ULTRACAPACITORS AND THE HYBRID ELECTRIC VEHICLE
Compact in size, ultracapacitors can store an incomparably higher amount of energy than conventional capacitors. Indeed, ultracapacitors are currently available on the market with capacitance ranges up to 2700 Farads, and they can release that energy at both a high or a low rate.
Advantages Of Electric Cars And Plug-In Electric-Biodiesel Cars
If the vehicle is a Grid Rechargeable (plug-in) capable hybrid electric-biodiesel (or diesel or gasoline) automobile, the car has all of electric automobile advantages for short trips plus the range & fast refueling advantages of internal combustion engine automobiles!
Beginner's Guide To Solar And Wind Energy
The question is why are you interested in using solar or wind energy? Is it because you need some back-up electricity for when the utility grid is unavailable? Or is it because you want to spend less money per month on electricity?
Can Electricity Become A Fixed Cost?
The present commodity nature of electricity is being replaced by a decentralized model where homeowners can supply their own power using their own equipment. This changes the variable and volatile cost of electricity in a "fixed" cost which never goes up.
Making Solar Electric Systems PAY BACK FAST
You are an excellent candidate for a solar electric system if your electric bill is over $75 per month, you pay more than $0.12 per kwh for electricity, your state offers substantial rebates for solar electric systems, and you have good solar exposure.
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.
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.
