SEADOG - Pump Technology Harvests Renewable Power From Ocean Waves

SEADOG is a "point absorbing" wave energy converter designed to extract a small amount of energy from a portion of the wave front as the wave passes by, as opposed to other wave energy designs that attempt to extract large amounts of energy but may terminate the wave in the process.

The Hydrogen Economy And Fuel Cells

Fuel cells will be one of the key components in the hydrogen economy. They will replace the internal combustion engine and will convert the future main store of energy (hydrogen) to power when it is needed.

The Numbers Don't Add Up?

A teenager should never have to plead for help from their elders. All of these concerns should be taken care of already, and taken into serious consideration. Workings towards a successful solution should be our number one priority, but it's not ... we're obviously not living in a perfect world... but don't you want to strive to get as close as you can get?

The Value Of Energy Efficiency In Stand Alone PV Systems: A Simple Approach

We know that conservation is important, but exactly how many dollars should be invested to save a KWH? We answer this question by comparing the investment necessary to produce one KWH/day with the cost of conserving one KWH/day. Even though a KWH is relatively expensive, with effective investments in conservation you can substantially reduce the total cost of operating a home with a stand alone power system.

Zinc Air and Nickel Zinc Hybrid Vehicle

The idea of metal fuels as an energy source has existed for over 100 years. Many companies have attempted to develop and commercialize zinc air fuel cells and nickel zinc batteries but were unable to solve the problem of dendrite formation.

Coffee Jar Syphon Pump

I used a coffer jar pump of 7 chambers to pump water about 6 ft high into a 50 gallon barrel to water my garden.

Live Safer (And Better ) With Solar- Using The Sun For Emergency Preparedness

Solar links the ways of the past with technologies of today to help make life on our planet easier and more secure.

PDA Energy Auditing Choices

Choosing the right hardware is among the most important decisions that you will make when beginning an energy audit / inspection application.

Radiant Comfort And Energy-Efficiency

The concept of radiant heating is to warm walls, objects, and people which in return warm the air creating ultimate comfort at lower room temperature.

Real Costs Of Fossil Fuels

We can lower our healthcare costs, reduce our air, water and thermal pollution, develop a more stable economy and become a far more secure nation if we just begin this inevitable process of evolution toward renewable energy sources.

Shkoodaow - An Earth Wise Fire Log

CANMET tests have shown that this renewable biomass fuel log produces 94% less CO and 84% less Particulate Matter emissions than cordwood.

The Blackout Of 2003

In the long term we need to move toward a distributed/decentralized power generation network.

The Thermo Acoustic Engine

Thermoacoustic experimenters have known for about ten years that as a stack (like the stainless wool) in a tube is heated at one end, it begins to sing because of the temperature gradient (hot to cold).

A Few Free Energy Devices that Work

A 7 year study of "free energy" devices, sometimes called "over unity" devices, was done to determine if any of these devices generated power by transferring energy from unknown sources and if so to determine where the energy was coming from.

Safer Backup Power With Solar - Using The Sun For Emergency Preparedness

With a little thought and preparation, you can solve many of your electrical needs safely in the event of an extended power outage. The do-it-yourselfer might want to make their own portable solar power supply, or put a 12 volt motor in a small swamp cooler to solve those electrical needs.
