If you don’t understand electrical safety, eye safety and or pressure cooker safety …. do not even try this ! Before I show you the tools involved … Allow me to go over some tactical reasoning. Janice Kelsey & Jody Spangler. Paper-thin printed solar cells could provide power for 1.3 billion people. The cost of solar power has declined dramatically over the past few decades, from $40 per watt in 1977 to $0.74 per watt in 2013.
This trend is expected to accelerate as improvements in efficiency and new technologies come online. This is good news for citizens of developed countries who want to make the switch to a cleaner and increasingly cheaper energy source. The shift to solar may be most dramatic for those living in developing countries. Thanks to inexpensive printed solar cells, 1.3 billion people currently without electricity may be able to plug in for the first time.
Maasai women are the new solar warriors of Africa. The Maasai are a semi-nomadic pastoral tribe spread across Kenya and Tanzania, and globalization has not been kind to them.
Vulnerable to wildlife that steal their livestock and powerless after the sun goes down, many Maasai often have to walk many kilometers just to charge their phones. But a new project spearheaded by Green Energy Africa has brought solar energy to 2,000 homes in Naiputa county alone, and put new power into the hands of women who sell affordable solar installations. Green Energy Africa started the 7-month Women Entrepreneurship in Renewable Energy Project (WEREP) in September 2014 with a goal “promote inclusive participation of women and youth in development through solar energy” while bringing much needed energy to people living in Kenya’s Kajiado and Makueni counties. The group reports only 23 percent of Kenyans have access to the national electricity grid, while only 5 percent of rural communities are connected. A couple years ago, researchers at the Hebrew University of Jerusalem released their finding that a potato boiled for eight minutes can make for a …

Make a Biogas Generator to Produce Your Own Natural Gas - Renewable Energy. You can use many household organic “waste” materials to produce your own natural gas for cooking, lighting, and space and water heating.
This gas, known as “biogas,” can also replace fossil-based natural gas to fuel an engine or an absorption cooling system, such as a gas refrigerator or chiller. Some gasoline engines are designed for or can be modified for use with natural gas, propane or biogas. Diesel engines can accept up to 80 percent biogas. Biogas is a mixture of primarily flammable gases — mostly methane — along with carbon dioxide that forms anywhere organic material decomposes anaerobically (without oxygen), such as in water, deep in a landfill, or in the guts of animals, including you.
I prefer the term “generator” for the system, because it conveys the intention of producing something. Biogas and How to Make a DIY Anaerobic Digester (Video) Image credit: The Urban Farming GuysBiogas and anaerobic digestion made number one in HowStuffWorks' list of wacky alternative energy, and poop-to-energy biogas projects have proven popular on Discovery News too.
From biogas in Haitian slums to green gas being sold direct to UK consumers, there are plenty of examples of innovative projects turning biodegreadable waste into both energy and fertilizer. But how can someone at home get a piece of the action? The Urban Farming Guys have just released a great video showing how they built a DIY biogas digester using little more than some tanks, piping, rubber seals and a grinder. Oh, and a whole load of cow poop. Biogas at home- Cheap and Easy. Georgia FACES. University of Georgia researcher Gary Hawkins looks at rotting fruits and vegetables differently than most people.
Where they may see useless balls of moldy fuzz, he sees fuel. As they break down, fruits and vegetables can be harvested for methane, or natural gas, he said. This gas can be used to heat greenhouses, shops or homes. Hydro Pico- Small Power Source For Remote Communities. * None of the following is allowed in American streams.
Around 4 billion people still have no source of electric power for basic lighting, charging phones, charging batteries and energy efficient appliances ….etc. Meet The Fuel of the Future: Bugs. Archaean bacterium Credit: Corbis In talking to ARPAe chief Arun Majumdar last week, I asked him about the future of transportation fuels.
Even with more hybrids and electric vehicles on the road, the U.S. Energy Information Administration says the American driver will rely on liquid fuels for the next 20 years. Corn-based ethanol needs big subsidies and is of dubious environmental benefit. So to break the stranglehold of foreign oil, scientists and engineers are developing something called electro-fuels.

SCIENCE CHANNEL: Future Transportation A team at North Carolina State University is combining enzymes from one microbe that grows at 75 degrees Celsius (167 F) with a second one that feeds off hydrogen.
