@Bryan don't think you can assume the rain drops fall 2km w/o friction. Not sure what the terminal velocity of a raindrop is, but you really need to use that for calculating the KE of the raindrop. Too lazy to get my physics book out to calc the terminal velocity…

You left terminal velocity out of your equation.. your raindrops are a tad too powerful, if they were actually going that fast they would just tear through your umbrella huh

Cool gadget but the marketing sucks. If it's energy conscious, how can you put it next to a SUV? Did they not know now much gas it needs to move?

Surely that is the idea, to creat a contrast between the energy conscious umbrella held by the walking man and the high energy useage SUV.

I think that's kind of beside the point.

nah. it's called juxtaposition. i'm pretty sure you know that mean. just like i'm pretty sure marketers also know what that means.

oh yeah Hyundai Santa Fe, really thirsty. the thing uses the same amount of gas as a Camry.

Everyones a fuckin critic. Props to this design, and who cares if theres a god damn SUV behind it. The article is about the umbrella; not the SUV and its comparison to your head and how much of a negative impact they have on the world. Drop it like its hot.
