Then that 16-pound-per-gallon force that oil and gas want to come in with, you’re holding that down with the mud at 18 pounds a gallon.

The MHD(magnetohydrodynamic) generator... transforms thermal energy or kinetic energy directly into electricity. MHD generators are different from traditional electric generators in that they can operate at high temperatures without moving parts. MHD was eagerly developed because the exhaust of a plasma MHD generator is a flame, still able to heat the boilers of a steam power plant. So high-temperature MHD was developed as a topping cycle to increase the efficiency of electric generation, especially when burning coal or natural gas. It has also been applied to pump liquid metals and for quiet submarine engines.

Thermoacoustic refrigeration is a novel refrigeration process utilizing acoustic energy to produce heat pumping.

The National Earth Comfort Program is a collaborative effort between the US Department of Energy, the US Environmental Protection Agency, and private sector organizations interested in promoting the growth of energy-efficient, environmentally friendly heating and cooling technology. The GHPC' s specific area of interest is in increasing the use of GeoExchange technology for both commercial and residential heating and cooling. GeoExchange systems use the earth's renewable energy to provide heating in winter, and cooling in summer, with energy consomption 25% to 50% less than traditional oil, natural gas, and electric heat pump systems. Moreover because GeoExchange systems burn no fossil fuels in creating heat, they reduce greenhouse gas emissions substantially, and eliminate a source of carbon monoxide inside the homes and commercial buildings where they’re used.

The device works on the principle that gas is lighter than oil and rises. As well fluids enter the anchor, the gas breaks out of the fluid and exits the anchor through perforations near the top. The remaining fluids enter the pump through a mosquito bill(a tube within the anchor), which has an opening near the bottom of the anchor.

High-Consistency System. Figure 11-18 shows a representative system where pulp is handled in the 25% to 28% consistency range. Typically, a press is used to raise the feed consistency to about 30%. Fresh caustic or oxidized white liquor along with the magnesium protector is added to the pulp at the discharge of the press. A thick stock pump then transfers the pulp to a fluffer via a feed pipe in which a gas-tight plug is formed. The fluffed pulp flows down the pressurized reactor as a loose bed, while gaseous oxygen is continuously dissolved into the liquid phase and reacted with the pulp.... Oxygen gas is added to either top or bottom to maintain a partial pressure within the 90 to 130 psi range. Relief is taken from the head space at the top of the tower to remove combustibles and other noncondensible gases, and control overall reactor pressure. At the bottom of the tower, the reacted pulp is diluted with post-oxygen filtrate and pumped at about 6% consistency to a blow tank.
