stationary engine thermal power station hybrid and alternative fuels with the piston charger engine
Posted by Admin in Alternate Fuels on May 30th, 2010
a piston charger is charging one or more working cylinders
and simultaneously regulating the inlet and outlet aperture
leading to no loss of air and fuel in the exhaust.in the main
cylinder combustion takes place every turn,lubrication like a
four stroke,compact,high torque,power,less fuel consumpt.

What would you need to do to a brushless DC motor to turn it into a generator?
Posted by Admin in Homemade Windmills on May 29th, 2010
I am new to learning about generators and dont know much about DC electricity. I am experimenting with building a windmill for household power. Would machining the shaft and placing magnets in it work? I am first building one with homemade coils and earth magnets, but somebody suggested using a dc motor housing and thought i would check into it. Thanks for any input.
Hi,
First of all,a brushless DC motor needs an alternative arrangement that could cause the reversal of input direct current for developing a constant torque in armature.This may be achieved with the help of any electronic inverter connected to the input terminals of motor as the brushes in a dc motor actually act as mechanical inverter.
Now,to run a dc motor as generator:
Rotate the shaft of the motor by coupling it through any prime mover(such as engine or any other generator) at rated speed
The field excitation to the motor circuit must be provided using any dc source.Now,the motor runs as a generator.
Importantly,an arrangement(either an electronic rectifier or brushes) that could reverse the direction of induced current in the armature,which is of alternating nature,must be provided at the output.This is required so as to obtain dc power at load.
I want to go solar… all electric or keep gas?
Posted by Admin in HomeMade Solar Panels on May 27th, 2010
Im considering a few things and would appreciate any input. I would like to start installing solar panels over the next few years as well as a homemade VAWT windmill (not too big) and black tubing to heat up water before it gets to my water tank.
1 – Install a tankless water heater. Do I go gas or electric?
2 – Install electric clothes dryer instead of gas?
3 – electric stove instead of gas?
My thinking is to go all electric and get rid of my gas bill entirely and try to generate enough electricity on my own to power all the electric appliances.
Just not sure what direction to take! I dont use much electricity ($20/mo) and my gas bill is $10 in the summer and up to $40 in the winter from cooking and heating. Ahhhh. I forgot about heating. It doesnt get too cold where I am, but I would still need heating. I would think gas is still cheaper then electricity for heating.
Any tips or ideas out there? Thanks!
I can see advantages to both options. It all depends on your intentions for going solar. Is your motivation environmental, independent living, or emergency preparedness? Do you intend to keep your utility connection and supplement it as much as possible with solar, or do you wish to be utility independent? If you keep the utility connection, then go all electric, and buy some Eden-Pure heaters for your heating needs. You will feed the grid all summer long, build up a big credit, and use the excess to run the heaters in the winter. If Independence is your goal, gas makes a good back-up plan in the event your solar does not generate a sufficient amount of power. When you say "gas" are you talking kerosene, LPG (propane) or natural gas? If you want to prepared for all emergencies, and LPG is available in your area, use it. Buy a tank big enough for a year’s supply.
Be careful of tankless water heaters–gas or electric. Many do not support preheated water conditions, and will cause problems on a solar water heated system. Your bills are quite low, you are likely very energy conscious already. Solar will be a great fit for you regardless of which way you go.

How to Make Solar Panels – Build Homemade Solar Panels & Save $1000s

http://www.SolarEnergyGuide.net – How to Make Solar Panels – Build homemade solar panels & Save $1000s
Building homemade solar panels is an excellent way to save money and protect the environment at the same time. Making your own solar panels is not as difficult as it may sound. Some of the things you will need are: an electric stove, copper wires, a micro-meter etc. These materials can be easily found in any hardware store. To build your own solar panels you will need to make solar cells, connect them in series and also connect the solar panels to one another. After that you should connect the solar panels to a battery and an inverter that will convert the solar energy into usable form for home use. It may take you a few days to complete the project, but it is definitely much better to do it yourself instead of paying up to $3000 for a ready made solar panel.
This is why you should use the power of the sun: * Save more than 80% on your electricity bill or even eliminate it completely. * Save on taxes for using green energy. * Gain money by selling the extra power to the electric company. * Reduce the pollution by using a clean and inexhaustible energy source.
The best place to install solar panels is your roof because there they can absorb direct sunlight, but if that is not an option you can also use your garden, your backyard and many other places. Solar cells collect energy even in cloudy days.
Solar energy systems can be used to produce electricity to power all devices in your home (photovoltaic) or to produce heat for bathing and your swimming pool (solar thermal system).
In general building your own solar power system costs less than $300 and practically pays for itself within a couple of months.
More and more people everyday take advantage of the power of the sun and save lots of money on electricity bills.
By following the step-by-step instructions of a Reliable Solar Energy Kit you can follow their example and protect the environment. Read this DIY Solar Kits Review and find the manual that best fits your needs. How to Make Solar Panels – Build Homemade Solar Panels & Save $1000s
