    this could b the savior of the future lighting.. can you imagine the money you are going to save if you don\\\’t have regular electrical lights running in your home… I have seen where some people have actually gone with small solar panels to help offset the cost of electric for heating and cooling. electricity could soon become a thing of the past for a lot of homes…

    We are planning to start switching out the single pane windows in our 85 year old fixer-upper. I would also like chickens this year so that we can be a little more sustainable and have our own eggs, plus some bug control help in the vegetable garden!

    great idea and cost efficient! Hoping that 30 minutes will be extended to hours, so I don’t need to reset it from time to time
