Here are some more information for Plasma Air:
Scientists have proved that apart from the three states of matter which are known to them, namely solid, liquid and gas, there is a fourth type known as plasma. It does not exist naturally on earth. When a gas is heated to very high temperature, tremendous amount of energy is transferred to the atoms which ionize into its basic components, nuclei and electrons. Plasma is known to be an excellent electric conductor. Plasma cutters work by passing a gas through a narrow opening and bringing this in contact with an electric arc. The gas used can be nitrogen, oxygen, argon or compressed air. This causes the temperature of the gas to rise astronomically resulting in the production of plasma. This high energy released is passed to the metal under operation by the electrical conductivity property of plasma. Since the plasma is basically a fluid, it has the capacity to clear the metal surface devoid of the residue produced from the cut.
The main drawback of conventional gas cutters were that they were not able to cut metals with good conductivity. This disadvantage has been overcome with the new plasma cutter. The cutter can be used to cut mild steel, cast iron, aluminium, copper and stainless steel. Therefore they it is widely employed in industries where such operations are involved. The new plasma cutters are comparatively cheaper than conventional gas cutters which gives them preference over the older type of cutters. They have the added benefit of being user friendly and ensure economic advantages like minimized energy consumption. Since they do not require flammable constituents, the risk factor involved is much lesser. They can be operated on electric power or gas. There are cases where Nitrogen or highly pressurized air can be used.
Plasma cutters are considered to be more efficient than traditional oxy fuel cutters because they complete the work quickly and efficiently. Plasma cutters generate heat which is about 22000 degrees whereas the oxy fuels generate a mere 3150 degree Celsius. They can easily burn through most surface coatings such as paint and rust and still impart excellent cutting results. It is essential to have an idea how thick the metal is that you intend to cut with the equipment.
The thickness of the metal will have a direct affect on the size of the equipment required. For operations where cutting thin metals are involved, a smaller machine will be sufficient whereas to cut thick metals, heavier equipment is required. There are various models that are available and are unique in design and performance. The well known brands include Miller, Esbab, Lincoln and CNC plasma cutters. A Hypertherm plasma cutter involves working with plasma at elevated temperatures, therefore all safety procedures should be strictly adhered to.

The Best Air Purifers of 2007
My Search For The Best Air Purifier
Because of allergies and asthma I’ve owned over 56 air purifiers since 1974. And I even became a Health Practitioner in 1982 because of the way I overcame allergies and asthma naturally.
I’ve owned: Ozone air purifiers, Ionic air purifiers, Zeolite, HEPA air purifiers, UV light, Catalytic plate air purifiers, and water air purifiers with brnad namesincluding – Alpine Air, EcoQuest, Hunter, Panasonic, Austin, IQair, SunAir, and about 23 other “non-name” Chinese brands. (I avoided Sharper Image and Oreck because ionic alone just doesn’t do enough for me.)
So I’ll just say I have seen it all.
Last year Austin, IQAIR, Oreck and Sharper Image (their new models, not ionic breeze) made me an offer to distribute their products.
I said no.
Here’s why:
The No Replacement Filter Air Purifiers Don’t Do a Great Job
The idea sounds great but once you've seen a dirty HEPA filter (HEPA’s are a cloth-like filter which holds dust and pollution) you realize the ones without filters aren't catching very much dust or pollen – YOUR LUNGS ARE!
“No Replacement Filter Models” include:
Ionic Breeze
Oreck Models (they contradict themselves on their website. You have to replace filters, but they aren't HEPA)
Remedy – Get an air purifier that has affordable replacements. HEPA is important if you have allergies.
Most Replacement Filters (HEPA, Charcoal) are Over-Priced
In Japan air purifiers include 2-3 extra replacement filters. WHY? Because the Japanese think ahead.
U.S. manufacturers realize American's don’t think ahead so they overcharge. Once you purchase an air purifier you’ll be stuck paying what they ask. (Reminds me of my $89 inkjet printer –the replacement cartridges are $28!)
Remedy: Ask for filter prices first. Every 6-12 months you’ll need to change filters. And anything over $25 is too much.
Buying Hint: Ask for a discount on extra replacement filters before buying.
Most Air Purifiers Don’t Do The Square Footage On The Box
I called Oreck when their new $700 tower was listed as covering 1100 square feet. “How Many Times Does It Change The Air In The Room?” (which means how many times it will change all the air in that room). They didn’t know. Finally a tech said: “One per hour”. That’s poor.
Remedy: Make sure to ask for 4-9 “Changes Per Hour” per Square footage.(You may have to call the manufacturer) Square Footage as listed on the box is also based on an empty room.
So How Do I Choose The Right Technology ?
Here are some guidelines to match the basic technologies to your needs:
#1 HEPA, Pre-filter, Neg/Ion, Plasma Grid = Helpful for allergies and asthma, some odors
#2 Carbon, Charcoal, Ozone = Helpful for odors, smoke, animal smells, chemical sensitivity, VCO’s, and immune system
#3 UV, TiO2, Plasma Grid, Ceramic = Helpful for immune system (colds, flu, viruses, pathogens), and eliminating musty odors
New Sensor Technology There is a cool new technology from Japan that detects pollen. It promises to bring greater allergy relief. It continuously adjusts the purifier to the room saving electricity and guesswork.
What's great is that more manufacturers are now producing air purifiers that include multiple forms of technology.
CONCLUSION: Look for an air purifier that has HEPA, and 3-5 additional technologies such as UV and ion. Keep away from infomercial brands as the price markup is high. Expect to pay $250-325 (and don’t pay more). Make sure the replacement filters are reasonably priced.

I want to flush mount a plasma tv into the wall.How much air space do I need around the set?
Here is what Panasonic recommends for their plasma TVs:
"Leave a space of 3 15/16" or more at the top, left and right, and a 2 3/4" or more at the rear."
If you are wall mounting, leave a 3 15/16" gap at the bottom as well.
Volcano's Ash No Threat to Space Shuttle Landing
The ash cloud belched by an erupting volcano in Iceland may have disrupted air traffic over much of Europe, but it poses no threat to NASA's planned Monday landing of space shuttle Discovery, agency officials said.
