- 10 year ET3 update: - 1 Update
Daryl Oster <daryl...@gmail.com>: Jun 14 05:48AM -0600
It has been about a decade since I last posted to this group. A quick
search of the archives indicate there is much imagination about ET3 tech,
and happenings, however with very little apparent research or understanding
from a few of those who occasionally attempt to elucidate on the subject
in this forum.
Some commonly repeated erroneous guesses, misconceptions, (or lies) about
ET3 include:
* "The cost to maintain the vacuum is too high, therefore any advantages
are eliminated or marginalized."
[LIGO is evacuated to a thousand times higher quality of vacuum than
required for ET3, yet in spite of having over 50miles of welds, had no
measurable leaks in 2 years WITHOUT THE PUMPS RUNNING! Also, leak-proof
seals (even dynamic seals) are known that have no measurable leaks.
Finally, by design, the per cycle air to evacuate from a typical ET3
airlock can be made to be less than one liter. See the attached paper with
more evidence on this vacuum energy issue, and every other significant
other energy issue associated with ET3 ]
** "The tube material can't last, or stand the negative pressure associated
with the required vacuum pressure without collapse risk, or if made to
withstand the pressure are too heavy or costly."
[Submarine and/or underground pipelines often encounter net external
pressure, especially water and sewer pipes that go over hills or valleys
higher/deeper than 33 feet subject to a pump being shut off or power
failure. (many such pipelines are much larger than ET3). Also note that
properly sized and placed stiffening rings dramatically increase the
tendency to buckle, but only have a small increase in material use
compared to simply making the tubes thicker.]
*** "The system is too vurnurable to terrorist atack or damage from natural
forces."
[ not even close to the terrorist risks of cars/ bridges,
aircraft/airports, and ships/harbors, yet terror and 'acts of god'
represents less than 1% of transportation related fatalities. The UHPC
that ET3 can be most economically made from is likely to last for thousands
of years in full weather exposure, and longer if in tunnels. ]
**** "ET3 is too big ... or ... too small to meet market needs."
[Cars have won the transportation market, and ET3 capsules are designed to
match or exceed the cargo and passenger load utility of: cars/SUVs/pickups
(and do so at minimal cost).]
***** "People will feel too claustrophobic for ET3 to succeed."
[ The prevalence of cars, and elevators prove this to be false, however
phone booths have failed in the market! Stats prove that a higher % of the
population are unreasonably afraid of large groups of people, and/or open
spaces.]
****** "Too much time to load / unload ET3 capsules."
[ An airlock cycle time of 26 seconds is a fairly close match to the 15sec
to 20sec dwell time to load/unload a typical conveyor style amusement ride.
The ET3 trip time overhead of about 1 minute compares favorably with the
amount of time to park a car, start the engine of a car, or strap on a
helmet to ride a bike.
etc. ...
And, I also see that several friends have at least attempted to correct
some of the misconceptions about ET3, for such friends, I remain thankful.
If any of you have an interest in more information about ET3 progress over
the last decade, call or contact me at et3 [at] et3.com. Only a little of
ET3 progress is posted on the various ET3 websites, or social media pages
(hypeloop guys 'borrow' as if they originated the work, and without
attribution). ET3 Global Alliance is now over 400 licensees in 26
nations, and several projects have been successfully built and tested by
licensees, a few have been publicized by the project owners to a limited
extent.

Hi Daryl,
How is breathing air supplied to ET3 capsules? You've undoubtedly answered this somewhere over the years, but if so I definitely can't recall the answer.
