Spread the Word # 3 : Incredible innovations that improved the world in 2015 (from Mashable)

From their website:

"In early January, we saw Bill Gates drink clean water converted from sewer sludge and human waste by a special processor. In February, social workers and computer scientists came up with an algorithm to prevent the spread of HIV among homeless youth. In March, a research lab created a microchip that could actually help bridge the digital divide in developing countries. From a new sneaker that helps people with physical disabilities, to "nanosheets" that can absorb oil spills, to a bindi that delivers much-needed iodine to women in India, these are some of our favorite innovations that truly made a difference in 2015."

Below, the Help Club features three of their favorite innovations from the list.

**The lamps powered by plants**

"Approximately 42% of rural areas in the Peruvian jungle don't have electricity, according to Peru's latest National Household Survey conducted by the National Institute of Statistics and Information.

The Universidad de Ingeniería y Tecnología (UTEC), which is known for developing innovative technologies in response to pressing world issues, created the Plantalámparas — a lamp that runs on plant power and lights the small village of Nuevo Saposoa.

During photosynthesis, the plant's waste decomposes in the soil, producing electrons during oxidation. The UTEC team captures these electrons by using electrodes in the soil and storing it in batteries. This process can light the LED bulbs for up to two hours."

**The beehive that harvests honey on its own**

"Two Aussie inventors created the Flow Hive beehive, which allows beekeepers to get honey on tap without opening the beehive and disturbing the bees.

The innovative hive's frames consist of partially formed honeycomb cells, which lets the bees complete the comb with their wax before filling the cells with honey. Beekeepers then need only turn a handle to split the cells vertically, so the honey can drip down to the base of the frame and out of the hive.

The Flow Hive has a clear window so you can watch the bees, which the inventors say can help with scientific research without disturbing them."

**The machine that converts poop into clean drinking water**

"Approximately 2.4 billion people around the world didn't have access to basic, safe sanitation in 2015, while more than 660 million people used unimproved drinking water sources.

The Gates Foundation talked to engineers to figure out how we could use technology to tackle these issues. Peter Janicki, CEO of Janicki Bioenergy, developed a machine (shown in the video above) that converts sewer sludge into clean drinking water, electricity and pathogen-free ash in a matter of minutes.

The processor can help developing countries both by providing clean water and energy, as well as employing entrepreneurs to run it in the regions where it's needed most."

Thanks, as always, to the helpers of the world.
