Hydraulic Technologies From Better World Technologies
The really interesting thing is that there is more than one way to do everything we are discussing in this brochure. We can get much the same benefit using hydraulics.
Refrigerants boil at very low temperatures at atmospheric pressure. The one in your refrigerator at home boils at 400 degrees F BELOW ZERO! They boil in the Super Heat Pump panel (evaporator) pretty much all the time, and when they do they build up pressure. This pressure is free because it comes from nature at no cost. Of course 8x3 panels can be put on truck or railroad car bodies as well as on a rack mount in the field. The pressure is not great enough to power an engine, but through hydraulic intensification it can be. When gas pressure is used to transfer energy to hydraulic fluid, the gas pressure is decreased. When the pressure of refrigerants is lowered enough, they compress back into a liquid at much lower temperatures. This pressure/temperature/intensification relationship gave us an idea...
Hydraulic Intensifier Engine
Hydraulic fluid can be used at high pressures to power hydraulic motors. This unit uses large volumes of lower pressure refrigerant gases to make small volumes of high pressure hydraulic fluids to power hydraulic motors.
Intensifier Concept (diagram)
The large chamber accepts the pneumatic fluid (refrigerant gas) into the top, which pushes a plunger down the chamber. An extension of the plunger, likewise travels down a smaller chamber to pressurize hydraulic fluid at a 15:1 ratio. Freon in a bottle at room temperature is multiplied from 150 psi and 2,250 psi hydraulic fluid produced.
Intensifier Concept (demo)
We hook up a refrigerant bottle (R-134a) and the room temperature gets the pressure in the bottle up to about 130 psi. We open the valve and it hits the gas chamber, which pressurizes hydraulic fluid to about 2,000 psi.
Hydraulic Wheel Motor
This motor is built right into the wheel hub. It can supply up to 500 HP using hydraulic fluid that is no more than 5,000 psi. Our evaporators sitting outside can get R-22 up to 400 psi. Fifteen x 400 is 6,000 psi hydraulic fluid.
Hydraulic Wheel Motor
Hydraulic Wheel Motor (diagram)
There are very few moving parts in this motor. It can run forward or backward depending on the direction the hydraulic fluid is injected. In fact, the best brake in the world is to suddenly inject the fluid the other direction (make sure your seat belt is fastened before you apply that brake)!
Semi-Stationary Hydraulic Motor Applications
We can use low pressure gases to take the energy from the air, converting the lower pressures to high pressure until gases are easily condensed. Stationary applications (wenches) or fork lifts with short lines or accumulators are easier because evaporator panels can be used on site.
The Alternative Processor
This is the part that goes into a home. The processor will fit into a foot locker box 2 x 3 x 2 and needs no monthly, weekly, or daily maintenance. It can be put under a stair, in a closet, or in the boiler/furnace room out of sight.
Hydraulic Farm Pump
In the LTPC Farm Pump, the mechanical energy drove the compressor. An Intensifier could eliminate the need for a compressor and all the energy transfers could be done hydraulically. The water pumped condenses the gas.
Hydraulic Electric Generator
This little unit demonstrated that we could have R-134a refrigerant from a bottle at room temperature, and flow it through an Intensifier to produce hydraulic fluid and power a motor that runs a generator that lights ten bulbs.
The Alternative Processor Close Up
The processor is really very simple with nothing to maintain. The compressor needs to be replaced from time to time (one unit ran over twelve years on the original compressor).
