Superconductive and cost-effective electric wire strands

[Viewed 112 times]

We sell or license the US patent # 7,632,784 and a set of knowhow to commercialize our innovation "Superconductive ceramic coating electric wire strands" that can transmit 40x more electricity, have 10x less cost/performance ratio and as usable, flexible, durable and reliable as copper wire strands.

32 years ago, two Nobel Prize winners fabricated High Temperature Superconductor (HTS) ceramic particles that at easily achievable cryogenic temperature can transmit without heat losses enormous amount of electric current. Meanwhile, until now HTS electric wire is not yet on the open market.

We invented Chemical and Ceramic Engineering technology to produce superconductive ceramic coating strands. Our technology includes: 1) thermo-chemical nanotechnology of the sintered HTS ceramic material with superconductive nano-architecture, which obtains inner- and inter-crystal superconductivity of the integer ceramic body; 2) a method of dip adhesion coating of the metal substrate strand by HTS ceramics; and 3) a method of [metal substrate strand reel] to [HTS strand reel] industrial production of continuous HTS round strands that further can be twisted into multi-strand electric wire or cable of desired electric current carrying capacity.

Provided full dense sintering process makes continuous and uniform HTS ceramic coating layer of the strand completely integer to carry electric current. Sintered HTS ceramics are permanently reliable and durable in air or LN ambience. Nanofabricated and sintered HTS ceramic coating layer of 10-micron thickness is as flexible as metal substrate strand.

We invented and developed HTS ceramic coated strands with dia. = 0.06mm, which uses NiCr-metal strand substrate with dia. = 0.04mm. Our HTS strands at easily achievable LN temp-re can carry with insignificant heat losses electric current with density up to J = 8kA/cm2 while copper wire at room temp-re is used with electric current carrying capability J = 0.2kA/cm2, which is 40 times less. Meanwhile, at room temp-re, our HTS strands and copper strands of equal diameters transmit equal amounts of electricity.

Our US Patent and knowhow were approved by three groups of experts, 14 our peer reviewed journal publications, and presentations at 15 meetings of five US professional societies..There also published as: AU 2005324485 (A1) [Australia], JP2007533108 (A) [Japan], US7632784 (B2), WO2006076002 (A2) [International], WO2006076002 (A3) [International].

Invented flow chart of the thermo-chemical nanofabrication of HTS material and electric wire strands

1. Mechanical mixing in toluene solvent YBCO ceramic nano-particles, silver dope nano-powder and liquid silicone polymer additive

2. Ultrasonic agitation and homogenization of YBCO and silver-dope powders in silicone-toluene solution

3. FORMING STAGE: Dip adhesion coating of continuous NiCr strand substrate by wet powder mixture

4. Uniform orientation of the YBCO crystal grains along the strand in the permanent magnetic field

5. Polymerization in a tunnel oven of YBCO-ceramic-silicone-silver composite to provide the cross-linked polymer matrix with the embedded YBCO nano-size crystal grains

6. Ceramic firing consisting of seven consequent steps: drying, organics burn out, heating, incongruent melt sintering, cooling, oxygenation of the sintered composite to rebuild superconductive orthorhombic structure of YBCO crystals, and final cooling

7. FINISHING STAGE: Twisting HTS strands into a multi-strand electric wire or cable and insulation of this assembly providing dip silicone adhesive coating and thermal polymerization.

Invented HTS technology can result in:
1) Multi-strand HTS electric wire for: (i) electric motors, 1) Multi-strand HTS electric wire for: (i) electric motors, transformers, cables, and generator rotors with 5x reduced costs, weights, diameters, and power heat losses, (ii) cost-effective and smaller size electric grids; and (iii) MRI magnets,
2) Super-sensitive electronic sensors and signal filters;
3) Electro-magnetic propulsion engine for aircrafts and high-speed navy ships;
4) Superconducting magnetic energy storage (SMES) systems for an assurance of the electric grids and for fast recharging of electric cars to substitute large batteries;
5) Telecommunication and wireless systems;
6) HTS ceramic coated surfaces of any size and configuration;
7) Current limiters on the electric grids;
8) Pellets and other bulk leads for magnetic levitation (MagLev) high-speed trains;
9) Super-computer cables and wires; and
10) Super-collider magnets.

Financial information

Production cost of one meter of HTS strand with dia. = 0.06mm should be 0.17 cent. Our HTS strands at LN temp-re carry electric current as does it copper strands with dia. = 0.4mm at room temp-re. One meter of electric copper strand with dia. = 0.4mm costs $1.5. At the attractive price $1.01/meter for HTS strand with dia. = 0.06mm, production of, for example, 10,000km/year-HTS-strands would bring $10mill/year pre-tax profit and ROI > 200%. .

Electrical Engineering applications of HTS multi-strand electric wire would by 5 7x decrease cost, weight, diameter (size), and heat losses of electric cables, motors, and transformers used today.
The US Department of Energy (DOE) estimated the worldwide market for HTS electric wire and all its Electrical Engineering applications as $200bill/year where electric wire comprises at least 45% the total end-product costs or $90 billion/year.
