The technology itself impresses so much. The Car can run on a process of photosynthesis, the process which is followed by trees. It will take CO2 and exhausts OXYGEN.

Chinese automaker Shanghai Automotive Industry Corporation recently unveiled designs for a photosynthesizing concept car that could take in carbon dioxide and produce oxygen.

Some technical details as provided say that YeZ roof “absorbs solar energy and transforms it into electricity while spinning rotors on the four wheels generate power from the wind.” and it would have two-seater “metal-organic framework,” which would work to absorb CO2 and water, turning them into electricity that would get stored in a lithium-ion battery.

Well, looks like we are on a good way of developing eco-friendly cars a better way. It may take some more years to be available commercially.

The main cooling control of your house is its design. A well designed house takes into consideration the house’s orientation to make the most of prevailing wind directions and encourage favorable summer breezes.

Window sizes and placement also affect summer cooling. If the windows are located and sized well you can open them during hot summer afternoons and create a cooling breeze flowing through your whole house.

Your house’s orientation and shading features such as window overhangs and louvers effect how much sunlight is captured; a well orientated house will take advantage of the sun at different times of the day and during different seasons. Ensure that windows are big enough to capture free solar energy, but small enough to avoid any unnecessary over-heating in summer. Smaller windows will also reduce excessive heat losses during evenings, especially during the cooler months.

Room location is also important. By positioning the rooms which the family live in on the side of the house that naturally makes the best use of the summer sun, you will improve the amount of free solar heat your house naturally receives. Make sure that your deck also receives sun during the times you want it. Most people love to spend a few hours on the deck at the end of the day. A deck built to capture the evening sun and which is shielded from the wind can be used almost as another ‘room’, perfect for summer parties!

The thermal mass of your home is a key passive design component working like a sponge to suck up surplus heat during the daytime and releasing it later in the evening. Simple measures, such as replacing carpet with ceramic tiles will soak up the summer sun to maintain a steady cool temperature during the day and in the evening. But keep in mind: Thermal mass does not replace good insulation. Both go hand in hand and work best in combination.

If you don’t have a lot of thermal mass available, for example in a home with suspended timber floors, overheating can be a problem. External shades and sun sails can be fitted to complement the orientation of your house and assist with cooling. Tinted windows positioned correctly can also reduce the amount of solar heat entering the home.

Lastly there are also many cooling products available, namely air-conditioning units and fans. Commonly known as active cooling systems these offer a consistent room temperature, while at the same time, deodorise and clean the air, resulting in a healthier living environment for all the family. To maximize energy efficiency and ensure optimum home comfort we at Right House recommend that air conditioning units and fans are used as ‘extras’ supporting your home’s in-built passive design cooling features.

And remember, good insulation does not only keep the heat in during the winter, it also keeps unwanted heat out in the summer, reducing your air conditioning bill.

This is my second post on this topic, I came across an article in the section Education Plus of the newspaper The Hindu ( Hyderabad Edition), which shows a photo of a project and a small article on it which is completed by some students from DVR college of Engineering.

The students have developed a system that can convert your morning workout energy to electrical energy. The system can also store the generated power in a battery so that it can be used whenever required.

The system just looks similar to a bi-cycle. The power is generated by pedalling. As mentioned the model has a transmission ratio of 8. If a person paddles for half an hour, the generated power is suffeicient to light up two tube lights and a fan for two hours. The approximate cost s mentioned as Rs. 8,500/- I think it is reasonable for a Gym Owner to buy it.

I see it is a good model and should be encouraged, so that this can be made more optimized for better power generation. My idea is, this system should also be implemented in other workout systms of Gym, I hope it can done by using adjustable pulleys, belts, etc… so that a person can adjust the system according to his energy level during workout.

Results could be that if a Gym implements this systems, he can earn more by selling the generated electricity by peopple workouts or he can even make his Gym free for people and sell electricity. I think this should be calculated.

The earlier post I posted on this topic was in the month of September(2009) Dated 20.

EnviroMission Limited (www.enviromission.com.au) produced this 5 minute video on the pilot plant in Spain. It is an older video (2000) but gives a decent understanding of the solar tower concept. EnviroMission, Ltd. (US Market: EVOMY, Australian Exchange: EVM) is a renewable energy developer of sustainable “green” energy solutions for the energy market. EnviroMission aims to be one of Australia’s leading producers of clean renewable energy. EnviroMission holds the proprietary rights to Solar Tower technology, a large-scale renewable energy technology based on simple fundamentals of physics — hot air rises. Solar Tower technology has the potential to offer competitive renewable energy with equal reliability to fossil fuel generators. A single 200MW Solar Tower power station will provide enough electricity to power around 400000 households. The energy output will represent an annual saving of more than 1960000 tonnes of greenhouse CO2 gases from entering the environment when compared to brown coal emissions in Victoria. The greenhouse savings equate to the removal of approximately 500000 cars from the road. The Australian Solar Tower project consists of six distinct phases, the first two of which (project optimization and pre-feasibility commercialization) have already been completed. The third phase (final feasibility), paving the way for the implementation of the next three phases (final design, construction, and commercial operation).

The above photo displays the system installed on terrace of a Building for Cooking food. This is a very good way to save environment. This should be taken as encouragement and other colleges should follow or come up with better ideas than this. Same thing can be done to electricity.

Now a days so many power cuts being, will help this project to come up. This will be very much useful in village areas where they have to bear 8-10 Hrs a day power cut.

In this rapidly changing world we have to take steps in using Natural, Environmental Friendly, Non-Polluting methods. Some innovations like this should be promoted by government as well as Giant Companies.
