Bamboo
Strength and Durability
Bamboo is a fascinating material due to its incredible strength, regenerative
properties, and its natural aesthetic beauty. In structural engineering tests,
bamboo has a higher tensile strength than many alloys of steel, and a higher
compressive strength than many mixtures of concrete. It even has a higher
strength to weight ratio than graphite.
Bamboo has been used as the standard building material for the majority of
the world for thousands of years. There are many examples of buildings constructed
entirely of bamboo, which are now several hundred years old. Due to their
strength, these structures have even withstood 9.0 magnitude earthquakes.
Fast Regeneration
Typically trees such as the ones used in conventional wood fencing take 30-50
years to regenerate to their full mass. In the meantime, there is less oxygen
produced, less carbon dioxide consumed, and more soil runoff in the spot where
that tree was harvested - all producing negative environmental effects.
On the other hand, bamboo is the fastest growing plant on Earth. Some species
have actually been measured to grow over 4 feet in 24 hours. A pole of bamboo
can regenerate to its full mass in just six months! Bamboo can be continuously
re-harvested every 3 years, without causing damage to the plant system and
surrounding environment. During the time it takes to regenerate, the bamboo
plant's root system stays intact so erosion is prevented. Continuous harvesting
of this woody grass every 3-7 years, actually improves the overall health
of the plant.
It is believed that if bamboo were planted on a mass basis it could completely
reverse the effects of global warming in just 6 years, and provide a renewable
source of food, building material, and erosion prevention.

On average, if you install a solar water heater, your water heating bills
should drop 50% - 80%. Also, because the sun is free, you're protected from
future fuel shortages and price hikes. Other financial incentives include:
* Anticipated payback period of 3 to 7 years.
* Solar energy systems can take advantage of the sun's free energy year round.
* Solar energy can be produced even at low temperatures.
* Federal tax credits help pay 30% of the cost, up to $2,000 for the system.
Many states and utilities offer additional support (read
about the tax incentives of solar water heating).
* Between tax credits and energy savings, this system offers a faster return
on your investment than other solar energy systems.
* Lower first-time start up cost than solar photovoltaic (PV) systems.
