A bio-engineered algae may change the ecosphere by outcompeting other species that benefit the planet. Don’t think it can happen? Ask Floridians about the “love bug”.

What has been done over a million years by nature is to be replicated on the algae farm in a few hours with the condition that the whole process must end up energy positive. That is not going to be easy unless the laws of thermodynamics are turned on their head. Looks like we have no option but to be energy conservative till the day we learn how to tap nuclear fusion energy efficiently.

I’m into microbrews though. Hydrogen?(sorry last one said I)

The trick is in harvesting the extremely efficient system designed by nature to make an extremely inefficient fuel we can burn.If you look at any animal system and how energy efficient it is, there is no man made system that can even come close to the complexity while being as energy efficient.BTW, all the energy that keeps this planet ‘running’ comes from the sun. If we could only harvest a fraction of the energy that comes through the sky everyday we wouldn’t even be having an energy discussion.I am not really convinced that oil has a long term viability either. It just happens to high a high energy density, abundant, cheap and technologically very easy to convert into mechanical energy. The internal combustion engine hasn’t changed much since it has been invented in the 1800s. It is horribly inefficient to run. Looking at how much technology has advanced, it blows my mind that the best we can come up with is harvesting the expansion energy during combustion of an organic liquid. Really? We don’t even capture any of the heat energy! In fact, we do everything we can to bleed the heat energy away. The economics of the fuel is what has impeded the type of investment needed to pull us out of the 1800s.I sincerely hope we can make a little technological progress and pull ourselves out of the oil era.About me – PhD Biotechnology, Daily Driver – Viper V10 (Never said I was green)

Closed systems are out of the question, as the investment costs are about a 1000-times higher than for traditional agriculture, while yields are only a bit higher, whatever proponents promise. Worst is that the energy investment in the cultivation systems, and energy required to run and maintain the systems can never recovered.As for open systems, biomass yields are the same ballfield as tropical agriculture, but again investment and running costs are much higher. Just think of the energy required to concentrate the thin algaesoup, then extract the oil and convert it to biodiesel.By the way, quite a few of the recent startups have already folded again, because they could not deliver on promises. But, their managers were probably well-salaried as long as the investors believed the fairy-tales.

But if any of these green energy companies can not do the same, then I would hardly call this a viable business!There is a difference between an energy business and an energy social service agency!
