DryWash™ is a fast, nontoxic dry-cleaning process based on liquid carbon dioxide (CO2) that is applied through high-speed fluid jets. Liquid CO2 is an odorless, nonflammable, nonhazardous solvent that effectively removes oils, sweat and dirt from a wide variety of fabrics. Both efficient and environmentally friendly, DryWash is the needed replacement for the hazardous dry-cleaning methods currently used.
DryWash cleans most linens, throw rugs and everyday or fine garments—even furs, leathers, suedes and items with sequins. It can be used worldwide by retail dry cleaners, hotels, military installations, corporate facilities, nursing homes and hospitals. Future applications include dishwashing and decontaminating machined parts. Eventually, small-scale versions of DryWash may be used in homes for cleaning laundry and dishes.

FacSim is an object-oriented program that models the operation of nuclear material processing facilities. It provides detailed calculations of the locations, amounts, and types of nuclear materials in a processing stream over time. These calculations are needed to both evaluate and enhance international nuclear safeguards.
- Evaluate and optimize nuclear material safeguards at
- Nuclear fuel reprocessing plants
- Nuclear fuel fabrication facilities
- Nuclear weapons disassembly facilities

In the near future, tens of metric tons of plutonium from nuclear fuel reprocessing and weapons dismantlement will enter the global energy economy each year. Ensuring that effective international safeguards are applied to this material to prevent its diversion for nuclear weapons poses a major challenge for the International Atomic Energy Agency. FacSim is a powerful tool for evaluating and optimizing nuclear safeguards to ensure that the expanding nuclear energy market does not increase the risk of nuclear diversion.

The MDH-1000 can produce hydrogen with a purity greater than 99.9999 percent from commercial gas cylinders (reagent-grade hydrogen typically has a purity of 94.6 percent) or from other impure hydrogen sources. The heart of the MDH-1000 is a metal membrane that separates hydrogen from other gases—with minimal auxiliary equipment—at flow rates over 10 times greater than that of any other hydrogen filter. The membrane is robust and has a long operational life. Moreover, the materials in the membrane are inexpensive. The MDH-1000 unit itself has several safety features that help to reduce the hazards of working with hydrogen.
- Ultrapure hydrogen is used to purify the silicon that goes into microelectronic devices. Increasingly, ultrapure hydrogen is also used to produce high-purity iron and steel, which have the superior magnetic properties that are required for high-efficiency electric motors, alternators, and generators. The MDH-1000 does not only provide ultrapure hydrogen for these applications, but it can also recover the hydrogen used in them or the hydrogen produced in other industrial processes.
- In the future, ultrapure hydrogen will be needed for proton-exchange membrane fuel cells to generate electricity at central and remote power plants. Ultrapure hydrogen also has the potential to replace the fossil fuels now used to power automobiles.
- About $160 million per year can be saved by using the membrane technology employed by the MDH-1000 to produce ultrapure hydrogen for purifying the silicon used in microelectronic devices made throughout the world.
- On-site production of hydrogen from methane or methanol is particularly important in Europe, where there are restrictions on transporting large quantities of hydrogen. Therefore, the MDH-1000 can play an important role in Europe.
- Proton-exchange membrane fuel cells—the most promising type of fuel cell for electric vehicles—require ultrapure hydrogen to operate efficiently. The MDH-1000 provides this purity at much lower cost than other sources, improving the economic viability of many fuel-cell applications. Using ultrapure hydrogen in fuel cells to power automobiles would eliminate the pollution now produced by fossil fuels and reduce worldwide dependence on fossil fuels.
