• Terrestrial plants convert solar energy with a mean efficiency of 0.1% by photosynthesis.
• Aquatic plants convert solar energy with a mean efficiency of 15 to 50%
• Photo voltaic captures only 18% solar energy, the world record for PV is 32%
• Solar thermal collectors are able to capture up to 98% of solar energy

Wonder seed Jatropha carcus
Density of plantation: 1100 to 3300 plants/ha.Gestation period: 5-8 monthsFull production capacity of trees: reached in ~5yearsEstimated seed production: 400kg to 12000 kg /ha/yearBetter condition of the land, better survival and seed production
For average fuel consumption of 15litres/month per person, we will need2000 to 3000 ha of land for plantation 925% to 38% of land in Auroville)for 2000 population.
