And I guess one of the "biological problems" is how to get an increased amount of CO2 for algal growth? I read about somke from smokestacks of factories being fed to algae and in some cases sewage water being used for that etc...I am not sure if these can take care of all the yield requirements...as another observer pointed out, biomass burning might not be an ideal solution either...<BR/><BR/>Of course, the thing indeed is that lots of CO2 are present in the atmosphere, but how does one get a 10% increase ( if that indeed is the correct estimate) within a specific location where the algae are nurtured...while I do not have the answer, I really don't think this will be very difficult for some top scientists to solve...let's hope they get a solution quickly enough<BR/><BR/>A page that provides some more <A HREF="http://www.castoroil.in/reference/plant_oils/uses/fuel/sources/algae/biodiesel_algae.html" REL="nofollow">inputs on algal biodiesel</A><BR/><BR/>Vic, <A HREF="http://www.castoroil.in/castor/castor_plant_castor_bean.html" REL="nofollow">Castor Oil</A>Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9560953.post-1146225045375949752006-04-28T07:50:00.000-04:002006-04-28T07:50:00.000-04:00Most of what I've read says that for the best yiel...Most of what I've read says that for the best yield, algae require much higher CO2 concentrations than the 350 ppm in the atmoshpere. I've read 10% or more CO2 is best.<BR/><BR/>Given that some of the biggest biodiesel proposals I've seen involve coal-burning, I was simply offering biomass as an alternative. If you say that's unnecessary, bring numbers.johnhttps://www.blogger.com/profile/09690430991814528863noreply@blogger.comtag:blogger.com,1999:blog-9560953.post-1146223781754323632006-04-28T07:29:00.000-04:002006-04-28T07:29:00.000-04:00Wheeew"Algae-based biodiesel promises much higher ...Wheeew<BR/><BR/>"Algae-based biodiesel promises much higher yields, while not competing for farmland with food production. It does require a regular supply of CO2 that is much higher than atmospheric concentrations, but this can be secured a number of ways - burning biomass, for example."<BR/><BR/>Burning biomass? <BR/><BR/>No it does not require even more combustion, pumping air through the growing medium (waste water)will do just as well. It requires access to CO 2. There IS excess CO 2 in air and by providing extra air in the waste water the algae will grow faster just as it would with extra CO 2 from power plant smoke.<BR/><BR/>Bucky Fuller might not apreciate your blog name given this kind of basic misunderstanding.<BR/><BR/>The whole point of biodiesel from algae is to reduce CO 2 emissions.Anonymousnoreply@blogger.com
