Supply of Boiling water without power outlet
This weekend coming some friends and I will be running a cake stall at a local vintage fare. We would also like to sell hot beverages such as tea and coffee.
How can we cheaply and easily heat water up for tea and coffee without access to a power socket?
Best Answer
Do as others do and use a camping stove.
They come as gas stoves like this one or even as wood- or charcoal-fired versions (see here). Perhaps an avid camper among your friends could even lend you one, means you'd only have to buy the fuel.
But before you do this check with the local authorities / people responsible for the event whether they are ok with these open-flame stoves at a public event, keep a fire extinguisher ready and ensure noone can accidentally get hurt, especially if lots of people are attending. Ensure the stove is set up properly and on solid ground, not wobbly or uneven. Be careful not to burn yourself or your partner, especially if business gets hectic. You'll also need the corresponding equipment, e.g. a stovetop kettle, a hand-filter or french press for the coffee, and fresh clean water (unless available on-site).

Answer 2
You need a Thermette (Kelly Kettle or Storm Kettle in North America - they're all brand names). This would match the vintage theme.
Larger ones have taps near the base, and can boil 10 cups of tea in a few minutes.
These were coveted by construction and rail road worker gangs, as they could have a 10 minute break for a cup of tea and a biscuit (cookie in North America), including the time to boil the water.
Answer 3
Use a Vacuum Flask
An every-day thermos is not big enough for this task, but food service professionals have provided hot coffee and tea with larger purpose built containers.
Background
In China boiling water is often put in large (maybe about 3 liters) vacuum flasks. These are used at tea conventions, on trains, and at roadside stops. The water stays very hot and makes fine tea and instant noodles.
Selection
The following images show a couple of the smaller containers suitable for this task. Each of these are about the same capacity. The one on the right is similar to coffee dispensers at bagel or breakfast shops. It has a lever that can dispense the liquid inside.
