Similarities

Finished in 2004. 15 floors out of which 11 apartment floors with independently rotating units. Each floor rotates 360 degrees, completely independent of all the other floors. Apartments sell for $400,000 each.

Scale of The Dynamic Tower is very large . In Suite Vollard , the things requiring water connections are in the static core.The

Both have a central core and a similar concept of building

Heliotrope House,Germany Actual image Designed by “solar architect” Rolf Disch, it rotates very slowly, just enough to track the sun and ensure the sail-shaped solar energy collector on the roof receives the optimum amount of sunlight.

Economic benefits :boost to tourism , cost of construction

is lower than normal ,office ,hotel spaces

will have high returns.

Mechanism of Rotation

Available InformationThe rotation was supposed to happen from the steel bearing rings. The diameter of the core is around 22 mts approx. and the power of 4 kw is required. Each floor will rotate a maximum of 6 metres per minute, or

one full rotation in 90 minutes.

Proposed mechanismThe mechanism of rotation is that there is a drive system located at the base of each floor .

The bearing ring and air cushion will help in rotating the tower smoothly .A few options available to power the rings is to install a motor at every floor .There an be a main generator

installed at the base of the building .A shaft running to the entire lengtH of the building would rotate continuously .whenever the user wants to rotate the floor he can simply connect his

floor level to the main shaft

CalculationsThe estimated power is estimated as 4 kw as recorded by the architect

as in .So going by this data , angular velocity:2/90 =6.28571/5400=0.001164 rad/sec power required per sec= 66.67 W

therefore torque required=66.67/0.001164=57273.76864 Nm.

Problems of electrical and water connectivity

• It would be better if the water connection requiring areas like washroom and kitchens are adjacent to the core .slots can be made in the core in alignment with the pipelines .Eg ,on the floors with 8 flats , eight slots in the core can be made at reasonable distances, which would be connected to the main water supply .And inside each apartment ,smaller water storage contains having a volume sufficient ot support a family can be installed .Whenever ,these subtanks are empty ,they can be refilled from one of those hoses in the core .

Wind turbines and solar panels

• The concept of VAWTs in between the floors and attaching solar cells on the floor tops will generate enough power to not only satisfy the electricity needs of itself but also other buildings as well.

• Each turbine can produce 0.3 megawatt of electricity, compared to 1-1.5 megawatt generated by a normal vertical turbine (windmill). Considering that Dubai gets 4,000 wind hours annually, the turbines incorporated into the building can generate 1,200,000 kilowatt-hour of energy.

Sustainable nature and contradiction

• Vertical axis wind turbines will be attached in between each of the floors and solar panels will be attached to the floors. Now the idea of attaching the wind turbines in between the floors looks very intuitive and vague. There are a lot of concerns regarding the amount of power generated from the solar panels. Going by the concept of rotation, people will try to align their floor in the best possible way and more or so ,their alignment will Co-inside . Like for example, in the morning, most of them will be aligned in the direction facing the sun. So ,as the result ,the area of solar panels which will be exposed for sufficient generation of solar energy is in deep question. Also, the dust storms in Dubai will give it a high time for the maintainence of the panels .Then ,in the generation of windmills, a sufficient amount of thickness ,length and exposure is required for the generation of energy of a measureable amount.Being in between floors ,the wind velocity for the turbine will be reduced and wind velocity is an important factor for generation of wind energy.(energy generated from wind mill is proportional to cube of the velocity.).It will also depend on the surrounding of the site where the tower will be constructed.If there are a number of obstructions nearby then the energy generated will reduce drastically .The tower would have to be constructed in a far area will lesser obstructions. As the wind and solar systems work continuously ,their costs can be eventually extracted In the long run. However ,their extra maintainence costs in a place like Dubai can be a problem where due to dust storms ,the solar panels will be all covered with dust reducing their efficiency .That would have to be taken care of.There are around 100 sandstorms per year ,some of them are quite severe.

Recent economic policy of Dubai

• One might have wondered Dubai has changed a lot in the last 40 years .The transformation in the skyline of this city is magnum .The economic policy followed by the government ,the liberal nature ,acceptance to foreigners , political stability and huge incentives to the locals have led to the transformation of Dubai from a gold and fishing industry to a tourism ,mass-communication , shipping and finance based economy.
