Why should You Invest in Solar Energy?

By Tobias Lighthill


Control Your Power Bill
With solar panels installed, you have a buffer against rising power prices. Unless power companies figureouta way to charge you for the sunlight that falls on your roof, that power price is controlled by you. In effect, you can ‘fix’ the price of your solar electricity for up to 25 years.
And with rising power prices, this is becoming a very attractive option.

Increase Your House Value
Several studies have shown that solar panels add value to your house. After all, solar panels may cost as much as installing a swimming pool or upgrading your kitchen. But while not everyone may want a pool or agree with your kitchen décor, very few people mind a very small power bill.

Green Your Businesses
Having solar energy can enhance the image of most businesses. ‘Going Green’ is a major trend in today’s society. So if you own your own business, in addition to the tax rebates, solar power can give you a positive environmental image.

The Environment
There is a lot of conflicting information around this topic.Whether solar energy is the answer remains to be seen, but one thing is certain: solar energy is a lot better for the environment than coal.

Your Personalized Power Supply?

By Tobias Lighthill


Solar energy is unique in that it is generated at its place of use: ie. on your roof. This trend of personalized energy production is echoed throughout the world today.
Consider: personal computers. Personal transport (cars.) Personalized library/entertainment (internet.) Work from home businesses. Personal sound systems (ipods and mp3 players.) Personal communication networks (cellphones.)
Indeed, already solar is being plugged into portable personal systems like cellphone battery chargers and laptops.
So it’s not a large stretch of imagination to see that in a few years personal power plants could become the norm.
In effect:
Seen this way, even coal energy has the sun as its source. After all, over millions of years forests trapped the sun’s light. They were then buried and fossilized into coal over millions of years. When coal is burnt, it is simply releasing the trapped sunlight it has stored.

Solar energy is our oldest and our newest form of energy.
We are just learning how to harness it.

Solar-Powered Swimming Pool

By Tobias Lighthill


Many places around the world, such as the American Southwest, Australia, and Southern Europe, can be extremely hot and dry, and they receive significant amounts of sunlight and little rain and cloud cover.
Public and private pools are practically a necessity for the people who live in or visit these places. Swimming pools, however, consume large amounts of energy—but a pool need not be an environmental nightmare.
A solar pool pump can be used and powered by a solar array that is grid-connected or independent. In addition, the pump can be a 12, 24, or any voltage complementary to the solar array to allow for more efficient use of the electricity produced onsite.
Heating is a large expense associated with a swimming pool. Consider the enormous amount of energy that is required to heat the average 80-gallon home hot water heater. Imagine the amount of energy required to heat your 50,000-gallon pool! Heating a pool, however, can be accomplished using solar energy.
A solar pool cover resembles a large piece of bubble wrap.
The solar cover floats on top of the water and traps the solar energy in the pool—similar to how global warming heats the Earth but on a micro scale.
Here, your pool water is the Earth and the solar cover is the atmosphere holding in the heat from the sun. This type of solar cover can be deployed manually or electrically and stored in a housing transparent to the owner.

Solar water heaters can also be used to heat water in large swimming pools.

Using a solar pool heater instead of a natural gas or electric-powered
pool heater can dramatically reduce your energy use and your electric bill.

Off The Energy Grid

By Tobias Lighthill


Individuals who are committed to living without overtaxing the Earth’s natural resources have found inventive ways to exist off the energy grid. Even small communities have developed off-the-grid lifestyles through the cooperation of all the community’s residents. Rock Port (population 1,300) in the northwestern corner of Missouri converted its energy use in 2008 to a completely off-the-grid system powered by four massive wind turbines. Skeptics in Rock Port doubted the town, even one as small as theirs, could go off the grid, but their land lies on the central plains where wind blows, and blows strong.

A resident Eric Chamberlain, who led the conversion to off-the-grid living, admitted, “Did I ever think this would happen? Now, not in a million years . . . This is beyond my imagination.” In high-wind seasons, Rock Port makes more electricity than it can use, so the town puts the excess on the municipal energy grid. In low winds, the town makes up the difference by drawing electricity from the grid. Rock Port’s future may include the installation of energy storage systems so that the excess energy the turbines make can be saved for later.

Rock Port, Missouri, proves that off-the-grid living can take place in an entire municipality, although this town is small. Maybe the simplest way to move a larger and larger proportion of households and businesses from the energy grid rests in the hands of each individual.

The environmental author Alex Steffen wrote in the 2006 book Worldchanging: A User’s Guide for the 21st Century, “If houses with solar panels on their roofs and wind turbines in their backyards make you think of communes and hippies, your mental picture is out-of-date. Anyone with a bit of do-it-yourself mindset and a little disposable income can benefit from installing a home-energy system. These setups can save you real money over the long term and provide most or all of your power in clean, homegrown ways.” Put that way, there hardly seems a reason not to convert an existing building to some type of renewable energy source.

Advocates of wind power feel that establishing off-the-grid communities powered by wind may be cheaper and more feasible than installing solar energy systems. Rather than taking on the enormous job of converting large towns or cities, smaller communities of less than 10,000 people may be the best approach.

The community wind advocate Mike Bowman told E/The Environmental Magazine in 2009, “We have a distribution system in this country where 80 percent of the geography is served by rural electrics. What we have today, 70 years later, is a system that’s in place for delivering small amounts of power to thousands of places simultaneously.” In other words, U.S. energy utilities already have a good distribution infrastructure for bringing renewable energy to thousands of small communities.

Bowman pointed out the advantages of community-scale wind power stations compared with large corporate wind farms. The following suggestions could apply just as well to utilities that supply solar power, geothermal
power, or energy from biomass:
- Interconnected midsize installations can make better use of local geography than single large power plants.
- Most current transmission line grids do not have enough lines in the right places to carry electricity from solar or wind farms or geothermal sources.
- Plant managers could better control distribution and storage when the energy source fluctuates.
- Small systems can use existing power transmission lines.

Solar, wind, geothermal, and other renewable energies have established enough success stories in the United States and abroad to show that these off-the-grid methods are possible. They require only good planning, economic support—probably as tax credits—and a commitment from the community. The public has a bounty of resources at its disposal to make off-the-grid living practical. The best chance for success will likely be a strong economy that supports an innovative and growing green industry.

The Advantages Of Wind Power

By Tobias Lighthill


Although residential wind turbines and their energy source, the
wind, have a few downsides, wind energy is an abundant and renewable
resource. We won’t run out of wind for the foreseeable future,
unlike oil and natural gas.

Small-scale wind energy could also help decrease our reliance
on declining and costly supplies of oil — if electricity generated by
wind is used to power electric or plug-in electric hybrid cars and
trucks, displacing gasoline, which is refined from oil.
Wind energy can also play a meaningful role in offsetting
declining US natural gas supplies. In the United States, approximately
18 percent of all electricity is currently generated by natural
gas, according to the US Department of Energy. As supplies
decline, wind could help ease the crunch, supplying a growing percentage
of our nation’s electricity.

Wind could even eventually reduce our dependence on nuclear
power as well. In the United States, nuclear power plants generate
about 20 percent of the nation’s electricity. Although wind energy
does have its impacts, it is a relatively benign technology compared
to conventional sources of electricity. It could help all countries create
cleaner and safer energy at a fraction of the environmental cost
of conventional electrical energy production. Wind energy can help
nations reduce global warming and devastating changes in our climate.
Wind can also help homeowners and businesses do their part
in solving other costly environmental problems such as acid rain.
Another benefit of wind energy is that, unlike oil, coal and
nuclear energy, the wind is not owned by major energy companies
or controlled by foreign nations. An increasing reliance on wind
energy could therefore ease international political tension. Reducing
our reliance on Middle Eastern oil could reduce costly military
operations aimed, in part, at stabilizing a region where the largest
oil reserves reside.

Wind is also a free resource. The cost of wind is not subject to
price increases. A wind- and solar-powered future might be one
subject to less inflation. This is not to say that wind energy will be
free of price increases. While the fuel itself (the wind) is free, the
price of wind generators is likely to increase. That’s because it takes
energy to extract and process minerals to make the steel and copper
needed for wind turbines and towers. It also takes energy to
make turbines and towers and ship and install them. As the price
of conventional fuels and raw materials increases, the cost of wind
energy also will go up.

Yet another advantage of wind-generated electricity is that it
uses existing infrastructure, the electrical grid, and existing technologies.
A transition to wind energy could occur fairly seamlessly.
Thanks to generous tax credits and other financial incentives,
individuals in rural areas with good wind resources can meet all or
part of their energy needs at rates that are often competitive with
conventional sources. In remote locations, wind or wind and solar
electric hybrid systems can be cheaper than conventional power,

Maximizing the Use of Your Home Energy

By Tobias Lighthill

With the technological advancements we have today, it is hard to resist the temptation of having each electronic device available on the market. And why not grab the latest if you can afford it? However, with the increasing fuel cost and electric rate, there are things that need to be done. You may simply grab the latest plasma television or the most advanced heating system today but the thing is, you have to pay the price not only on these items but the electricity that they will consume. And chances are, if you have all the high tech stuffs at home, your electric bill does not come cheap.

So, as was mentioned earlier, something must be done in order to make sure that your are getting the most out of what you are paying each month energy. And the very first place to do some changes is right at your very home.

A typical household would spend about $1600 per year on electric consumption. You might fall under this figure. This is big enough right? But this is not the end of the story. Don’t you know that a big portion of what you are paying for electric bill is never been used? Let us put it in other words: Energy is wasted month after month right at your very home. Thus, you are spending on something that you never even use.

To make up for this, here are the changes you can do in order to get the most out of every cent you pay for your electric bill:

Turn off unnecessary devices. If you are not watching your television, never leave it on. This also goes with your stereo. Learn how to turn them off if you don’t need them. Turn off the lights if you are leaving the room as well. Also switch off the air conditioning system if you don’t plan to return for a while. If you don’t use the computer monitor, turn them off. Like the television, it consumes electricity when you are not using it.

Keep the sockets free. Unplug all your chargers. Yes, they consume small electric current but if you leave them plugged in day in and day out for months, you will feel their effects on your electric bills. Remember that these little things, when pile up can be big.

If you plan to leave the house, never let the heating system run at the temperature as if you are at home. Keep them low; better yet, turn it off. You are not using them anyway. Heating system consumes a large portion of your electric bill so you might as well do some necessary changes with them. If for instance you do not want to enter cold home, you can set up remote control heating system or a programmable heating system. In this way, you do not have to leave the heating system running all day. All you have to do is to set the time when you want your heating system to work and you will save a lot of money.

During the day, use the sun to warn up the house. The sun is free so open your drapes and windows and let your heating system rest for a while. Close the windows and drapes at night.

Instead of incandescent lights, use fluorescent. They produce more light but consume less electricity.

If you don’t want to turn the lights on and off every time you go in and out of the room, you might want to get some timers, dimmers and motion sensors to do the job for you. They are worth investing for.

Refrain from using hot water when washing your clothes. Also, it will give you much savings if you prefer washing on full loads. On your dishwasher, make sure you also full load them. If there are few clothes or dishes to wash, prefer using your hands. Air-dry them so that you do not consume more electricity.

Doing these things doesn’t mean you deprive yourself from freely using the electricity you need. It only means that you are wisely spending every cent you pay for electric bills.

By Tobias Lighthill

Dear reader,

I want to tell you, my loyal reader, about my new projects. I am thrilled to tell you more about my Facebook Page, my other website, my e-books and lots more!

1. Facebook Page: Produce Your Own Green Energy Home

I use my Facebook Page to reach more people and to stay in touch with my fans. At some point I will offer those visitors some short videos and a silly ‘Save The Planet’ game…

2. Produce Your Own Energy E-book

I’ve just finished writing my first edition of my own book! I worked all winter on it and I am quite psyched to spread the word! My book tells you what Green Power is and how you can build your own solar panels and stuff!

Upcoming projects, My New Years Resolution for 2011!

I want to develop some apps (applications) for the IPhone and Ipad. These apps will help the user to easily build a solar panel and predict their energy consumption and production. These apps will be given away freely when they are finished.

Besides these apps, I will explore the boundaries and possibilities of technology even further with a genuine free Facebook Game called ‘Save The Planet’!

May all your dreams come true!

Regards,

Tobias

Bikes Wheel Turned into Windmill

By Tobias Lighthill

It is very easy to build windmills small and affordable, with basic materials and cheap. These plants are used specifically designed for use in the Third World more than three decades. These windmills have evolved in simplicity and power. The aluminum fins are made of a curved roll flashing roller existing construction. Two 16 “sections are glued together to make a sheet. The clip wings in the rays of the bicycle wheel with a” bent nail “and a bend in the palette. Photo details will be provided shortly. The motor generator is a surplus permanent magnet and UV resistant endless belts in length is to buy from online sources.


The output is 2 amps to meet the 12 mph (18-20 volts) provides a cost effective alternative to photovoltaic panels (if the wind is available). The total cost of wind turbines less than $ 80 to buy more new items (off-the-shelf). Two of the more expensive items were the permanent magnet synchronous motor (about $ 30) Round belts and UV is generally used in food processing plants to drive carriers ($ 3 to $ 5 per foot).

The mill has a tail. The frame is made of PVC pipes. It is important to use only 24 to 27 inches at the center of the solid rear wheel bike. The wheel is mounted on a piece of PVC with a hole in the center of the nozzle.

The motor generator is a 24 volt DC permanent magnet. Surplus and is used in hard disk drives old main base. DC motors with permanent magnets are available through surplus resources of the Internet, but is rare.

The generator is mounted with a simple assembly L. Should be solid (not the typical shelf bracket) and the motor and bracket are secured with clamps to the radiator.

The turbine shaft is electrical conduit, 1.5 inch PVC blades more. A short segment of PVC pipe is screwed into the metal tube to create a bed that pivots on the turbine (PVC PVC).

The tail should be counterweighted to balance the device. Ted spent a lot of money and it was perfectly balanced. What are they good? :-)

I’m adding some new pictures. Sorry, did not act with more detailed images. This was done for some time.

Solar Power Basics

By Tobias Lighthill | 1 comment

First steps to solar
Interested in solar power, but don’t know where to start. Exploring solar (aka photovoltaic, or PV) technology can be intimidating and confusing if you don’t start with the basics.
We will begin by taking you through the process step-by-step. By the end of this article, you will have better knowledge if solar is an appropriate technology for your home, and if not, we have a few really easy and relatively inexpensive ways you can bring solar power to your home without installing a full scale solar system.
Step I:
Do you have enough sun?
This is the key question. Because if you don’t have enough sun, you can’t generate solar electricity.
We have sun almost every day of the year. But some properties are shaded by trees, so there isn’t enough sunny area, for solar panels.
For solar panels to work, the entire panel must be in the sun. If even a corner is shaded, the panel will not work.
If you don’t have enough sun, or you are renting, or there is some other reason why you think you can’t install a solar system, skip to Step 6 to find out how you CAN have solar.
Step 2:
Why do you want solar power?
If you have enough sun, the next question is, “Why do you want solar power?” The answer will determine what kind of options to consider. Solar power is still expensive, compared to the cheaper power you can get from your local utility company. Though some individual states now have incentives to lower costs, “if you live in an area where you can connect to a local utility, saving money on your electric bill is not a reason to go solar;’.
Solar does make economic sense if you are living “off-the-grid” in an area where it would either be prohibitively expensive or impossible to run power lines.
Many people, are looking into solar power because we think it is better for the environment. But is it really? “Yes!” “Some people used to say that the amount of emissions saved from using solar was less than the emissions produced by making the solar panel. But today, studies have shown that the emissions produced by manufacturing a solar panel are balanced out in three years of use. And solar panels now have warranties of 20 to 25 years, and last even longer. So there is a big environmental benefit.”
If you are interested in solar because of the environmental benefits, even generating a portion of your power with the sun will improve the environment. We have noticed that solar designers will ask, “How much power do you need;’ or “How much do you want to spend?” A solar system can be designed from either perspective.
Step 3:
How much power do you need?If you’ve made the decision to go solar because “it’s the right thing to do;’ the next thing is to figure out how much power you’ll need to produce with solar to meet the energy requirements of your household.
An easy way to do this is simply add up the kilowatt-hours (kWh) of electricity used on all your electric bills for the past year. If you don’t have your bills, your utility may have your energy usage available online, or they can tell you over the phone. Look at a whole year, don’t just multiply one month’s usage by 12, because usage fluctuates through the seasons.
If your usage turned out to be 15,000 kilowatt-hours (kWh) per year, or 15 megawatt-hours (mWh). Living in the southern states you use a lot of energy for air conditioning.
Before investing in solar technology, do everything you can to make the most efficient use of energy. Energy efficiency will save you money and help the environment, even if you don’t take the step to solar. The Alliance to Save Energy (www.ase.org) has lots of information to help you get started.
Step 4:
How much does it cost?
The cost of installing solar energy can vary widely, depending on how much energy you need, what part of the country you live in, whether you purchase your solar panels new or used, and how much of the labor you do yourself.
Each solar panel produces a certain number of kilowatts of energy. A “4 kW” system, for example, would produce 4 kW of electricity in full sunlight for one hour. To figure cost, you’ll need to know how many watts of electricity your system needs to produce.
Because the output of a solar panel varies depending on the amount of sun in your locality, the easiest way to figure out how much a solar system will produce at your house is with a calculator. There’s one online at Renewable Resource Data Center. You enter the number of kilowatts your theoretical system produces and it will tell you how much solar radiation is available throughout the year where you live and how much electricity that turns into. If you had a 4 kW system at your house it would produce 5455 kWh of electricity over the course of the year.
You would need a 10 kW system to meet 100 percent of your energy needs. Your overall cost can change depending on whether you use battery storage or tie to the electrical grid.
Step 5:
Choosing solar panels
There is more than solar panels. There is also wiring and batteries for storage, an inverter to change the DC battery power to AC current for the appliances you choose to run on AC and a battery charger (usually built in to your inverter). Installation and mounting your panels must be considered in your overall cost.
If you find solar technology bewildering, what do you do?
“The best way to choose solar equipment is to hire a professional contractor to work out a system for you. We recommend using a local contractor because solar is very place oriented. A local solar contractor can look at your site and find the exact design and products that will work best for the conditions you have. Contacting the American Solar Energy Society or the Solar Energy Industry Association to find a chapter near you. Sometimes you can get free or low cost solar panels from various sources. Building Services
Step 6:
Solar power for everyone
Despite the lack of sun on your property, you can power my home and business 100 percent with solar energy. In fact, you home or business can be recognized by the Environmental Protection Agency (EPA) as a Green Power Partner. How do you do this without solar panels? By purchasing renewable energy certificates.
Renewable energy certificates were created by the EPA to make it easy to participate in using renewable energy.
Each certificate represents the delivery of a specific amount of renewable power into a regional or national energy grid. This displaces the non-renewable fossil fuels that would have otherwise been used with energy from solar, wind, biomass and other renewable sources. The result is a benefit to the environment that is the same as it would be if you installed solar panels or wind turbines on your own home. Spending $40 a month above and beyond your regular energy bill for 100 percent solar certificates. A small price to pay for a big benefit to the Earth.
Another way to get going with solar on a minimum investment is to purchase a small solar energy kit. Real Goods offers kits ranging from $1000 to $3600 that can power lights, television, small appliances and laptop computers. These are small solar arrays that can be mounted independently on a post wherever you have sun. Wouldn’t it be neat to look down a street and see one of these in everyone’s yard?

Producing power with solar rays and super heated steam

By Tobias Lighthill

The 5 megawatt (MW) Kimberlina Solar Thermal Energy Plant in Bakersfield. The Kimberlina renewable energy solar boiler uses Compact Linear Fresnel Reflector (CLFR) technology to generate superheated steam. Each solar boiler has a group of 13 narrow, flat mirrors, that individually track and focus the sun’s heat onto overhead pipes carrying water. The water boils directly into steam. The steam can then spin a turbine to generate electricity or be used as industrial steam for food, oil and desalination processes. The Kimberlina solar boiler currently achieves 750-degree F superheated steam. The next generation solar boiler under construction is designed to achieve 900-degree F superheated steam.

The Kimberlina Solar Thermal Power Plant was the first of its kind to be built in California in more than 20 years, with the previous plant being the Solar Energy Generating Systems, which employs solar troughs.
