Seriously? I had no idea LED lights could achieve such efficiency.

> Looks awesome, but what is the source of light in the centre?

Bryan has departed a bit from the design in the paper when it comes to
lighting (and internal decks). It looks to me like he's got sunlight
from the outside focused onto a diffuser that runs along the axis of the
cylinder. Or, perhaps it's artificial light. That's increasingly
practical these days, with the efficiency of LED lighting.

Best,
