One thing they are really handy for is wiping the platters.

Are you sure about that? How much more energy is it going to take to make these? If it's more, then where is that energy coming from? Are the raw materials heavier to transport than the current ones? What waste by-products are produced in doing this? What can be done with those by-products?
I would like to see authoritative comment on the overall origin-to-disposal/degradation atmospheric carbon budget of biomass-based vs petroleum-based PET. The energy budget is related, but mainly as it affects atmospheric CO2.
Superficially, the burial of biomass-based non-biodegradable plastic looks rather like atmospheric carbon capture and sequestration. An environmental plus. Biodegradability is a two-edged sword. It removes junk from the environment at the expense of releasing carbon to the atmosphere.
Parent is right, you need ALL of the figures before making a judgment. Maybe I missed a trick.
The camel endorses your viewpoint.
I don't think they chose a very good camera angle for showing off the concept.
Agreed. The wing and tailplane look to be a continuous loop, too, which is not immediately obvious (to me, anyway)
Says it all, no?
