Question
What are the options to make sustainable biofuels instead of from plants?
We need better options than photosynthesis, that is less than 1% efficient. CO2 and light are abundant all over the planet. PV effciency is near 10% but make only electricity, when there is light (day ight) Are electrofuels a real option? Where hydrogen can come from? How much water electrofuels need? What about algae? Are they going to be produced industrially and economically? When ? What is the maximum cell density? How to separate them and extract value from biomass?

"Trouble in the algae lab for Craig Venter and Exxon"

In this article Craig Venter expects that a synthetic algae cell that has been constructed will lead to the construction of algae cells that produce enough bio oil to satisfy the market demand envisioned by Exxon. -
Also see http://www.algaeindustrymagazine.com/ since much of the information the Algae Industry Magazine reports and advertises adress the questions you posed regarding algae..

Thanks David!
What do you think about artificial photosynthesis? Or how to enhance plants to make biofuels directly? -
We are working with a seed from a forest tree. A single seed burns itself for 8-10 minutes. Does it sound interesting? -
It is a multipurpose tree. It could be useful to:
* Soil and river bank erosion. So plantable along the river embankments.
* wind barrier in cyclone prone area. So to the seashore and around homestead
* Could be regularly trained and pruned, so a lot of fuel wood as bi product
* Agroforestration in limited scale.
* Good habitat for birds.
* It is highly adapted to changing climatic conditions.
* Timber is hard and useful for housing and household materials

Zakir, what is the name of the tree? -
Dear Diego, We didn't give it a name yet.
If you feel interested to collaborate the research, please write to me in details. farmers.voice@gmail.com -
Ok thank you Zakir! I ll be in contact

My organization, Tubig Kanlungan (the watershed) Foundation Philippines separately tried and tested goat manure and rabbit manure for floating drum biogas digesters. Both work. The rate of decomposition is about 1 minute of methane flame per hour of anaerobic reaction. Our next step is to find ways to improve the rate of decomposition to 30 minutes of flare over 24 hrs. Thank you for your help.
