Venus is such a facinating place.
I have often wondered if Venus ever harbored life. Perhaps billions of years ago before conditions on the planet literally went to hell.
However, it has been suggested that at the level of the cloud tops 30 km above the ground there could be "
prebiotic" conditons. According to
David Grinspoon in his book "Venus Revealed" the suns energy is being absorbed in a way that cannot be accounted for. Not only that, but the atmosphere in general are at a dis-equalibria (similar to Earth's with it's free oxygen). The conditions up there are almost earthlike temperature and pressure wise.
Conditions on the surface are so extreme, that the atmosphere there may not even be a gas. At a temperature of 460 C, and at 96 atmospheres carbon dioxide - which makes up more then 90% of the atmosphere - exists in a
supercritical fluid state (characteristics of both gas and liquid). Many substances could literally be dissolved in those kind of conditons.
A colleague of mine does research with supercritical fluid CO2. Currently, it is used for decaffinating coffe and removing petroleum contamination from soil.
