How Does Solar Energy Work – A Basic Guide

How does solar energy work? It’s a question that’s being asked increasingly often now that solar energy is becoming much more practical, marketable and affordable. It’s not uncommon for you to see advertisements for home installations and comparison charts between competing solar energy companies. What goes on behind all those pricey panels, and is it really the next big thing like everyone says it’ll be? A Short Solar Energy Guide If you’ve ever seen a calculator that doesn’t need a battery to run – the ones with a black strip near the top front – then you’ve seen a solar cell. Photovoltaic or solar cells are specially designed modules of treated silicon that can generate an electric current when hit by light. In a nutshell, electrons in the cell’s silicon lattice can be struck loose by the energy of the sun, and their movement creates a current in the cell. With enough cells in place, this generated energy can add up to a significant amount – enough to power a home or building in som

Why use a Barbecue Meat Thermometer?

When you’re barbecuing large joints of meat and birds like chicken and turkey it’s not always easy to decide about when they are cooked well-enough to eat. If you barbecue for too long over-cooking can result in dry and unappetizing meat, but if you don’t cook for long enough there’s always a chance that dangerous bacteria (such as Salmonella and E. coli) which are often present in the raw meat will not have been eliminated by cooking and could cause illness. Cutting and piercing a large piece of meat to check on how well its cooked can be “hit and miss” because using this method it’s not easy to judge when to stop cooking if you want your lamb or beef rare or medium-rare or your duck pink.  There’s always a worry that you might not have cooked it long enough to be safe. But there’s a way round these problems – use a barbecue meat thermometer. Meat thermometers have been around since the days of the Victorians, but with reliable modern ovens they aren’t used as much as they used to be.
