Human waste as sustainable energy? These high schoolers made it happen.

True
Green Mountain Energy

Leroy Mwasaru was a high school student at Kenya's prestigious Maseno School when a dorm room renovation created an unfortunate situation.

The school's outdoor latrines overflowed into the local water supply.

Understandably, this made some people quite upset. But Mwasaru saw this as an opportunity to turn something revolting into a revolution.

If he could redirect the overflowing human waste, it could give them cleaner water and help the school save money on fire and electricity.

See, at that same time, his school was spending a lot of money on firewood, which, like many Kenyan buildings, it used to fuel its kitchens, heat, and lights. It can be labor intensive to gather all that wood — and it's even more expensive to buy it.  Plus, all the soot and ash it creates is not good for the staff to consume on such a regular and large-scale basis.

So Mwasaru thought — why not use a biogas digester instead?

In his sophomore year biology class, he had learned how these digesters can harvest natural bacterial byproducts, such as human waste and turn it into natural gas energy through a process called anaerobic digestion.

"I initially researched renewable energy and biogas [digesters] just to satisfy my intellectual curiosity," Mwasaru explains over email. "After a while, it became so much more than biology — there was chemistry too. It got to solving problems my local community faced, such as lack of access to affordable renewable energy."

Mwasaru recruited a group of friends, and over the next year, they built a working prototype biogas digester for the school.

His initial proposal was met with some level of resistance from the community. "I want to burn our poop to fuel the kitchen" isn't exactly the kind of thing anyone wants to hear from a high school student.

"That's what pushed me to make sure it came to pass, and made sure it benefited them. Sometimes it's the bad energy you get that pushes you to do stuff," Mwasaru says.

Their earliest tests began by collecting raw "fuel" in the form of cow dung, food waste, fresh cut grass, and eventually, water.

These components were then mixed together into a paste...

... that they poured into a plastic vessel — the digester itself.

The natural bacteria contained in all these ingredients was more than enough to spark the anaerobic process as it broke down the organic waste materials.

Over time, the dense physical waste drops down to the bottom of the container, separating from the bacteria's combustible gas byproduct, which can then be collected and used for energy.

Lighting a burner with harvested biogas.

Granted, there were a few hiccups along the way. "I have to credit the failures we have had," Mwasaru says. "Our very first bio-digester prototype had too much gas and exploded, so we had to re-learn and re-invent the model until it was stable."

After a little trial and error, Mwasaru and friends completed their first working prototype — and it was good enough to earn them a coveted spot at the Innovate Kenya startup camp.

See this video here of how his small-scale prototype worked here:

It demonstrated the basic way that the anaerobic process could be contained within a single plastic vessel with pipes to move the gas along, while directing all the other organic waste into the ground. It wasn't enough to power the entire school on its own, but it was a start.

Then, at the startup camp, the teens had the opportunity to work alongside student engineers from MIT to hone and refine their project.

In fact, the product that this high schooler devised was so impressive that it earned them funding from Global Minimum — a charitable organization that encourages young innovators and leaders in Africa — to build a second,  improved prototype.

"Leroy seeks to understand everything he doesn't know by asking probing questions, taking notes and experimenting to learn," said David Moinina Sengeh, an MIT Researcher who also serves as Global Minimum's board president, in an interview with CNN. "His curiosity to explore and learn from doing within a motivation to bring broader social change is something that we hope to see in all our youth and frankly everyone."

As work began on the next, larger prototype, Mwasaru had the opportunity to travel to America to speak at prestigious conferences, such as Techonomy and One Young World.

He also returned home to the small village where his father still lives and helped to install a biogas digester there too, using the dung from his father's six cows. It generates enough gas for him to share with the other 30 houses in the village. Plus, it made things easier for the women in the village — another cause that Mwasaru is passionate about — who were sometimes spending up to 24 hours a week collecting firewood.

"When I deployed the Biogas pilot in my rural home, I mainly envisioned it as a way of leveraging sustainable renewable energy to make the world a better place through my community," Mwasaru says. "Now I believe through our activities that other sectors [such as women empowerment] could benefit immensely from the approach."

The biogas digester project has since grown into a full-fledged startup/social enterprise called Greenpact — with Mwasaru serving as its CEO.

Since graduating from Maseno School, Mwasaru has taken a gap year to focus on the company's mission to address the lack of affordable renewable energy and proper sanitation that affects some 9 million Kenyan households.

He hopes to steer the company into an impactful organization that offers a wide range of products and services, including biogas digesters. He does have plans to go to college — but for now, Greenpact is his priority.

"I didn't see myself focusing on renewable energy but after doing some work in the field I figured out that I am actually more into renewable energy than I had imagined," Mwasaru says.

Now he's determined to show the world how to turn energy into opportunity and vice versa. The only way to do that is to stop seeing things as waste and start seeing them as resources instead.

Expert says there's only one laundry cycle you ever need, no matter what's being washed

Straight from Patric Richardson, the "Laundry Guy" himself.

Because who can keep up with which laundry settings is for which item, anyway?

Once upon a time, our only option for getting clothes clean was to get out a bucket of soapy water and start scrubbing. Nowadays, we use fancy machines that not only do the labor for us, but give us free reign to choose between endless water temperature, wash duration, and spin speed combinations.

Of course, here’s where the paradox of choice comes in. Suddenly you’re second guessing whether that lace item needs to use the “delicates” cycle, or the “hand wash” one, or what exactly merits a “permanent press” cycle. And now, you’re wishing for that bygone bucket just to take away the mental rigamarole.

Well, you’re in luck. Turns out there’s only one setting you actually need. At least according to one laundry expert.

While appearing on HuffPost’s “Am I Doing It Wrong?” podcast, Patric Richardson, aka The Laundry Evangelist, said he swears by the “express” cycle, as “it’s long enough to get your clothes clean but it’s short enough not to cause any damage.”

Richardson’s reasoning is founded in research done while writing his book, “Laundry Love,” which showed that even the dirtiest items would be cleaned in the “express” cycle, aka the “quick wash” or “30 minute setting.”


Furthermore the laundry expert, who’s also the host of HGTV’s “Laundry Guy,” warned that longer wash settings only cause more wear and tear, plus use up more water and power, making express wash a much more sustainable choice.

Really, the multiple settings washing machines have more to do with people being creatures of habit, and less to do with efficiency, Richardson explained.

“All of those cycles [on the washing machine] exist because they used to exist,” he told co-hosts Raj Punjabi and Noah Michelson. “We didn’t have the technology in the fabric, in the machine, in the detergent [that we do now], and we needed those cycles. In the ’70s, you needed the ‘bulky bedding’ cycle and the ‘sanitary’ cycle ... it was a legit thing. You don’t need them anymore, but too many people want to buy a machine and they’re like, ‘My mom’s machine has “whitest whites.”’ If I could build a washing machine, it would just have one button — you’d just push it, and it’d be warm water and ‘express’ cycle and that’s it.”

When was the last time you washed you washing machine? "Never" is a valid answer.

According to Good Housekeeping, there are some things to keep in mind if you plan to go strictly express from now on.

For one thing, the outlet recommends only filling the machine halfway and using a half dose of liquid, not powder detergent, since express cycles use less water. Second, using the setting regularly can develop a “musty” smell, due to the constant low-temperature water causing a buildup of mold or bacteria. To prevent this, running an empty wash on a hot setting, sans the detergent, is recommended every few weeks, along with regularly scrubbing the detergent drawer and door seal.

Still, even with those additional caveats, it might be worth it just to knock out multiple washes in one day. Cause let’s be honest—a day of laundry and television binging sounds pretty great, doesn’t it?

Convertible sleeping bags turn into insulated tents for people experiencing homelessness

Innovation at its best.

via Pinterest

A demonstration of the Satellite Shelter.

When blizzards line up to rip through the Northeast, schools close, flights are canceled, and people even board up their houses. Though missions and homeless shelters do what they can to provide safety to those who have no homes to go to, thousands of people still have to weather the cold outside.

At Carnegie Mellon University's 2015 Impact-a-Thon, students were challenged to provide a temporary low-cost shelter for homeless people during the winter.

One team of students came up with the "Satellite Shelter," an insulated sleeping bag that converts into a tented structure. The students used mylar, a reflective material frequently used in greenhouses and space blankets, and wool blankets to ensure the shelter would keep anyone in it safe from the cold.

"We wanted to make sure it was super-portable and durable so that it's easy to carry," said student Linh Thi Do, who worked on the project. "We have wheels on it so it's easy to move from place to place."

Solutions like this one are handy in an emergency. Perhaps, however, other cities should take note of the city of New Orleans' success in providing long-term housing solutions for its homeless veterans. The only perfect solution to homelessness is giving people permanent homes to go to at night.

What will Earth look like if all its land ice melts? Here's your answer.

Climate change isn't pretty.

via Business Insider Science/YouTube.

A map of the United States post land-ice melt.


Land ice: We got a lot of it.

Considering the two largest ice sheets on earth — the one on Antarctica and the one on Greenland — extend more than 6 million square miles combined ... yeah, we're talkin' a lot of ice.

But what if it was all just ... gone? Not like gone gone, but melted?

If all of earth's land ice melted, it would be nothing short of disastrous.

And that's putting it lightly.

This video by Business Insider Science (seen below) depicts exactly what our coastlines would look like if all the land ice melted. And spoiler alert: It isn't great.

Lots of European cities like, Brussels and Venice, would be basically underwater.

In Africa and the Middle East? Dakar, Accra, Jeddah — gone.

Millions of people in Asia, in cities like Mumbai, Beijing, and Tokyo, would be uprooted and have to move inland.

South America would say goodbye to cities like Rio de Janeiro and Buenos Aires.

And in the U.S., we'd watch places like Houston, San Francisco, and New York City — not to mention the entire state of Florida — slowly disappear into the sea.

Business Insider based these visuals off National Geographic's estimation that sea levels will rise 216 feet (!) if all of earth's land ice melted into our oceans.

There's even a tool where you can take a detailed look at how your community could be affected by rising seas, for better or worse.

Although ... looking at these maps, it's hard to imagine "for better" is a likely outcome for many of us.

Much of America's most populated regions would be severely affected by rising sea levels, as you'll notice exploring the map, created by Alex Tingle using data provided by NASA.

Take, for instance, the West Coast. (Goodbye, San Fran!)

Or the East Coast. (See ya, Philly!)

And the Gulf Coast. (RIP, Bourbon Street!)

I bring up the topic not just for funsies, of course, but because the maps above are real possibilities.

How? Climate change.

As we continue to burn fossil fuels for energy and emit carbon into our atmosphere, the planet gets warmer and warmer. And that, ladies and gentlemen, means melted ice.

A study published this past September by researchers in the U.S., U.K., and Germany found that if we don't change our ways, there's definitely enough fossil fuel resources available for us to completely melt the Antarctic ice sheet.

Basically, the self-inflicted disaster you see above is certainly within the realm of possibility.

"This would not happen overnight, but the mind-boggling point is that our actions today are changing the face of planet Earth as we know it and will continue to do so for tens of thousands of years to come," said lead author of the study Ricarda Winkelmann, of the Potsdam Institute for Climate Impact Research.

If we want to stop this from happening," she says, "we need to keep coal, gas, and oil in the ground."

The good news? Most of our coastlines are still intact! And they can stay that way, too — if we act now.

World leaders are finallystarting to treat climate change like the global crisis that it is — and you can help get the point across to them, too.

A letter to my mother-in-law who spoiled my sons

"It's pointless to dwell on regrets, but I often think about how I had it all wrong. I was so wrong in how I perceived your generosity."

Tina Platamura


You always stole my thunder. You gave them everything they wanted. You never said no when they asked for anything.

Tina Platamura

A second helping of dessert. Candy before dinner. A few more minutes in the bath. Money for the ice cream truck.

I struggled to show you respect and appreciation while trying to make sure you didn't spoil my children. I thought you would turn them into “selfish brats" by giving them everything they wanted. I thought they might never learn to wait, to take turns, to share, because you granted their wishes as soon as they opened their mouths and pointed.

You held each one of my babies long after they fell asleep. Didn't you understand that I needed them to learn to fall asleep on their own?

You ran to them as soon as they made the tiniest sound. How would they ever learn to self-soothe?

I resented you for buying the best and most expensive gifts on their birthdays and on Christmas. How could I possibly compete with you?

"I thought they might never learn to wait, to take turns, to share, because you granted their wishes as soon as they opened their mouths and pointed."

And how they loved afternoons spent with you. You made their favorite things for dinner — three different meals for three different boys. And you always had a little surprise. A present, candy, or a special treat. I didn't want them to associate you with gifts and sweets. I thought they should love you for you. I tried to tell you this, but you wouldn't listen.

I spent a lot of time wondering why you did all these things and how I could get you to ease up. I know grandmothers are supposed to “spoil the kids" then send them home, but you were ... ridiculous.

Until you were gone.

I had to hold my boys and tell them that their grandma died. It didn't seem possible — you were supposed to be there for all the other special moments: proms, graduations, weddings. But they lost their grandma too soon and too suddenly. They were not ready to say goodbye.

During those years when I wished you'd stop spoiling them, I never thought about how much you loved them. So much that you showed it in every way possible. Your cooking. The gifts. The candy and sweets. Your presence. The way you could recount every detail of a special moment, whether it was a perfect catch in the outfield or a sweet and slightly off-key note sung at a school concert. Your grandmotherly love for them knew no bounds. Your heart poured love from every place possible — your kitchen, your pocketbook, your words, and your tireless arms.

It's pointless to dwell on regrets, but I often think about how I had it all wrong. I was so wrong in how I perceived your generosity.

My kids, now in their teens, miss you dearly. And they don't miss your gifts or your money. They miss you.

They miss running to greet you at the door and hugging you before you could step in. They miss looking up at the bleachers and seeing you, one of their biggest fans, smiling and enthralled to catch their eye. They miss talking to you and hearing your words of wisdom, encouragement and love.

If I could speak to you one more time, I would tell you that every time a precious moment steals my heart, every time I watch them arrive at a new milestone, and every time they amaze me with their perseverance, talents, or triumphs, I think of you. And I wish that they could have you back.

Come back and love them one last time, like no one else in the world but a grandmother could. Bring your sweets and surprises. Reward them with gifts for the smallest accomplishments. Painstakingly prepare their favorite meals. Take them anywhere they want to go. All and only because you love them.

Come back and see how much they've grown. Watch each boy becoming his own version of a young man. Be in awe with me as we admire how family, friendship, time, and love helped them grow so beautifully over the years.

The more I long for you to come back, though, the more I realize that in a way, you never left.

assets.rebelmouse.io

I understand now. I know you loved them in every way you could. I know that being their grandma gave you joy and purpose. And of course I know that you can't come back, but I do know that your love for them will always remain. Your love built them and sheltered them in ways that cannot be described. Your love is a big part of who they are and what they will become as they grow. For this, and for every treat and gift, and every time you held them too long or consoled them too much or let them stay up too late, I will always thank you.

And I will wish a million times that you could do it all again.

A popular optical illusion with a mindbending twist proves we can't trust our senses

Mind. Blown.

Curiosity Show/YouTube

The Ames window trick.

Optical illusions are universally beloved for how they trick our brains and blow our minds. There's a reason we enjoy magic shows and Escher paintings and are mesmerized by fake oases in the desert. We love seeing things that bend our perceptions of reality, and the science behind the magic always proves fascinating as well.

The Ames window is a pretty well-known optical illusion, but it's always cool to see. When spun, the angled window appears to oscillate back and forth instead of spin all the way around. But this video adds a twist that makes the effect even more mindbending—our brains simply can't process objective reality mixed with an optical illusion.


The YouTube channel Curiosity Show explains the science of the illusion and gives a DIY demonstration for making your own Ames window. But wait until the pen gets taped to the window and spun. This is some real-life magic right here. Mind. Blown.
