The science of the silicon solar cell – the most important generator of solar electricity.
A simple and easy to understand animated video which explains how solar energy panels work.
This information is brought to you by Brayton Energy Canada. Brayton Energy was established in August 2008 and endeavors to advance the development of renewable and other forms of environmentally-responsible energy production.
The construction progress from February 2011 to August 2013 for BrightSource Energy’s Ivanpah Solar Electric Generating System (ISEGS) in California.
The ‘world’s largest solar-panel power plant’ is now up and running in Arizona.
“List of solar thermal power stations.”
“This is a list of solar thermal power stations. These include the 354 megawatt (MW) Solar Energy Generating Systems power installation in the USA, Solana Generating Station (USA, 280 MW) and Solaben Solar Power Station (Spain, 200 MW). The 392 MW Ivanpah Solar Power Facility, located in California’s Mojave Desert, is the world’s largest solar thermal power plant project currently in operation.”
Desalination plant in Al Jubail – Seawater to conquer the desert.
Desalinating the sea water in grand industrial scale.
Its treatment capacity is 100,000 m3 per day. The industrial city of Al Jubail MSF has two installations MSF (Multistage Flash Desalination) and three reverse osmosis plants with a combined capacity of 84,000 m3 per day. This batch of plants will supply the strong and growing demand of water that exists in the Eastern Province of Saudi Arabia.
Drinkable Sea Water
Before you scream ‘absurd’, let me tell you that I am talking about Puri – a sea water desalinating bottle. There are several ways to remove saline from sea water, for example evaporation, vapor-pressure, and ion-exchange membrane method but all of them are not practical for use on a life raft or rescue boat and require big equipments. The Puri on the other hand is a slim portable bottle that works with a pumping action. Take a look at its video below.
Introduction to desalinating
97% of the earth´s water is seawater
salt content c. 35,000 mg / liter
Domestic water supply requires:
– Dissolved solids content < 1000 mg/l - Drinking water < 500 mg/l Desalinating refers to the wide range of technical processes designed to remove salts from the water. Source: desline.com/geneva/banat.pdf
“Salt water is desalinated to produce fresh water suitable for human consumption or irrigation. One potential byproduct of desalination is salt. Desalination is used on many seagoing ships and submarines. Most of the modern interest in desalination is focused on developing cost-effective ways of providing fresh water for human use. Along with recycled wastewater, this is one of the few rainfall-independent water sources.
Due to relatively high energy consumption, the costs of desalinating sea water are generally higher than the alternatives (fresh water from rivers or groundwater, water recycling and water conservation), but alternatives are not always available.”
