Solar power is simply the conversion of light energy into electrical energy using devices attached with special materials like silicon.Man has been late in harnessing the light energy from the radiant sun, a repository of unfathomable power. But nature has been using it for millions of years. Each of leaf of shrub, herb, or tree […]

Solar energy panels are photovoltaic (PV) devices to produce power from sunlight, the ultimate source of energy.
Solar energy is harnessed using photovoltaic cells. Groups of photovoltaic cells are known as solar modules. There are a range of products using single crystal solar cells producing 30 to 165 watts of […]

Tap water often contains impurities like phosphates, nitrates and heavy metals. Reverse osmosis water is compartively pure and is odorless and colorless. Water purified via reverse osmosis is free of dissolved minerals. It has the special property of being able to actively absorb toxic substances from the body and eliminate them. Reverse osmosis water […]

In the United States, reverse osmosis water filters are some of the most common household filtrations systems available. Reverse osmosis water filters are an extremely effective form of filtration. They are used in military installations where clean water isn’t readily available. They are able to filter a wide range of contaminants, including lead. The […]

Reverse osmosis is based on the process of osmosis. Osmosis involves the selective movement of water from one side of a membrane to the other. Reverse osmosis is also known as hyper filtration. It is the same process as used by a human body to filter out contaminants. Particles or impurities can be removed […]

The gas mask as we know it today evolved from inventions over time that were intended for use by deep sea divers, firefighters and mine workers. A popular misconception about the gas mask was that it was invented by Garrett A. Morgan in 1914. Morgan’s invention didn’t resemble anything remotely like today’s mask and […]

The very first known gas mask manufacturer was the German company Siebe, Gorman and Co which started as a manufacturer of diving suits and breathing helmets in 1819. Patents for air purifying inhaler devices were issued by the US Patent office as early as 1849. While these devices did not prevent the inhalation of […]

If you wanted to buy the very best, state of the art, modern, intelligent gas mask available in the world where would you go? You would look to a country surrounded by hostile enemies, with an educated, intelligent population and money to spend on researching and developing defensive weapons for its armed forces and […]

Surplus gas masks, old, discontinued, out of use gas masks are available from a wide variety of mail order firms that specialize in army surplus equipment. There are army surplus retail outlets and literally hundreds of internet websites. If there is ever a time to “let the buyer beware”, purchasing surplus gas masks is […]

The US Army became the largest user of gas masks just prior to America’s entrance into World War One. After that attack in France, there was no way a modern fighting force was going to be deployed against the Germans without the best equipment available to protect them from poisonous gas attacks. Plants that […]
