Are these helium filled?

If so they should be banned.

Once we run out of helium - no more MRI scans as the helium is essential to their running.

I just wonder if you could run one of these with solar heat (solar concentrating cooker perhaps?)

Or have two skins on the balloon   the outer transparent the inner an absorber = heat the whole balon  Tongue

Or concentrated  sunlight through a fressel (?) lense ...... sure when its raining you need a waterturbine  Grin

Just a thought

Not sure what they are using helium for in the MRI - is it for cooling the magnets? Or the sensors? There are some more sustainable options - - interesting, that at the beginning of this article, it says something about finding an alternative to the 'rising costs and increasingly unreliable supply' of liquid helium.

I'd have thought you'd be in favour - you know where the man made helium sources are!
