B Rajaram to present paper on Gravity Towers at Paris meet
January 5, 2011
Our babus continue to ignore his inventions, while the world honours the technology man who patented an anti-collision device, made the Skybus and more recently the Gravity Power Towers
Rajaram Bojji, former chairman of Konkan Railway, never got a chance to implement his revolutionary Skybus project which would have provided inexpensive, air-conditioned mass transport without land acquisition! The idea, backed by 17 patents, was abandoned by Indian authorities despite a successful demonstration in Goa. But Mr Bojji, who is better known as B Rajaram, moved on to new research and has kicked off the new year with a bang.
Automated People Movers and Transit Systems (APM-ATS) has accepted Mr Bojji's work on Gravity Power Towers (GPT) as a peer-reviewed paper to be presented at its 13th International Conference on 24 May 2011. The biannual international meeting is being held in Paris for all those involved in the development of fully-automated people movers and urban transit systems around the world.
This is an honour for the man who invented the anti-collision device (ACD) for the Indian Railways and has already got 17 patents for his inventions. He has assigned the intellectual property (IP) rights of this technology to the president of India, which has the potential to generate additional revenues of between Rs300 crore and Rs400 crore per annum for the Konkan Railway.
In a message to Moneylife, Mr Bojji said, "With the GPT, the world will be benefited by a more economical and nature-friendly transportation system that runs substantially on eternal gravity. With GPT, the carbon emissions can be substantially reduced in the future. This totally automated system neither uses electrical traction motors on the rolling stock nor fixed signal train control systems. All it uses is automated energy control systems from gravity power towers, which can redefine our safety standards and lifestyle as well. It can be even adopted by the existing legacy systems. A dream of mine has taken the first step. Hope humanity benefits."
While, the Indian Railways is still 'thinking' about implementing indigenous technology, one of its technology drivers has moved on to bigger and better things.
Mr Bojji's GPT principle re-directs vertical-acting gravity force in a horizontal direction to create a tractive force on a mass on wheels-either rail or road-to accelerate, then sustain speed, and when decelerating to recover kinetic energy. It is almost like the action of a pendulum.
The recovery on the GPT system can vary from 95% to 70%, depending on the distance of uniform speed-the longer the distance, the lesser the recovery. Hysteresis losses owing to friction cause increased irrecoverable energy loss. GPT has been granted a patent in the US.
Mr Bojji has also presented the outline for a $450 billion scheme to create a cargo transportation network of about 100,000 km to be fully powered by the GPT in the US. The network, fully powered by gravitational force, would save around 97% of energy being utilised currently, and generate 30% surplus after meeting all expenses, while generating a million blog GPT.
It is estimated that gravity power systems could contribute 30-40% of the Earth's total energy needs, taking care of transportation of people and cargo, while attaining speeds of 360 kmph on rail-based systems.
Unfortunately, as the world rewards and awards the Indian innovator, the Indian government has shunned his solutions. The best example is the anti-collision device that he devised and which was given a patent, but the Railways have chosen to ignore it while trying to adopt the European Train Protection Warning System (TPWS) on busy rail routes. (Read, 'Is the anti-collision device system being derailed?' 'Why we are denying Raksha Kavach to rail commuters?')
Mr Bojji's other creation, the 'Skybus', was also left by the wayside by Indian authorities planning mass transit systems. Further, while the anti-collision device was singled out by the World Intellectual Property Office for special coverage, the Skybus Metro Rail System was described in special programmes on National Geographic and Discovery channels.
Mr Bojji was involved with the Konkan Railway project as chief engineer from the beginning of its construction in 1990, then as director for projects and finally as managing director between 1998 and 2005. He was instrumental in delivering more than 100 tunnels (including the Mumbai-Pune Expressway tunnels), about 2,000 bridges and 750 km of live running track through treacherous terrain in Maharashtra's Konkan region.
