A forest in a skyscraper!


A US firm has conceptualised a self-powered skyscraper full of trees, to absorb and convert carbon dioxide


 
Nectar Design, a Californian-basedfirm, has created an unusual concept design aimed at provoking new ideas in the battle against industrial pollution and global warming.

This ambitious yet simple idea takes advantage of a “product” previously designed by Mother Nature herself – the tree.

The envisioned CO2 Scraper (pictured on top) would be a large-scale construction for holding between 200-400 large-sized trees that would potentially absorb dangerous pollutants and convert global warming-related carbon dioxide into breathable oxygen.

The creators understand that the Scraper would require a lot of refinement, research, and engineering to make the concept truly effective from an environmental standpoint.

“Right now this is a concept very much in the early idea stages,” said Nectar Senior Designer Yutaka Kazamaki, who has been spearheading the CO2 Scraper project.

“The issue of global warming is clearly among the greatest issues our planet is facing. The need to consider any and all possible solutions that address our environmental challenges have never been greater,” he said.

Designed to be placed near factories or other major sources of pollution, the CO2 Scraper would be a relatively simple concrete construction in which trees will be supplied with water and nutrients through a windmill-powered pump system.

Primarily, energy self-sustaining – the only outside power required in the current design would be electricity for an elevator to be used by maintenance personnel – the Scraper would absorb carbon dioxide and thereby increase the amount of life-giving oxygen in the atmosphere.

In addition, the structure would provide immediate benefits to people and animals in its vicinity, providing a significant amount of shade, while also cooling the air during the hot summer months via the temperature-lowering properties of hundreds of trees.
                    

The structure may be relatively inexpensive to build – roughly equivalent in cost to building industrial smokestacks – while still helping local economies by creating a number of green jobs during both the initial construction and later maintenance phases.

This concept has drawn early praise from scientist and sustainability specialist Joep Meijer, who founded The Right Environment – a consultancy for environmental products.

“Though in its infancy, the CO2 Scraper is an outstanding example of the kind of ideas we need to look at now. In a final version, it would be a great investment in natural capital for existing industries,” Meijer said.

“It would show a strong commitment and awareness to the environment as an integral part of doing business, as it’d bring improvements to the actual site, neighbouring communities, and local ecologies,” he added.

Pollution on Human BioSystem in Manufacturing of Carbon Nanotubes


One problem in manufacturing has always been worker safety. What will the future of OSHA look like in the United States? As other nations with no worker safety run forward in the Global Market they will enter their Industrial Revolution just like America did. But up until that point they will continue to pollute their water supplies and air and take advantage of their cheap labor.

The United States will have to relax their OSHA Standards or re-align them with reality. Some say any relaxing of such regulations will be a sham and an obvious and careless move against the American worker for increased profits and exploitation of our labor markets here at home.

In making new materials like carbon nanotube sheets many methods will be used such as for instance the possible use of frequency fields in the microwave area, chemical ionic bonding and high amounts of heat. All of which might be very dangerous to human beings.

Perhaps robots will be assigned such tasks, yet frequency pollution in the work place can be highly disruptive to the human bio-system and health. This can lead to free radicals, cancer or other diseases. Although these issues have not been satisfactorily addressed it is important to study along with the various methods being introduced to manufacture carbon nanotubes.

A schematic of each method must be studied to make sure, none of the polluted bi-products are released into the environment or in an area which they may enter the human bio-system. Due to the nature of working with such small dimensions, it maybe a painstaking set of procedures, which will need to be introduced to make the manufacturing of carbon nanotube material possible and safe.

As the industry attempts to address these issues and come up with adequate protocols everyone is concerned as we do not need a repeat of the Asbestos issues, which caused havoc and cost many their lives. So it is essential and paramount that we address these issues to the satisfaction of all.

Scientists are working on ways to do this now and learning as they go. Designing filters, which can protect us will be difficult due to the micro scale we will be working with, however there are ways to keep the particles controlled during the process. Next we must take this process to a much higher level so we can mass-produce them to help fuel efficiency and safety for all carbon nanotubes many uses.
