This solar boat is used mostly on lakes. Under good sunshine the boat can be powered totally by solar energy and it can be driven by humans when sunlight is insufficient. The advantage of the solar boat is absence of batteries.

The 123 watt Polycrystalline Solar Kit with Sharp® Module is the ideal solution for back-up and remote power use, as well as use for RV's, homes, boats, 12 Volt battery charging and solar power stations, lighting equipment, and more! The panel has high efficiency Polycrystalline solar cells, and is completely weatherproof. You can always connect multiple panels for more power! Complete kit includes: wiring, brackets, screws, and voltage tester.

Solar Powered Suncat Batteries

Our sun, a nuclear fusion source which is already working reliably for more than 5 billion years, produces an extreme amount of energy. Within 6 hours, deserts on Earth receive more solar energy than we use in a whole year globally. Therefore it is strange that we are not already using this free energy source to it’s full potential. It looks like this is going to change now. A group of twenty big German corporations has plans to deliver solar power from Africa to German households in Europe within 10 years. The plan consists of investing 400 billion euros to build gigantic large Concentrated Solar Power (CSP) plants in North-Africa. With this investment, 15% of the total European electricity can be generated by solar power day and night. It is one of the biggest private green initiatives.

Solar Power

I've loved solar as a green energy source since I was in elementary school. Actually, I'll tell you a little story related to that. When I was in fifth grade, my parents bought me a toy solar car that I quickly assembled. The car was interesting and all, but it was really just some cardboard, a solar panel, and a few other electrical parts. In short, a solar car wasn't very interesting to me. It was the summer and I was feeling very hot. I got my mind to thinking and decided that what a person would want more than a solar car was... a solar fan! By definition, when you are outside and it is hot, the sun is probably shining brightly. I looked around the house and found one of those little handheld fans powered by batteries and simply hooked the solar panel from the toy car up to the batteries and I had a solar fan! I took the fan with me everywhere that summer, and I was proud that I had created something!
Now onto solar... the real issue many people seem to have with it is the cost. It costs about $20,000 to outfit a house with solar panels. This is a daunting price, but obviously the cost depends on the size of your home. The price per watt installed is about $10 to $12. However, while the price appears daunting, many of these solar home additions pay for themselves in a few years. If you are interested in learning more about the price of applying solar to your home in different ways.

Another issue many people struggle with is the look. Having your roof covered in solar panels is not an appealing prospect to some, though I would argue that if you do follow through and add solar panels to your house the good thing is everybody in your neighborhood will know you for the green person you are (assuming you care about what the neighborhood people think about you).

How Does a Hydrogen Fuel Cell Work?

Lightweight, briefcase size Power Paks are deep-cycle rechargeable BATTERIES and Solar panel chargers in one unit.
Can be recharged three ways:
1) By Solar Panel (included)
2) By vehicle cigarette lighter adapter (included)
3) By AC Adapter (AC-IN optional accessory)
A good power source in case of emergencies. These Power Paks can operate: camp lights, radios, portable TVs, DVR, VCR, laptop computers, fans, test equipment, recorders, camera strobes, and they can trickle charge your 12v vehicle battery directly from the built-in solar panels.

Build Your Own Wind Turbine and Save on Energy Bills

Want to find out how to save the environment and money on your monthly electricity bills? Here’s the answer: build a wind turbine in your back yard. Much of the advertising for home wind turbines suggests that they cost thousands of dollars and take over your entire yard, but you can actually build your own for under $200.
Wind turbines can meet much of your electricity needs and if it produces more electricity than you use, the excess energy can be sold to your energy supplier, so you receive money back on your electrical bills. Sounds like a good idea, doesn’t it? Here are two sites that explain how you can build your own wind turbine:
Mdpub - If you are a hands-on type who likes a challenge and the chance to figure things out on your own, then following his advice is probably the way to go. The man at this website actually built his own wind turbine for $140.62! He goes into great detail explaining how he built it and you can follow along.
Earth4Energy - Here you can buy an in-depth manual that details exactly how you can make your own wind turbines and solar panels. His manual costs about $50.
While both appear to be comprehensive advice guides, the former is a little more my style. If you need more guidance, then the second one is better for you.
