Bitcoin consumes 4,000,000,000 W of power to process four transactions per second. A single Raspberry Pi with a database can do an order of magnitude more on 5W. Think about that next time you wonder if it's a good design.

I'm a little confused about one thing. bitcoin doesn't *require* that power. you could run the block chain happily on a raspberry pi. that power is being put into bitcoin voluntarily. is there an alternative approach that does the same thing?
Bitcoin doesn't *require* the power, but it *does* have the 4/sec limit built in. So we're in a situation where that power is being put into a system voluntarily and we aren't getting any throughput improvement in return. That's the problem.

yes, the power isn't related to the throughput. No one claimed it was. It's related to something else.
-
Another way to put it, the problem of increasing the throughput (needed) is orthogonal to the problem of reducing power usage (also needed, with not much movement on it)
