New Solar Power Tree can light 5 homes in just 4 sq ft of land

New Solar Power Tree can light 5 homes in just 4 sq ft of land was originally seen on http://ift.tt/1Qfw8v0

At first, it may seem strange, but when you get used to it, the structure looks like a tree, a technological tree but nonetheless a tree. People from the Central Mechanical Engineering Research Institute (CMERI) in India have resorted to this type of design because it can yield better results with less use of space. The pictures do some of the explaining, but to make sure we will describe the solar tree. The branches hold up photovoltaic panels, each one producing five kilowatts of energy. Compared to an ordinary, ground-mounted array of solar panels, it uses only 4 square feet of land and can give 10-15% more power. Once filled, the battery can produce 2 hours of light after the source of energy is gone. You can watch the video to see for yourself this impressive solar power tree.

Homesteading is no small undertaking. The responsibility for the combination of growing your own food, providing for your own shelter and heat, and living sustainably can take its toll on even those with the stoutest of constitutions. In short, it can be difficult to get it all done.

If you are among those who resolve to achieve more in the coming year and hope to look back with satisfaction at your homesteading accomplishments, here are five ways to frame your resolutions for success.

1. Prioritize. Don’t get caught up in that which is less important. Homesteaders are frequently pulled in so many different directions at once that the tasks which get tended first are apt to be the ones that make the most noise, whether they are the most crucial or not. The squeaky wheel gets the grease, so to speak.

Be proactive about defining priorities. Make a solid decision about what aspects of homesteading are most significant to you, and proceed accordingly. If you define yourself as a market gardener who enjoys keeping a few livestock animals on the side, take care not to get so bogged down with dairy goats or breeding sows that your kale and tomatoes suffer.

2. Focus. With all the things on your plate, it is tempting to nibble at one thing and then another, without ever actually finishing any of it.

I follow a famous personal finance expert who advises people to pay off debt by tackling the lowest balance first, no matter what the interest rate. The reason this works, he says, is because success is more about motivation than math.

I have found that my money guy’s wisdom can be applied to other aspects in life, including homesteading. Sometimes it is worth it to clear an afternoon of big projects so you can tidy up some long-overdue small items. Spending 10 minutes to fix a gate latch, another 15 scrubbing out feed buckets, a few more sweeping the cobwebs from the barn windows, and a half hour pulling the weeds from around the raised bed gardens can result in the satisfaction of actually having a few things finished, and can be the shot in the arm you need to move on to other tasks. And when you get to those, focus on each one as you go, even if it means batting away the others like so many pesky mosquitoes — unless a true emergency happens, focus on the one at hand and force the rest to take a number and get in line.

3. Organize. Spend time up front arranging things — tools, food, ideas, paperwork, and so on — in a manner that allows you to locate them easily. In the end, this will save not only time but emotional energy. It is exasperating to embark upon a project only to have to hunt for the right tools and materials first, and even more so to end up having to interrupt your work and run to the store for a new thingamajigget — especially if the old one turns up later! It is also often counterproductive to begin tasks without having a clear well-thought-out plan.

Frantically searching for spare tractor keys or equipment owner’s manuals or your favorite cheese recipe, discovering some much older home-canned goods that got hidden behind the fresher jars, or making do with a too-small paintbrush because the proper sized one cannot be found are never productive ways to spend time.

4. Evaluate. Is what you are doing manageable? Homesteading is like any other occupation or lifestyle in that you need to know when to say when. Small ideas and side projects can explode into all-encompassing compulsions. A few small lambs can become an out-of-control flock of sheep. A few hours of volunteering can end up as an unpaid committee chair position that swallows you whole. Having five different species of livestock with varying housing and fencing needs can steamroll over you.

Making executive decisions is hard, but imperative. Cutbacks need to happen sometimes, even when you hate to let anything go. Remember that you, your family, and your animals will benefit from you doing fewer things but doing them better.

5. Remember. Think about the reason you got started in homesteading in the first place. Are you still headed in that general direction?

Some friends of mine amassed an expensive herd of registered miniature goats and came to the realization that too much of their time and money was tied up in buying, selling, and showing — so much so that there was inadequate room in their lives for their homesteading pursuits. They sold off the entire herd, purchased a few sturdy dairy goats, and realigned their goals.

Another reason to remember why you started is to reset your heart. In the same way that married couples can heal wounds from a fight by recalling what it was that made them fall in love with their spouse in the first place, homesteaders need to fall in love again with the ideals of homesteading every now and then. Both marriage and homesteading are too hard to do without love. Stop, roll back to the very beginning, and remember why you came.

Whether your homestead is a humble off-grid cabin in the woods with just you and a partner and a tiny vegetable patch, or a sprawling farmhouse filled with a big busy family teeming with activities both off and on the farm, you probably want next year to bring about more progress than the last. By shaping your resolutions within these five parameters, you may well set foot on the path that will lead to success in the New Year and beyond.

Portable machine turns salt water into drinking water using solar power

The following article Portable machine turns salt water into drinking water using solar power Find more on: http://ift.tt/1nr27gs

Fresh drinking water is a real problem in some parts of the world, as it is very hard to have access to it. This clever machine, designed by scientist at MIT will turn salty water into drinking water using solar energy. Oh, and it is also portable so it can be easily transported to areas in need of drinking water. The machine works through electro-dialysis and presses the stream of water between 2 electrodes that have opposite charges. The rest of it is science and it is explained very nicely at the link below that also contains a video presentation on how the entire machine works. The most important thing to keep in mind is that this portable invention is capable of filtering 2,100 gallons of water per day, which is pretty amazing.

How it works
“Electrodialysis works by passing a stream of water between two electrodes with opposite charges. Because the salt dissolved in water consists of positive and negative ions, the electrodes pull the ions out of the water, Winter says, leaving fresher water at the center of the flow. A series of membranes separate the freshwater stream from increasingly salty ones.
Both electrodialysis and reverse osmosis require the use of membranes, but those in an electrodialysis system are exposed to lower pressures and can be cleared of salt buildup simply by reversing the electrical polarity. That means the expensive membranes should last much longer and require less maintenance, Winter says. In addition, electrodialysis systems recover a much higher percentage of the water — more than 90 percent, compared with about 40 to 60 percent from reverse-osmosis systems, a big advantage in areas where water is scarce.”

David L. Chandler explains, “Electrodialysis works by passing a stream of water between two electrodes with opposite charges. Because the salt dissolved in water consists of positive and negative ions, the electrodes pull the ions out of the water, leaving fresher water at the centre of the flow. A series of membranes separate the freshwater stream from increasingly salty ones.” (news.mit.edu)

6 Simple Ways To Get More Heat From Your Wood Stove

6 Simple Ways To Get More Heat From Your Wood Stove was first published on http://ift.tt/1nr27gs

When the weather outside is frightful, it can be a challenge for people dependent on a wood-burning stove for heat. The question is: How can you improve the efficiency of your wood stove?

An obvious answer is to buy a new one with a built-in catalytic combustor, but they can be expensive. Thankfully, there are other ways to do it.

Here are some steps you can take to improve the efficiency of your wood stove:

1. A clean stove and chimney

Barring a warm spell, it’s a little late in the season to do some of this work, but good chimney sweeping and cleaning of the interior of the firebox can improve the efficiency of any wood stove. This also cleans out any creosote, which can impede air flow and pose the potential danger of a chimney fire.

Air flow is critical to good combustion and heat, and anything you can do to properly manage it will make a difference. If you have a brick chimney, make sure any cracks are sealed. This not only will avoid the potential for a fire but also will improve air flow.

2. A well-sealed stove and damper

There are two primary controls for air flow on a wood stove. These include small gaps that can be opened and closed on the front-bottom of some stoves, and the damper on top of the stove or in the chimney about two to three feet above the top. The damper is the primary air-flow control.

6 Simple Ways To Get More Heat From Your Wood StoveA problem can emerge if there are unwanted gaps on the stove. These typically happen around the door for the fire box. There are kits that allow you to replace the gasket, but it requires you to remove the door and let it cool. That’s tough stuff during winter. There are also kits that allow you easily to fill gaps as a short-term fix. Either way, an unwanted gap will cause you to lose control of your air flow and result in a fire that burns too hot for too long.

Crazy Gadget Makes Every Window A Cell Phone Solar Charger

The damper also could have a smoke leak or allow air to enter where the spindle emerges from the chimney or stove. This spindle is attached to the damper flap and here again, wood stove supply stores or websites have various solutions you can quickly apply.

Assuming your stove is well-sealed and the damper is operating properly, there are some key things to damper management. The basic advice is that whenever you start a wood stove fire, you should leave the damper fully open for 30 minutes to get the fire off to a good start and properly heat the chimney for efficient drafting.

3. Seasoned wood vs. green wood

Green wood can have a moisture content between 30 and 60 percent. The result is poor combustion and lots of smoke and creosote. In fact, green wood with a very high moisture content takes more energy to burn than the energy it releases in the form of heat. It’s important that you use seasoned wood for a wood stove.

The U.S. Forest Service recommends that firewood be seasoned for six months to a year in a sunny location and protected from rain and snow with a tarp.

Another firewood consideration: Are you using softwood or hardwood? Softwoods, like pine and fir, are great for starting a fire because they burn hot. But they also burn very fast. That’s why you want to establish a good, hot bed of glowing coals with softwoods and then add two or three hardwood logs like oak or cherry. Hardwoods burn hot when well-ignited — and burn long. Make sure you don’t overload the firebox and when necessary, carefully remove the ashes to an ash bucket and dispose of in an ash pit outside.

4. Added iron on the stove top

My mother has three pieces of cast iron in the shape of ducks sitting on top of her wood stove. The iron pieces get hot and increase the heat exchange capability of the stove by presenting a larger hot surface area to the surrounding air. There are also iron pieces with simple fan blades that actually spin very slowly as the heat rises and runs over the blades. This, to a small degree, can help distribute some of the hot air.

5. Forced-air blower

A more robust solution for air distribution is a forced-air fan that will blow the hot air from the stove’s surface into a room. This requires electricity so it’s not a pure off-the-grid solution, but solar panels could be enough to power the fan.

6. The catalytic combustor

Image source: stove-parts-unlimited.com

Many of the newer wood stoves feature a catalytic combustor as an efficiency feature. You also have the option of buying a separate catalytic combustor for installation into an older stove.

A catalytic combustor is a ceramic disc, usually about six inches in diameter and two inches thick. It has a honeycomb appearance and is coated with a rare metal called palladium. It’s inserted into the top of the stove where the smoke rises to the chimney and works to combust the smoke.

Smoke is essentially a gas that failed to combust and (most of the time) requires at least 1,000 degrees Fahrenheit to fully ignite. A catalytic combustor will combust the smoke at temperatures as low as 500 degrees Fahrenheit.

The result is that the fire burns better and hotter and any residual smoke that could cause creosote buildup is reduced. In fact, a catalytic combustor can reduce creosote buildup by anywhere from 20 to 90 percent

It’s reported that catalytic combustors are good for 12,000 operating hours before they have to be replaced. That equals 500 days, so you can probably get several years of service from one catalytic combustor.

One caution is that you should only burn natural woods (no building lumber, paper, or treated woods) with a catalytic combustor or the life of the combustor and its efficiency will decline.

Is Your New Year’s Resolution Logical?

The blog post Is Your New Year’s Resolution Logical? Read more on: http://ift.tt/1nr27gs

Wherefore our wills also have just so much power as God willed and foreknew that they should have. . .

—Augustine of Hippo, The City of God (5th century)

For we do not say that man is dragged unwillingly into sinning, but that because his will is corrupt he is held captive under the yoke of sin. . .

—John Calvin, The Bondage and Liberation of the Will (1543)

Making Changes, Making Choices

As we enter the New Year, we think about resolutions, changes, new beginnings. We think about making better choices. A new diet. More exercise. Picking up a new hobby. Sending timely reports to your boss. Finishing that book we’ve started a dozen times. Choose. Resolve. Do. It should be that easy, right?

Then why do we fail so often? And why do our resolutions accomplish so little? Why can’t we live out our choices?

Making Ourselves By Our Choices

Barack Obama wrote in his book, The Audacity of Hope, that American values “are rooted in a basic optimism about life and a faith in free will.” His claim echoes a long American religious and literary tradition that says that we have no fixed nature and that we create and define ourselves moment by moment by our choices, with our sin nature never getting in the way.

Charles Finney

Charles Finney

American roots run deep here. Before Thoreau and Emerson there was Charles Finney. Before there were public schools, there were McGuffey’s Readers. Before Netflix spies and superheroes, there was Hemingway. All have preached the American gospel of the self-made man, the man who creates himself good, on his own with never a mention of a dark or fallen side. It’s a Pelagian gospel, to be sure, and its definition of “good” has become increasingly vague with the passing decades. But not just that. Very few have even challenged the basic assumption that people can make and remake themselves by raw choice and willpower alone.

The Freedom To Choose

So, let’s examine this assumption closely. First, Scripture affirms human responsibility and the reality and significance of our choices. But it also teaches our fallen nature. Key point, often overlooked: Our choices flow from a heart corrupted by sin. In other words, fallen man is free to choose (our will is uncoerced; our actions are self-determined), but we will always choose, in some form, rebellion against God … until God changes our hearts.

The natural man finds this doctrine offensive and asserts his own freedom, his own autonomy. He doesn’t need God. But he can find no solid ground for this assertion. To see this more clearly, let’s go back to the extremes of materialism and pantheism discussed at Christmas.

Christian Heroes For Christian Kids: These Amazing Stories Are Putting God Back Into History!

The materialist reduces all to atoms. Reality is matter in motion. Everything is reduced to cause and effect. Like billiard balls scattering on the table after the break, energy particles generated in the Big Bang scatter, collide, and rebound … “off the glass” … exchanging momentum and transferring energy. Only this. Nothing else. Consciousness, volition, and choice are mere molecular interactions within the brain. After all, that’s all they can be. There is nothing else according to the consistent-thinking materialist. Appeals to quantum theory may seem to open a door to pure contingency, to pure chance, but pure chance isn’t free will. The concept of randomness isn’t consistent with the concept of a free choice. Think of it this way: Can you make a real choice if the concept of logic no longer exists?

religion-1225383_640The pantheist sees all temporal differences, all individual choices, as passing manifestations of the all-encompassing One. The individual soul is the cosmic soul and you can’t separate the two. The Hindu says “atman is Brahman.” But stop and think this through. To say “I like the Bulls but not the Cavs,” or that “Usain Bolt came in first and Bill Heid last,” or “let’s have lunch now rather than later” are all just illusions to the pantheist. Differences can’t be real if they are going to be consistent thinkers. Individual choice is irrelevant in this worldview. He who steals and he who thinks he’s been stolen from … are both confused. Not just that … even killing and dying are the same, both valid expressions of impersonal, divine reality. If “All” is one, you can’t make distinctions. If you can’t make distinctions, all choices are imaginary. Cosmic jokes.

The Gospel And Its Implications

Over against all of this, Scripture proclaims the reality of human choice and the power of God to liberate and transform the human heart.

First, the claims of Scripture are important. Scripture teaches the absolute reality of both Creator and creation. They are distinct. God exists eternally and necessarily as the Source and Ground of all created reality. (“In the beginning, God created the heavens and the earth.” Genesis 1:1.)

In God, unity and diversity are equally ultimate. God is Father, Son, and Holy Spirit. God is therefore absolute life and absolute personality. He is communion, love, and choice. This God created heaven and earth, not out of His own essence, but out of nothing. This means that the universe is wholly God’s. His deal. It exists at His pleasure and for His purposes, the terms of which are spelled out in His eternal decrees.

Second, Scripture tells us that man’s freedom is the freedom of a creature. Man can’t bend reality to his will. He can’t become a zebra or pass back and forth through time simply because he wants to. (“Can an Ethiopian change his skin or a leopard its spots? Neither can you do good who are accustomed to doing evil.” Jeremiah 13:23.)

He functions as a creature within a broader creation. And at every point, every moment, his freedom and choices are, in some way … checked, restricted, and given form by the rest of creation which itself moves at God’s sovereign command. Nobody is autonomous. Our choices are real, but not absolute. Man is, therefore, responsible for his actions and accountable to God. (Note to self: God will judge the world.)

jesusThird, Scripture tells us that our main problem isn’t that we are creatures or that we lack total autonomy … our big problem is our ethical rebellion against God. Since the historical Fall of Adam in Paradise, we’re all sinners. (“Therefore, just as sin entered the world through one man, and death through sin, and in this way death came to all people, because all sinned.” Romans 5:12.)

We are still free, within the limits of our creaturehood. And we can make choices, to be sure. But (and this is a big but) because our hearts are twisted and messed up by sin, our “gravitational pull” is toward bad choices. Granted, our bad choices aren’t always as bad as they can be … but apart from Christ “bad choices” serve the lust of the flesh, the lust of the eyes, and the pride of life. And because our hearts are “bent” this way … our nature is to not seek God, let alone serve Him.

Fourth, Scripture presents us with the Gospel: Christ Jesus came into the world to save sinners. He gave His life as an atoning sacrifice wholly propitious (paid in full) to reconcile a holy God to unholy sinners. (“Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins.” 1 John 4:10.)

He died and rose again to offer His righteousness to those who will receive Him by faith. And by His Spirit, He transforms human hearts and so grants the very faith He requires. This is called regeneration, or new birth.

The man who has been born again is free to love and serve God. He is free to make good choices, albeit ones that often fall short. Since the work of the Holy Spirit isn’t complete in this life, we will continue to struggle with our choices. But the indwelling reality of the Spirit’s presence and power make growth in grace, love, and holiness real possibilities. The one who is born of God can overcome sin, the world and the power of the devil. All this means our wills are free from the bondage of sin … allowing for prayerful change and volitional choices in Christ.

What it all comes down to is this: Unbelievers can make New Year’s resolutions. I’m not saying they can’t. What I am saying is that they just can’t make sense of their resolutions or even their day-to-day choices if they consistently play out the full implications of their worldview.

The Gospel has enormous implications for all of life.

Happy New Year!
