I asked some questions few minutes back regarding g to save Energy by making some novel ideas, I wanted to know the global opinions. How many reply has been received so far. Please let me know.

Please read the results of “NASA’s Clean Air Plant Study” completed several years ago?
“Common indoor plants may provide a valuable weapon in the fight against rising levels of indoor air pollution. Those plants in your office or home are not only decorative, but NASA scientists are finding them to be surprisingly useful in absorbing potentially harmful gases and cleaning the air inside modern buildings.”
“NASA research has consistently shown that living, green and flowering plants can remove several toxic chemicals from the air in building interiors. You can use plants in your home or office to improve the quality of the air to make it a more pleasant place to live and work – where people feel better, perform better, and enjoy life more.”
TOP 10 plants most effective in removing: formaldehyde, benzene, and carbon monoxide from the air.

How does a three-phase motor save energy compared to 1-phase motor?
Someone told me that replacing my existing single-phase fan motors to three-phase motors could save me as much as 30% of energy. How is this so?
admin answers:
Three phase motors are more efficient than single phase motors. The three phases provide a method to produce a magnetic field that rotates smoothly around the motor. It also delivers power at a very constant rate. Single phase motors reverse the polarity of the magnetic field and shift the north of the magnet from one side of the motor to the other but they don’t have anything between the two sides to help the transition of the north pole from one side to the other. To get the motor started, they use an auxiliary winding and a capacitor to create an in between pole position, but that is not as effective as having three equal windings. In three phase motors, there are three equal voltages and three identical windings. Utilities provide three phase only to industrial users. Homes and small businesses can not get it.
Edit 1
30% energy savings is probably an exageration unless the fan speed can be reduced. A variable frequency drive (VFD) with a 3 phase motor can efficiently reduce the fan speed by any desired amount and save energy.
