Basic computer skills must include basic keyboard skills.This computer basics tutorial includes where your fingers should be placed, what keys have special uses and what a key combination is. The picture below is of a typical computer keyboard. This key board may look like yours and maybe not they come in many different styles and looks. The correct way to place your [...]

Hi welcome to the basic computer lessons area. I’m glad you decided to look in on us. Everyone from young to old needs to have computer skills. If your new to computers you have a lot to learn. That does not mean that it’s hard or that you can’t do it. Please spend all the time you need doing the computer [...]

There are many active volcanoes in the world, but none as dangerous as was Mount St. Helens in Washington State. On May18,1980 the mountain erupted with a high-speed avalanche of hot ash, rock fragments, and gas called a pyroclastic flow which moved down the sides of the volcano. The explosion blew out the side of the mountain, knocked down thousands [...]

Often incorrectly called “Tidal Waves”, Tsunamis are usually caused by underwater earthquakes. They can also be caused by underwater land slides or volcanoes or even, rarely, by large meteoric strikes on the ocean. The waves are sent out in all directions.These disturbances are a series of ocean waves that send surges of water, sometimes reaching heights of over 100 feet, [...]

Tornadoes (or twisters) are vertical funnels of rapidly spinning air. Their winds may top 250 miles (400 kilometers) an hour and can clear-cut a pathway a mile (1.6 kilometers) wide and 50 miles (80 kilometers) long. Twisters are born in thunderstorms and are often accompanied by hail. Giant, persistent thunderstorms called supercells spawn the most destructive twisters. A change in [...]

Thunderstorms, also known as electrical storms, or lightning storms, are a form of weather characterized by the presence of lightning and its effect: thunder. In order to understand storms, especially thunderstorms, we must present a little elementary meteorology, a term invented by Aristotle about 350 years BCE, to mean study of the atmosphere. The study begins with the air , [...]

Seismology is the study of the solid earth’s motions, usually called waves. Wave motion can be started by explosions, earthquakes, landslides and thumpers. The earth supports two main types of waves: body waves and surface waves. The body waves go through the earth while the surface waves, like ocean waves, travel on the earth’s surface. Body waves are of two [...]

My last entry into my astronomy page was a blockbuster which I am sure I did not understand and I doubt that many of my readers were able to understand it either. I said the universe is composed of “hidden things” and that the stuff we are familiar with, such as ourselves, the earth, the solar system, atoms and molecules, [...]

Even though the electric car is seeing an increase in popularity these days, it was first invented at the beginning of the 20th century. The reason for it’s unpopularity at that time can be blamed on the access to electricity. Indeed, not every household where wired with electric energy. Thus, gasoline was way more accessible and the fuel engine cars [...]

Wanting to reduce our carbon emissions can get easy when we start by modifying our way of travelling around. These days, industries are adopting cleaner technologies since the demand for green products is rising. A popular transportation product in Asia called the electric bicycle is gradually taking his place in occidental countries. Also called the ebike, this vehicle can come [...]

Did you know that cars are solar collectors? Surprised, well just roll up the windows in yours and park it under the sun. Sunlight – powerful stuff; I don’t have to tell you what happens next. Doing what it does inside your car, just think what else it can do. Capturing sunlight is one thing; doing something with it is [...]

The purpose of a small hydroelectric power plant in a creek is to make electricity. Basically, you’re transforming the potential of flowing water into rotational energy. There are several ways to do this, you can build a Grand Coulee Dam size project, but on the other hand, maybe you’d better develop a small outback power system. If you’re still not [...]

The family’s recreational vehicles are uncovered, and readied for the open road. However, its getting poor MPG, puts a damper on the usual destinations. Whether you’re driving a 4X4 pickup with a camper, motor home, or fifth wheel and trailer, you can do something about it, and all without spending an arm or a leg. You can increase your recreational [...]

Pleasure boats come in all shapes and sizes; from 12 foot outboard skiffs to huge ocean going yachts with helicopter landing pads. To one degree or another, all have one common attribute, a hull. And thereon lies the (common) problem. The hull’s performance of all pleasure boats, unfortunately is susceptible to all kinds of water drag. Its design (shape), the [...]

Place any of a variety of photovoltaic materials in direct sun light and they immediately begin creating electricity. Their nature is to convert the sun’s photon’s energy into free electrical power – here’s how. By the way, the term Photovoltaics connotes light that produces electricity. Sunlight is made up of many different frequencies. For instance, placing a prism in sunlight [...]

Magnetic energy used in a zero point energy system is available 24/7… a Magniwork Powered System never stops generating electricity. Building the ZPE electric generator, with Plansusing magnets and other readily available odd and ends. It will give you reliable energy 24/7. There just isn’t antthing else like it. Take solar energy, if the sun don’t shine – no power. [...]

Maglev is an electromagnetic suspension system; i.e., an anti-gravity technology that allows heavy weights to float unassisted. Uses: wind turbines, trains, aircraft catapults, mining… Superconductor energy provides the magnetic force that defies gravity. Maglev bearings allow vertical wind turbines to turn on electromagnetic suspension. Such magnetic levitation allows zero-friction. To get an idea of the power that can be generated [...]

Hydrogen energy is an inexhaustible energy source. With one exception; it’s only unlimited as long as our sun exists, hummmm. After all, isn’t it the stuff that’s at the heart of our sun’s engine? And a very efficient engine it is. It produces the (link to solar power page) solar radiation, we know as sunshine. But let’s have a look [...]

Off Grid Living is becoming more attractive as solar photovoltaic technologies are improved. Thin film, state of the art solar is close to breaking the dollar a watt threshold. This is considered an important milestone, because coal is mined for use in producing grid power at about a dollar a watt too. When solar devices drop below that level, the [...]
