A pair of entrepreneurs are planning to build and launch a spacecraft that, would carry and roast coffee beans in outer space.
The craft will use the heat of re-entry to roast coffee beans as they float inside it in a pressurised tank. The effect would be to roast the beans all over, and produce perfect coffee. The businessmen say that on Earth, beans can easily break apart and get burned in the roaster. But if gravity is removed, the beans float around in a heated oven, received 360 degrees of evenly distributed heat and roast to near perfection.
The spacecraft will reach a height of around 200 km. The beans would then be roasted in the heat generated by the craft’s 20-minute re-entry into Earth’s atmosphere. Temperatures in the pressurised tank will be kept to around 200℃.
Once back on Earth, the planet’s first space-roasted beans would be used to make coffee that would be sold for the first time in Dubai. This is where the pair’s company is based. It is not clear how much they would charge for a cup.
Surprisingly, the Space Roaster concept—should it go ahead—will not be the first attempt to take coffee into space. In 2015, two Italian companies, collaborated on the construction of a similar type of spacecraft, which was the first coffee machine designed for use in space.
Questions 19 to 21 are based on the passage you have just heard.
