|| Opinion: This post is so overcrowded with ads that only the top ads are in effect,while the rest are covered up. This is bad because the businesses that paid for ads will have wasted money, and because a lot oftrees would have to be cut down in order to produce all that paper.

Nuclear Notes

MISC.

-sustained nuclear fission generates electricity

-nuclear power provides 6% of world's energy and 13-14% of world's electricity

-US, France, Japan account for 50% of nuclear generated electricity

-2007 IAEA reported 439 operational reactors in world, in 31 countries

-150+ vessels with nuclear propulsion

-debate about nuclear energy: World Nuclear Association, IAEA, and Environmentalists for Nuclear Energy contend that nuclear energy is a sustainable energy source that reduces carbon emissions; Greenpeace International, NIRS believe nuclear power poses many threats to people and environment

-nuclear power plant accidents include: chernobyl disaster(1986); Fukushima Daiichi nuclear disaster(2011); Three Mile Island accident(1979); some nuclear submarine mishaps

-in terms of lives lost per unit of electricity delivered, nuclear power is safer than any other major power source

-nuclear fusion may be used in future

-china has 25 nuclear power reactors under construction, and plan to build many more

-in US, licences for half its reactors extended 60 years, and plans to build 12 more are under serious consideration

-Japan's 2011 Fukushima Daiichi nuclear disaster prompted rethink of nuclear energy policy in many countries: Germany decided to close all its reactors by 2022; Italy banned nuclear power

-after Fukushima, International Energy Agency halved its estimate of additional nuclear generating capacity to be built by 2035

USE

-2005 nuclear power provided 6.3% of world's energy and 15% of world's electricity

WATER POLLUTION: (Ilersich A., Betel Miri B.) Eutrophication:

-caused by farmers using fertilizer, untreated sewage effluent, natural situations in which the environment deposits nutrients into the water

-fertilizer flows into water, adding extra nutrients

-extra nutrients allow more algae to grow

-Sixteen nutrients plants need to grow and reproduce

-oxygen, hydrogen, carbon are freely available in environment

-rest are from soil or fertilizer

-

Research Questions

1. What is eutrophication? A: the addition of extra nutrients to water, causing an excess of algae to grow, taking more oxygen and suffocating the fish.

2. How does it affect the environment? A: all the animals above these fish on the food chain will die.

3. How is this a problem? A: Humans, who are at the end of the food chain, will not be able to fish which means some fishing dependent communities will die, which can largely affect the economy.

4. How many extra nutrients are added to the water?

5. How much more algae is made?

6.How much oxygen is removed from the water?

//X//.How can eutrophication be stopped/controlled? A: have a gutter to catch the fertilizer

Survey questions

1. Do you know about eutrophication?

2. ___ Video Game Design Values

-diver who goes under water and finds fertilizer

-diver is on left of screen

-fish come from left and move right at varying rates

-sidescrolls right; gradually increases as player survives longer

-diver has lives: if fertilizer moves of left side of screen, 1 life lost; if diver hits fish, 1 life lost; if fertilizer is collected, 10 points added; for every 500 points, player earns one life

-oxygen meter gradually decreases

-positive/negative power-ups respectively: extra oxygen, slower current, fish care taker; extra farmer load, faster current, extra fish load, fish food
