Solar Tower – renewable energy green global warming

Saturday, April 17th, 2010

EnviroMission Limited (www.enviromission.com.au) produced this 5 minute video on the pilot plant in Spain. It is an older video (2000) but gives a decent understanding of the solar tower concept.

EnviroMission, Ltd. (US Market: EVOMY, Australian Exchange: EVM) is a renewable energy developer of sustainable “green” energy solutions for the energy market. EnviroMission aims to be one of Australia’s leading producers of clean renewable energy. EnviroMission holds the proprietary rights to Solar Tower technology, a large-scale renewable energy technology based on simple fundamentals of physics — hot air rises. Solar Tower technology has the potential to offer competitive renewable energy with equal reliability to fossil fuel generators.

A single 200MW Solar Tower power station will provide enough electricity to power around 400,000 households. The energy output will represent an annual saving of more than 1,960,000 tonnes of greenhouse CO2 gases from entering the environment when compared to brown coal emissions in Victoria. The greenhouse savings equate to the removal of approximately 500,000 cars from the road. The Australian Solar Tower project consists of six distinct phases, the first two of which (project optimization and pre-feasibility commercialization) have already been completed. The third phase (final feasibility), paving the way for the implementation of the next three phases (final design, construction, and commercial operation).

Google and You! – Master Plan: HQ

Monday, February 22nd, 2010

Does Microsoft really want to be an enemy of Google?

Worldwide, Google holds a market share of 44.1%, the biggest rival Yahoo! comes on 28.7% and the Microsoft search engine MSN merely on 12.5%. Even more distinct are the numbers in Germany: With a market share just under 90% Google outclasses the international competitors.

Shortly after the founders of Google developed the PageRank algorithm in 1997, the beta-version of their search engine at Stanford University, California was quickly enjoying enormous popularity. The search engine was just better than everything known so far. The number of enthusiastic users rapidly increases. PageRank ranks websites by their relevance dependent on the incoming links.

Today, Google is one of the fastest growing companies worldwide. Within four years Google had a 70-fold increase in sales – the benefit even increases 209-fold. Google earns 99% of its sales from selling Ads. The two advertisement systems AdSense and AdWords are each gaining half of the profits.

From the beginning money was not important to the founders of Google; they wanted to make the world a better place. It’s their Vision to make any kind of information accessible to anybody. In this point of the movie we have the first scepticism towards Google: the whole information will be controlled by Google.

Today, Google offers its search function in more than 100 Languages. In addition they offer a constantly growing list of currently over 80 free features. Using these services users reveal more and more private information, parts of which are then accessible over the Google search engine.

In the beginning Larry Page and Sergey Brin assembled their Computers themselves from individual parts. So they always had the ideal hardware for the self-written software. Even today the so called Googleware is tailored specific to Googles requirements. Due to this perfect blend of hardware and software Google has an enormous computing power with minimal expenses.

Google turnover speak an own language: Google is the biggest existing provider for online service. But long since, Google has also reached the offline market. In North America, Google already provides advertising to magazines, newspapers and radio stations.

Google is cooperating with the leading molecular scientist Dr. Craig Venter, who profoundly participated in decoding the human genome. Google is able to contribute enormous computing powers as well as the required data storage for this work – more, than the government could ever provide. Dr. Craig Venter claims that Google could soon start a service anybody would be able to check its own hereditary faults or diseases. This way, Google even gets an insight in its users genes.

Which Solar Panels Work Well For Residential Use?

Tuesday, December 29th, 2009

http://www.solardave.com/index.php/which-solar-panels-does-indepedent-power-systems-like-video/

SolarDave: What manufacturer do you like to use for solar panels and why?

Tony Boniface: We prefer SunPower because for a couple of reasons, one is their efficiency – they are the most efficient panel, also they are all black with also lends for a nice aesthetic attribute. Black seems to blend in to the houses the best, we found they kind of disappear.

Those are the two main reason, but SunPower has made a big effort to counter where the industry has been fits and starts they force dealers to traditionally forced to inventory panels, SunPower is all about just-in-time delivery. So it makes a difference from a cash flow point. For a small business that can be critical.

They are (SunPower) are very interested in growing their market share and they realize the one way to do that is to make our market share grow – they understand and cater to the small business both from an inventory stand point and a marketing materials stand point and sales department and training. So they do a really good job of assisting there dealers where ever possible.

SolarDave: What other panels do you like to use?

Tony Boniface: By request of on occasion if we can’t get what we need from SunPower we for a particular project we may fall to EverGreen or Kyocera for instance – both good makers, EverGreen has the advantage of they are an American company.

Kyocera in my opinion has been in the industry the longest and has stayed the course. They are also a materials company they make ceramics glasses and so forth so I think the quality is very high.

SolarDave: What SunPower models do you like to use the best?

Tony Boniface: SunPower likes to minimize the number of models they had. If they could have come out with just one they would have. They try to avoid scope creep as the more models they have they more people you have to keep tabs on.

They have two models a high efficiency the white module with the white backing and they have the slightly less effiencent model which is the all black (loss a little efficiency) right now it is the 230 watt the white one and the 225 watt is the black. That SunPower 225 watt has changed though because the process has become more efficient in the cells – it used to be the SunPower model 205 and 210 then 215 220 and now it is the 225 and 230. So it is pretty typical in the industry as the manufacturers are getting the efficiencies up.
