18. In 2004, world required 220 million barrels of oil per day to run the world (equal to 14.5 terawatts)
19.
20.
21. 45% was generated by coal, 24% by natural gas, and 1% from petroleum
22. 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
23.
24.
25. Direct method is referred to as photovoltaic (PV)
26. PV panels collect the suns energy and transform it into usable electric current
27. Has evolved from powering watches and calculators into big business
28. Has doubled in energy production every two to three years
29.
30. 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 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.
