Post harvest of agriculture produce processing,  energy   and  refrigeration.

    However   the  oil crisis is made vapor absorption refrigeration  system popular once again especially for industrial and agro industrial purpose. Japan has gone 70% of its refrigeration energy has been done by vapor absorption machine (VAMS). This type of refrigeration requires steam.

The producer gas from wood drives the diesel engine for rural and agricultural power. The producer gas from wood the diesel engine and the waste heat produces the steam requirement by Vapor  Absorption Refrigerating system for post harvest storage of vegetables, fruits ,milk and other farm produce .

Dealing climatic change will be India’s biggest ever  problem. The country’s  future depends on the  precautions  we  take  now.

Bio fuel alternative to transport fuel

The concept of extracting renewable fuels from plants or plant derived materials began perfectly begin and benevolent idea .With  today’s  level of atmospheric   carbon dioxide having already reached 383 parts per billion (p p m) -  en route  toreaching  the  critical  concentration  of  560  ppm  in 2050 widely believed to be the dangerous threshold  at which accelerated   and  severe  warming  effects  will  occur  -  the  duel promise  of bio-fuels of adding less CO2  to  the  atmosphere  when  burned compared  with  fossil  fuels  and  of   providing  two to  six times  as  much  energy  as  they  consume during  production  has proved   simply  irresistible  to  many  nations  across  the  globe

Thus beginning of   2008 ,the  European  Union  5.75  percent of  transport  fuels  from bio fuels  by  2010 and 10  percent  by 2020  . Meanwhile, the US aimed to increase the volume of bio fuel required to be blended into gasoline 34 billion liters to 136 billion liters by 2022.
With huge global demand of bio ethanol many US Soya bean growers switched to corn because of corn high selling price . Meanwhile to meet the rising global demand of Soya beans had an impact middle class in China.

Brazil expanded cultivating Soya on cattle pasture land. This made 292 sq miles (75628) Amazon forest was destroyed in 2008 alone for gracing of cattle.

 At the same time about 50000 sq miles (13 million hectare) rain forest in Malaysia and Indonesia cleared the rain forest and converted into oil palm. These massive clearing of rain forest is responsible for as much as 20% of carbon emission. This make 60 million indigenous people are at risk of being displaced.

The rush to produce bio fuels from corn, Soya beans and other food crops precipitated in astronomic rise in food prices around the world.

The bio fuel revolution has just begun in India. To develop beyond revolution confines, the hatchling sector needs a helping hand from the policy makers. Indiaplans to manufacture bio diesel from non edible vegetable oils. However thish as to be achieved without affecting country’s food security. Moreover like naturally water plenty Brazil, India cannot grow sugarcane only for ethanol production. Neither assigned essential agricultural land for growing viable non edible seed. For the projected 66.9 million metric tones for diesel by the end of 11th plan (2011-12). A 5% bio diesel replacement will need about 11 million hectare of land under Jatropha cultivation.  A rough estimate puts the figure around 1 million hectare on our green mile, the road is long but little traveled
