Well, another power outage caused me to get inventive. Thankfully I have battery operated hand drills all over the place. I took an old table fan that was going bad, making noise, and converted it into a windmill.

Above in the photo you can see it sitting outside. I simply opened up the fan, drilled some holes in the armature, inserted magnets and put it all back together. Now it is charging batteries in the wind for free.

Table Fan Windmill

On Thursday last week, we got hit with a terrible snow storm. It dumped 3 feet of snow during the day and brought down trees. These hit power lines and cable lines. I lost power. That took out my water, light and heat. My car was under 3 feet of snow, so there was no running for supplies.

I had to improvise, so I took out some vegetable oil, a glass container and some twine. I made an oil lamp for light and heat.

The diy oil lamp worked surprisingly well. It helped warm up the place a bit and provided quite a bit of light. I made two of them and one had a double wick for more heat and light. The only thing I had to do was top off the oil once a day to prevent smoking. When the oil got a bit low, the wick was too long, making smoke. So, I just kept it full. The thing only burnt about a quarter to half inch of oil per 24 hours. That was a nice bonus. It is very efficient.

I posted all the details here:

DIY Oil Lamp

I just moved to the country!

Now I can put my solar panels outside in the full sunlight and really begin testing. I had to have them in my sliding glass doors because my landlord would not allow me to put them outside anywhere.

Well, now I have an apartment on 1.5 acres of free, wild land in the mountains. When I get a warmer day, the panels are going outside in the full sun. I will set up sunlight tracking systems for maximum energy output during the daylight hours.

I was only getting some light directly on the panels during the mid day in my old place. This provided enough energy to power a couple energy efficient lights and my netbook in the evenings.

With solar tracking, I should get about 870 watt hours of energy during the ten hour long winter days and up to 1300 watts during the summer months.

I have an idea to increase the energy output even more. If you look up "Bedini Motor" or "SSG" on the internet, you will find a sort of "free" energy generator. It takes a small amount of energy to run it and puts out larger amounts of energy into batteries. I have been experimenting with this idea for a few years now and may try using solar energy to power the Bedini motor, which will charge batteries.

Above is a picture of a roller skate wheel generating electricity using the Bedini concept.

I have a home made LED lamp now as my main source of light in the living room. I designed it to fit a normal light bulb socket. It is running off my solar battery pack through an inverter.

The great thing about this LED bulb is that there are no resistors used at all. That means no waste energy. I used 60 LEDs, a bridge rectifier and a capacitor. All energy is used for light output. Most LED bulbs you can buy in stores use a resistor for every LED to reduce the amount of current. I just divided the amount of current with LEDs themselves.

You can see details on how to make one at:

The total power consumption for this lamp is about 4 watts.

My solar panel is putting out more energy than my batteries can hold on a sunny day. I had to add more batteries to increase the capacity. That also means more possible energy use for me at night.

I now have five 10 Amp Hour batteries hooked up. That equals about 600 watts of total energy capacity. Theoretically, I could run my netbook for 15 hours on a full charge. Of course, it is winter now and the sun doesnt shine all the time so I will never reach that capacity. But in the summer, I will probably have more energy than I could use.

My living room light and my aquarium are now running full time on solar energy.

Today was very dark outside. Almost no natural light today. The solar panels did not really produce any energy at all. And I was home all day, using my netbook on solar. Had to use a light most of the time too.

The batteries are running at about 12.05 volts at 6:pm already. Not good. I may need to add more batteries in order to have more reserve energy for cloudy days.

Finally got my solar panel up and running. The toughest part was figuring out where to put it because my landlord will not allow me to put it anywhere visible. So, it is now in my sliding glass doors, facing the south side. It catches sun from about 8am to 5pm. It is not the most efficient setup, but it works well enough.

I have a $30 solar charge controller from ebay that can handle 15 amps of power. I am using a Belkin 50 watt inverter from eCost.com to convert the power to 120 volts. And there are 4 sealed lead acid batteries that I got for free, totaling about 40 amp hours together. I use a special radiant energy battery charger to restore old, discarded batteries to like new condition. See Radiant Charger for details.

The solar panels generate some energy to charge the batteries even on a dark, cloudy day. That was a surprise.

Right now my aquarium filter is running off the solar energy full time and I have enough reserve energy to run a 9 watt (60watt equivalent) energy efficient light bulb at night for hours. My netbook only needs 40 watts to power, so that runs nicely as well.

Testing my finished solar panels.

Above you can see my new solar panels putting out some nice power in the late afternoon winter sun. The volt meter reads 17.81 volts.

I also put an old 1.5 watt solar panel in my bedroom window to charge a small sealed lead acid battery during the day. At night it powers a 12 volt fluorescent lamp I got from Target for about $6. Free light for reading.

I finally got all the materials together for my solar panel. Plexiglas at Home Depot was the most expensive single part, at $12 for a plate. I needed two of them. Also got some wood trim at only 98 cents a piece to use for the framing of the panel.

Plywood at Home Depot, precut is only about $5 each. I need two of everything because my panel will be too large otherwise. I will make two identical panels, each putting out 9 Volts.

In the above pictures, I got all my tools ready and started soldering - finally. I had to use a weight to hold the solar cell in place and another weight to hold the tabbing wire down while I soldered it into place.

Hopefully I will have this project finished soon.

I finally got some time on my hands and started soldering my new solar panels myself. I laid them out on a table to find the best configuration for the cells. I will have to make two panels, each with 18 cells in order to make up the correct voltage and wattage. I will take pictures later and upload them.

Anyway, I cut the wood and started soldering the tabs on the cells. Then I started to solder the cells together in series to add up the voltage. They are each 0.5 volts. 36 cells will make up 18 volts, which is the correct voltage for a solar panel to charge 12 volt lead acid batteries. I am making two panels of 18 cells instead of one large one so that they wont be too large. Each panel will be about 18 inches by 22 inches.

More details and pictures later.

I have discovered that prices have more than doubled in the last years on solar panels. I may have to modify my prices here. Years ago I was able to purchase solar panels for about $2 per watt. Now you are lucky to find them at $3-4 per watt. Most of them are around $5 per watt.

Therefore, I bought 50 solar cells from Ebay for only $99. I had to buy the flat connecting wire separately, bringing my total to $120 for about 87 watts of power at 12 volts. I am now in the very slow process of assembling my solar panels. I will make two panels in order to keep the size down a bit. The panels will be about 22 inches square each. Below is the picture of my cells.

This is the picture taken from Evergreens site on Ebay. Each cell measures 3x6 inches. The are extremely fragile and thin though, so this is taking a bit more time than I had originally planned. One cell puts out 0.5 volt at 3.5 Amps. This equals 1.75 Watt per cell. You need 36 cells to get 18 volts at 63 Watts. If you were to purchase the panel ready made, it would run you about $300 for this size.

Actually, for this test, I wanted to run 18 watts, which cost about $100 for a ready made panel.
