Email of the day - on battery powered flight:

I loved Lex’s tongue-in-cheek view of lithium-on batteries. A useful energy density chart that shows where lithium-ion batteries are - roughly in between lead batteries and liquid hydrogen.

Eoin Treacy's view

Thank you for this story and I also enjoyed the tongue and cheek nature of the energy density comparisons. I suppose it is no longer politically correct to point out that whale blubber has about 87% the specific density of kerosene which is better than lithium ion batteries. If that could be artificially replicated, we really could see whales fly.
