Loon – Balloon Enabled Internet

Project Loon, from Google:

The Internet is one of the most transformative technologies of our lifetimes. But for 2 out of every 3 people on earth, a fast, affordable Internet connection is still out of reach.

We believe that it might actually be possible to build a ring of balloons, flying around the globe on the stratospheric winds, that provides Internet access to the earth below. It’s very early days, but we’ve built a system that uses balloons, carried by the wind at altitudes twice as high as commercial planes, to beam Internet access to the ground at speeds similar to today’s 3G networks or faster. As a result, we hope balloons could become an option for connecting rural, remote, and underserved areas, and for helping with communications after natural disasters.

Google testing out this system now in New Zealand. If they can get it to work they plan to use ballons to provide wireless internet access to hundreds of millions, or even billions, of people that don’t have access now. These ballons would float about 20 km above earth in the stratosphere (so well above where commercial airline traffic) and they are really working somewhat like to satellites.

Though ballons are much cheaper to put in place than satellites they also offer significant problems as they get blow around by wind (which is why they haven’t been used before and why Google is going to experiment to see if they can get it to work). The ballons will use solar power and be controlled by a mission control to move into different wind zones to position themselves.

Appropriate Technology Health Care Solution Could Save 72,000 Lives a Year

We need more medical solutions that serve the majority of humanity instead of just the rich. Some medical research is innately costly and therefore require large costs to pay back the investment. But too little concern is shown for solutions that help people (with so much focus only on solutions that will make organizations rich).

Cheap vinegar test cut cervical cancer deaths in India; could help many poor countries

This low-tech visual exam cut the cervical cancer death rate by 31 percent, the study found. It could prevent 22,000 deaths in India and 72,600 worldwide each year, researchers estimate.

More progress against cervical cancer may come from last month’s announcement that two companies will drastically lower prices on HPV vaccines for poor countries. Pilot projects will begin in Asia and Africa; the campaign aims to vaccinate more than 30 million girls in more than 40 countries by 2020.

India continues to invest in medical research for solutions that are affordable to a majority of the world. The rich health care companies largely neglect the majority to focus on the most wealthy.

Clay Water Filters for Ghana

Pure Home Water, Ghana manufactures and distributes AfriClay Filters in an effort to bring clean water to 1 million people. So far they have delivered filters to provide 100,000 people clean water.

The process is simple. Water is placed in a clay filter and gravity pulls the water through the pores left in the clay during firing.

Sediment and bacteria are filtered out in several ways:

  • Physical straining: the particles are too large to fit through the pores in the clay
  • Sedimentation or adsorption: particles come to rest on or stick to the clay
  • Inertia: friction in the pores keeps the particles from passing through

Bacteria are also killed by a coating of colloidal silver (a disinfectant), which we apply to all filters that pass our quality control tests. While sediment and bacteria are filtered out, the molecules of water are small enough to pass through the pores in the clay.

The filters are sold to those who will use them. The effort has shown a willingness to pay by villagers in remote Northern Ghana (those earning < US$1/day). I imagine (I am just guessing) the prices are subsidized; in the last decade more (most?) appropriate technology solutions will have those benefiting pay something for the benefits they receive.

My nephews are working on a similar effort in India, using bio sand filters, I plan to post more on that later. There is current a campaign to help fund the delivery of water filters to Indian villages.

Building A Better Bed Bug Trap Using Bean Leaves

Building A Better Bed Bug Trap

An old folk remedy involving hairy bean leaves strewn around the bedroom may have a new life as a modern bed bug trap, according to new research from the University of California, Irvine and the University of Kentucky.

Although its mechanisms weren’t known at the time, the tactic dates back to at least 1678, when the English philosopher John Locke wrote of placing kidney bean leaves under the pillow or around the bed to keep bed bugs from biting as he traveled through Europe.

In the early twentieth century, the approach was also common throughout the Balkans, according to a 1927 report from the Imperial and Royal Austro-Hungarian Army. That report suggested the leaves stunned the bloodsucking bugs as they traveled from hiding places to their sleeping hosts during the night; in the morning, the bug-covered leaves were removed and burned.

“The inconvenience of bean leaves is that not everyone wants them scattered around their bed room.” Synthetics mimicking the surface of the bean leaf, however, could be placed “as a ring around the bed legs, a floor mat at the door, a strip on the bed board, it could be something one put’s in one’s suitcase,”

Very cool. The chemical assault on bed buds is failing all over the world. A new vector to assist in the fight against bed bugs will be most welcome. It is interesting to learn the scientific reasons that explain why some folk remedies work.

Solar Powered Water Jug to Purify Drinking Water

Deepika Kurup, a 14-year-old New York student, won the Discovery Education 3M Young Scientist Challenge for her invention of a solar-powered water jug that changes dirty water into purified drinking water. She won the top prize of $25,000.

During “the 5 minutes of my presentation 15 children have died from lack of clean drinking water.”

I am thankful we have kids like this to create solutions for us that will make the world a better place. We rely on hundreds of thousands of such people to use science and engineering methods to benefit society.

Toyota Human Support Robot

Toyota continues to develop their partner robot initiative. Demographics in Japan make a compelling case for the need to provide solutions to those who need assistance to support independent living.

The aim is to contribute to the maintenance and improvement of quality of life.

In cooperation of the Yokohama Rehabilitation Center, Toyota conducted experiments for disabled people, using HSR in their homes, in 2011. Toyota has been integrating the feedback to the design, based on actual user experience.

The Human Support Robot (HSR) can pick up something on and bring it to the person. Also it can do small tasks such as opening the curtains.

Controlling the robot can be done easily, by using the voice recognition function or using a tablet control. In addition, Toyota is designing it to directly assist the person, helping them get into and out of a bathtub, for example.

They are also developing new features for remote viewing and remote operation (to provide off site help to make the robot more useful). They are working with health care professionals, including nurses, and research institutions aimed at practical use for such a robot.

Toyota, along with several other Japanese companies, continue to invest a great deal to create personal care robots.

Man in Coma for 7 Years was Given a Sleeping Pill and Woke Up

Lazarus pill miracle for E Cape man, 9 September 2012

After reading a report in City Press last month, his wife, Nomfundo, insisted that he be given a prescription for the sleeping pill Stilnox, which has the opposite effect on those with brain injuries.

It worked – and brought him out of a seven-year coma.

But on August 12, family friend Nceba Mokoena came across an article in City Press about a miracle recovery made by another car crash victim, hundreds of kilometres away in Gauteng.

Louis Viljoen was given the sleeping pill by chance by his mother, Sienie.

She had noticed he wasn’t sleeping peacefully and asked her doctor if she could give him half a sleeping tablet. After she did, Louis opened his eyes and said “Hello Mamma”, his first words in five years.

Very cool anecdote and example that modern medicine has many miraculous cures but the medical system can’t always use them as well as we would hope. Even with all the knowledge we have today just getting that information into the right doctor’s minds is very hard. And the complexity of diagnoses and interactions makes medical care still an art as well as a science.

So is this just some freak accident. Partially, in the mother giving her son a sleeping pill to reduce his seeming restlessness in the coma. But the effect of Stilnox in bringing coma victims out of a coma has been documented previously.

Reborn from persistent vegetative state, 12 September 2006

Four three years, Riaan Bolton has lain motionless, his eyes open but unseeing. After a devastating car crash doctors said he would never again see or speak or hear. Now his mother, Johanna, dissolves a pill in a little water on a teaspoon and forces it gently into his mouth. Within half an hour, as if a switch has been flicked in his brain, Riaan looks around his home in the South African town of Kimberley and says, “Hello.” Shortly after his accident, Johanna had turned down the option of letting him die.

Three hundred miles away, Louis Viljoen, a young man who had once been cruelly described by a doctor as “a cabbage”, greets me with a mischievous smile and a streetwise four-move handshake. Until he took the pill, he too was supposed to be in what doctors call a persistent vegetative state.

Across the Atlantic in the United States, George Melendez, who is also brain-damaged, has lain twitching and moaning as if in agony for years, causing his parents unbearable grief. He, too, is given this little tablet and again, it’s as if a light comes on. His father asks him if he is, indeed, in pain. “No,” George smiles, and his family burst into tears.

It all sounds miraculous, you might think. And in a way, it is. But this is not a miracle medication, the result of groundbreaking neurological research. Instead, these awakenings have come as the result of an accidental discovery by a dedicated – and bewildered – GP. They have all woken up, paradoxically, after being given a commonly used sleeping pill.

Medical care is still today an extremely difficult area where highly trained and continuously learning doctors still have a great deal of trouble keeping up with the latest medical knowledge.

Citizen Science: Use Your Smart Phone to Help Scientists

10 Ways You Can Use Your Smartphone to Advance Science by Matt Soniak

Scientists have started to use the abilities and prevalence of smartphones to their advantage, creating apps specifically for their studies and crowdsourcing observation and data collection. When almost everyone has an Internet connection, a camera, and a GPS unit right in their phone, almost anyone can gather, organize, and submit data to help move a study along.

The Indicator Bats Program (iBats), a joint project of the Zoological Society of London’s Institute of Zoology and The Bat Conservation Trust, got its start with a couple of researchers working in Transylvania (of course) in 2006. The idea of the project is to identify and monitor bat populations around the world by the ultrasonic echo-location calls they use to navigate and find prey.

The goal of Project NOAH (Networked Organisms and Habitats) is pretty ambitious: “build the go-to platform for documenting all the world’s organisms.” Their app has two modes. “Spottings” lets you take photos of plants and animals you see, categorize and describe them and then submit the data for viewing on NOAH’s website and use by researchers for population and distribution studies.

Invasive plants and animals can crowd out natives, compete with them for food sources and alter the fire ecology of an ecosystem, disrupting its natural balance. Researchers and programmers from UCLA, the Santa Monica Mountains National Recreation Area and the University of Georgia have teamed up to create the What’s Invasive citizen science program and smartphone app. Volunteers can use the app to look up lists of the top invasive species in their area, created by National Park Service rangers and biologists. If they spot a plant or animal from the list, they submit a geo-tagged observation, with optional picture and text notes, so that scientists can locate, identify, study try to remove the species.

Great stuff.
