Gravity Powered Dedicated Freight Corridor for Indian Railways 29 Nov 2008

Seed Newsvine


Indian Railways are working on an important economy boosting infrastructure namely, the Dedicated freight Corridor-- A gravity Powered Dedicated Freight Corridor is worked out, along with project costs and returns expected. Saves 87% of energy in operations and primarily uses gravitational force to deliver cargo at a steady speed of 100kmph with handsome returns too. it can handle 160m tonnes annually in the first phase and has enough capacity to double if needed. A one page summary may be perused.

Energy independence , creating jobs & carbon credits!

Human effort should be such that we create wealth and not just spend. We must be able to create such assets which will keep on serving humanity at reducing cost of operation and maintenance while the initial capital cost too is the least. Energy independence and living with nature in unison and not in confrontation are primary requirements for sustainable development. Having said that, we cannot leave these words mere empty sayings. I do have an energy solution which meets these requirements. It is simpler than wind/solar energy and very economical more reliable , in fact as reliable as the earth itself. it is the gravitational force- unfortunately the solution is so simple and verifiable at the school graduate level with the result the esoteric scientists who want to operate at levels beyond common man's understanding , do not find glamor to consider and publicize.
The impact on world's energy scene with gravity powered towers is tremendous- using less than 3% of current consumption of energy, that means saving 97% of energy . we can move billions of tonnes of cargo all over USA day and night irrespective of climatic factors using only gravitational force- which is free from recurring energy costs, there is no generation or distribution costs. So year over year except for depreciation charges of the simple mechanical gears and cables in towers located every half a mile, the operation and maintenance costs drop.The 3% of energy requirement is at the Gravity Power Tower to make up for short fall in energy recovery of the moving masses, due to friction losses and this can be from solar/wind or even grid electrical power. How does it generate employment? Though in operation the rolling units with loads are all automatically handled, improving safety and made free from human errors, observers and supervisors at every tower will be needed to step in when a rare incident occurs to rectify and set the system on go. During construction, which is basically railroad construction technology, which could be elevated, on surface or sub-way, we do need employment in much larger numbers. Within USA we can construct a 100,000 mile network to start with kick starting the project in the first two years, to be completed within 4 years, the results start flowing within one year. There is no new research involved in implementing the technology. I estimate we need about 50,000 towers and linking rail track systems along with rolling stock, all of which will need an investment of US$150b and employing about a million persons of different categories from semi-skilled to highly skilled engineers including a few micr-processor experts. What are the benefits when we complete the project?
1. USA can stop importing more than 5 to 6 million barrels of oil per day starting from 3rd year, and at the end of fourth year almost 8 millions of barrels of oil per day can be saved.
2. Close to 3.5 billion tonnes of carbon emissions can be stopped and the carbon credits can be used to expand the network further. So practically the network will grow without further capital investment.
3. The million jobs created can be sustained by growing network and the maintenance requirements.
4. The cost of transport obviously drops, and makes tremendous difference to economy by making available cheaper goods and services to consumers.
5. All urban transportation can be taken over gravity powered sub-way system following the existing roads, with access at half a mile, attaining speed of 120 kmph, and average speed of 60 kmph, needing less than 5% of energy consumed today on rail.
6. Coast to coast and port to hinterland cargo movements become practically free transportation with gravitational force driving the system like a pendulum based clock work mechanism, needing less than 3% of current level of energy.
What action is needed to get this benefit?

This is US invention: US Patent 12154181 dt 07/31/2008. Patent pending.

I am grateful to God for the inspiration. Now I look for a visionary world leader to have self-confidence to examine what I say, and have just enough courage to announce support and initiate the construction of the first mile for the industry and business houses to jump in to take it forward. Actually the entire funding may then come from private investments! More importantly this development is without tears. No land will be needed to be acquired, as we follow the medians or shoulders of existing highways. It is also an environment friendly solution so will have support from all. We will involve all universities and engineering bodies to execute and not to keep conducting research with a distant dream of something turning up in near future. We change now the energy scenario in the matter of transportation. I can do it and deliver within first six months the world's first Gravity Power Towers, for which all technologies are available in USA - we need only variable gear transmissions, cable drums, steel cables and concrete structures. with intelligence embedded microprocessors certified to CENELEC standards. But to to take the first step we need a courageous leader who should at least give time to examine and and then convince himself to commit totally to the new world powered by Gravity!

Gravitons can move goods and people on surface rail saving 97% of energy!

EXTRACTS FROM A RESEARCH PAPER BY BOJJI R : RESULTS OF A COMPUTER MODEL.

5.2 Case of Gravity Power Towers located at 450m , with zero coasting length and peak speed of 108 kmph, acceleration at 2m per sec. For a rolling unit of 50T and driving mass of 1000T. Level and straight track chosen.


Table 1 Summary of results for transportation drawing energy from the Tower.
5.3 The results are summarised in the Table 1 under. The time taken is 30 seconds , average speed 54 kmph. The variable n(j) during acceleration, tand n(l) during deceleration, the tractive and braking force are plotted in the Figure 2.


Figure: 2 Constant acceleration case with variable gear.
5.4 More importantly the energy recovered is 97.7 % approximately- which means we need less than 2.3% of man made energy ; in other words we have opportunity to save more than 97 % of energy which we currently are using from fossil fuels! With this speed profile, Figure 3, urban transport with stops within 500m can be created, practically powered by free, eternal energy which is pollution free- that is gravitational force driven.



Figure 3 Speed profile for the 108 kmph short haul case.
5.5 It is beyond the scope of this paper to describe complete engineering details for implementing in field, but it is necessary to note that surprisingly for such a significant alternate source of energy to be availed, it is not as complicated or complex as it is in case of wind or solar power. Only variable gear transmissions readily available in industry, cable drums to roll up and down the vertically moving masses, endless thin steel cable transmission running around pulleys, sounding more like old world technologies, except for microprocessor based low power driven electronic intelligence to initiate or stop certain connecting gears form the components of the Gravity Power Towers. The rolling stock and railway track are substantially the existing ones, even simpler because there are no prime movers mounted on the stock, it is merely hauled by the cable. Hence the risk of technology complexity for quick realisation is practically little.
5.6 For long distance travel without coasting length, such speed profile can cause concern of human comfort. In such a case accepting saving of 60-70% levels of saving, Fig. 4, we can work out high speed travel option with coasting

length. But for transport of goods this can be a boon. Billions of tonnes of cargo in containers can be transported across globe on surface, saving more
than 97% of currently used energy.

SO gravitons can provide all the energy eternally to move billions of tonnes of cargo to any point on earth, on rail, using only 3% of current energy consumption. This has very high impact on reducing global warming and controlling climate change. For USA alone it is estimated that close to 3.5 billion tonnes of carbon emissions can be avoided annually.
