Photovoltaics are cleaner, more flexible, much faster to install, safer, more secure and create far more jobs than all competing forms of fossil fuel energy generation.
Consumers are already well familiar with the benefits that Lithium-ion batteries, yet they are now becoming more familiar with the drawbacks. They'll soon discover the value in terms of both safety and performance that Saphion Lithium-ion technology can bring to the businesses and industries that serve them.
Solar Data Centers is the first company in the world to employ solar energy to run every aspect of an organization's Internet operations.
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.
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!
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?
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.
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.
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 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.
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.
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?
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.
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.
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.

The IMO FireRaptor provides three forms of Solar Panel Rapid Shutdown to ZERO VOLTS in case of fire or other emergency: Manual Panel Shutdown to 0V Operated from Ground Level, Automatic Panel Shutdown to 0V at >85°C (185°F) Temperature, and an automatic Panel Shutdown to 0V on External Power Loss. The FireRaptor can be installed without any set-up and with any string inverter as its functionality is completely independent. "Plug & Play" style installation using industry standard connectors is easy, whether fitted to new installs or retrofitted to existing projects to upgrade fire safety functionality. Meeting NEC2017's regulation to switch DC current at the PV panel in under 30 seconds, FireRaptor is remains one of the safest and most effective means of isolating DC current at the source, and the only rapid shutdown with a 20 year warranty.
