  • Eco-Brella: prototype development of the umbrella as harvester of solar and wind energies

    The familiar umbrella has been redesigned for power harvesting from renewable energy sources resulting in the Eco-Brella . Several engineering technologies are utilised: aerodynamics for fin design, mechatronics for power management, materials for thermoelectric and solar film, CAD for the layout, and heat transfer for human comfort. The result is a sustainable design capable of harvesting ...

  • Ships that harvest electrical power from ocean waves

    Electrical power generation from ocean waves is possible from ships that harvests wave energy through daily trips to offshore locations and that return back to port for the delivery of energy to the grid. Energy is stored locally on the vessel during harvesting phase and placed on the grid during periods of high demand (normally mid-day). Unlike conventional wave-power devices, the ships ...

  • Woody Biomass as renewable energy source

    In-depth analysis in Minnesota assesses the feasibility and cost-effectiveness of regional biomass generated electricity projects that tap into local feedstocks. The Center for Energy and Environment (CEE) in Minneapolis, Minnesota undertook a multiphase research project to create a framework that communities and legislators can use to determine the feasibility of biomass-generated electricity in ...

  • How to grow a solar energy garden

    Getting energy from the sun is a great idea. However, installing solar panels house-by-house is slow, costly and cumbersome, and downright inefficient if the goal is to bring solar to the masses. This problem troubled Paul Spencer after he built his own uber-efficient, custom solar home near Aspen, Colorado in 2004.  The engineer and serial entrepreneur wondered how he could replicate his ...

  • Entropy generation metric for evaluating and forecasting aircraft energy management systems

    A general Entropy Generation Minimisation (EGM) technique is applied to analyse the feasibility of energy recovery from aircraft avionics via thermoelectric (TE) devices. In employing this approach, a suitable control volume definition is chosen to evaluate the impact of an energy recovery system on the overall entropy generation of the aircraft over a mission. Only those systems which are ...

  • What Makes Biomass a Sustainable Energy Source?

    “Sustainability” is a major buzzword in the energy sector. In the face of climate change, national governments and global organizations like the United Nations continue to encourage the use of sustainable energy sources. In this blog, we’ll examine what makes biomass sustainable, specifically plant-derived biomass like wood pellets. Sustainable Resources: Wood ...

  • Biomass and Integration in Future Energy Systems and the Bioeconomy

    Biomass was the primary source of materials and energy until the industrial revolution set off a series of major changes around two hundred years ago. In the industrialized world fossil fuels became the primary source for energy in the forms of electricity and heat and provided almost all fuels for transport. However, biomass continued to maintain an important role in the economies in both ...

  • Walki biomass cover: easy cover-up improves drying process and energy content of energy wood

    Logging residue is an inexpensive and easily accessible source of biofuel, but to improve the energy content it must first dry on the ground and after that it can be stored in piles for several months. To shelter the piles from moisture through rain, snow and ice, Walki has developed a paper-based, waterproof cover that can be chipped and burned together with the residue. The importance of ...

  • Environmental impacts of ocean-energy systems: a life-cycle assessment

    Ocean-energy technologies — which harvest renewable energy from the sea — will have a significant role to play in a future low-carbon society. A recent life-cycle analysis of different ocean-energy devices has found that life-cycle environmental impacts are caused mainly by the materials used in the mooring, foundations and structures. Improving the efficiency and lifespan of the ...

  • Ocean Thermal Energy conversion and the company bringing it to market: peace for our children

    Two centuries ago, U.S. President John Adams advised us of the importance of observing our world with clear eyes, “Facts are stubborn things; and whatever may be our wishes and passions, they cannot alter the state of facts and evidence.” Though there are some facts we all would rather not face, one of those unpleasant truths is that there are places in the world where the need for ...

  • Following the fuel: How portable biomass energy generation may help rural communities

    The forests that surround many of California’s mountain communities tend to have an abundance of woody biomass and a pressing need for thinning to reduce fire danger. Revenue from selling forest residues to biomass power plants could help to support fuel reduction activities, but in many cases the nearest plant is so far away that hauling costs are prohibitive. The remoteness of such ...

  • How can we ensure the race for clean energy doesn’t leave the world’s poorest citizens behind?

    As in other places around the world, Mexico’s wind boom runs the risk of bypassing the poor, which is why we need new global standards. Wind power is booming in Mexico. With more than 3,200 megawatts in operation, the country is on par with Japan. By 2018 it expects to have ...

  • Ocean Thermal Energy conversion and the company bringing it to market: clean water for our children

    Water is the most life sustaining resource on earth. Essential to all aspects of our human lives, it serves as the key ingredient in food and drink, helps us fabricate clothes, landscapes our favourite places, drives economic growth and feeds agricultural development. Our bodies themselves are 70% water. This liquid of life keeps us hydrated, catalyses crucial chemical reactions within our cells ...

  • DOE Announces $15 Million In Funding For Algae-Based Biofuels And Bioproducts Research Projects

    On July 14, 2016, the U.S. Department of Energy (DOE), announced $15 million in funding for three projects that will work to improve algal biomass yields to reduce production costs of algae-based biofuels and bioproducts. The projects include Global Algae Innovations (San Diego, ...

  • Ground Source Heat Pumps

    In many buildings Ground Source Heat Pumps (GSHPs) provide an efficient solution for heating and cooling. Using low temperature latent heat which exists naturally below ground, GSHPs provide solutions by harvesting and transferring this energy for the benefit of the built environment. It is important to understand the feasibility of GSHP prior to designing a system. This guidance note has been ...

  • Biomass power generation in China

    “China is an agricultural country,” said Frank Miao. Farmers used to burn harvest waste, and the government decided to capture this energy by constructing a biomass power plant. At the end of 2006, the total biomass power generation capacity in China was approximately 2,200 megawatts (MW). The planned capacity of biomass power plants is 30,000 MW by 2020. Depending on the size of the plant, three ...

  • Wind power status, barriers, and opportunities

    In the wake of the oil crisis in the early 1970s, governments around the world were anxious to diversify energy supply away from fossil sources, and so harnessing the wind was seen as an important component of this policy initiative. A decade of research saw a Danish designemerge as the industry standard: the three-bladed, horizontal axis, upwind machine. A modern wind turbine comprises a tubular ...

  • The Sol of Cuba

    I went to Cuba with Global Exchange, a non-profit organization that organizes “reality tours” of Cuba. The tour coincided with an international solar energy conference organized by CubaSolar, a nongovernmental Cuban organization. Having worked on numerous solar energy projects in Central America, I went to Cuba with the misconception that I could use my renewable energy technology transfer skills ...
