Carbon calculator to reduce and offset carbon dioxide

Carbon calculator to reduce and offset carbon dioxide :
Whether we know or not, either directly or indirectly, Carbon Dioxide is added into the atmospheres by driving our cars, heating our homes and flying to a holiday destination and so on. If there is a suitable method available to calculate the emission of Carbon level per year, it will be better for us to reduce these emissions and offset what's left. There is a specific website provide for measuring the carbon footprint. There is a specif group called as carbon advice group which is working on reduce the effect of carbon footprint in the atmosphere. Once we join in this group we can become the partner of this green revolution.
HalfBanner

We can obtain the Offset of our Carbon Footprint, with a certificate, car windscreen permit-style sticker, Green luggage labels and window displays which can be demonstrated to our Green Credentials to your friends, family, colleagues, customers and suppliers.
Be an Environmental Entrepreneur and take part in the Green Revolution.

Harvest cheap energy from solar balloon

Harvest energy from solar balloon


As the conventional energy sources are going to exhaust very soon, the best alternative is the green technology like solar, wind energy harvesting so on. In this series, the Solar power harvesting has become more popular which is replacing the conventional energy harvesting. But it is too expensive while used commercially with high efficiency. In order to make it more efficient, solar light can be concentrated over the solar panels or cells of small area to convert into more electricity with respect to sunlight. Normally mirrors are used for concentration of sunlight to focus on solar cells. But this seems to be very costly and require more area.
Cool Earth Solar of Livermore, California, has invented a novel technique in order to better harvest solar energy with cost effective method. Yes, The new technology is the use of solar balloon. The solar balloon is a aluminized party balloons with one side transparent facing the sunlight. The solar cell is placed inside the solar balloon on which the sunlight is focused. The inner surface of the coated half of the balloon will act as a concave mirror. Now the balloon has become a cheap solar energy concentrator. Let the technology be the future cheap commercial energy source.

Tongue Control System for Disabled

Tongue Control System for Disabled
The technology never fails to help the disabled. Here the Scientists from Georgia Tech University hope have effectively using the ability to the mouthy muscle and turn it into a computer control pad. This computer controlled tongue power system could transform a disabled person's mouth into a virtual computer, teeth into a keyboard and tongue into the key that manipulates it all.
In the figure shown, the palatal plate (placed on a mould of the upper part of the mouth) with inductive coils and a silicone tube leading the wires out of the mouth. Right: The activation unit glued to the tongue

Their prototype Tongue drive system allows the disabled to manipulate wheelchairs by moving their tongue around their mouth, manage home appliances and control computers. The disabled have particularly high hopes that the tongue could prove the most effective.
The control system maps the motion of the user’s tonque to specific computer mouse or keyboard commands. The commands may be of left, right, forward, backward, single click and double clicks.
Compared to other control systems like tracking of eye movement are promising, they can be costly, slow and susceptible to mixed signals, this system is more cost effective and flexible.
The features of tongue control system are more flexible, sensitive and tireless option. And like other facial muscles, its functions tend to be spared in accidents that can paralyse most of the rest of the body, because the tongue is attached to the brain, not the spinal cord.
