What solar panels should I buy?

“What solar panels should I buy?”   I’m asked this at least a couple of times a week.  It’s time to share the answer.   My answer is in three parts.   Part One: You’re not buying the panels, you’re buying the power.  What’s promised by the panel seller or installer or maker may not be what you get.  Sure, you’ll get the panel, but does it give you the power you were promised?  So the first part is to focus, not... Read More

Magic puddin’ pump pumps water 24/7 without electricity

  It’s magic.   It pumps water up to 200 metres above itself without electricity. Video Glockemann pump It uses the energy of flowing water to pump the water.

Wonderful design, wonderful ‘eyes’ in the designer for the gifts Earth has for us if we will look for... Read More
