hello world and best wishes hyperloop

Hi Folks:

Congratulation to Mr Musk to bring, not another new way of transport to this world (so many before are now in the trash bin), but a new one that, tweaking old technologies can be great, efficient & even feasible. Lets hope it reaches mature.

I`m civil engineer coming from the iron wheel&track system: old, reliable and always turning out to be the most efficient system of transport (not the cheapest however, as the track and platform has to be constructed at first)

Just thinking crazy, now that the child is young and stands for things like this:

At high speed design, aligment is main weapon to combat the enemy; orography, but is a very expensive weapon; you have to move or cross mountains to increase or get the desired speed.

I guess that nobody tired to fight with mountains & valleys has ever tried to lay tracks over the flat sea for obvious reasons, but consider Mr. Munsk system if you add water:

- Pipe is a sealed system with a big positive buoyancy in water when filled with gases.
- A floating duct braced to the seabead with cables, will keep its position whenever its dead and live loads together are lower than the buoyancy (Reaction from seabead can be gained wether from anchorage or ballast).
- With two or more cables the system can be made hiperstatic and centrifugal forces reacted.
- Live loads of hyperloop cars (and dead loads of pipe & cables) must be lower than the buoyancy of the free space between cars that is quite high in this transport in relation to the lenght of the vehicle .
- A submersed system can be kept flat in vertical aligment between surface and seabed, and horizontal radius will be very open, so centrifugal forces very low in all directions.
- Because of economy Mr Munsk system avoids vaccum inside. Even thought you can pump water, watertightness is probably here most tricky and a big problem even if you don´t go too deep (30-50m) avoiding sea surface risks. Probably a two chambers pipe will be requiered and a lot of risk analysis taken to avoid drowned passangers or Hyperloop pipe sunk in the bottom of the ocean (only expensive floating composite lightweight materials could avoid the last).

Due to the last point (and messing the sea with cables) I guess we won´t ever see a Hyperloopsubmarine joining continents (what a pity, planes & oil will stay for long) but it was worth a think. Maybe dolphins can improve their transport chances in the future with this.

Good as a physics problem at all. Is like turning down an arch to work as a catenary.

Another physics issues will rise as cable stiffness and elongation (specially with long cables) will make stationary waves from currents and others move the pipe like a snake, maybe no hazardly but probably enought to make high speed passangers very seasick.

So, as Garfunkel sang:

"Tom, get your plane (or Space-X) right on time".

In fact there are other solution for developed a system hyperloop transport, most efficient, low cost fast production in series for developed this project.
1. Turbine electric with reactor of transference of mass for recharge the battery litium nikel, low cost
2.this turbine electric funtion in tube hyperloop system vaccum, first reduce the diameter the tube for example 1.25 mts, fast production the tubes and low cost the system vaccum
3. The POD, aerial running over rail system electro magnetic dynamic estructure in rail aluminium and new aleation superconductive this solution reduce low cost.
3.1. The desing of the POD production in escale control in factory according the standart of safe transport under press vaccum tech interior hermetic, control climate interior, more passengers, class VIP, toilet, bed for rest auxiliar in case emergency medical or care, room service,azaffata, pilot commander, and other innovations elevator neumatic inside, etc.command tactil instruments, panel control.
4. System Neumatic for transport Container in tube independent, complete infra estructure, management to containers standart,
5. The design line Hyperloop transport are lineal, not curves, according regulation of secure transport passengers.
5.1. The limit 420 km pour hour according the regulation international for transport passengers, not passengers Hypertension and medical care.
5.2. The reason indiscutible THE EFFECT JUMP, if stop abrupt all passengers LOST THE LIVE,
