DIY Soap!

handmade and homemade soap

There are few things in the world of DIY home goods that carry as much of a unique coolness factor as bath and body products. For some reason, it never occurs to people that they can actually make their own versions of these products. It’s as though people think that these things need to be made in some huge factory, using crazy machines that no one even knows the name of. I don’t know if this says worse stuff about us or the products we slather all over ourselves, but either way, it doesn’t need to be this way. There are a few really great soap recipes out there that just about anyone can easily complete.

The one I’m putting on here is a cucumber soap recipe, and it’s great. This one is super simple and very easy to make. Not only does it use some more common items than other soap recipes, but it carries with it a certain natural cache. After all, cucumbers are used around the world for their astringent properties, so you’ll be making soap with a kick. The recipe is pretty simple:

1 & 1/2 c. cleanly rendered tallow
1 c. cucumber pulp
1/2 c. vegetable oil
3/4 c. cold soft water
1/4 c. lye flake3s
1/2 tsp. wheat germ oil or vitamin E oil

Grate every part of the cucumber to the finest texture that you can possibly get it. I mean EVERY part of the cucumber. Nothing goes to waste. Bring the tallow to a melt, and stir in the cucumber until you get a good mixture going. Keep it on the lowest heat your stove can manage for about half an hour, stirring infrequently.

Add the vegetable oil to the tallow, and set it aside. Add the lye flakes to the cold water, and set that aside as well. Once the two are cooled to about equal temperatures, you’re going to start stirring the lye into the tallow. It’s very important that you stir the lye into the tallow. Lye is an extremely caustic substance that can produce severe chemical burns. If you pour the tallow into the lye, you run a greater risk of having lye splash up onto your skin, so pour the lye into the tallow gently. Stir them together, and let the mixture sit.

Grease your molds with the petroleum jelly, and add the rest of the ingredients (wheat germ, vitamin E) to the lye/tallow mixture while stirring very slowly. Once they’re mixed and relatively lukewarm, pour the mixture into the molds and let it sit.

Lo and behold… soap!

An Eco Friendly Hummer?

green hummer

When one thinks of an eco-friendly car, the humvee isn’t the type of vehicle that normally comes to mind. Nor is a car that would be spotted on the streets of Great Britain, however, last weekend a Humvee was indeed spotted roaming the streets of the city. The car wasn’t turning heads for the normal, obvious reasons, it was catching people’s attention because of its significantly reduced size and because it is electric. This new design is called the MEV HUMMER HX.

The MEV HUMMER HX is the only proportionally correct licensed resort vehicle currently on the market. Its design matches the infamous Humvee and includes the characteristic louver grille, custom wheels, door sills, styled seats, and floor mats.

MEV, or My Electric Vehicle, was formed in 2006; initially trading as Mini Hummer Europe and achieved year on year growth because of its introduction of luxury golf cars manufactured by others to the European market. As a result of poor growth and lack of sales from third party suppliers, a decision was made in 2009 for the company to design and develop their own products.

The greatest thing about this new Hummer is that it is not a gas guzzler like its predecessors. This Hummer is electric and can be charged from a 12V charging point. Despite the fact that General Motors closed the Hummer automotive plant in 2010, it is believed that the little HX model could have saved the brand.

Just before closing the factory, MEV managed to sign the worldwide exclusive rights to manufacture the HUMMER HX as a mini electric vehicle.

Natural Gas Cars

fuel pumps

Given the recent uprising against Hosni Mubarak’s three-decade dictatorship in Egypt, Americans should note how political and social conditions in the Middle East can rapidly and unpredictably change.

So, does it make sense for the world’s largest economy to be heavily dependent for oil in a region where disruption is always a possibility? No, it doesn’t. Yet America has been reliant on the Middle East for oil for most of the automobile age. Only recently has there been any effort to switch to alternative fuels and lower America’s dependence on imported oil.

Even though the U.S. has increased domestic drilling, they wouldn’t be able to pump its daily consumption of 18.7 million barrels per day without the imported fuel to make up the difference. In November 2010 alone, the country imported an average of 8.25 million barrels per day. Nearly 2 million of these came from the Middle Eastern oil producers, according to the U.S. Energy Information Administration data.

What then is the solution to becoming less dependent on foreign oil? Many believe that the answer could be in domestic natural gas.

HOMEGROWN FUEL

The only domestic energy source that has the potential to end the country’s dependence on oil for transportation fuel in the U.S. is natural gas. Natural gas is abundant, competitively priced, clean, and available domestically.

Of all of its good qualities, abundance is the most appealing advantage. The Potential Gas Committee (PGC) has estimated that the U.S. had 1,836 trillion cubic feet (Tcf) of recoverable natural gas as of 2008, out of a total future natural gas resource base of 2,074 Tcf. This would meet the nation’s natural gas demand for about 100 years, based on the nation’s current consumption rate.

Of the 22.8 Tcf of natural gas consumed in the U.S. in 2009, 90% was produced domestically. Furthermore, most imports of dry natural gas came from a reliable trading partner: Canada.

Natural gas has become a highly used energy source for industrial, commercial, and residential uses. However, it has yet to play a larger role in transportation fuel, aside from use in bus fleets and other industrial fleets.

WHY SIZE MATTERS

Two factors make the use of natural gas unappealing to consumers. The first is its lack of compactness. Large vehicles, such as buses and vans, are able to accommodate the large tanks that natural gas requires. However, smaller cars and modest-size SUVs cannot accommodate the large tanks without displacing volume from features that car buyers find appealing: trunk and cargo space.

The second issue stems from the lack of natural-gas filling stations. Even with more stations being added each month, there are only around 1,100 stations throughout the entire U.S. Compare this number to the more than 160,000 gasoline stations and it is obvious why it is more convenient and appealing to have vehicles which use gasoline.

To combat these two issues, public policy would have to heavily encourage natural gas fuel use in order to increase its role as a transportation fuel. U.S. drivers will not be likely to leave behind their gasoline habits, even if gasoline becomes more on a per-mile basis than natural gas.

PRICING

Critics of natural-gas point out that the current price of natural gas would likely go up if drivers shifted in large numbers to natural gas. Of the nearly 12 million natural-gas vehicles in use globally, only 110,000 are found in the U.S.

A counterargument to the critics’ point is to simply ask: What is going to happen to the price of gasoline in the upcoming years? The International Energy Agency predicts that global oil demand will rise in 2011-2012 due to economic expansions worldwide. This prediction could be wrong and the demand could always drop.

Currently, the price of oil is about $91 per barrel. However, given the rising demand in emerging-market economies for oil, how likely is it for the price of oil to stay the same? As global demand accelerates, it has been predicted that oil may top $100 per barrel in 2011.

FOREIGN OIL DEPENDENCY

As history has shown, events in the Middle East are subject to periods of interruption. Whether or not the price of gasoline remains stable or declines, it will not eliminate the liability of U.S. oil consumption.

Clearly oil will remain an essential fuel in the upcoming years; however, the U.S. needs to see that the energy future will be reliant not only on the price but also on the reliability of the energy sources.  Natural gas could provide the U.S. with the necessary solution to the uncertain international energy dependence.

Biofuel from Cows

illustration of cow

Scientists have turned to the digestive tract of cows to study how to break down plant matter and convert it into energy. By using genetic materials from a cow’s rumen, the U.S. Department of Agriculture (USDA) has begun developing new ways to break down plant fibers for conversion into biofuel.

To convert switchgrass and corn stover, the leaves and stalks of maize, into biofuel requires the plant fibers to be broken down into sugars. The difficulty comes when cell wall polymers are cross-linked in various ways that make them resistant to breaking down. This finding comes from Dominic Wong, a chemist at the USDA Agricultural Research Service (ARS) Western Regional Research Center, located in Albany, California.

Through previous studies, it was discovered that a unique group of enzymes knows as feruloyl esterases (FAEs) are able to break down key links between the polymers. Studies have also shown that the enzymes are produced by specific types of microbes that degrade plant materials.  Wong collected the microbial population from a cow’s rumen and screened their genetic composition to find which genes produced FAE enzymes.

Wong has worked with scientists at Cargill to isolate, sequence, and clone 12 genes which are capable of being introduced into Escherichia coli for production of the enzymes. These enzymes then can be used to break down the polymeric network in the plant cell wall. Wong and the team of scientists at Cargill have written up a provisional patent application on the FAE genes and enzymes.

Furthermore, the enzymes can also be used to enhance the digestibility and nutritional qualities of animal feed, help with the development of nutritional supplements, and be of use in the development of other value-added products.

Agave: A New Bioenergy Crop

Agave, known for its use in the production of alcoholic beverages and fibers, grows chiefly in Mexico and the south-west of the United States, as well as tropical South America. Agave grows best in semi-arid regions where it will not likely come into conflict with food and feed production. Agave is a succulent with the ability to survive long periods of time without water. An article written in an issue of Global Change Biology-Bioenergy states that there is Agave may potentially be used as a sustainable biofuel feedstock.

In 14 independent studies, scientists have found that Agave yields greatly exceed the yields of other biofuel feedstocks, such as corn, soybean, sorghum, and wheat. Furthermore, scientists have noted that there are various other species of Agave in existences that have not yet been evaluated.

Sarah Davis, a bioenergy analyst, states, “We need bioenergy crops that have a low risk of unintended land-use change. Biomass from Agave can be harvested as a co-product of tequila production without additional land demands. Also, abandoned Agave plantations in Mexico and Africa that previously supported the natural fiber market could be reclaimed as bioenergy cropland. More research on Agave species is warranted to determine the tolerance ranges of the highest yielding varieties that would be most viable for bioenergy production in semi-arid regions of the world.”

The economical and environmental sustainability of Agave could greatly stimulate the economies in Africa, Australia, and Mexico, where large amounts of land are unused due to the arid climate.

Solar Panel Tents

illustration of the sun

The US Army has developed portable tents that have flexible solar panels built into them. The solar cells are based on thin-film amorphous silicon, giving them durability and flexibility. Three models have currently been created and are known as the Power Shade, The TEMPER Fly, and the QUADrant. Each solar tent has a different energy generating capacity depending on the size of the tent and thus the actual number of solar panels that have been installed. “The Power Shade can generate about 3KW of electricity (the largest quantity of the three), the TEMPER Fly outputs about 800W, and the QUADrant generates around 200W of power.” This energy is used to power the high tech communication devices that have become standard for the military. The ability to gain energy from renewable and sustainable sources should greatly decrease their dependence on fuel as well as make the units far more portable.

Nowhere are solar panels more efficient than in the middle of the desert. The cloudless skies and long days will enable the solar panels to generate electricity to the best of their potential. I cannot really think of anyone else that would want to have tents like these. Most campers aren’t going to travel with enough electronic equipment to make such a system necessary, but I certainly cannot speak for everyone.

Ring Socket Timer

earth with recycling symbol

Energy conservation should be on the minds of everyone who has an electrical bill to pay. Vampire energy is the electrical power consumed by electronic devices while they are turned off and unused. Most people fail to appreciate how much power is simply wasted in modern homes. By taking the time to turn of surge protectors when you are not using your computer or entertainment system can have a significant effect on the energy consumption of your home and help to make your lifestyle more environmentally friendly.

Shown here is the Ring Socket, featured on Yanko Design’s website. The Ring Socket is a fairly simple idea that builds a timer into an electrical outlet. This functionality forces the user to determine how long they plan on using their electronic device and thus consider home much electricity they are going to consume. Most importantly, the socket isn’t an energy-saving device that relies on the user to turn it off. Even if you forget, the Ring Socket shuts off once the time has expired. The light-up ring would also have an indicator built-in, as shown below. If put into use, I really doubt anyone would ever pay to have a Ring Socket installed on every outlet in their home, but the design addresses an important point in the push for energy efficiency and conservation. People get distracted and even the most energy-conscious person can let their habits slip. The Ring Socket eliminates even the potential to waste power by automatically cutting off electrical devices when the time has run out.

Portable Solar-Powered Insect Killer

solar powered insect killer

Created by Gotcha, the Solar Powered Insect Killer is a simple and portable little device that would be perfect for any outdoor activities. Sitting around outside when the mosquitoes are out is perhaps one of the most uncomfortable things imaginable. Plus, since there is no need for batteries or to keep the device plugged in, you can take it anywhere. As long as it has been left in the direct sunlight for several hours, the fully charged unit will continue to operate for about 5 hours. That means up to 5 hours of enjoying the night, comfortable and insect-free.

This Solar Powered Insect Killer works by attracting the insects and bugs to the extra bright LEDs. And just like the classic insect killer, the bugs are drawn closer and closer to the light until they are zapped by the high voltage grid that surrounds it. All the power for the LED light and the high voltage grid is created by the two mounted solar panels and stored in a rechargeable battery. For even more convenience, the unit switches from solar powered to running off the battery automatically when the sun goes down, so you don’t even need to think about it. The special LED light attracts mosquitos, midges, and biting flies into a high voltage grid. The pests are killed instantly. The built-in handle and included stand make the Solar Powered Insect Killer an easy and portable device that will greatly improve people’s enjoyment of the outdoors.

The Scoop on Sulfates in Shampoo

empty shampoo bottles

You may already buy healthy shampoo. By healthy I mean shampoo that does not contain harmful chemicals, parabens, or sulfates, and that is not tested on animals. No matter what the product claims, look closely at the ingredients because it may, for example, not contain parabens, but it still could contain other chemicals and the company may test on animals.

You may have heard that shampoo that is “sulfate-free” can be great for color-treated hair and for individuals with an allergy or sensitivity to sulfates. This is very true and it is also ideal for anyone looking to eliminate unhealthy ingredients from their daily cleansing routine…

Many of the hand soaps, shower gels, bath bubbles, and facial cleansers on the market today are made with “surfactants” rather than natural soaps. Sulfactants is a group of chemicals known as “sulfates”, along with the bad-for-you trio of related chemicals diethanolamine (DEA), monoethanolamine (MEA), and triethanolamine (TEA).
Similar to soap, surfactants make washing with water more effective by suspending dirt and oil in the water to wash off of you more easily. They also help create that thick foamy lather Mr.Bubble showed some of us when we were kids. That does not mean that they are good for you. The most common sulfates are sodium lauryl sulfate (SLES) which is a milder, chemically altered version of SLS. Keep an eye out for this ingredient in shampoo and liquid soaps so you can avoid it if possible. In addition, avoid other sulfates such as sodium myreth sulfate and ammonium laureth sulfate. These ingredients may cause soapy lather but they can cause dry skin, scalp irritation, and hair loss! Even worse, the process of converting SLS into SLES can contaminate the shampoo with dioxane, a human carcinogen. Read labels — just because a shampoo says “SLS-free” does not mean that it is sulfate-free.
Sulfates can cause irritated skin because the sulfates are incredibly harsh. They can also cause a depleted layer of oil on skin and hair which makes the skin prone to dryness and environmental damage. In addition, surfactants can react with other ingredients in the formula to create other carcinogenic compounds.
It can be an adjustment to switch to less foamy, not-so-bubbly shampoos and liquid soaps. Remember that suds are not what cleans away dirt and oil. Try switching to low sudsing formulas that are free of sulfates, DEA, TEA, and MEA. Look for cleansers that contain gentler ingredients instead, like Cocamidopropyl betaine, sorbitan laurate, sorbitan palmitate, and sorbitan stearate. Your skin and body will thank you.

Wal-Mart Goes Green

walmart store front

Guest Post By Jim Fitzgerald

Watching baseball’s first quadruple-play was strange. Seeing Wal-Mart go green
is stranger still.

First the baseball: The scene was a game of T-Ball, where everyone bats every
inning, regardless of the number of outs.

The bases were loaded when a line drive ended up in the glove of the pitcher.
While he wondered how it got there, all the runners took off without tagging
up. The pitcher ran to third, then second, then first.

We kept counting the number of outs and they did not add up. First in our heads:
That doesn’t make sense. Then on our hand: That’s crazy. Then our other hand:
It kept adding up to four outs.

It took us a while to believe what we saw right in front of us.

And now Wal-Mart, the original Black Hat, is going green. Or better said, sustainable.
Let that sink in because it is true. Big time.

So much so that Treehugger.com says It “could end up being one of the biggest
motivators to make truly ‘green’ products ever.”

As in the history of the world.

Wal-Mart has made believers out of not just the biggest environmental organizations
in the world — like the Environmental Defense Fund and the World Wildlife Federation
– but also Wal-Mart’s suppliers.

It started five years ago when Wal-Mart announced three goals: 1) 100 percent
renewable energy; 2) Zero waste; 3) Sustainable products.

Wal-Mart stores have already gone sustainable on dozens of fronts from shipping
to selling to storing to recycling. Last year, Wal-Mart saved 4.8 billion plastic
shopping bags.

That’s how they roll in Bentonville: Big.

Even the combined efforts of 8400 stores with two million associates doing $400
billion in sales every year was not enough: Wal-Mart figured out 90 percent of
the carbon was coming from its supply chain. So it reached down to all its 100,000
vendors — and their vendors and their vendors — and told them that reducing
carbon footprints — reducing energy — will save money.

Everyone knows that is what Wal-Mart is all about.

“And vendors are listening,” said Tom Rooney, CEO of SPG Solar in Novato, California,
one of the largest solar installers in the country. “We are seeing renewed and
intense interest in industrial- and commercial-scale solar because of Wal-Mart
and Proctor and Gamble and other companies are showing their suppliers how to
change their shipping, packaging, storing, selling, heating, cooling, disposing of,
recycling and other practices to squeeze energy out of the supply chain and save
money. And solar is a big part of that.”

Not that many need much coaxing: Financial incentives for solar today are so
strong that many companies are essentially getting free energy — and more –
by buying a new solar array from the money they will save from lower energy bills.
And having a big chunk left over.

Now on top of that, the largest companies in the world are saying solar and other
renewables have to be a part of their supply chain. By some estimates, 1 in 3
dollars worldwide is associated with a company that does business with Walmart.
So, if you shift Walmart and its suppliers, the global economy shifts with it,
says R. Paul Herman at hipinvestor.com. Or as the New York Times puts it: “because
of its size and power, Wal-Mart usually gets what it wants.”

And Wal-Mart wants renewable energy.

Earlier this year, Wal-Mart sent its vendors a 15 part questionnaire to determine
what their companies were doing to become more sustainable. Also leading the
effort is Wal-Mart’s “Sustainability Index.”

Scholars from around the world are gathering at the Universities of Arizona and
Arkansas to create this new measure of the energy created — and wasted — during
the life cycle of a product found at Wal-Mart.

It won’t be ready for at least another year.

“But that doesn’t matter,” says Rooney. “No one is fighting Wal-Mart or complaining
about the reporting that this new index requires. Just the opposite: They are
racing to outdo each other, and surpass Wal-Mart’s expectations. Right now.
Not next year. “

And why not:

In May, the world’s largest consumer product company, Proctor and Gamble, announced
its own, similar, sustainability program for its vendors. Joining IBM, GE, and
other corporate giants on the sustainability train.

The results are already showing up on the bottom line:

“Perhaps more than any other company, Wal-Mart has pursued this approach,” said
the Harvard Business Review of Wal-Mart’s new vision of sustainability. “The
payoffs are already showing up: One of the Sustainable Value Networks, tasked
with fleet logistics, came up with a transportation strategy that improved efficiency
by 38%, saving Wal-Mart more than $200 million annually and cutting its greenhouse
gas emissions by 200,000 tons per year.”

Wal-Mart: Not just for beating up anymore. Or maybe we are just seeing the world’s
first quintuple play.
