      HomeBiogas, an Israel-based startup, has created an affordable and compact anaerobic digester that converts organic waste into cooking gas and liquid fertilizer. Home wastes like food scraps, kitchen trash and pet manure no longer have to go to waste.
      Here’s how it works: after the HomeBiogas system is fed organic matter, microorganisms break down the biodegradable material in the absence of oxygen. The end product is biogas and biofertilizer.

    • LED Lights to Cut
      60-Watt Bulb to Five Watts

      LED Energy Cutter

      Philips has cut the amount of power of its overhead Light-Emitting Diode (LED) tube light in half, a sign of continuing improvements in LED lighting geared at displacing incumbent technologies.
      The company says it has built a prototype of a tubular overhead LED light that produces 200 lumens of light with a watt of power. Its current products produce light at 100 lumens per watt, about the same as florescent tube lights. Even though the price of LEDs will be higher, Philips thinks that they can start to displace more of the florescent tube lights that are everywhere from office buildings to parking garages based on energy savings.

    • Drying Clothes Without Heat

      It could make your home safer and more energy efficient. It could be as affordable as your current clothes dryer.
      "It consumes almost 5 to 10 times less energy," said Ayyoub Momen, a scientist with the laboratory better known as one of the birthplaces of the atomic bomb. The laboratory, under the U.S. Department of Energy, now conducts research into clean energy and national security problems.
      Momen stumbled on a technology that uses vibrations, rather than heat, to dry clothes. It uses ultrasonic transducers to dry the fabric. The vibrations turn the water into a cold mist.

      Smart Window Glass

      Melbourne: Scientists have developed a new solar paint that can absorb water vapour and split it to generate hydrogen - the cleanest source of energy.

      The paint contains a newly developed compound that acts like silica gel, which is used in sachets to absorb moisture and keep food, medicines and electronics fresh and dry.
      However, unlike silica gel, the new material, synthetic molybdenum-sulphide, also acts as a semi-conductor and catalyses the splitting of water atoms into hydrogen and oxygen.

      A Geothermal Loop System sits securely in the earth underneath your home.
      It's zig-zag grid of underground pipe acts like a giant, low-energy heating & cooling machine. The system transfers air, water, or coolant through hundreds of feet of underground plumbing. After passing that media through the plumbing, the air, water, or coolant reenters your building, passing over your HVAC's heating & cooling coils and saving you about 80% on your #1 energy expense.........

    • It's the Cool Tube

      With the world getting hotter, finding energy-efficient ways to cool down is more important than ever. A team of researchers from the University of British Columbia, Princeton University, the University of California, Berkeley and the Singapore-ETH Centre plan to help us do just that with the ‘Cool Tube’.
      Air conditioning can be a blessing in the hot summer months, but they also consume a lot of power. Added up on a city- or country-wide scale this translates to a huge drain on our grids and vast quantities of CO2 emissions. Air conditioning can also contribute to respiratory complications by keeping germs in suspension in the air (by keeping it in constant motion).
      The team behind Cold Tube wanted to change how we manage our personal temperature during such times, and their approach doesn’t involve cooling or moving air at all.

      Algae Powered Energy Cell


      Green computing is taking on a whole new meaning: researchers at the University of Cambridge have developed an algae-filled power cell that has successfully powered a microprocessor for a year now — and it’s still going.
      Synechocystis is a widespread species of photosynthesizing blue-green algae. As it captures energy from the sun, these algae generate a very small electrical current. The cell, after being filled to the brim with Synechocystis, uses an aluminum electrode to tap into these biologically-generated currents and power a microprocessor — the part of a computer that does the computing.

      Solar Chimney
      In “Solar Chimneys & Solar Updraft Towers,” we described these solar solutions as ancient passive solar technology, whereby natural heat convection processes are harnessed to provide ventilation. The basic idea is to harness the power of natural ventilation to increase the turnover rate for air within a building by amplifying natural convection processes through the use of a (typically external) vertical shaft that heats up rapidly when exposed to the sun.
      RMIT University researchers have energetically enhanced the safety aspect and designed a solar chimney optimized for a 6-fold increase in fire safety — as well an increasing energy saving.
      As a passive solar heating and cooling technology, this type of ventilation and/or cooling system has seen widespread use in the region encompassing and surrounding Greater Iran, throughout the Middle East and North Africa, and in Roman Europe throughout the millennia. It’s time to spread its use with the advancements of RMIT University and the Australian town of Kingston, Victoria. This could be a turning point towards expansion.

      It doesn't need batteries or sunlight and costs nothing to run. It takes seconds to lift the weight that powers GravityLight, creating 20 minutes of light on its descent.

    • Printable Solar
      A University of Toronto engineering innovation could make printing solar cells as easy and inexpensive as printing a newspaper.
      Dr. Hairen Tan and his team have cleared a critical manufacturing hurdle in the development of a relatively new class of solar devices called perovskite solar cells. This alternative solar technology could lead to low-cost, printable solar panels capable of turning nearly any surface into a power generator.
    • Emissions Absorbing Sculpture
      Solar Windows Tech

      Kengo Kuma just unveiled a spiraling, air-purifying sculpture that can absorb the emissions produced by 90,000 cars in a year. Kuma’s “Breath/ng” is made from a cutting-edge fabric with a nano-molecule activated core that separates and absorbs toxic molecules. Developed by Anemotech, this pollution-neutralizing material uses the natural flow of air to purify the surrounding environment.

      The Un-Solar Cell
      Night Solar Panels

      Jeremy Munday, a professor in the Department of Electrical and Computer Engineering at the University of California (UC) Davis says “A regular solar cell generates power by absorbing sunlight, which causes a voltage to appear across the device and for current to flow. In these new devices, light is instead emitted and the current and voltage go in the opposite direction, but you still generate power.”
      “You have to use different materials, but the physics is the same.”
      The whole system relies on the property of physical bodies to radiate heat to their surroundings (if these are cooler). In essence, it works as a reverse to a traditional solar cell, which absorbs light and energy from the sun.

    • Out of the Box
      Thinking Leads
      to Energy Efficiency Breakthrough
      Out of the box thinking

      The term “out of the box thinking” seems a little overused, but in this case it appropriately describes the unique thought process that has led one research team to a fantastic discovery. What if there was a way to control magnetic waves the way we control electric current?
      Research led by a University of Sussex scientist has turned a 156-year-old law of physics on its head in a development which could lead to more efficient recharging of batteries in cars and mobile phones.
      Dr Jordi Prat-Camps has for the first time demonstrated that the coupling between two magnetic elements can be made extremely asymmetrical. Working with colleagues from the Austrian Academy of Sciences and University of Innsbruck, Dr Prat-Camps’ research rips up the physics rule book by showing it is possible to make one magnet connect to another without the connection happening in the opposite direction.

      Game Boy Look-Alike Runs On PV
      and Button Smashes

      The prototype handheld game console, built by researchers at Northwestern University in Evanston, Ill., and Delft University of Technology in the Netherlands, harvests enough energy from key smashing and sunlight to run games like Tetris and Super Mario Land.
      Such a battery-free setup, presented September 15 at the virtual UbiComp conference, could one day help curb electronic waste from handheld games and other mobile devices.

      Solar Trees

      A solar tree is a structure resembling a tree that generates solar energy using photovoltaic (PV) panels. It employs principles of biomimicry, using a natural system—in this case the form of a tree—to help solve a pressing global challenge: Replacing greenhouse gas-emitting energy sources like coal, oil, and gas with renewable energy.
      These attention-grabbing installations generally have a sturdy metal, plastic, or stone base that extends up and out into “branches” on which solar panels are mounted. Beyond this basic structure, there is great diversity in the design of solar tree units, reflecting innovative responses to particular environments, climates, and local energy needs.

      Uberizing Your Roof

      The Uber model is changing America. First it made a business out of the family car. Then it made a business out of the spare room or vacation house.
      Soon it might make a business out of the roof over your head.
      That is the dream of a group of hugely successful entrepreneurs who see roofs as the next big monetization of a widely held capital asset.
      This group, which at present chooses to remain anonymous, believes that with the right communications network and smart computer linkage, the nation’s sun-trapping roofs could become a new source of electricity and, if connected to in-home batteries, a virtual power plant of scale and reliability.
