The transportation system described here,
it can maximally diminish energy losses, while moving with high speed.
The train runs in the vacuumed tube down to
0.1 atm., so its lift-to-drag ratio can boost up to 2000:1, and aerodynamic losses
of the train of 200 ton are lowered to negligible 1000 N at 450 km/h being now
practical one, or about 4.0 kN for 900 km/h of mine, needs the power of 1,000
kW being 150 times better than Boeing 787 Dreamliner, and can run as for middle
range and for long range with middle range stops.
All carriages are equipped by two small
plates like a kite each, can take to down the said train load on the said rails
and on the tube bottom to negligible load, even if it being no load, but flying
like birds above the rails 8-)) up to a meeting the God. At reasonable cases,
the friction force and energy losses of them would be practically zero.
The said tube of steel would be no more
than USD 100,000 -150,000 per kilometer, and only its bottom have to be reinforced
to bear rails and the train’s total weight. It is hundred times cheaper and
incredible simpler than Maglev system, and 1.2-2.0 times quicker of them.
