Reference excerpt

The Boy Who Harnessed the Wind is a 2019 drama film written, directed by and starring Chiwetel Ejiofor in his feature directorial debut. The film is based on the memoir of the same name by William Kamkwamba and Bryan Mealer. It was screened in the Premieres section at the 2019 Sundance Film Festival and began streaming in most territories on Netflix on 1 March 2019. It was selected as the British entry for the Best International Feature Film at the 92nd Academy Awards, but it was not nominated. It received widely positive reviews with praise going to Ejiofor's direction and the acting. The film has been adapted into a stage musical of the same name, by the Royal Shakespeare Company and made its debut in Stratford-upon-Avon in February 2026 before transferring to London's West End for a 12-week season at @SohoPlace from 25 April to 18 July 2026.

Plot Born in Kasungu, Malawi, William Kamkwamba is a young schoolboy who comes from a family of farmers who live in the nearby village of Wimbe. William has a talent for fixing radios for his friends and neighbours and spends his free time looking through the local junkyard for salvageable electronic components. Although he is soon banned from attending school due to his parents' inability to pay his tuition fees, William blackmails his science teacher, Mr. Kachigunda (who is in a secret relationship with William's sister) into letting him continue attending his class and have access to the school's library where he learns about electrical engineering and energy production. By the mid-2000s, the family's crops fail due to drought and the resulting famine devastates Wimbe, leading to riots over government rationing. The economic effects of the September 11 attacks further devastate the country. William's family is also robbed of their already meager grain stores. People soon begin abandoning the village, and William's sister elopes with Mr. Kachigunda in order to leave her family "one less mouth to feed", but not before leaving a component of Kachigunda's bicycle that William requested of her. Seeking to save his village from the drought, William devises a plan to build a windmill to power the town's broken water pump. His small prototype works successfully, but to build a larger windmill, William requires his father, Trywell, to give permission to dismantle the family bicycle for parts, which is the only bicycle in the village and the family's last major asset. His father believes the exercise futile and destroys the prototype and forces William to toil in the fields. After William's dog, Khamba, dies of starvation, William's mother, Agnes, intervenes and urges his father to reconsider. William and his father reconcile after William buries Khamba. With the help of his friends, the few remaining members of the village and the component taken from Kachigunda's bicycle, they build a full-size windmill which leads to a successful crop being sown.

Worked examples

Example 1 — a first encounter with The Boy Who Harnessed the Wind

Start with the simplest possible case. Write down what The Boy Who Harnessed the Wind 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 Boy Who Harnessed the Wind 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 Boy Who Harnessed the Wind 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 Boy Who Harnessed the Wind

In research: The Boy Who Harnessed the Wind 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 Boy Who Harnessed the Wind 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 Boy Who Harnessed the Wind is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2019 British films, 2019 English-language films, 2019 biographical drama films, so understanding it makes those chapters shorter.
In everyday life: Look for The Boy Who Harnessed the Wind 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.
