Bush shrub can grow in arid as well as more mesophytic zones. A large shrub, Euphorbia
tirucalli, is used as a hedge in
Brazil. The ability of these plants to grow well in dry regions and on land
that are not suitable for growing food, and the
fact that the oil yield from an Acre could be comparable to or better than
many other Biodiesel candidates (an estimate
of Oil Yield for milk bush/pencil bush is between 10 and 50 barrels of oil
per acre, ie., between 25 and 125 barrels per
Euphorbia tirucalli from Wikipedia
Species: E. tirucalli
Binomial name - Euphorbia tirucalli
Euphorbia tirucalli, pencil tree, or milk bush is a shrub
that grows in semi-arid tropical climates. Milk bush produces a poisonous
latex which can, with little effort, be converted to the equivalent of
gasoline. This led chemist Melvin Calvin to propose the exploitation of milk
bush for producing oil. This usage is particularly appealing because of the
ability of milk bush to grow on land that is not suitable for most other
crops. Calvin estimated that 10 to 50 barrels of oil per acre was achievable.
Milk bush also has uses in traditional medicine in many cultures. It has been used to treat cancers, excrescences, tumors, and warts in such diverse places as Brazil, India, Indonesia, Malabar and Malaysia. It has also been used as an application for asthma, cough, earache, neuralgia, rheumatism, toothache, and warts in India. . There is some interest in milk bush as a cancer treatment.
In the 1980s the Brazilian national petroleum company - Petrobras - began experiments based on the ideas that Calvin put forth.

About Oilgae - Oilgae - Oil & Biodiesel from Algae
has a focus on biodiesel production from algae while also discussing
alternative energy in general. Algae present an exciting possibility as a
feedstock for biodiesel, and when you realise that oil was originally
formed from algae - among others - you think "Hey! Why not oil
again from algae!"
To facilitate exploration of oil production from algae as well as exploration of other alternative energy avenues, Oilgae provides web links, directory, and related resources for algae-based biofuels / biodiesel along with inputs on new inventions, discoveries & breakthroughs in other alternative energy domains such as Solar Wind nuclear, hydro, Geothermal hydrogen & fuel cells, gravitational, geothemal, human-powered, ocean & Wave / Tidal energy.
