TAS

This stock became almost valueless... but it owns a chunk of EDE.

Once EDE started to perform, TAS started to gain value.  I think now the child is so valuable that the parent has become meaningful!  However, because it has fallen so much, after accounting for inflation, I have to hope that EDE jumps another 100% before TAS becomes profitable after all these years!

Interestingly EDE has another technological project in India which has stalled.  It peels off the hydrogen from methane, and use it as Hythane to run an engine.  The leftover carbon is used to make the carbon nanofibre.  When hydrogen burns in oxygen, it becomes water.  However it is an extremely flammable gas...  explosive too if not controlled.
