Perpetual motion machines

TePP periodically receives proposals for development of perpetual motion machines. We advise innovators to prove their new theory by referring same to peer referred journals. TePP is not competent to judge veracity of new theories. Apparently, devices such as these have been in popping up in news for a long time and are called perpetual motion devices. The US patent office however, discourages such claims and has issued a policy not to grant patent without seeing a working model. According Wikipedia no such device has been proven to exist.

If any one has knowledge of perpetual motion device in working, pl share with us.



Great innovations from small town India


August 25, 2006A bicycle that can peddle both on water and the road, a motorcycle used to pump out water from deep wells and a cellphone that can switch on electrical appliances within a specific radius! Self-taught mechanics in India are pioneering these and many more. With such inventions, self-taught mechanics or villagers with little or no formal education to their credit are transforming the limited opportunities available to them in remote and rural areas, say experts. "Formal and informal science can be linked to create new innovations and transform the opportunities available in rural India," says Anil Gupta of the Indian Institute of Management, who has taken upon himself to collect and collate such traditional information scattered all over the country under his Honey Bee network. Students of the Indian Institute of Technology, Madras designed jackets that could carry water after he showed them a picture of a woman carrying a pot of water across a vast and arid desert, Gupta says. Prem Singh, a class 10 dropout from Ambala modified his cellphone and it can now be used to switch any electrical appliance within a certain specified radius... all this development just cost him nearly Rs 2000, Gupta, who teaches at the IIM, says. Prof Gupta, who runs many self-development groups, says under National Innovation Fund of India it was essential to encourage youth, especially technology students to undertake projects that address real life problems of rural enterprises.Giving the example of an amphibious bicycle developed by a rural innovator Saidullah that could float on water and pedal on road he said it would if used during the recent Mumbai floods saved themselves from walking 20 to 30 kms to reach their homes.The professor, who in his spare time walks several kilometres through villages to collect such information, has suggested formation of knowledge centres in rural areas that would provide know how about scientific advances to innovators in villages.Gupta who has been working to bring such innovations to the forefront through the organisations of Srishti, Gian and NIF has already located manufacturers for some of these innovations.MIT has shown interest in the rope climbing device of the coconut farmer Appachan in Kerala and M-Cam ( a technology marketing firm in the USA has successfully sold a license to a Virginia based company for the manufacture of a foot operated spray pump developed in Gujarat.Gupta advocates for a change in the bureaucratic mindset and says officials "must acknowledge the limitation of our current institutions and knowledge management system and appreciate the need for a change."

I read with interest about the innovators from rural India and their innovations. I am a disciple of late Prof.Y.Nayudamma who brought in paradigm shift in the science and technology when he was Director General of Council of Scientific and Industrial Research during 70's. The Concept of TECHNOLOGY WITH A HUMAN FACE advocated by Mahatma Gandhiji and Dr.E.F.Schumacher's philosophy of SMALL IS BEAUTIFUL has still great relevance to developing countries like ours especially in rural areas. Through "Nayudamma Centre for Development Alternatives"which I founded in Nellore,Andhra Pradesh I have several inventions like Simple Solar Drier,Everybody's Solar Water Heater,Energy Saving in Electric Pumpsets,Pedal operated Battery charger,Pedal operated washing machine,Clay covers to reduce heat in concrete buildings, Device to drive the motor cycle when it is punctured,Air-cum water cooler,Fire proof Apron, Periscope to avoid accidents while overtaking vehicles ,Innovative Solar Disinfection of water etc., ,The efforts of TePP,DSIR; National Innovation Foundation, Rural Innovations Network in supporting Innovative ideas and projects is laudable.

Natural pesticide from Jatropa, Pongamia, Annona Squamosa Seed and

An indigenous and native wisdom approach to prevent pest attack has been developed by a local farmer in Andhra Pradesh, India. He has been successfully using this method in his Sugarcane, Banana, Grape, cotton,
vegetable farms.

250 kilograms each of Jatropa seeds, neem seeds, Annona Squamosa seeds (Custard Apple) and Pongamia seeds are crushed into a powder. In this 1000 kg powder is mixed D Compost bacteria. It should remain for a month. For this mixture is added one kg of B bacteria. This mixture is further kept for
a month. Afterwards one kilogram of Jaggery (product from Sugarcane) is mixed in 200 litres of water. From the mixture prepared earlier 20 kg was taken and mixed with jaggery water. This has to be kept for 10 days. This liquid has to be filtered. Now the natural pesticide is ready for use. Now 10 litres of the natural pesticide liquid is mixed with another 10 litres of water and sprayed on the crop. The operation has to be carried out at intervals of 7 days. For vegetables 4 times and for crops like cotton and grape 5 times this natural pesticide has to be sprayed. When the natural pesticide is sprayed on the leaves, the pests won’t touch them. The Farmer has been
practicing this method for over two years with excellent results. This method will keep the environment free from chemical pesticides.


D compost bacteria, B bacteria packets are available at biofertiliser shops at a cost of 2 US $ per packet. One kg of mixed seed powder cost 20 US cents. This natural pesticide is quite cheap compared to chemical pesticides
besides pollution –free.

In my Monograph as well as in my note on Rural Industrialisation – Leaf to Root Approach, I have advocated natural pesticide from Annona seed oil.
Another innovative method adopted by rural farmers is:
In the Groundnut (peanut) crop RED HAIRY CATER PILLER is a menace. This comes into open during nights and eats away the leaves. Local people put CALOTROPIS leaves in bulk at various places in the field. The red hairy caterpillar after eating Calotropis leaves further regeneration of the insect
is arrested. Perhaps the latex in the calotropis leaves is responsible for this.Calotropis is a care-free growth plant which is available everywhere. It is
also used as green manure.Yet another method employed is burning rubber tyres near the field in the
night. The moth of Red hairy caterpillar gets attracted to the light and falls in the fire.
Also to cure Foot and Mouth disease in the cattle, local people mix the juice of Annona Squamosa leaves with Turmeric powder and put it on the wound.
This is an age old practice prevailing in the rural areas.
Thorough research on these traditional methods will help to isolate the pigments which can be utilized naturally.In the early days people used to put goat and sheep skin in mud and put
calotropis leaves for three days to remove the hair. The latex in the calotropis helps to remove the hair from the skin of goats and sheep. Central Leather Research Institute, Chennai, India carried out extensive studies on this method and they isolated the active ingredient and patented it. Now this chemical is widely used to remove the hair in sheep and goat skin.

As teachers most of us are used to students and laymen approaching us with proposals to build "Perpetual Motion Machines." Newspaper reports in the past few days talk of an Irish Company having built one at the molecular/atomic level and advertising the same with full page ads.
I went to the website out of curiosity:
Many feel it is an advertisement gimmick - to attract attention - have a look and decide for yourself.

I want to share this information with all of you.

I have a gif animation of my working perpetual motion machine.

Where should I post this animation, so everyone can see that how is it working ?
