WHY 2 BLADED ROTORS MAKE SENSE

One of the greatest advantages of two bladed rotors is the cost savings realized by the elimination of a blade. Although it can be argued that a teetering hub is more complex and costly than the rigid hub of a three bladed rotor, technological advances have reduced this complexity and cost. For example elastomeric bearings for the teeter hinge have eliminated the need for ball or roller bearings and the maintenance associated with these components.

The term micro grid is mentioned more and more in publications on distributed generation. It generally means a collection of consumers, generators and potential energy storage entities connected together and operated as a small grid which is connected to the main grid, but capable of operating a self-sufficient island. The micro grid is typically linked to the grid with the help of a switch, which allows it to work both in grid-connected as well as island mode. However, island operation is not currently permitted in the majority of countries.

BIOMASS PYROLYSIS

Pyrolysis is the thermal decomposition of biomass occurring in the absence of oxygen. It is the fundamental chemical reaction that is the precursor of both the combustion and gasification processes and occurs naturally in the first two seconds. The products of biomass pyrolysis include biochar, bio-oil and gases including methane, hydrogen, carbon monoxide, and carbon dioxide. Depending on the thermal environment and the final temperature, pyrolysis will yield mainly biochar at low temperatures, less than 450 0C, when the heating rate is quite slow, and mainly gases at high temperatures, greater than 800 0C, with rapid heating rates. At an intermediate temperature and under relatively high heating rates, the main product is bio-oil.

JATROPHA FOR BIOFUELS

Does Jatropha risk a backlash from public opinion? Jatropha proponents have justifiably been promoting its benefits as a sustainable source of oil crops for years, but from the agro-business side it seems to be evolving in the opposite way: monoculture, hurting biodiversity, causing deforestation and competing for land with food crops.

Solar Heating,Cooling & Refrigeration - Using The Sun For Emergency Preparedness

It is not fun being without air conditioning in the summer. Several years ago we had our house unit go out on the hottest day of the year. It was 126 degrees F in the shade and even hotter in the house. Fish were dying and we were miserable. After searching for two days I finally found a window swamp cooler that got us by until we could get the house air conditioner fixed.

Lighting The Way To Energy Efficiency - And Cost Savings- With Whole-Home Lighting Controls

It's not often we associate something that consumes power-such as lighting-as a means to saving or conserving, but by their inherent design and very purpose, lighting controls are a way to not only save electricity and related costs, they're a fun, convenient and futuristic way to go about it.

Wind-Diesel Systems

Making a hybrid power system work in the long run is not just about buying and installing the equipment. Like with any other technical system, there must be adequate documentation of the installation. Operators and maintenance personnel must have proper training. Funds must be allocated for maintenance and repair, e.g. to replace a worn-out battery bank or hire a specialist for troubleshooting.

Advantages of Electric Automobiles

The automobile manufacturers claim that very few people (apparently less than 1000 people in the USA) are willing to buy electric automobiles. However, I know many of us would like to "refuel" our cars by plugging them into an electric outlet at home. If we work together by educating the public, the news media, and the automobile manufacturers, we can make production volume electric automobiles and Grid Rechargeable (plug-in) electric-biodiesel hybrid automobiles a reality.

Make Your Next Science Fair Project Green

One excellent idea is to create a miniature "hybrid" renewable energy power plant. This could be accomplished by combining solar cells and a small windmill kit. Such an idea could graphically demonstrate the complementary nature of these two free power sources.

Safer Cooking With Solar - Using The Sun For Emergency Preparedness

I use my Global Sun Oven to cook anything that I would normally cook in my regular oven. My family loves fresh-ground wheat bread and we regularly cook roasts, cookies, rice, casseroles, baked potatoes, cakes and more. I can't tell you how many times I've been told that sun cooked chicken tastes better than Kenny Rogers' rotisserie chicken (and I love K.R. chicken).

HVAC Zoning Controls

Homeowners would like to increase their comfort level while conserving energy. An excellent method to do this is through zoning. Most two-story homes have an 8 to 10 degree temperature difference between upstairs and downstairs (because heat rises). Additionally, larger ranch homes generally have a big temperature difference between one end of the house and the other (due to the distance of the duct runs).

Using Solar Energy In California

The main impetus for the accelerated interest in solar electricity has been the California Energy Commission's rebate program. They offer rebates of $4.00 per watt for homes and $4.50 per watt for businesses (approximately 50% of the total installed cost of solar electric systems).

How I Get My Hot Water Fast

Electricity savings for a household of four occupants varied from about 200 kW-h/year to 400 kW-h/year for a single point of use. Extrapolation to a home with at least four points of use would imply electricity savings from 800 kW-h/year to 1600 kW-h/year.

Watts Up!

A commercial business owner in Southern CA, utilizing several stores in a strip mall, is currently paying $2,500.00 per month for electricity. He/she is being warned of a 78% increase by 2002, which would put his/her costs at $4,450.00 per month. This considerable increase in overhead will spawn a definite increase in his/her products and services to customers. In order to remain competitive, a business owner will be forced to find solutions to save energy on a long term basis.

The Residential Gateway As Energy Manager

In a survey of high-end entertainment households, when asked about the usefulness and interest of PC-based control services, respondents ranked energy management as the most attractive service option with 54% indicating that they had a strong interest in such a service. Utilities are aware and energized by this new demand, and as telemetry services become more widely available, Parks Associates believes consumers will be receptive to such services.

Can Home Automation Save You Money On Your Electrical Bill?

Ideally, a home energy controller would be programmed to calculate when loads should be turned on or off. It should also be designed to look at alternate solutions such as closing the window blinds before turning on the air conditioner to cool a room. The controller has to strike a balance between energy savings and comfort and convenience to the homeowner. The system should be almost invisible to the homeowner. If it isn't, it will soon be disabled.

Managing Energy Usage Among Residential Customers

The EMi thermostat is connected to an external modem that accesses the Internet via the regular telephone supply of a home or small business customer. When the utility company wishes to initiate a supply curtailment, it sends a call to the modem using a distinctive ring pattern that will activate the modem. The modem then calls a central utility curtailment dispatch station, from where it downloads the new settings to the thermostat.

Automated Window Shading

As compared with passive switchable glazing technologies such as photochromic or thermochromic -- which merely react to environmental conditions such as ultraviolet radiation or temperature -- SPD technology offers the user control over the amount of light transmission and much faster switching speeds.

Automating HVAC Registers

To make the motorized registers, I'm using standard units purchased at a local hardware superstore, and the small servo motors were purchased from a local hobby shop that deals in Remote Control cars, planes and boats. All that's needed is a simple circuit to control them.
