My comment on:
"For
many years now, we have known that the material that makes a spider's web was
the strongest material known to humankind. However, now in the 21st century,
humankind has finally overtaken the spider, when s/he has produced the carbon
nanotube. This humankind's invention, together with that of the spiders, can be
used for conquering outer space and the great depths of our and other oceans.
The carbon nanotube is over 100 times stronger than the strength of the material
used to construct Britain's state-of-the art £2 billion nuclear submarine,
namely HMS Astute ("Pressure Vessels: External Pressure Technology" by Carl T F
Ross, Woodhead Publishers, Cambridge/Oxford, UK". Moreover, its density is
nearly 1/6th that of steel. Thus, the carbon nanotube can be used for conquering
the great depths of the Mariana Trench (7.16 miles/11.52 km), together with that
of the oceans of Jupiter's moon, namely Europa; where the latter's oceans are
about 60 miles/100 km deep! According to my calculation, if a submarine such as
HMS Astute, dived to the very bottom of the Mariana Trench, the total
hydrostatic load acting on it, will be equivalent to about the weight of 4
million unladen double-Decker London buses; where the unladen weight of a
typical London double-Decker bus is about 7 tonnes! Thus, these materials should
provide a step-input into humankind's technological advances and his'/her's
conquest of inner and outer space. Let me hastily
add, that if a large submarine pressure hull, of (say), internal diameter
10m/32ft, is designed in high-tensile steel, to dive to the bottom of the
Mariana Trench; its wall thickness will be about 2.3m/7.5ft; this vessel will
sink to the very bottom of the ocean and you will not be able to resurface it. I
have designed large submarines, in my above book, which can safely conquer the
Mariana Trench; see Chapter 11; on "Star Wars Under Water"! Also, if we can
conquer the 60mile/100km depths of the oceans of Europa, we may discover
extraterrestrial life down there. This may be likely, because Jupiter's moon Io,
which is near Europa, is volcanic; due to it being stretched and compressed by
the gravitational attraction of Jupiter, Europa & Ganymede;
thus as Io is volcanic; so to will Europa be. Thus, if Europa is volcanic, with
its very deep oceans, Europa is likely to have marine life; living off the
outputs of Europa's hydrothermal vents; see my video-lecture on this topic; on
YouTube (carltfross). My video-lecture lasts for about 50 minutes; so make sure
you have a large beverage drink with you, while you are watching my YouTube
video!!"
