Diesel Facts

Industry standard diesel engines require ~54000 cc/m per Hp, and ~12500 cc/m per lb-ft of torque. 1 Hp = 2540 btu/h. Diesel produces 147kbtu/h.

The $10,000 "1000-series" Car

Inspired by "A Leaner Industrial Complex" , I am planning to make 1000, $10,000 vehicles.

They will come in two series: combustion and electric. Both kinds should be produced.

The cheap combustion engine should be an X4 running on diesel with compression above 25:1. I am going to try to make it a 2.4-stroke model, because that would allow far greater power from a far smaller [read: cheaper] engine, and probably a greater level of fuel efficiency. Also if it can be revved up to 10,000 rpm in the X-fashion and last 750,000 miles or more that would reduce the car's life-maintenance. Adding a torsion-assist would further reduce engine requirement and boost fuel efficiency. It could also be optionally cranked to provide "E-light power". A vortexed supercharger and vacuum appear to be part of the 2.4-stroke system.

Diesel could be replaced with hydrogen from a water splitter in a similarly equipped engine.

A 1-ton car could be pulled here by an 80hp acceleration-tuned diesel engine with a 15hp torsion assist. At ~10krpm using the 2.4-stroke system and 25:1 or greater compression, I would expect the diesel engine to be perhaps 0.4-0.5L. That is *tiny*. It'd get upwards of 90-100mpg. It'd have a 0-60 of probably 4-seconds. [1-ton, 95-hp, accel-tuned CVT & pistons, 10krpm]

The engine would probably account for $7000 of the vehicle. A CVT costs under $800. A tubelike exhaust and sound muffler, possibly coated with Italcement and LEDs,

If there is a water splitting furnace system available, the body could be made from spent coal bound into carbon fiber. Large and partially internalized bumpers attached to a metal and CF frame, around a CF or mesh rubber body should keep the weight low and the strength high, while minimizing cost around the water splitting furnace. This could be the one-ton car.

A small compressor and tank would allow instant-on heat and cool, too. This could be for the $40K model, but the above engine design could be either the $40K or $10K. I cannot decide. I reduce expense $0 by using a 4-stroke over a 2.4-stroke, or by using a gearbox over a CVT, or by using V# over X# engine type. Crappier is not cheaper here. I am planning to new-tool all of the 1000-model's systems. The costs are writing the software for and buying the machine and the material to machine, and assembling it. That means the fewer and more efficient parts, the cheaper and quicker. Designing a more complex or efficient part costs me $0 more, minus time.

Leather?

A registered and licensed automobile has basic standard inspection requirements. These vehicles can pass any emissions test, and having seat belts and 5mph bumpers should not be a concern. Safety inspection and crash testing are optional. Considering the special bumpers and frame and CF body, videotaping the crash and playing it for prospective buyers or investors should do the trick more than a few green stars.

Major costs for this would be the 3D printer, of which a single unit should cost about $30K, and the electric furnace powered by a water splitter for producing the car bodies, which combined should cost perhaps $30K. From there, costs would be in software programs, materials, and labor. Beyond that is testing, licensing, incorporation, and registration. I am sure Bermuda would not bug you. Using this method and producing 1000 cars annually with a 10% profit per car at a sale level of $40K should produce $4000 profit per car and have materials and repayment taken from the price.

That makes $4 million expected revenue on a regular line of production. That should be enough to employ 80 skilled workers. Can 80 skilled workers produce 1000 cars over [80X2000] 160,000 manhours? Each car should require no more than 160 manhours of work to produce, excluding machine tooling times. How many printers would be required to print all the parts for 1000 cars?

Next: mapping man and machine hours, closer blues of all parts, 1000-model electric vehicle.
