Years of research have perfected using solar devices to pasteurize water, and the results have been very successful. Many scientists have developed ways to render the power of the sun to destroy viruses, diseases, parasites, and bacteria found in water, mostly using solar cookers or solar ovens. This newfound procedure for pasteurizing water could be the solution for people in developing countries lacking access to clean, drinkable water. Many lives will be saved if all people have access to clean water, and the spread of waterborne diseases will decrease greatly. The use of solar cookers and ovens just might be the technology that helps achieve this goal.
One of the most respectable scientists in the field of solar water pasteurization, and one of the original founders of Solar Cookers International, Dr. Robert Metcalf has…
P110/120: Energy/Energy & Technology Fall 2015
1. Solar energy can be attractive not only environmentally, but also economically. If an electric clothes dryer has a power rating of 6000 W and is used for 1 hour per day, how much money can be saved in a month by using the "backyard solar clothes dryer" (see Fig. 6.37 in your text), assuming electricity costs 10 cents per kWh?
6000 W x 1hr/day x 30days/month x 1kW/1000 W x $0.10/kWh= $18.00/ month
So $18 a month for electric…

With using this you know when you need to use the battery it’ll work and also you can reuse it and just charge it back up to use the battery again. This battery is also a green battery so you’re not using your electricity from your home to power this battery. So with the information above shows that maybe green energy saving batteries may be better than using wind and solar energy.
Pros and Cons
Pros of the energy saving battery. This green battery can help us in many ways than you may think.…
The Search For Life on Other Planets/Moons
For years and years scientists have had mars in their crosshairs when discussing life on other planets within our solar system. Now say we discover that mars is completely lifeless in every way possible. Is there any other possibility of life in our solar system? The answer to that question is in the moons of Jupiter.
More specifically the moon europa. There is no absolute proof because scientists have not had the opportunity to land anything…
questions in astronomy today is the how our solar system formed? Not only does the answer adds an insight to other similarly forming systems, but also satisfies our curiosity about the origin of our species. It is extremely unlikely that astronomers will ever know with absolute scientific clarity how our system originated, they can however construct similar theoretical models with faiths of gaining a better understanding. With that being said a simple understanding of the current physical…
There are a few arguments made in the article Irrational Dreams Of Space Colonization makes a point by saying “The solar system could also potentially be exposed to galactic sources of high energy gamma ray bursts that could fry all life on Earth; any moon or Mars base would face a similar fate” (Williams,…
We had a big convention in France with other countries about pollution and what we could do to cut back in causing smog and other terrible pollution things. Because all we are doing is shortening our lives on earth, and pollution has been proven to cut back years on your life expectancy, because China has caused so much pollution they lost 1-2 years in life expectancy. Personally I don’t think this is going to do anything so we should look towards our own country and do what 's best for us.…
Energy plays an important part in social and economic develop. As the oil price sharply increases, it stimulates the step of researching the renewable energy field. The advantages of using renewable energy reduce the dependence on fossil fuel resources and carbon emission to the atmosphere. The total incoming solar radiation is about 3.8 million EJ per year and it can satisfy the entire energy demand if utilise correctly . The use of solar energy is usually identified in two contexts: passive…
Solar photovoltaic technology has made vast improvements over the past thirty years. Solar panels now are able to stand up to expectations of producing energy. A study was done in 2005 showing that solar energy provided over 13,000 MW. In turn this would generate 23.7 million MWh annually in Virginia which is about 21% of current electricity consumption. Residents can add solar panels to their roofs, and be put on existing buildings also one can make a solar farm. So by the year 2025 Virginia…
