built a system similar to the video.

If anyone is interested too, can find more information on Green Power Science and unloading the work plan. Apart from the electricity savings and economic inputs, it seems an interesting way to live in a greener world.

Technology Review, a publication of MIT, has just its annual list of the 10 new technologies that will change the world published one day. The list includes everything from phone screens in 3-D television social electronic medical implants. Three green innovations, including two solar energy applications, has it in the 2010 TR10 list. Each technology is that a researcher or a group to push certain area is connected. I think the future these green energy will replace the  traditional electronics like laptop battery, cell and so on.

Here are three I found most interesting:

Solar fuels

can can convert Joule Biotechnologies Noubar Afeyan genetically microorganisms, sunlight into ethanol or diesel, that one day make biofuels competitive with conventional diesel, gasoline or natural gas.

The light-trapping PV

Kylie Catchpole, National University of Australia, the efficiency of thin-film solar cells by depositing silver nanoparticles on the surface of the cell. This seems to raise more traps photons and the efficiency of the laptop battery cell. An innovation that contribute to the fact that solar power could be competitive with fossil fuels.

Green Concrete

The third innovation is an eco-concrete. At a time when cement production accounts for 5% of global carbon emissions, Nikolaos Vlasopoulos Novac has a cement that actually developed a carbon “sink” that absorbs and stores carbon for Sony PCGA-BP2EA. Ultimately, it could reduce and offset global carbon emissions from cement production.

What I find interesting on that painting the TR power of all innovations in the development of solar energy at the moment, solar solar space, chose solar fuels and the capture of light-PV as the most willing to change the world, as it now can replace the Sony VGP-BPS2C to power the laptop.

It is easy to understand how solar energy would fuel the list. What would be an incredible breakthrough, if free and abundant solar energy, could literally, to create clean fuel for our cars. An interesting note is the choice of Joule Biotechnologies own instead of Daniel Nocera MIT, whose company manufacture Sony VGP-BPS5A, Sun Catalytix has also developed a solar fuels. Nocera course includes a vision of a hydrogen fuel cell-class solar energy to GM Afeyan, photosynthetic microorganisms contrary.

The inclusion of a layer of silver catches the light in the thin-film solar cell is a little confusing. Just because I am on the quantity and the ease with which the efficiency of the cell increases confused. To be honest, I should push efficiency innovations all the time, many of which actually maybe what they say, but they are still in development … Kylie Catchpole of the ANU. So what makes this Silver Lining “promising than other research projects in the eyes of the TR?

Catchpole and staff of the ANU have been investigated, as the metal nanoparticles can increase the absorption of thin-film solar cells. Plata, apparently is the best in “dispersion” of light (and not from) a thin layer of silicon and a steady power supply for Sony VGP-BPS9. Because I have not read Catchpole research publications on the subject, I can not be sure how much more efficient, the study has its solar cell test – apparently enough to impress people by the magazine Technology Review made.

Finally, we have a concrete – a truly valuable innovation, if negotiable, the building uses as more and more efficient, new materials Sony VGP-BPS5 such as concrete with high thermal inertia. In order to really create a particular product that a carbon sink and not as a manufacturer of gas, so that undoubtedly changed the world.

Solar Energy in Ontario was almost as much electricity as all U.S. nuclear reactors, Studies Find

The studies, led by engineering professor at Queen Joshua Pearce, is the potential of solar energy first in the region to explore. Professor Pearce was how many would be produced gigawatts by surprise.

“We came in large numbers, and were conservative. There are about 95 gigawatts of potential only in southeastern Ontario – which indicates a huge potential,” says Professor Pearce, who specializes in solar photovoltaic and Sustainability Applied Materials, now I can power my Inspiron 6400 battery out of the door.

A study accepted for publication in the journal Computer discovered, environment and urban systems, that in choosing the roofs in southern Ontario were covered with solar cells, which could be five percent over five gigawatts of all products Ontario energy. The study took into account the roof orientation and shading.

“To put this in perspective, produce all the coal power plants across Ontario a little over six gigawatts. The sun does not always appear, so if solar power will couple with other renewable energy sources such as wind, hydro and biomass, southeastern Ontario could easily meet their energy needs, while solar power is not free, stable electron volts my Dell Inspiron 6400 battery, “says Professor Pearce.

A second study, published in the May issue of the journal Solar Energy looked, country in southeastern Ontario, which could be used for solar farms. The study considered the country with little economic value – barren, rocky and not suitable for building sites in the vicinity of the electricity system, laptop battery – and concluded that it has the potential to produce 90 gigawatts.

“Nuclear energy for all in the United States is approximately 100 gigawatts. We can only produce 90 to barren land with solar energy in this small space, so we’re not talking about little else,” says Professor Pearce.

The teacher conducted the research on decision-makers with solid numbers on solar energy potential and possible locations for the developer of solar parks in the future, we can image the solar panel can replace laptop battery charger in Africa.

A new contribution to the studies were civilians Reina student in mechanical engineering and engineering student Lindsay Wiginton Ha Nguyen.

Batteries are all over the place, we can see it in all kinds of electronic devices. A laptop battery is an electrochemical device to convert chemical energy to electrical energy to provide power to our electronic devices. The chemical used in battery will pollute the environment heavily if the batteries are improperly disposed of. In this article will show you how to safety disposed and recycled a used battery.

Environmental Hazards of Household Batteries

There are more and more batteries using in our household. A laptop battery is an electrochemical device to convert chemical energy to electrical energy to provide power to our electronic devices. Batteries contain heavy metals such as mercury, lead, cadmium, and nickel, which can heavily pollute the environment when batteries are improperly disposed of.

Batteries may produce the following environmental hazards:

Burning the Dell inspiron 6400 batteries in public area will pollute the lakes and streams as the metals vaporize into the air when burned and it may cause burns or danger to eyes and skin.

Contribute to heavy metals that potentially may leach from solid waste landfills.

Batteries waste in riverside will pollute the water with strong acid. Animals or human drinking from these water will be harm by the pollution of the water.

What you can do before buying new batteries

So, do you wonder what you can do before buying the new Inspiron 1520 battery to prevent waste and lower the environmental impact of your hand. Here will provide some of the recommendation for you.

Buy batteries that have less mercury and heavy metals. The batteries now are reformulated to reduce the usage of mercury. Some batteries such as the alkaline inspiron 1525 battery have had about a 97 percent mercury reduction in the product. Newer alkaline batteries may contain about one-tenth the amount of mercury previously contained in the typical alkaline battery. Some alkaline batteries have zero-added mercury, and several mercury-free, heavy-duty, carbon-zinc batteries are on the market.

Try to not buy more batteries when you already have enough battery on hand. Most of the people likes to buy more batteries and store it at home but it will not be using in some time. This is a waste and will increase the risk of battery pollution in your house.

Consider using of rechargeable batteries. Rechargeable batteries as inspiron 1300 battery, has longer life span and use fewer batteries. However rechargeable batteries still contain heavy metals such as nickel-cadmium. When disposing of rechargeable batteries, recycle if possible.
