The Water Engine

The Water Engine is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand The Water Engine rather than just read about it. In short: The Water Engine is a 1977 play by David Mamet that centers on the violent suppression of a disruptive alternative energy technology. Plot Charles Lang works at a menial job at a factory and lives with his blind sister Rita in an apartment in Chicago during the 1934 Century of Progress world's fair.

Key takeaways

  • The Water Engine belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect The Water Engine to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of The Water Engine from memory before moving on to harder problems.

Reference excerpt

The Water Engine is a 1977 play by David Mamet that centers on the violent suppression of a disruptive alternative energy technology.

Plot Charles Lang works at a menial job at a factory and lives with his blind sister Rita in an apartment in Chicago during the 1934 Century of Progress world's fair. He is also an amateur inventor, and the play centers around a machine he designs that can create electricity from distilled water. Seeking to patent his idea, he finds a lawyer, Morton Gross, in the phone book and shows him the machine, but Gross's motivations seem to differ from Lang's. Gross recruits another lawyer, Lawrence Oberman, and together they menace Lang and eventually his sister. It is heavily implied that the two of them serve the corporate establishment whose profits Lang's engine threatens. By the time Lang realizes he is being taken advantage of, the lawyers have him trapped. He attempts to contact a newspaper reporter, but Gross and Oberman hold his sister hostage to prevent him from telling his story. He then meets a barker at the World's Fair right before it closes for the night who tells him of a chain letter he has just received, which gives him an idea. The lawyers try to force Lang into giving them his plans, but he says he no longer has them; the audience finds out from a scene in the newspaper reporter's office that he and Rita have been killed. The play ends with Bernie, a young friend of the family who has previously shown mechanical aptitude, receiving the plans for the Water Engine in the mail.

Themes The Century of Progress theme of the 1934 Chicago World's Fair informs that of the play. Technology is interspersed throughout the dialogue as the voices of various announcing figures, over radios, on physical soapboxes, and, in the case of the Chain Letter, of indeterminate origin, reinforce the notion of a rising tide of change as they herald the advent of a new technological era. The superstition represented by the Chain Letter contrasts with its eventual saving of Lang's invention and yet also coincides with it, as both the inventor and the letter seek explanations and justice in a world that often—particularly in the cases of both the lawyers, the knowingly bombastic newspaper reporter Dave Murray, and the Fair itself—seems more intent on flowery rhetoric than on the pursuit of truth or the greatest good of society. The play plays with the form of daytime radio serials, as its plot and structure, with clearly defined heroes and antagonists, riffs off the suspense thrillers that were popular around the time the play is set. That it was originally written as a radio play positions it as an homage to the genre.

Production Originally written as a radio play for the NPR drama showcase Earplay, The Water Engine was first staged at The St. Nicholas Theater in Chicago and later at The Public Theater in New York by Steven Schachter. It opened on December 20, 1977 and ran for 63 performances. The cast included Dwight Schultz as Charles Lang, David Sabin as Morton Gross, and Bill Moor as Lawrence Oberman. On February 28, 1978, it transferred to the Plymouth Theatre on Broadway as a double-bill with a short Mamet play entitled Mr. Happiness, and ran for 24 performances. In this production Patti LuPone was featured as Rita. The play was nominated for the Drama Desk Award for Outstanding New Play. The play was adapted by Mamet, Steven Bognar, Julia Reichert, and Martin Goldstein for a 1992 made-for-cable television movie produced by Donald P. Borchers, directed by Steven Schachter and starring William H. Macy as Charles Lang, John Mahoney as Mason (instead of Morton) Gross, Joe Mantegna as Lawrence Oberman, and Patti LuPone as Rita. Charles Durning, Treat Williams, Andrea Marcovicci, Peter Michael Goetz, Rebecca Pidgeon, Felicity Huffman, Ricky Jay, and Joanna Miles also were in the cast. It was produced by Amblin Television and broadcast by TNT.

Worked examples

Example 1 — a first encounter with The Water Engine

Start with the simplest possible case. Write down what The Water Engine claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to The Water Engine before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about The Water Engine ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of The Water Engine

In research
The Water Engine appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses The Water Engine in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
The Water Engine is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1977 plays, American plays adapted into films, Broadway plays, so understanding it makes those chapters shorter.
In everyday life
Look for The Water Engine outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
