Summertime has officially arrived! Time to bust out the bathing suits and sunscreen and head out to the lake! To celebrate this new season and all the fun it brings we have decided to host our very first giveaway. This month we are giving away a Lighthouse USB Power Hub. This versatile piece of equipment is not only a bright LED lantern but also battery bank where you can charge any USB device. (Personally, I see camping more as a time to get away from technology but in case of emergency it is always nice to have a fully charged cell phone.) |

Greeks were the first to build their houses in a way that would benefit from the sun's heat during winter. 1767 Horace-Benedict de Saussure a scientist from Switzerland created the first solar collector in 1767. It was a sort of insulated box that used three layers of glass to absorb heat energy. This box was able to reach temperatures of 230 degrees Fahrenheit or 110 degrees Celsius and became known as the first solar oven. This solar oven was later used by Sir John Herschel to cook food during his South Africa expedition in the 1830s. 1839 This is the year Edmond Becquerel, a French scientist, experiments with two electrodes placed in an electricity conducting solution and discovers the electricity increases when it is exposed to light. This is now called the photo-voltaic effect. |
