Ⅰ. Introduction
ITER- Future Energy- Like a artificial Sun
Idea from <Sharing Science> 10, 2006 (an interview with Norbert Holtkamp, ITER Direct
or-General Kanme Ikeda)

Ⅱ. What is ITER ?
As a fusion future energy International Thermonuclear Experimental Reactor Iter : Latin meaning ‘the way’
Idea from - at the Geneva Summit, in 1985
Object demonstrate the scientific and technological feasibility of fusion
energy for peaceful purposes developing a viable fusion power reactor

Ⅲ. How it works
Fusion : Small nuclei can be combined (Deuterium) (neutron)
(Tritium)

Ⅲ. How it works
cf. Fission a large nucleus is split apart
Neutron + 235U → fission fragment + neutron + E

Ⅲ. How it works
Why is fusion better? the light nuclei are plentiful and easy to obtain - Deutrium : 0.03g/1L sea water → Same energy for 300L gasoline ( capability for 456km * 6 trip) - Tritium : convert Li ’s nuclei, Li reserves - 15 million years to use
Create 10 times more energy

Ⅲ. How it works
Safe and environmentally friendly - product He is not radioactive
- no greenhouse gases - low radio toxicity waste product

Ⅳ. Problems
Technology - constructing the device, Tokamak : a machine producing a torodial (doughnut-shaped) magnetic field for confining a plasma. * plasma : the forth state. An ionized gas co- nsisting of positive ions and free electrons in proportions reslting in more or less no overall electric charge, typically at low pressures or at very high temperatures

Ⅴ. Schedule & Latest News
E.U.(built in France), Korea, India, China, Japan, Russia, U.S.
Schedule General intent : in 2016, ITER begin operation It takes 25~30 yrs to common use
Total budget = about $ 6.5 billion

Ⅴ. Schedule & Latest News
Comparing : ITER is quite efficient
(fusion) ( atomic energy) (LNG) (petroleum) (soft coal)
