Does Rain Making Really Work?

Written by Graham McClung

Whenever there's a drought, someone will come up with repparttar idea of finding a rain maker, or holding a day of prayer for rain.

Now far be it for me to make light of people who are in truly desperate straits and who are prepared to try anything to relieve their precarious situation. The worst that can happen, assuming no deliberate or unknowing fraud, is that everyone has something else to think about for a day or so. For a while they have some cause for hope.

And it may indeed rain andrepparttar 150140 drought will be over. But in most cases not.

Rain making can be divided into two types - cloud seeding, which has strong scientific and engineering reasoning behind it, and, forrepparttar 150141 moment, everything else.

Cloud seeding has been used to create or increase rain for over 50 years, and whilerepparttar 150142 results are a little patchy and rarely spectacular, whenrepparttar 150143 right combination of cloud seeding method and clouds is present, it has been shown to work many times over, and in a cost effective way.

But what ofrepparttar 150144 rest? I don't wish to questionrepparttar 150145 power of prayer, which presumably transcends all physical rules, but it is worth looking at just what it would take to changerepparttar 150146 weather pattern before it is ready to change.

But first let's take a look atrepparttar 150147 rain maker's methods.

They can be divided into two parts - local knowledge and rainmaking techniques of ceremonies.

Firstly, rainmakers with a good reputation will generally be folk with a strong knowledge of local weather, climate, and seasonal changes. Some of these may be subconscious, but I think we can give them some credit for astuteness and good observational powers. This allowsrepparttar 150148 rainmaker to practise his or her rituals at a time when a change inrepparttar 150149 weather seems most likely. With good local weather knowledge, chances of success will be high, and in any event, payment is usually dependent on success. It is also human nature to remember (and advertise)repparttar 150150 successes and forgetrepparttar 150151 failures.

Advantages and Disadvantages of SOLAR ENERGY

Written by Anita van Wyk

Many of us know that solar energy is good, but few really understand why.

Therefore, I compiled a comprehensive list of solar energy advantages and disadvantages that will enable you to make an educated decision whether on not Solar Power is right for YOU. Solar Energy Advantages

1. Saves you money

  • Afterrepparttar initial investment has been recovered,repparttar 150139 energy fromrepparttar 150140 sun is practically FREE.
  • The recovery/ payback period for this investment can be very short depending on how much electricity your household uses.
  • Financial incentives are available formrepparttar 150141 government that will reduce your cost.
  • If your system produce more energy than you use, your utility company can buy it from you, building up a credit on your account! This is called net metering.
  • It will save you money on your electricity bill if you have one at all.
  • Solar energy does not require any fuel.
  • It's not affected byrepparttar 150142 supply and demand of fuel and is therefore not subjected torepparttar 150143 ever-increasing price of gasoline.
  • The savings are immediate and for many years to come.
  • The use of solar energy indirectly reduces health costs.

2. Environmentally friendly

  • Solar Energy is clean, renewable (unlike gas, oil and coal) and sustainable, helping to protect our environment.
  • It does not pollute our air by releasing carbon dioxide, nitrogen oxide, sulphur dioxide or mercury intorepparttar 150144 atmosphere like many traditional forms of electrical generations does.
  • Therefore Solar Energy does not contribute to global warming, acid rain or smog.
  • It actively contributes torepparttar 150145 decrease of harmful green house gas emissions.
  • It's generated where it is needed.
  • By not using any fuel, Solar Energy does not contribute torepparttar 150146 cost and problems ofrepparttar 150147 recovery and transportation of fuel orrepparttar 150148 storage of radioactive waste.

3. Independent/ semi-independent

  • Solar Energy can be utilized to offset utility-supplied energy consumption. It does not only reduce your electricity bill, but will also continue to supply your home/ business with electricity inrepparttar 150149 event of a power outage.
  • A Solar Energy system can operate entirely independent, not requiring a connection to a power or gas grid at all. Systems can therefore be installed in remote locations (like holiday log cabins), making it more practical and cost-effective thanrepparttar 150150 supply of utility electricity to a new site.
  • The use of Solar Energy reduces our dependence on foreign and/or centralized sources of energy, influenced by natural disasters or international events and so contributes to a sustainable future.
  • Solar Energy supports local job and wealth creation, fuelling local economies.
