NWUAV MEMS Fuel Injection System

CurtisEllzey — Thu, 29 Oct 2009 13:45:00 GMT
The NWUAV MEMS Fuel Injection System uses Hewlett Packard Ink Jet technology to atomize a variety of fuels including JP5, JP8 and logistical fuels used in internal combustion engines. The system will allow longer duration flight times and reduced (green house gas) emissions as a result of the ability to digitally control the fuel delivery and droplet size to a level much smaller than is conventionally possible using carburetors and COTS (Commercial Off The Shelf) fuel injectors. For more information, visit NWUAV Propulsion Systems.

Westech Solar Integrative Controller

CurtisEllzey — Wed, 28 Oct 2009 11:50:00 GMT
The operation of a Westech solar collector is as follows: Solar radiation is absorbed by the evacuated tubes and converted into heat. Heat pipes conduct the heat from within the solar tube up to the header. Water is circulated through the header via intermittent pump cycling. Each time it circulates the temperature is raised by 9-18° F and throughout the day the water in the storage tank is gradually heated. The system operates automatically by using Westech's intelligent controller, detailed here. For more information, visit WesTech Solar.

Westech Solar Collector Systems

CurtisEllzey — Tue, 27 Oct 2009 13:20:00 GMT
The Westech Evacuated Tube Solar Collector is a device that absorbs thermal energy from the sun and converts it into usable heat. The heat is normally absorbed by water, or a freeze resistant water mix, which can then be used to supplement hot water heating, space heating and even space cooling via use of an absorption chiller or desiccant cooler technology. For more information, visit WesTech Solar.

Westech Evacuated Tube Solar Collector

CurtisEllzey — Mon, 26 Oct 2009 12:02:00 GMT
If you’ve ever used a glass lined thermos, you know that a vacuum is an excellent insulator. Evacuated tubes absorb solar energy and convert it into heat for use in water heating. The insulation properties are such that while the inside of the tube may be up to 300° F, the outer surface is cold to the touch. This means that evacuated tube water heaters can perform well even in cold weather when flat panel collectors suffer from heat loss. For more information, visit WesTech Solar.

Solar Decathlon Refract House - Part 2

CurtisEllzey — Tue, 29 Sep 2009 13:22:00 GMT
We continue our interview with Preet Anand about the Refract House, which uses a holistic and environmentally conscious design to produce a contemporary architectural solution using highly efficient and sustainable systems and materials. The U.S. Department of Energy Solar Decathlon 2009 combines the latest in home design and energy performance with the innovative spirit of university students from around the world. In the fall of 2009, the teams will transport their homes to the National Mall in Washington, D.C., forming a "solar village", where they will be judged in 10 different categories or challenges. Also watch this episode: Solar Decathlon Refract House - Part 1. For more information, visit Refract House.

Solar Decathlon Refract House - Part 1

CurtisEllzey — Mon, 28 Sep 2009 12:05:00 GMT
For three weeks in October 2009, the U.S. Department of Energy will host the Solar Decathlon—a competition in which 20 teams of college and university students compete to design, build, and operate the most attractive, effective, and energy-efficient solar-powered house. Engineering TV talks with Santa Clara University's Preet Anand about the Refract House, made in conjunction with California College of the Arts. The Refract House uses the latest in sustainable, bio-based building materials, cutting-edge thermal efficiencies, and comprehensive controls systems. Also watch this episode: Solar Decathlon Refract House - Part 2. For more information, visit Refract House.

SolarMagic Power Optimizer

CurtisEllzey — Tue, 08 Sep 2009 14:32:00 GMT
When it comes to solar energy, the power of the solar array is only as strong as the weakest-performing panel. And in real-world conditions, where shade is common from sources like trees, chimneys, power lines and even bird droppings, solar efficiency can be decreased significantly. In fact, as little as 10% shade on an array can result in as much as 50% lost energy. SolarMagic power optimizers maximize the energy potential of each individual panel so as much as 50% of the lost energy can be reclaimed. For more information, visit SolarMagic.

Drake Landing Solar Community

Terry Knight — Thu, 13 Aug 2009 09:00:00 GMT
The Drake Landing Solar Community is a 52-home subdivision that uses the sun's energy to supply 90% of space heating and up to 70% of domestic hot water needs. The system uses 800 commercial solar collectors in conjunction with seasonal storage to store the sun's energy during the summer, and distribute heat to the homes in winter as needed. A two-collector residential solar water-heating appliance from EnerWorks is installed on each home to provide solar hot water year-round. Also watch this episode: EnerWorks Solar Water Heating. For more information, go to: EnerWorks.

EnerWorks Solar Water Heating

CurtisEllzey — Mon, 10 Aug 2009 09:00:00 GMT
In a typical household, water heating accounts for 25% of the energy used and produces an average of two tons of green house gas emissions annually. With the EnerWorks residential solar water heating appliances, renewable energy from the sun is used to heat your water instead, providing a clean, cost-effective residential solution. Rob Singlehurst from EnerWorks shows us how the technology works and discusses the differences between the direct and indirect systems. Also watch this episode: Solar Water Heating Efficiency.
