Yeah so, I admit, my coffee maker doesn’t look like this but if there were a power outage we’d all be wishing we had such a simple set up, wouldn’t we? Highwave’s Fresh Brew might be worth checking out for the very reason. I supposed you could attempt to hold the filters over a cup yourself, but if you do, let me know how that works out for you 
*note* my lovely boyfriend pointed out not everyone knows how to get hot water without power… I stand by my post and will assume your caveman/woman instincts would kick in and allow you to figure out how to get some hot water.
