I love this particular weblog, will certainly arrive back again. Please continue creating top quality content.
Professor Nocera’s lecture, as the respondents say, is difficult to critique without having the appropriate scientific knowledge. He introduces the issue of the amount of energy we are currently using in the world and the amount he calculates we will need by 2050. Then he questions the ability of any other known energy source to render the 2050 energy amount previously declared. According to him, not even combining all the sources, this amount could be generated.Subsequently, he explains his photosynthesis process which could take the water contained on MIT’s swimming pool and turn it into 43 TW. Assuming this is possible and that Nocera is able to surmount the problems associated to the process, such as the current high price of photovoltaic panels, giving poor people, what he calls the “non-legacy world”, access to cheap unlimited energy, at first seems like a good idea.Nevertheless, l agree with all the above claims about Nocera’s discovery not being directly applicable to the “non-legacy” world. The implementation of advanced technologies created in developed countries in the context of developing ones, calls for the consideration of local conditions for example: culture, available building materials, climate, lifestyles. However, this adaptation is often neglected, and, apparently, Nocera’s photosynthesis is not an exception.Before this technology can be massively introduced in the “non-legacy” world it would, necessarily, have to go through an adjustment process to fit with local conditions. Maybe the solution to the problem of installing it for people who do not have heavy structured houses to support them, suggested by Zahraa, could be going from thinking in individual energy production to communitarian energy systems, where a neighborhood, or community can install a structure to put the system and be in charge of its work and maintenance as a cooperative. Probably the adaptation of this technology is feasible, and the problem just lies in the way of illustrating it. When Nocera talks about energy systems for underdeveloped countries and exemplifies it with a picture of a house with a basement whose residents also have a convertible car, it seems as originally the system was not intended for “non-legacy world” people and maybe this was something that was adopted along the way. Independently of the details of the implementation of the system, the discovery, if possible to be scaled to satisfy massive demand of energy through local production, is a major discovery and certainly a paradigm shift as referred by Kuhn (1). Nevertheless, the discovery rises questions: what are the consequences of having unlimited access to energy? That would definitely solve the problem on pollution generated by fuel burning, but what would happen with consumption once the energy is almost free apart from an initial price of installation? If we are able to generate our energy in any amount we want, would that escalate the consumption until this new source is not able to sustain it any more?
As a final observation, I find Nocera’s comments on the need of education in birth control and other issues very interesting. While giving people the ability to produce whatever amount of energy they want would solve one environmental problem, it would still leave us with others or maybe generate new ones. Population growth affects, not only energy consumption levels, but also land used for food production, and CO2 generated as a consequence of that production. It would be interesting that scientific advances like this could go along with education programs that teach about the possible consequences of the technology being released and also about sustainability, and other social issues.(1) Kuhn, Thomas S.

Good – I should certainly pronounce, impressed with your web site. I had no trouble navigating through all the tabs and related information ended up being truly simple to do to access. I recently found what I hoped for before you know it in the least. Quite unusual. Is likely to appreciate it for those who add forums or something, web site theme . a tones way for your client to communicate. Excellent task.
Very nice layout and good written content , nothing else we want : D.
Apple now has Rhapsody as an app, which is a great start, but it is currently hampered by the inability to store locally on your iPod, and has a dismal 64kbps bit rate. If this changes, then it will somewhat negate this advantage for the Zune, but the 10 songs per month will still be a big plus in Zune Pass’ favor.
You are generally wrong and presume to find out me!
I am also a long time user of AFF and appreciated the flexibility it allowed in accessing data and creating user defined tables. I am very disappointing in the new version. I find that it is cumbersome, confusing and downright non-user friendly. I am estimating that the new version will, at the very least, double the time it takes for me to extract the data I need. For instance, I can see that it will be especially tedious to obtain block group information across county lines. I also found the help section very limited in the information provided. I will be reviewing the tutorials and hope that they provide more information. Although due time I much would rather skim a document then watch a video.

the Census Bureau is required to collect race data as directed by OMB.
Usually I do not read article on blogs, but I would like to say that this write-up very forced me to try and do so! Your writing style has been amazed me. Thanks, quite nice article.
These are glorious days for typography: the quality and quantity of fonts being developed is impressive. Also I’m cheap… I Always prefer your free font lists.
