Lessons learnt – 1

• Leguminous tree crops Negligible fertilisers Higher profit margins!


Bangalore 560003

16 of 24


• Trees Juvenile phase + cross pollination Graft for all commercial plantations to avoid this!


Bangalore 560003

17 of 24


• Canopy management:

– Make sure all available land area has leaf cover by the time plantation matures

– Plan plant-spacing accordingly

– Seed output heavily dependent on canopy area that sees the sun


Bangalore 560003

18 of 24


• No input means no output• Too much input is just a waste of

resources!

– Calculate how much the plant species needs & what rate it can absorb it at

– Anything less means less seeds– Anything more it will waste


Bangalore 560003

Lessons learnt – 5Stay Local

• As far as possible, select a species that belongs to the area– Good varieties are easier to find– Farmers are more comfortable with it– Yields are maximum

• e.g. – semi-arid areas – Castor, Pongamia– Coast – Coconut, Palm, Jatropha / Pongamia

With engines and expellers:

The bigger the better!!!

• Efficiency improves drastically with higher capacities– 5 kW engine < 2 kWh/lt– 1 MW engine > 4 kWh/lt

• Almost all engines are biofuel ready with very small modifications for the smaller, higher speed engines!

Additional case studies!

• Rudolf Diesel built the diesel engine to run on groundnut oil!

• Ford had a factory that made car bodies out of hemp fibres & ran the cars on ethanol from hemp

• Chinese ran their battle tanks on hemp oil!• Advantage over other renewable energy

technologies – over 100 years of R&D has already gone into diesel engines
