Nanotechnology is making the world Greener (speaker explains further)…Then Says, “so what is nanotechnology?”
We wrote you guys a book (We’ll do autographs afterwards). For now, we’ll take you through in 50 seconds.
Explain benefits of shrinking stuff: Medical machines small enough to go into the body (shrinking submarines), etc.
Nanotechnology has vast applications in making the world greener. We approached this problem by examining the application of nanotechnolgy to different industries.
Current forms are done so using mechanical energy that forces an electrical generator to rotate (called turbines) through the use of heat, albeit burning the fossil fuel
limited operating time replacement is needed. Disposal problem
The green initiatives realized from the applications of nanotechnology also extend to non-durable consumer goods, such as laundry detergents. One of the biggest culprits in ocean pollution, which endangers the environment by contaminating our groundwater, lakes, and oceans, is phosphates. This is commonly found in laundry detergents and some cleaning products. Janice Hughes, a publisher for a holistic health magazine called Share Guide Publisher, asserts that the average consumer nationwide uses about 30 pounds of laundry detergent a year.negatively affect the wild life in rivers, streams, and oceans by causing algae blooms
bend into numerous shapes, so it can be worn around the wrist or held up to the face; transparent electronics, which would allow the device to be see-through yet functional; self-cleaning surfaces that can absorb solar energy to recharge the phone's battery;
It is anticipated that the use of nanoparticles for water treatment will allow manufacturing that is less polluting than traditional methods and requires less labor, capital, land, and energy. For instance, new desalination technologies are being developed to remove salt from seawater for industrial or personal consumption. Because it is anticipated that less energy will be used, in comparison to standard water treatment methods, and because it is expected that there will be more precision in removing harmful particles, filtration may occur at a less costly and faster rate. This may prove especially beneficial to regions of the world that face water shortages as part of daily life. clean" polluted water, sifting out bacteria, viruses, heavy metals and organic material, is driving companies like Argonide and KX Industries, which developed technology used in Brita filters, to make nanotechnology-based filters for consumers. Two products incorporating nanotechnology are going to hit the market within the next year and are already being tested in developing nations.

A Greener World Via Nanotechnology<br />
Increasing World Population: Currently 6.8 billion as of April 2010<br /> Projected to be 9 billion by 2050<br />Malthus Theory<br /><ul><li>Stated that population would eventually outgrow its ability to sustain life and could not produce at appropriate levels (agriculturally and economically)
Has been proven inaccurate through innovations and technology</li></ul>But as population increases…<br /><ul><li>Increasing Pollution
Which brings us to our problem…<br /><ul><li> How will humans be able to support the world’s population growth rate, provide all the necessities required for life, and not destroy the earth (or each other) in the in the process?</li></ul>…and our potential solution…<br />
Currently<br /><ul><li>30 billion tons of carbon dioxide emitted yearly
Average American emits ~50,000 pounds of CO2 each day
In 2004, world required 220 million barrels of oil per day to run the world (equal to 14.5 terawatts)
Terawatt = 1,000,000 megawatts</li></ul>The Future of Energy Consumption<br /><ul><li>Estimated that we will need 60 </li></ul>terawatts by 2050!<br /><ul><li>Nanotechnology is giving alternatives </li></ul>to burning fossil fuels (solar and wind)<br /><ul><li>And nanotechnology is enhancing </li></ul>current energy generation methods<br />
Conventional Methods of Energy Generation<br /><ul><li> 70% of all energy generated in the world was done so by the use of nonrenewable energy
45% was generated by coal, 24% by natural gas, and 1% from petroleum
All three of above forms of electricity generation are done so using mechanical energy that forces an electrical generator to rotate (called turbines) through the use of heat, albeit burning the fossil fuel
Nanotechnology is helping increase the operation temperatures of materials, and reduces cracking</li></li></ul><li>
Solar Energy<br /><ul><li> Generation of electricity from sunlight (either direct or indirect)
Direct method is referred to as photovoltaic (PV)
PV panels collect the suns energy and transform it into usable electric current
Has evolved from powering watches and calculators into big business
Has doubled in energy production every two to three years
Nanotechnology helps efficiency through nanostructured anti-reflection layers which yield more light</li></li></ul><li>Wind Energy<br /><ul><li> Converting the earth’s atmospheric movements into useful energy using wind turbines, wind mills, and wind pumps
Very clean, renewable, distributed across globe, but it is also aesthetically unappealing ,loud, require frequent maintenance, and energy generated must be taken immediately
Nanotechnology is helping reduce weight, improve strength, and shed lightning strikes, and coating which reduce mechanical noise and increase longevity of parts</li></li></ul><li>Nano’sEnergy<br />
