Cascade e-Ion vs Lasers

Comparisons

Comparisons with directed energy beam systems (Laser, Electron Beam to Sunlight). Note that the CleanElectricFlame® can be used as a narrow or wide area source (beam).  Some comparisons withLaser to Sunlight are provided.

(All information in general comparison tables like the ones shown below should only to be treated as approximate or indicative of order of magnitude)

Cascade e-Ion Plasma™ Laser Electron Beam Microwave Induction Sunlight
Surface Impact Beam 250mm diameter, large impact, improves productivity.  Large area allows for CleanElectricFlame® soaking at various power settings. Commonly available average beam size is about 2mm Commonly less than 0.5mm beam Poor Depth varies with frequency of machine. Varies
Welding/Joining Yes, even for dissimilar materials Yes, limited by beam parameters Yes, limited by beam parameters Very rare possibilities No for non-metals or poor electrical conductors like ceramics or plastics

Yes when metallic. Coils need to couple and sometimes be formed into complex shapes.

Relative Cost of Gas.  Compared to Air

Air 1
Nitrogen 10
Hydrogen 40
Argon 60
Helium 210
Vacuum
High kW
Drilling Yes Yes No
Vacuum Always Required? No vacuum required.

Plasmize air or other gases.

No Yes No

Cannot be used with metal.

Power Density 106-109 W/m2 106-108 W/mfor commonly used industrial CO2 continuous lasers. Depends on laser type. ~106 W/m2 Depends on acceleration voltage and wavelength of beam Low: about 1 to 2 kW for entire chamber.�Power density is low for surface. Bulk volume dominates as major term for power density. Efficiency depends on coil spacing, frequency and type of materials keep in coil. 1.3 x103 W/m2 (average)
Water Requirement None.  Adds to High Energy Efficiency. High High No Extremely high N/A
Energy Efficiency Very high Very low Very low Variable Very Low N/A

The relative price to use a gas or maintain vacuum is given above. .The SmartPlasma(TM) Cascade e-Ion machine can be used with air as the gas input.

Surface Deposition Comparisons

Cascade de-e-Ion Plasma™ Laser Electron Beam
Deposit Rate Very high, continuous, flexible for even Colloids and gels. Medium Medium, discontinuous
Species Deposited Atoms and Ions. Atoms and Ions Mostly Atoms
Complex Shaped Objects Good/Excellent, varying uniformity Good Poor, based on line of sight
Alloy Depositing Yes Yes Yes
Simultaneous Gas Heating Yes No No
Substrate Heating Yes Low Yes
Operational Costs and Capital Cost Small High High
