TN scientists branch out to building robot trees

MADURAI: Driving down a tree-lined road in 2020 might not have quite the meaning it does today, if a Madurai Kamaraj University experiment is successful. Its department of bioenergy and centre for biodiversity and forest studies is working to build 'robot' that will absorb carbon dioxide from the atmosphere.

The trees look nothing like the leafy, green ones we know and carelessly destroy, though they have structures that represent the stem, roots and leaves.

Each robot tree looks more like a giant fly swatter, but a single 'tree' can equal the carbon absorption of 1,000 natural trees. One 'tree' is said to have the capacity to absorb 90,000 tonnes of carbon dioxide every year.

The artificial tree comprises huge solar panels, representing leaves, constructed on the end of a tall plastic pole.

Tiny pores on the sides of the poles will absorb carbon dioxide from the air, which gets dissolved in a solution of calcium hydroxide inside, explains Dr K Muthuchezhian, professor and head, department of bio-energy and centre for biodiversity.

"Trees are the first line to fight global warming," he says. "But man continues to destroy forests, ignoring the dangers of global warming. Forests are being replaced by industries that emit dangerous greenhouse gases. Robot trees will go a long way in tackling this problem."

The energy absorbed by the solar panel leaves is converted into electricity. The solution in which the carbon dioxide is dissolved gets heated with the help of this solar power and is split into oxygen, hydrogen and water vapour, which are released through the outlets in the solar panel. Carbonic acid, formed as a result of the reaction, is released into the earth via the artificial root system.

The trees were invented by US scientist Klaus S Lackner, and the university is trying to build 'trees' based on his design. It has been estimated that 2.5 lakh such trees would be sufficient to control the emission of vehicles throughout the world at present.

At the rate at which we are going, we might have to live life like in the stone age to survive all the ills of modern technology. Pls read!

Where do you keep your Handphone normally?

This morning I heard a true and sad story from a colleague of mine. She told me one of her friends is always having abortions. When the foetus gets to be 2-3 months old she loses it. This happened several times over. The couple went to check with many doctors and at last one of the doctors examined the dead baby and found that the baby's body cells kept dying as the baby was growing in the womb until he/she could not survive.This was because her uterus was affected by Handphone Radiation.

The doctor told her she now has no chance to give birth to a healthy baby because the radiation has affected her uterus so that the major portion of the cells in her uterus have already died.

This happened because she has been keeping her hand phone in her working jacket so that the phone rested against just on the right spot of the uterus. She had been wearing it like this for a few years.

Please beware of this and take note if you don't want what has happened to this woman to happen to you.

Dearest friends & family members,

Please do not ignore hand phone radiation which will damage our health or body organs. Please put away your hand phone whenever you don't need it much.

Guys, Please do not keep your hand phone near to the kidney position and pants pocket as this will damage your genital area and affect your ability to father a baby.

The other doctor also advised another friend to keep her hand phone away from her new born baby to avoid radiation damage to the baby's brain cells.

Do not let the baby or toddler play with the hand phone. This is because the small young baby or toddler is still very fragile and growing, so he/she is much more vulnerable to radiation damage.

Please remember not to sleep together with your hand phone or put it next to your bed. Keep any other electronic goods (such as tvs) which also give off radiation away from your bedroom to reduce risk as we have to sleep a few hours every day in our bedroom at night.

Further, do not imagine that if you switch off the TV there will be no radiation. Actually it is still around in your room. It is not advisable to have even a small digital alarm clock close to your head while sleeping.

Take Care of yourself and your loved ones.

Thank you
Please pass this on to your friends and family.
I would rather be careful than regret not knowing
