Making spent coffee grounds into charcoal for terra preta?
As other Hypographers might know, I'm a coffee addict. I drink a couple espressos a day, and this leads to a lot of spent coffee grounds. Usually I get a bag or two of them per week. Most of them have been going into my house plants or outside to feed the fruit trees, but I notice they can take a while to decompose. I also use them in potting soil mixes. I was wondering if I could do something more constructive and helpful with them...like making them into charcoal. Coffee grounds are already halfway there--they just need more roasting. Without burning my house down or making my neighbors call the police or fire department on me, are there any safe and relatively easy ways I could convert my coffee grounds into a small amount of charcoal? I can also get additional coffee grounds from my local Starbucks. I've been doing that recently for my gardening outside.
If I don't reply to this for a while, I apologize. Will be on vacation for a few weeks. I'll read and answer as soon as I get back.

That's NOTHING!!! I go through Four pounds of grounds (dry weight) a week AT HOME!!! That doesn't include at work, on the road and at resteraunts... Total daily consumption around 4 litres and change, If I'm home all day more!
Put 'em on foil and let em hang out in your broiler or put em on a microwave safe whatever and nuke em to char.

I think I would be shot into orbit if I drank that much coffee in one day.
Have you considered charring the grounds DD? If not, do you throw them in the garbage, or the yard?

Now That I've finally defeated a patch of back yard (I destroyed my plow and nearly killed my rototiller) I've been bagging them for mixing in to feed tastey goodies soon to be planted.(I wonder if my veggies will be caffinated)

Astronomical instruments needed to answer crucial questions, such as the search for Earth-like planets or the way the Universe expands, have come a step closer with the first demonstration at the telescope of a new calibration system for precise spectrographs. The method uses a Nobel Prize-winning technology called a 'laser frequency comb', and is published in this week's issue of Science. Read » | 0 comments
Stanford computer scientists have developed an artificial intelligence system that enables robotic helicopters to teach themselves to fly difficult stunts by watching other helicopters perform the same maneuvers. The result is an autonomous helicopter than can perform a complete airshow of complex tricks on its own. Read » | 0 comments
