Technology Review: Lithium-Ion Electric Car - 0 views

  • Light and compact lithium-ion batteries sound great for electric vehicles--aside from their historical tendency to catch fire. But recent advances in electrode chemistry have made them much safer. One of the first vehicles to use the new batteries comes from a Norwegian company, Think. By year's end, Think plans to start selling ultracompact electric cars with a range of more than 100 miles. A123 Systems of Watertown, MA, and Indianapolis's EnerDel will provide the batteries.

IEEE Spectrum: How Much Water Does It Take to Make Electricity? - 0 views

  • Remember when you were a kid and your parents made a big fuss about turning off the light when you left a room? Who knew that, besides adding to the monthly electric bill, keeping a single 60-watt lightbulb lit for 12 hours uses as much as 60 liters of water? According to researchers at the Virginia Water Resources Research Center, in Blacksburg, Va., fossil-fuel-fired thermoelectric power plants consume more than 500 billion L of fresh water per day in the United States alone.

Hydrogen fuel cells power Fujitsu data center | CNET News.com - 0 views

  •  
    Hydrogen is a better source of energy than you think, according to Fujitsu. The Japanese electronics giant inaugurated a 200-kilowatt hydrogen fuel cell from UTC on Friday that will provide electricity as well as heat to the buildings on its campus here. The fuel cell--which sits in the parking lot and looks like a pair of giant green dumpsters--provides two types of energy to the facility. First, a unit heats methane with steam to create hydrogen. The hydrogen is passed through a proton exchange membrane (PEM). The electricity produced by the reaction with the PEM runs lights, computers and other equipment

Economic viability of small to medium-sized reactors deployed in future European energy... - 2 views

  • Future plans for energy production in the European Union as well as other locations call for a high penetration of renewable technologies (20% by 2020, and higher after 2020). The remaining energy requirements will be met by fossil fuels and nuclear energy. Smaller, less-capital intensive nuclear reactors are emerging as an alternative to fossil fuel and large nuclear systems. Approximately 50 small (<300 MWe) to medium-sized (<700 MWe) reactors (SMRs) concepts are being pursued for use in electricity and cogeneration (combined heat and power) markets. However, many of the SMRs are at the early design stage and full data needed for economic analysis or market assessment is not yet available. Therefore, the purpose of this study is to develop “target cost” estimates for reactors deployed in a range of competitive market situations (electricity prices ranging from 45–150 €/MWh). Parametric analysis was used to develop a cost breakdown for reactors that can compete against future natural gas and coal (with/without carbon capture) and large nuclear systems. Sensitivity analysis was performed to understand the impacts on competitiveness from key cost variables. This study suggests that SMRs may effectively compete in future electricity markets if their capital costs are controlled, favorable financing is obtained, and reactor capacity factors match those of current light water reactors. This methodology can be extended to cogeneration markets supporting a range of process heat applications.

The "Energy Plus" Building Produces All Its Own Power : MetaEfficient - 0 views

  • The “Energy Plus” office building, to be located outside of Paris, is designed to produce all its own energy for heating, lighting and air conditioning. This zero-energy building, according to the designers, will be the greenest office building ever created. It will accomplish this by having more solar panels on its roof than any other building - producing enough energy to power the entire building and still feed extra back into the grid.

ScienceDirect - Energy Conversion and Management : Evaluation of small wind turbines in... - 0 views

  • The island of Barbados is 99% dependent on fossil fuel imports to satisfy its energy needs, which is unsustainable. This study proposes a 10 MW distributed wind energy scheme using micro wind turbines (WT) of horizontal (HAWT) and vertical axis (VAWT) configurations. These units are rated less than 500 W, and the scheme is hereafter referred to as mWT10. mWT10 is compared to the proposed 10 MW medium WT farm by the Barbados Light & Power Company (BL&P). The economic bottom line is the levelized cost of electricity (LCOE). The results highlight the BL&P proposal as the best economic option at BDS$0.19 per kWh, while that of both mWT10 configurations exceeds the conventional cost of BDS$0.25 by two to nine times. This is attributed to significantly higher relative installation and operational costs. However, the financial gap between mWT10 LCOE and the retail price of electricity is much smaller due to a large fuel surcharge passed on to each customer. Annual additional benefits of using wind energy include: greenhouse gas emissions savings of 6–23 kt of carbon dioxide; and anavoided fuel costs of BDS$1.5–5.3 million.

Peak Energy: Green Buildings In Madrid - 0 views

  •  
    Herzog and de Meuron have been very busy lately designing some amazing new buildings in Europe, like their Project Triangle in Paris. Their newest design for the Spanish banking group BBVA will be built on the outskirts of Madrid as early as 2013. The verdant green headquarters will feature luscious gardens and will create it's own microclimate by using natural ventilation, evapotranspiration, and the shade of the gardens and buildings to create a cool artificial oasis on a desert-like site. The project is meant to function as a small city, encouraging people to walk and meet within the outdoor spaces. The project is essentially a linear series of 3-story buildings seperated by alleyways and irrigated gardens. The smaller buildings are designed to give employees access to natural light and the outdoors, while the tower rises as a skyward-tilted circle, giving BBVA a presence in the Madrid skyline. The courtyard located around the tower is planted with shady trees and features a large basin of water that serves as a resevoir and humidifies the air.

  •  
    Wind power has long been the big beast of the renewable energy jungle. The technology to generate electricity from wind has been established for more than two decades, and in the past five years has been refined and expanded towards much larger and more powerful turbines including ones that can be used at sea, and towards very small turbines that can be fixed to office buildings or houses.

Scaling small energy harvesters for the grid - 2 views

  • there are now other forms of energy harvesters developed initially at the micro level which are now being scaled to produce enough energy to replace or supplement grid power. For example, take the humble bicycle dynamo - based on an electrodynamic energy harvester. The same technology is also used in large scale wind power, but now it has been redesigned to work beyond a rotary means. EnOcean, Germany, offer more than 500 products based on this technology from light switches powered by pressing the switch to wirelessly monitored mouse traps powered by the mouse entering the trap. Re designing the decades old technology is now making other, larger scale applications possible.

Flat Panel Technology Boosts Solar Efficiency - 0 views

  • Xtreme Energetics has investigated the possibility of using mechanical trackers to perform the same light-focusing duties as other solar array manufacturers have. However, HP’s transparent transistor can do the job electronically, rather than mechanically, and significantly reduce the costs of such an installation. Such a solar array is known as a concentrating photovoltaic (or CPV) solar array. To date, CPV arrays are fairly expensive and cannot store energy, making them less useful. They also work best in specific sections of the world — those with the highest levels of solar radiation, such as the southwest United States and northern Africa.
