I am sure that most of you are starting to understand how solar power is an important part of our energy future. Recycling old solar power units still holds some significant challenges, with most of this waste still going into the landfill; however, there is a lot of innovative research going on that promises some good solutions that should help solar power to be even more sustainable in the near future.
Solar power on a smaller scale is becoming common with portable solar units that can be used to power personal electronic devices. This link leads to an article about a solar charging device that sticks on your window like this one pictured below.
I have also noticed, in numerous shops, the proliferation of solar power units, such as radios and torches, which also have USB charging ports for other electronic devices. An additional benefit of these devices is that that they also have a dynamo, so if the sun is not out, turning the dynamo a few times will give you additional power from your own physical activity.
