What is BODHPS?
Real World I/O is expanding in scope and variety of products we are developing. A recent Patent (7,181,913) for the Steam-generating drive system (A.K.A. BODHPS) is enabling us to broaden our base and offer a number of opportunities for investment. This Boilerless On-Demand High Pressure Steam System is designed to replace the boiler and firebox in any Live Steam powered system. It produces steam from exhaust that would otherwise be wasted energy while offering the horsepower originally available from the host internal combustion engine.
How it works.
Internal Combustion Engines(ICE) are only 20% EFFICIENT(section 8.1). This device is a small addition to any engine that recovers the wasted 40% from the exhaust, as high pressure Steam Power. And it does this "On-Demand", meaning "as needed", so there's no need for large dangerous high pressure storage tanks or boilers. It's Boilerless design is a great safety feature which eliminates the danger of explosion. In addition,after being used, the Exhaust / Steam can be condensed and scrubbed of CO2 (carbon dioxide scrubber) and other pollutants thereby reducing Emissions. Any size engine can be used but as an example, when added to a 1hp engine this device provides an extra 2hp as safe usable High Pressure Steam On-Demand. The standard version will provide in the range of 40psi output. The original 1hp drive could be used to produce system power (electricity, hydraulics, etc) and propulsion for a wheeled vehicle (self-propelled application).

And for anyone wanting to understand the details of how an engine works and how I take advantage of this, there is a great WEBSITE that discusses the physics behind the processes.

Applications.
Here is a partial list of potential products and applications for the Boilerless On Demand High Pressure Steam System (BODHPS).
1) Replacement of firebox and boiler system in?,
Home steam heating and generator combination
Antique Steam Locomotive Engine
Paddle Wheel Steam Boat Engine
Steam Turbine Electrical Generator
Green house heating and Soil sterilization
2) Autoclave
Manufacturing of large vulcanized rubber
3) SteamJet powered boat see Mark15 torpedo for steam turbine example.
Pursuit Dynamics PDX see JetSteam.pdf for sdjp example.
4) Portable Dredging Machine pumps and Oil Spill Vacuums
Steam Driven Jet Pump SDJP
5) Orchard frost freeze prevention
6) Fire suppression
Output is large quantity of Steam and Inert gas
7) Portable Steam cleaning
8) Airplane de-icing unit
9) Sea water desalination
10) HyBrid / Tribrid Vehicle (any fuel, electric, and steam) Car and Motorcycle
11) RV auxillary power generator and steam heating in cold weather camping
Flexible.
Portable and resizable. Resize or eliminate the optional blue elements as needed for the application. For example the Transmission and Water Tank might be needed for a Farm Tractor and Frost Prevention application but not for a Steam Driven Jet Pump Boat application. And an Antique Train would not need the Transmission but would keep the Water Tank. A Heating application might use a larger Generator to supply Electricity in addition to the Steam Heat.

The Prototype is a WAD (Works As Designed). Details of improvements need to be protected until
more patents are applied for. So, I need to stop publishing my progress. I'll be back later.
Improvements have been made and preparations are being made for PRODUCTION!!!
Open Testing is done. Protected improvement has begun. Testing of Prototype 1B has begun...
Click here for a Power Point Presentation explanation of Prototype B testing for May 26, 2010.
Prototype B test results are in. And they are Amazing! The engine drives an alternator providing DC power to the load resisters. I calculate the engine produced 0.505 Crank HorsePower.
I measure Steam Pressure in the 0.5 in. dia. pipe before a 0.1875 in. Orifice allows the Steam to escape to the atmosphere at 14.695432 PSI. The Orifice Plate Calculator is used to find the Flow Rate per hour. I calculate the Boiler Horse Power then the Brake HorsePower equivalent of 5.9 HP from Steam.
Engine Horse Power: Ave. Volts x Ave. Current = Watts / 745.5 = HP
13.83 x 27.24 = 376.67 = 0.51
Steam Horse Power: Ave. Pressure Flow rate lb/min x 60 = lb/hr/34.5 = BoHP x 13.15 = HP
1.78 0.26 = 15.71 = 0.46 = 5.99
A thought or two on efficiency? As stated, Internal Combustion Engines (ICE) output 20% of the available power to their crankshaft (20% efficient). As engines can be thought of as a form of air pump, one can illustrate an interesting feature of BODHPS. As a matter of fact, I like to think of the inventers of the ICE as technicians looking at large air pumps of the time and thinking to themselves, "Hmmm, what if I just change the timing of the valves a little?" After all, the parts are the same. Add a little methane and a spark and stand back. Maybe the first insight was even an industrial accident where a pump sucking fumes from a mine shaft just ignited and became self-powered for a cycle. Revelation!
Anyway, back to efficiency. Power is transfered to the crankshaft of an engine by a connecting rod driven by a piston being pushed by the explosion of a fuel air mixture. The unfortunate part of this is that the explosion occures when the alignment of the parts gives the least mechanical advantage for the transfer; when the piston is near top dead center. Much of the energy is converted by friction and stress into heat as forces attempt, to push the crankshaft out thru the bottom of the engine and the cylinder to burst. Bearing and seals and other systems help reduce the evidence of this but the waste still occurs. The best option would be to delay the explosion to some point closer to 80 or 90 degrees after top dead center when the connecting rod has an angle on the crankshaft. But then, the compression needed for an explosion would be gone and the engine would not run. The next best option is what BODHPS does. The first exhaust valve opens just after ignition and releases this high pressure explosion into a secondary chamber for later use. It's my thought that this alone would increase efficiency even if the process just continued as in a normal engine. As a mater of fact, I use this mode for "warm-up" by holding the poppet valve closed for several minutes. So, this is one of the secrets of the BODHPS process. It bleeds of exhaust only at a time in the cycle when it would have otherwise been wasted; or worse, cause wear or damage. In this way a car engine wastes 40% as friction which is converted to heat. This is reduced by use of lubricants and dissipated by the cooling system (radiator). Any motor head will tell you, "You need cool air to burn efficiently." Otherwise you get detonation which requires higher octane, retarding the timing, and/or reducing compression. Without these steps you get reduced efficiency in the form of heat through the exhaust and less power through the crankshaft. Well, that's not such a bad thing for BODHPS because it's just a self-powered air pump anyway and efficiency is inverse to conventional engines. More heat out the exhaust means higher efficiency (better air pump). The power out the crankshaft is only a side benefit, so in-taking the air used to cool the engine is actually tapping into and recovering some of the power wasted in the conventional ICE as friction. MORE POWER! Of course, preheating the water before making steam, by cooling the engine with it achieves similar results.
