Powering the World with Solar Panels

Solar panels are getting more popular. Even the hardware stores have solar panels for sale now. But there are those who still say solar panels aren’t enough. We need additional forms of energy. The below link shows how much land would need to be covered with solar panels to supply the world with power. Let’s just say “not much”. And if you spread it out over a lot of houses and buildings, it could be easily accomplished.

Solar Panel Heater

A few posts ago I mentioned that I was building a solar panel heater ( also known as a soda can heater or solar space heater). Well, I finished the project, but have run into a small problem.

The solar heater actually works very well. Air gets pulled in through the bottom and circulated through the black aluminum cans and exits as hot air. It works just like it’s supposed to.

The problem I have is that attaching it to the house has proved more difficult than I thought. The area I originally planned to put it doesn’t get quite as much sunlight as I thought. Unfortunately, the house is made of concrete, so attaching it to the house and adding holes is very difficult. I am currently looking at mounting it in a different location and using long pipes to run it into the house.

Until then, here are some of the pictures from the building process.

New Solar Panels for Sale: Nanosolar

One of the biggest set backs for solar panels has been the high costs that it takes to manufacture them. This in turn makes their retail cost very high. Well, not there is are some new solar panels for sale in the market by a company called Nanosolar.

Nanosolar’s focus has been to try and lower the cost of manufacturing the panels so they can easily be produced. They have done this by using a special ink to literally print the panels onto a sheet. According to Nanosolar they can make their panels for about a tenth of what it costs to make panels currently on the market today.

Solar Panels, Solar Energy, Green Projects, and Evil Geniuses

Okay, the title is a little bit long. A few weeks ago on solar panels for sale I wrote about ordering some new books. In particular: Solar Energy projects for the Evil Genius, 50 Green Projects for the Evil Genius, and The Home Energy Diet: How to Save Money by Making Your House Energy-Smart. Well, they arrived and I have had a chance to take a look at them. And to be honest I am a little surprised at the results.

My primary purpose for these books was to see what types of helpful projects they contained for installing or making your own solar panels, solar heater, solar cookers, and other types of green energy. I was also hoping for tips and help on making a home more energy efficient. So what did I find out?

Well it depends on what you want. The one I was looking forward to the most Solar Energy projects for the Evil Genius turned out to be the one that was the least helpful. It had a few unique projects on making solar cookers or water heaters, but most of the projects seem to be more about learning a concept rather than something that is actually useful.

50 Green Projects for the Evil Genius actually turned out to be pretty cool. It has info on how to install solar panels on your house, make compost bins, build water purifiers, and a whole bunch more. The thing I liked about this one was that most of the projects were useful.

The Home Energy Diet: How to Save Money by Making Your House Energy-Smart also turned out to be a decent book, but only for someone who owns or is building their own home. It was very comprehensive on how to get the most energy efficiency with your house. However, it was also not a simple book. I felt like I needed to be a contractor to understand half the things I read through. Unless you are building or own your own house this probably isn’t a great choice.
