1) Check out the Leonid shower tonight...
Video 1 Check it out!
Video 2 Check it out!
I wasn't able to actually view the Leonid shower from my apartment, which is smack dab in the middle of Little Rock, mainly since I don't have a very good view of the sky from where I live due to light pollution and the fact that my apartment complex is practically built into a hill. However, I did find a couple of videos that had some impressive Leonid shower displays. The first video shows a time lapse and is definitely worth checking out!
In relation to colonization, it would be quite interesting if we were able to colonize comets. Some cruise around our solar system, while others cruise in to our solar system then leave. To me it would be quite amazing to "ride" one of these comets and to explore the depths of space in more detail (Although colonization would have many challenges.)
Also, you may want to visit this "supporting" link for more information on colonizing our solar system that I found on wikipedia...it was pretty interesting! Click here to view the article. It mainly focuses on the most likely ways of colonizing our outer solar system.
2) Term projects...
My presentation is finished and has already been given to the class. Additionally, I have completed all of the research for my paper and just have the fictional section to complete. The other updated sections have been posted below.

Biofuel Power
Surprisingly, biofuels have been around for a long time, even preceding petroleum-based fuels, dating back as early as the late 1800s. In fact, ethanol (a biofuel often blended in today’s gasoline) was used to power early cars including Henry Ford’s Model-T (Biofuels Today).
Biofuels are renewable and efficient fuels that come from living organisms, organic waste, or food waste. To be classified as a biofuel, the fuel must contain at least 80 percent renewable materials (Biofuels). Additionally biofuels are clean burning—meaning they don’t contain sulfur—so when they are burned no sulfur dioxide gas is produced as is when burning petroleum-based fuels (Biofuels Today).
With these benefits, why are biofuels such a small part of today’s energy portfolio? The petroleum fuel industry saw the threat of biofuels taking over their market share, so the industry cut their prices, killing off their competition. By the mid-20th century, the use of biofuels stagnated and died out. However, as has been mentioned before, the energy crisis of the 1970s opened up a new door in the future of renewable energy, breathing new life into biofuels (History of Biofuels). Biofuels still supply a small portion of today’s energy resources. It will take another energy crisis like the ones of the mid-1970s to really boost biofuels presence.
Roadmap to the Future: Green Energy Production
What does our energy future look like? How are we going to get there if it is to be greener? What technologies will we see become more widely adopted, and when? These are all important questions, but it is often hard to come to a certain answer when new technologies and techniques rise year after year. However, after performing the research above, many of current key facts were assembled that aids in the projection of a foreseeable green energy future and the technology that could be used.
Our energy future will eventually make a transition into green energy whether we like it or not. Our fossil fuels are running out, as current research suggests that known reserves will last approximately 40 years for oil, 60 years for natural gas, and 120+ years for coal. Additionally, research suggests that biofuel, solar, and wind power will continue to grow making them cheaper and more widely available. Hydro power and geothermal power still have a potential for providing green energy, but will each only provide less than 10% of the total global demand. Nuclear power could still provide greener energy in a transitional period, if the need for energy couldn’t be immediately met by greener sources. Prospects of virus-assembled non-toxic green batteries, the successful zero-emission generation of power from coal, and the possible doubling of coals power generating capacity also provide hope to a greener tomorrow.
What my research fails to answer is that question of when green energy will come to provide a majority of the world’s power—a question which many others besides myself have posed. Although there is no definitive answer yet, it is possible to allude to one possible solution (See
“2109: A Possible Glimpse of the Future,” after Works Cited). Nonetheless, green energy will be an important part of our future when our natural resources have become depleted—the all important question that just can’t be answered is when.
Conclusion
Green energy technologies will most definitely play a vital role in our energy future. As our natural resources continue to deplete, major supplies of green energy will be necessary if we are to continue our traditional way of life when our resources finally do run dry. Biomass, solar, and wind power have the highest potential for growth; and if Harvard research is valid, wind energy may prove to be a key solution.
2109: A Possible Glimpse of the Future
Building up to 2109: A Transitional Phase
-Humans will start to drive plug-in electric hybrids instead of petroleum based cars
-Electric hybrids and electronic devices start to become powered by virus-assembled green batteries
-Coal plants will be retrofitted with zero-emission specifications that also implement the doubling efficiency coal effect
-Biofuels will start to replace petroleum based fuels in late transitioning petrol-car owners
-Electric plants will start to create power from biofuels instead of coal
-Solar panels will be incorporated in new building designs
-Wind turbines will start to dot the landscape more frequently
2100: Defining Point—End of Transitional Period
-Goal has been met—energy now primarily produced from biofuels, solar power, and wind power
-Nuclear, geothermal, and hydro power are still present from transitional periods
-Coal power is still produced but now new plants are being constructed as most are becoming phased out

Homework 13
1) Recall the relevant class. Comment on Toxoplasma Gondii. What do you think?
Toxoplasma Gondii is one scary parasitic protozoa. However, it seems that any situation stemmed from the current organism is manageable. Although the disease can cause adverse effects in humans, I don't think that it will ever cause an epidemic. Awareness to the disease is key, yet having rats as pets could reduce its presence in humans! :)
2) Add more to your project. Put the new stuff in a new blog posting. Consider new material that has some connection to Toxoplasma Gondii. Alternatively, it could have a connection to some other parasite or disease, or parasites or diseases more generally. Or it might be about something completely different...your choice!
New Sections:
Hydroelectric Power
As was mentioned earlier, the first hydroelectric plant was finished in Appleton, Wisconsin, in 1882. Additionally, it was noted that in 1925, hydroelectric power provided 25% of US electrical power; today, that number has dropped to a mere 5% (The Solar Guide). So why hasn’t hydroelectric power really caught on? Again, most of it goes back to that age old situation of coal and oil becoming the cheaper alternative. Additionally, environmental impact studies on surrounding ecosystems of current dam sites have shed negative light on hydroelectric power (Union of Concerned Scientists). If hydroelectric power is to ever become a significant part of our green energy future, these risks will have to be mitigated.
Wind Power
As was stated previously, utilizing the power of wind for useful purposes has been around for a long time. However, it wasn’t until the late 19th century that the power of wind was used to generate electricity.
In Cleveland, Ohio, in 1888, Charles F. Brush built the first large-scale windmill generating around 100 kilowatts of power per hour. However, many design improvements were needed to produce a larger amount of power, if these machines were ever to become feasible. That needed design change came in 1941 in Vermont, with a 1.25mW generating monster. The Europeans continued to develop and refine the former design, eventually leading to the modern wind turbines of today (Illustrated History of Wind Power Development). However, falling coal and oil prices stagnated interest in wind power, that is, until very recently.
In a new study published by Harvard University, the potential for wind generated power to supply a majority of the world’s electricity demand may not be too far-fetched. The new research includes a key factor that previous studies had not considered—the inclusion of wind towers that are 100 meters or taller, allowing for higher wind speeds in the upper atmosphere to generate more electricity than previously considered with shorter towers. The team then used data from thousands of weather stations to estimate the total world’s wind energy potential, assuming that 2.5 – 3 mW wind turbines were placed in unfrozen, non-forested locations, as well as some shallow offshore areas. Their findings were astonishing. Wind power could potentially generate 40 times the amount of current world power consumption. Additionally, they noted that the US could generate 16 times the amount of their current consumptions rates, allowing for the surplus of energy to be sold off, coining the US as a “Saudi Arabia of Wind” (Lorinc, John). If these findings are valid, wind energy may prove to solve the current task of finding viable green energy sources.
Geothermal Power
Geothermal energy utilizes the earth’s heat to produce energy. The Earth generates a vast amount of thermal energy. Geothermal energy applications first surfaced in Italy in 1904 with the invention of the first geothermal power plant. Interest in geothermal power stagnated until the 1960s, when the first geothermal power plant was constructed in the United States. However, even though there was a good deal of initial interest, geothermal applications were fairly expensive to implement, and the falling price of coal and fossil fuels led to a further decline in interest (RPEE-CREST).
More recently, research suggests that geothermal energy could be an important part in mitigating climate change by offsetting carbon production from other energy sources. So how much geothermal energy could the Earth potentially yield? According to the International Geothermal Association (IGA), temperatures at the base of Earth’s crust range from 200-1000 degrees Celsius. At the Earth’s core, temperatures soar to between 3500 and 4500 degrees Celsius. With these facts, it is believed that the total heat production of the Earth’s molten core is around 13 x 10 ^ 24 MJ, or Mega Joules. To put that in perspective—from physics, one joule is the amount of work required to produce a continuous watt of power for one second. A mega joule is equal to one million joules. In 2005, the world energy generation was nearing 6.6 x 10 ^ 13 MJ, so thermal energy appears to have a promising prospect in providing sustainable green energy (International Geothermal Association, 5-6).
However, it is impossible to utilize all that energy, as it can’t be evenly accessed across the Earth’s surface due to variations in the Earth’s core, volcanic activity, and magmatic activity under the Earth’s crust. Current research suggests that it is possible for geothermal energy to produce a maximum of 8.3% of the total world electricity, at current electricity demands (International Geothermal, 6-7). It seems geothermal energy could play an important part in a transitional period to a greener energy future.
Notable Recent Innovations in Green Energy Technologies
Another interesting technology has been recently demonstrated by MIT researchers, involving the production of green batteries from genetically engineered viruses. Essentially, the virus assembles the positive and negative ends of the battery using non-toxic substances. The entire process is environmentally green and can take place at or below typical room temperature. Practically speaking, the batteries could power plug-in hybrid cars and a host of personal electronic devices that use lithium-ion batteries (Trafton, Anne).

Homework 12
1) Suppose you had a coupon for a free robot. The catch is it can only do one thing. But you can get a robot that will do whatever one thing you like, just not anything else. What would you want your robot to do?
If I had the option for a free robot that could only perform one function, I would choose a robot that could repair any modern electronic device (cell phones, computers, televisions, MP3 players, etc) given the appropriate tools and parts. I find often that when these types of things break I usually throw them away and end up disappointed at the money I lost because it broke—it would be really nice to have a robot to repair that type of hardware!
2) Write or develop an additional significant piece of your project. As a suggestion, consider the connection of robots to your topic. However, if another subject besides robots seems more appropriate, that is just as good. Post the new section on your blog.
I have significantly updated my paper by revising the introduction and history of green energy technologies to flow with the rest of the paper (More Past-->Present-->Future, if that makes sense). I have also incorporated my official "Works Cited" into my paper citing the sources I have used thus far, as well as parenthetical citations. View an updated version here.
Additionally, per this assignment's instructions, I have drafted the following new sections.
Solar Power
As mentioned earlier, photovoltaics were discovered in the early 1800s. However, it wasn’t until the mid-1950s that the technology advanced enough (primarily due to the “Space Race”) to become practical and affordable. Nonetheless, cheap coal stifled solar energy research until the energy crisis caused by the Arab Oil Embargo of the 1970s warranted further research into alternative energy sources. The US Government invested heavily in solar energy research, thus leading to a reduction in price of solar panels and other solar implementations. However, the price of fossil fuels declined as solar panel prices fell, which led to a stagnation of research interest, and an eventual rise in solar panel prices (Southface.org)
As happened with nuclear power, countries outside the United States are beginning to significantly diversify their energy sources. For instance, Japan installed 25,000 solar rooftops in 2002 (Southface.org). Large orders such as this will help to lower costs of this technology; however, it will take more than one order of this magnitude to lower the price significantly enough to make it affordable to the masses.

Homework 11
Computing, Information and the Future, 11/2/09
Question 1
The discussion in class (Monday October 26, 2009, Prediction vs. Intervention; Weather vs. Climate; Trend Analysis) does not really apply to my project, “Green Energy Technologies: A Look at the Past, Present, and a Plausible Future to Sustainable Green Energy Sources.” In class, we talked about the weather and climate, and whether or not it was more feasible to control the weather or to predict the weather. Since my project primarily deals with green energy technologies, the only real application would be the seeding of clouds (controlling clouds) to enable more sunlight for solar panels; however, this would probably prove far too expensive in the real world. Additionally, we talked about trend analysis, which could be used to try and show trends in green energy technologies; however, I have already shown through pure fiscal figures that green energy technologies are growing and should continue to grow even more as the need for green energy rises.
Question 2
The discussion in class (Wednesday, October 28, 2009, Final spoil sports of prediction: existential angst; time value of money) can be applied to my project, “Green Energy Technologies: A Look at the Past, Present, and a Plausible Future to Sustainable Green Energy Sources.” First, when talking about existentialism in class, an important question was raised regarding societies’, “Failure to recognize a critical problem before it happens.” Many of us know that one day we will need sustainable green energy technologies when our nonrenewable resources that provide energy are used up; however, we may not necessarily realize the true depth of this problem until it’s too late. Additionally, TVM can indirectly be applied to this concept in that oil tycoons value their profits now, but may not be thinking down the line when those reserves run dry and they are left with nothing. Unless they invest in green energy technologies, their ‘reign’ would be over.
Question 3
I have advanced my project—here are the updated sections. I will post more sections here as they are finished/updated.
Introduction (Revised)
In a global society driven by the need for more energy, our world has grown accustom to accessing a seemingly endless supply of electricity primarily produced by non-renewable resources. However, as our non-renewable resources run out, the need for sustainable renewable energy sources have become a growing area of concern. Additionally, hot topics of global warming and rising energy demand have spurred an even clearer need for sustainable green energy sources.
Nuclear Energy (http://www.world-nuclear.org/info/inf54.html)
Although nuclear energy isn’t necessarily green, it may be an important part in a plan to provide greener energy during a transitional period from oil/coal to green energy sources. The science of nuclear energy (e.g. atomic studies and nuclear fission) was developed from 1895 to 1945. After the atomic bomb, focus shifted to containing and controlling the energy from nuclear fission to be used in the production of electricity. In the late 1950s and early 1960s, the first commercial nuclear reactors went live producing electricity. Orders flew in for nuclear power plants, and many were constructed and went live over the next two decades. From the late 1970s into the early 21st century, there was a significant decline in the construction of nuclear power plants. Oil companies that had entered uranium mining bailed out and the price of uranium dropped due to a consolidation of uranium providers. Then in 2004, three key factors revived the prospect of nuclear energy: 1) Projected increased energy demand worldwide, 2) Awareness of energy security, 3) Limiting of carbon emissions due to rising concern of global warming. China, India, Japan, and South Korea lead the way in constructing more nuclear power plants to supply this demand. The UK and USA must follow suit to keep up with the energy demand, or find other innovative ways to meet this need.
