  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Peak Oil – Peak Opportunity?

    Possibility and public policies can harness renewable energy technologies for a bright future “Alternative” fuels are nothing new. In fact, they were the mainstream power source a century ago. Rudolph Diesel built his engine to run on peanut oil. Henry Ford designed the Model T to run on ethanol. Wind delivered a significant source of power in the last century. Cheap gasoline (and ...

  • Adoption hurdles and challenges with small wind turbines

    Adoption Hurdles and Challenges with Small Wind Turbines Wind energy is very promising. It can be harvested without any costs, and like solar panels, wind turbines are environmentally-friendly. However, such machines are not living up to their potential. Some users have reported low efficiency rates, unpredictable performance and costly adoption barriers. ...

  • How is biodiesel produced?

    This article is the first in a series that will take a close look at alternative fuels production and source materials. Over the next several months, we will cover natural gas, propane, ethanol, hydrogen, and fuel cells. This month, we will focus on biodiesel. Methods for creating fuels from renewable biomass feedstocks have been used since the 1800s. Vegetable oils were used in diesel engines ...

  • Integrating Solar Lights with Motion Sensors

    Solar powered motion sensor lights are effective security accessories for remote locations that experience sufficient amounts of sunlight throughout the day. The units offer seamless installation, require minimal maintenance and remain operational without electrical support. Locations without dependable access to the grid may find solar security lights useful in maintaining illumination at night. ...

  • Generating biomass fuel from disaster debris

    Natural disasters create massive amounts of vegetative debris, the majority of which is landfilled or open burned. These environmentally harmful practices are the norm partly out of necessity and convenience, with a focus on clearing material as quickly as possible after a disaster - versus finding outlets for the material including mulch, compost and biomass fuel. The biomass fuel market in ...
