Renewable energy reduces our emissions Emissions that cause Climate Change Emissions that endanger our children
GM fuel cell carAt standard temperature / pressure, hydrogen is a colorless, odorless, nonmetallic, tasteless, highly flammable diatomic gas. Hydrogen is the lightest element. Most of the mass of our universe, about 75% is Hydrogen, Hydrogen is the most abundant element in the universe, making up over 90% by number of atoms. Most stars are mainly composed of hydrogen in its plasma state. Elemental hydrogen is relatively rare on Earth. Hydrogen can be cracked out of fossil fuel called hydrocracking) and ammonia production mostly for the fertilizer market. Water = H2O is an abundant source for Hydrogen by electrolysis - using photovoltaics makes this environmentally friendly with no greenhouse gases. You cannot see a pure hydrogen-oxygen flame, because it emits ultraviolet light. The main engine of the Space Shuttle is run by Hydrogen. Only with a flame detector it is possible to detect burning hydrogen, so leaks are difficult to find and very dangerous. Discovered over 500 years ago, Hydrogen was used in lamps, in balloons, the Hindenburg Zeppelin was filled with Hydrogen. Other uses were as a coolant, in batteries, and the military used it in Hydrogen bombs. Our Sun's energy comes from nuclear fusion of Hydrogen, humans still work on doing this fusion controllably on Earth. Hydrogen can be used in transportation - it burns relatively cleanly, with some NOx emissions, but without carbon emissions. For about a decade Hydrogen fuel cell have been built. They use hydrogen as fuel and oxygen - out of the air as its oxidant. Fuel cell cars and trucks are already running in many countries, they have a muffler, but all what comes out is WATER
At our Nature Preserve in the Texas Hill County we use the power of the sun:
A) to produce electricity with our windmill ![]()
B) to produce electricity with Photovoltaics ![]()
C) to warm up our water with the sun
Sunlight is Earth's primary source of energy. The solar constant is the amount of power that the Sun deposits per unit area that is directly exposed to sunlight. The solar constant is ~1,370 watts per square meter or ~1273 watts per 10 square feet Many names are used for equipment that is harvesting the sun: Solar panelsPhotovoltaic panelsHome solar systemPower from the sun Solar power Solar hot water panels solar thermal panels All these name describe the use of renewable energy. Energy that isn't producing air and water pollution Energy we can use without burning fossil fuels Bear Springs Blossom Nature Conservation is using Solar energy in different ways. YOU can do that too! We give information
You can get advice from us: It is easy to use the sun: Heat (hot water, building heat, cooking) Electricity generation (photovoltaics, heat engines) Desalination of seawater. Solar design in architecture Solar heating systems Solar hot water panels Solar cooking Solar lighting Photovoltaics Solar thermal electric power plants Concentrating collector with steam engine Concentrating collector with Stirling engine Solar updraft tower Energy tower Solar pond Solar powered car |
