****Since all the comments seem to be either 100% positive or 100% negative about this solar technology i would like to clear up some some misconceptions. First of all I’d imagine that takes years to set up the the precision equipment for 2 of the largest solar panel manufacturing plants in the world and be able to print solar photo cells as fast as newspaper. After the plant was completed in 2007 the first focus was on commercial uses and their first costumers where municipal utility companies. This sounds to me like a good business tactic to help you establish a successful business from the start. Next they started offering it to electrical contractors as part of a beta testing process so they can work out the kinks that arise from scaling down their panels from large commercial ones to the ones that you can use on your house. That is where were at today. After the beta testing they will start offering them to the general public. Their website even has a place to enter your email address to be notified when this technology will be available to you the home owner. Its a process and that apparently some people out there believe happens over night. This company immediately got more financial backing then needed. Google is one of the biggest investors so I believe its all legitimate. There are two benefits from the use of alternative energy. It will save you money but also it means that energy produced is done so with out creating pollution. This is good for everybody. Even though the technology isn’t yet available for you to install on your home to help save money the fact that utility companies use it to create energy still means means less pollution for us all. . ***** New technology uses cheaper materials instead of expensive silicon crystals. These new solar cells are projected to cost 1/10th of what the more expensive silicon cells cost.

Embracing the move towards renewable energy sources, Kyosemi have revolutionized the design of the traditional solar cell, increasing it’s power generation efficiency and paving the way for innovative applications and a more economical use of raw materials. Sphelar is a spherical micro solar cell, which unlike traditional flat solar cells, can effectively harness reflected and diffused solar light as well as direct light from all directions. Each cell, is 1 to 1.5 mm and can be connected in parallel or in series, allowing for a limitless range of shapes and uses including flexible solar cells, round solar cells, or power-generating windows for buildings or offices while maintaining a certain level of transparency. Also, compared to the production process for traditional solar cells there is a dramatic reduction in the amount of wasted silicon. “In the process of producing spherical spolar cells, molten silicon is used. It’s dripped from an elevated position, and crystallizes as a sphere in mid-air, so using this process no silicon is wasted in the production of solar cells.” Kyosemi have also developed the SphelarVoice which is a battery-free wireless audio optical information system that receives information via infrared rays. The SphelarVoice uses an array of LEDs to emit a light signal which is recieved by the solar cells, converted into an electrical signal on the battery-free wireless handset and sent to the speaker.

Environmental, social and legal considerations

While most renewable energy sources do not produce pollution directly, the materials, industrial processes, and construction equipment used to create them may generate waste and pollution. Some renewable energy systems actually create environmental problems. Sustainable development and global warming groups propose a 100% Renewable Energy Source Supply, without fossil fuels and nuclear power.Scientists from the University of Kassel have suggested that Germany can power itself entirely by renewable energy.

The U.S. electric power industry now relies on large, central power stations, including coal, natural gas, nuclear, and hydropower plants that together generate more than 95% of the nations electricity. Over the next few decades uses of renewable energy could help to diversify the nations bulk power supply. Already, appropriate renewable resources (which excludes large hydropower) produce 12% of northern Californias electricity.

Although most of todays electricity comes from large, central-station power plants, new technologies offer a range of options for generating electricity nearer to where it is needed, saving on the cost of transmitting and distributing power and improving the overall efficiency and reliability of the system.

Improving energy efficiency represents the most immediate and often the most cost-effective way to reduce oil dependence, improve energy security, and reduce the health and environmental impact of the energy system. By reducing the total energy requirements of the economy, improved energy efficiency could make increased reliance on renewable energy sources more practical and affordable.

Competition with nuclear power :Nuclear power proposed as renewable energy.

Nuclear power continues to be considered as an alternative to fossil-fuel power sources (see Low carbon power generation), and in 1956, when the first peak oil paper was presented, nuclear energy was presented as the replacement for fossil fuels.However, the prospect of increased nuclear power deployment was seriously undermined in the United States as a result of the Three Mile Island, and in the rest of the world after the Chernobyl disaster. This trend is slowly reversing, and several new nuclear reactors are scheduled for construction.

Physicist Bernard Cohen proposed in 1983 that uranium dissolved in seawater is effectively inexhaustible, and could therefore be considered a renewable source of energy.However, this idea is not universally accepted, and issues such as peak uranium and uranium depletion are ongoing debates. No legislative body has yet included nuclear energy under any legal definition of “renewable energy sources” for provision of development support, and statutory and scientific definitions of renewable energies normally exclude nuclear energy.

http://www.livinggreenchannel.com Algae is the fastest growing plant life, and as an organism it converts sunlight into oil, scientists theorize that Algal biofuel can produce a whopping 30 times more energy per acre than any other biofuel option. The US Department of Energy has estimated that if Algal Biofuel replaced all conventional fuel in the country, it would require 15,000 square miles of land to harvest the algae… which is roughly one seventh of the area that is used to harvest corn in the US every year. And a diverse group of byproducts, such as neutraceuticals and feedstocks for producing plastics, can be created in algal biofuel operations, making the production more cost effective. But before we start celebrating the great biofuel solution we’ve been looking for, there are a few problems… the biomass for producing a significant amount of algal biofuel just doesn’t exist yet. The algae has to be grown from scratch and harvesting it is very expensive at this point in time. The potential of Algal Biofuel is staggering… but the problem is that, as of now, it’s all just potential. It might be years before the technology catches up to make producing algal biofuel on a large scale possible… but when that time comes, we might be able to finally celebrate a more efficient, renewable, and environmentally friendly energy source.
