HEAVY WATER, D2O : It is extensively used as a moderator in nuclear reactors

Multistage electrolysis of ordinary water containing NaOH gives heavy water. The cell used for electrolysis, contains a cylindrical vessel made of steel as cathode while a perforated cylindrical sheet acts as the anode. The electrolysis is carried out in different stages.

Deuterium removal from water

What percentage of deuterium might be removed from water after a typical electrolysis procedure? From a post on this site I read that, "In the first stage, NaOHNaOH solution (initially 0.5M0.5M) is subject to electrolysis, until only 132132 of the original volume remains. This increased the original concentration of deuterium by a factor of 1212."
This seems to be, for the electrolyzed hydrogen, an approximate 38%38% decrease from the original concentration. If we assume the original concentration was 150ppm150ppm then after the first pass, we might expect to have 93ppm93ppm in the deuterium reduced hydrogen. If my estimate is valid, may I expect that each successive pass would reduce the deuterium content by a similar percentage?

HOW TO MAKE A NUCLEAR REACTOR BOMB ON THE BASEMENT

Two vacuum pumps suck air out of the central chamber, leaving a near-total vacuum. Loose atoms in here interfere with fusion and lower yield.
The chamber is filled with deuterium and jolted with about 45,000 volts of electricity. A negatively charged grid of thin steel wires attracts the now-positive particles, sometimes causing them to collide.
Colliding particles fuse to form helium-3. The resulting neutron emission is measured, proving that fusion occurred

Here are the minimum required materials:

-A vacuum chamber, preferably in a spherical shape
-A roughing vacuum pump capable of reaching at least 75 microns vacuum
-A secondary high vacuum pump, either a turbo pump or oil diffusion pump
-A high voltage supply, preferably capable of at least 40kv 10ma - Must be negative polarity
-A high voltage divider probe for use with a digital multimeter
-A thermocouple or baratron (of appropriate scale) vacuum gauge
-A neutron radiation detector, either a proportional He-3 or BF3 tube with counting instrumentation, or a bubble dosimeter
-A Geiger counter, preferably a scintillator type, for x-ray detection and safety
-Deuterium gas (can be purchased as a gas or extracted from D2O through electrolysis - it is much easier and more effective to use compressed gas)
-A large ballast resistor in the range of 50-100k and at least a foot long
-A camera and TV display for viewing the inside of the reactor
-Lead to shield the camera viewport
-General engineering tools, a machine shop if at all possible (although 90% of mine was built with nothing but a dremel and cordless drill, the only thing you really can't build without a shop is scratch building the vacuum 
chamber)

to extract deuterium is basicly : producible by electrolyzing ordinary tap water with a freshly-charged car battery

Remote Power Control For Battery Powered Devices

Thin conductors on both sides of a thin insulator are connected by wires to a remote switch. Slide it between the batteries. It breaks the connection until the switch is turned on.
