Greetings all,

The last time I asked the forums for advice that was related to my entrepreneurship endeavors, it was a few years ago, and the GC community was a big help.

I'm in a bit of a pickle, sort of. I have a business idea of offering a coffee service by my city's light rail stations (250,000 passengers per day). The whole idea comes from the fact that line ups at Tim Hortons, Second Cup, and Starbucks are too long, and rather a little expensive. My vision is to create a quick, easy, efficient, and cheap method of mass producing coffee so that people who are on their way to the train, or waiting for one, can quickly pick up a $1 cup of coffee.

Where the pickle comes in is that I want to save money on energy cost (and be green), as well as I want the business to be adaptable and mobile. I need a way to make hot coffee without energy. The alternative I am thinking of is possibly a modified propane burner that will heat up the water and then filter the the coffee through or what not. For the supply of water, that's a whole other issue, and I am looking for input on that as well. I am thinking of using spring water to make the coffee a little more 'fresh', rather than tap water most other places do.

Since GC is full of incredibly smart individuals, I figured we could put our heads together and tackle this obstacle!

What do you guys think?

Well...that was fun =)

Make the coffee nearby, and serve it via Coffee Babes™ and their travelling thermos bottles.

Thermos bottles rock.

btw, Coffee Babes™ is a trademark of Snaggy, as of this instant. [Razz]

How about the kind of coffee urns/brewers used on canteen trucks, aren't they propane and portable?

GameGod ________________________________ You actually have answered your own question.

1. Five gallon bottled water jugs, like used in watercoolers.

2. Propane fired water heater as used in motorhome and RV Campers.

3. Small trailer or cart that has the above and plenty of cups.

Gravity is your friend, the water will want to go down hill.

Look at how a Bunn unit works the cold water you pour in the top displaces the hot water that it just made or kept warm, thereby brewing the next pot.

Coffe bought on trains here come in two varieties. Premade coffee in coffee thermoses. This coffee is on the snack cart and is not very good. If the train has a restuarant car they have a dcent coffe maker (built in) and the coffe is good.


I would try to modify a nespresso, seaco, or jura automatic coffemaker to fit in a backpack type device. (or a frontpack if only one person works a train but I think you need two. The second person will wear a backpack with water, beans and other supllies.

a while ago, like 12 years ago, I remember seeing Starbucks selling coffee out in the streets with people carrying back-pack like thermoses, they looked happy and the sun was shining and people smiling. I think they were thinking the coffee was free tho, but they were charging for it (of course).

Not to be a spoil-sport, but I saw a documentary about coffee called "Black Gold", and as it turns out, coffee is baddie, the farmers that grow it are ripped off by the coffee corporations. Not to mention sun grown coffee and how it kills eco systems. I try to buy fair trade, bird friendly, shade grown coffee whenever possible. [Cool]

If you want something better than pre-made coffee from a thermos, try coffee plungers and a big thermos of very hot water.

If the staff are sufficiently babe-alicious, no-one will complain that you can't make real cappuccinos in a plunger.

You Vegans have something against everything [Razz]

I can make the argument that I would be buying coffee from a fair trade supplier, and also the argument is that it is actually good for you. Two cups off coffee in the morning combined with exercise prevents skin cancer.

So Ha!

Hate to nit pick but coffee is probably a cancer risk. It is because of the roasting of the beans. Most things that are burnt become cancer risks. The fire breaks apart stable molecules and releases all these free radicals that just want to bond with something, anything, and that turns out to be your DNA.

And don't let Nitrozac lord over you, organic no pesticide, loved for vegitables are shown to be more mutanagenic (cancer risk) than pesticide covered bio engineered vegitables. (via ames testing)

Numerous studies that find coffee prevents some cancers.

But just wait another month for the complete opposite report, as most of these studies end up being.

one cup of coffee (150 ml) was calculated to induce 3-4 × 106 AraR mutants. In contrast, coffee prepared from unroasted beans (green coffee) had no mutagenic activity. Regular- and sugar-roasted coffees showed similar mutagenicities, but the specific mutagenic activity of instant coffees (1559 AraR mutants/mg) was almost 2 times that of noninstant ones (834 AraR mutants/mg).

I'm sorry, I just can't believe that propane is necessarily more 'green' than electricity. I really don't think it would be more economic; where I live, electricity costs less per unit energy than does natural gas, and if I'm not much mistaken, propane.

Especially if you live in an area powered by a nuclear power plant. Think about it: The energy you would use to heat your water if you use electricity would produce essentially zero greenhouse gas emissions, ignoring what goes into mining. Even with the mining cost, you still come out ahead of a coal-fired power plant.


The only advantage I see to propane is that it's portable- you can set up anywhere you please and you'll be good to go. That could be very helpful in your situation.


How much power does a normal coffee-aparatus consume (I'm not a coffe nut (bean?), I don't really know what all goes into it)? You might could make a generator-bike and generate all your electricity that way. You'll get in shape, and it'll look cool!

Or you could set up a solar-brewer out in the sun, using mirrors and a black boiler to heat your water. Of course, this won't work every day, but it's probably the greenest way to go.

nerdwithnofriends __________________________ Depending on where one lives determines energy costs. Here in Michigan the state regulates Energy costs for Natural Gas, and Electricity, all other fuel costs are market driven. We live less than thirty miles from a series of hydro dams, however we still pay the same as the farthest out customers. That said a coffee maker uses a lot of electricity,

For GameGods purposes bottled propane would be the best choice for a mobile coffee stand, that could be taken to a train station. Brick and Morter stores Natural gas and or biofuel (weed pellets, not that kind of weed)

I have included link to a price calculator for some fuels.

Hi All ________________________________ Some of you are missing the point. There is no outlet to plug into, he wants to set up at the train station. So it is generator or propane. There are 12Volt cash registers and Credit card readers. Just the problem of boiling large quantities of water off batteries, not really feasable.
