Problem
On the first day of winter old man Вова wanted to turn on his heater with input power 2 kW but found out that it was not working. Luckily, he realized that there was plenty of heat producing plutonium 237 in the warehouse where he was working. How much plutonium should he bring home in order to replace his old heater? You can assume that the plutonium is almost pure and that Вова has a lot of lead containers that can absorb all the energy radiating from the plutonium.
