Dog Palace Solar Exhaust Fan kit. How does solar power work? Solar panels capture the sun's energy and use it to make electricity . The sun releases energy called photons, and the photons travel to earth. When photons hit a solar cell (solar panels are made up of lots of solar cells), electrons are knocked loose from the photons' atoms. The electrical circuits formed by the solar cells generate electricity when the loose electrons flow through them. The silicon solar cells are able to make electrical circuits because they have positive and negative sides, just like a battery--this in and of itself creates an electric field. When conductors (objects or materials that allow the flow of electrical charge; commonly metal) are attached to each side of the solar cell, that forms the electrical circuit for the loose electrons to flow through! Science is wild. Now, if you're really into understanding how this works, read on! If you got what you came for, feel free to scroll past.

Ever wondered why dogs are the animals used for search and rescue operations? What is it about their noses that makes them unique? Just what situations do they work in, exactly? Read on to learn the answers to these questions (and a fair bit more)! Photo credit: Peter Hershey (Stocksnap) Search and Rescue Dogs (SAR dogs) are employed by humans for a wide variety of tasks: they can help find people who are lost in the wilderness, patients who have wandered away from a care facility, or humans stuck in debris after a natural disaster like an earthquake, or snow after an avalanche. These trained dogs work well under pressure and have saved countless lives, well-earning the title of "heroes". Some suggest that a single SAR dog can do the work of 20-30 human searchers. You've probably heard that dogs have an amazing sense of smell, but do you know why? Dogs have over 100 million (some studies suggest between 125-300 million) sensory receptor sites in their nasal cavities (whic
