Rendering fecal waste safe for reuse via a cost-effective solar concentrator
The goal of this work was to design a cost-effective solar-thermal waste treatment unit and evaluate its ability to render fecal waste safe for reuse. Three trials were conducted from December 2011 through February 2012 in FAVET-Universidad de Chile, Santiago, Chile. The first two trials evaluated helminth viability daily. To calculate the inactivation rate for the solar concentrator unit, ...

Solar power plants mw or kw?
Solar power has come as a blessing to the humanity, not only to provide energy to all but to save humanity from the evils of industrial revolution. The biggest evil of industrial revolution in last two centuries is the concentration and centralization of wealth and resources and also huge political powers in the handful of people. So huge factories, mass production, big industrial and financial ...

Large parabolic solar baskets
I have recently designed and started manufacturing large parabolic solar baskets which will be proved to be the most revolutionary tool to produce local power in farms, in industries and in villages and to decentralize world economy from oil based to soil based. My solar baskets are one type of parabolic solar concentrators with short focal length which will be produced at the cheapest rates even ...

Energizing our green future
As world leaders come together at the UN General Assembly to adopt new sustainable development goals, climate change activists gear up for Climate Week in New York City and the Pope brings his message to the United Nations, a shared vision of our future is coming into clear focus. If we are to eradicate poverty, we need to tackle climate change. And since 2008, the $8.1 billion Climate ...

Designing renewable contracts that value CSP storage
As California ramps up its storage requirements, it has not included Concentrated Solar Power (CSP) with integrated energy storage. Instead it is testing pilot projects using batteries at utility-scale, even though it must be obvious to bean counters at utilities that batteries are never going to compete with utility scale CSP storage. By Susan Kraemer The 32 MWh battery storage pilot for ...

Renewable Power Generation Costs in 2014
Executive Summary The competiveness of renewable power generation technologies continued improving in 2013 and 2014. The cost-competitiveness of renewable power generation technologies has reached historic levels. Biomass for power, hydropower, geothermal and onshore wind can all now provide electricity competitively compared to fossil fuel-fired power generation (Figure ES 1). Most ...

Techno economic performances of a dry cooling solar power tower plant under Algerian climate
The Sahara represents more than 80% of the total area of Algeria. This region is characterised by the high level of solar energy potential. On the other hand, concentrating solar power plants represent 70% of the total power to be installed in the framework of the national plan of renewable energy and energy efficiency which consists of installing up 22,000 MW of power generating capacity from ...

South African concentrated solar power executives call for more competition amongst EPCs
In an exclusive CSP Today study of over 100 executives in the concentrated solar power industry in South Africa it has emerged that more competition between EPC contractors was viewed as the number one factor in reducing costs in CSP development. The results emerged as part of the CSP Today ‘CSP in South Africa: Industry Development Survey’, where over 100 executives were surveyed ...

Can the Solar Hourglass serve as a CSP landmark?
A CSP project proposal has won first place in the 2014 Land Art Generator Initiative (LAGI) competition, but can the design make it beyond paper? By Heba Hashem October was an eventful month for Santiago Muros Cortés. The Argentina-based architect impressed the jury in Copenhagen with his plan for a Solar Hourglass that would use a solar beam instead of sand as a trickling material. The ...

CSP faces new California siting limits in DRECP
The publication of the Preferred Alternative draft of the much-awaited Desert Renewable Energy and Conservation Plan (DRECP) brings both hope and consternation to supporters of clean energy in California. DRECP would close approximately 20 million acres of a 22 million acre area of California desert lands to large-scale renewable energy development, while still allowing renewable development on ...

Some surprising facts about Ivanpah
Ivanpah, the world’s largest power tower CSP project, seems to attract a lot of controversy. Along with that, it brings up concerns about its operations. CSP Today has received some interesting questions amounting to ‘Has something gone wrong? Is Ivanpah not really working?’ By Susan Kraemer In such novel technology built at such scale, it is perhaps not surprising that there ...

Near Term Lower Cost Solar Electric Power for US Commercial Customers
Market Opportunities The first market for PV electric power panels was for space satellites. While the single crystal cells used in these panels made these panels very expensive, this was unimportant for that market. That market emphasized reliability, not cost. As these panels came down to earth for off-grid remote applications, again the emphasis was on reliability and low maintenance, not ...

Demonstration of a 33% efficient Cassegrainian Solar Module
Abstract The Cassegrainian solar concentrator module concept we shall describe here uses a primary and a dichroic secondary mirror to split the solar spectrum into two parts and direct the infrared and near visible portions of the spectrum to two separate cell locations. An efficiency of 32.9% (STC) is reported measured outdoors for a solar concentrator PV module using InGaP/GaAs dual junction ...

How Does Solar Energy Transformed into Electricity?
Many years ago, solar energy was never been the subject of all talks. Basically because the solar energy was never given that importance in people’s day to day life before. They just ignore and did not give attention on its importance. They fail to realize the importance of it. Now, as the period of modernized society where new technologies and innovations occurred came, the demand for ...
