Casuing climate change

"The Met Office will also use the machine for researching climate change."

Shouldn't that read...

The Met Office will also use the machine for _causing_ climate change.

How much power do you think this thing uses? And I bet it's on all day and all night, running its simulations.

40% efficient

From the BBC article on the same...

"Measurements showed that the setup could transfer energy with 40% efficiency across the gap."

They'll need to do a lot better than that in today's "green" age. (I know that some end devices, such as incandescent bulbs, are very inefficient. Even so, we can't afford to throw away another 60% on the path from energy source to energy use.)
