I connected all the office coffee machines using a hot water tube, use just one to heat the water and distribute this to the others. Now I reduced energy consumption of almost all coffee machines 10,000 times, also I removed their water heaters to make them much lighter and cheaper. And still everyone here can enjoy (almost) as fresh and convenient coffee in every room, as the machines are still close to us.
