        <description><![CDATA[VACUFLOW  TechnologyThe vacuum sewerage system is a dry weather system which means that rain water may not be connected.   The VACUFLOW  System requires no use of so called inspection points. The most characteristic features of the VACUFLOW   Technology is the guaranteed simultaneous suction and transport of sewage and air through a closed pipe network under constant negative pressure and its highly sophisticated, empiric adjusted, friction and static loss calculations in pipe lines.In addition, the VACUFLOW  system is virtually maintenance and because it operates within a closed and leak proof vacuum system, the environment will benefit too. No sewage can escape to pollute surrounding areas.The vacuum system is perfect for a wide range of applications, particularly where expensive and tractate construction work is to be avoided. Think of areas under ground fill or shallow topsoil as well as areas with a high water table or where the environment is fragile.For more please contact : http://www.quavac.com]]></description>

        <description><![CDATA[While I think long distance travel is a nightmare with jets spewing their pollution at high levels. They should be looking at fixing the problem of Work Commuters, you want to talk about sucking fuel and pollution to move one person to work (in the West) and our antiquated Rail (in the east) They should be investing in systems like Skyweb Express by Taxi 2000 why aren't our powers to be investing in systems like this where you control your carbon output at a single source and move millions of people efficiently. People have many reasons for long distance travel, I feel that solution is the real vacuum of Space, Up then down at your destination. I think Virgin-Atlantic is at the forefront of this, he is playing with it now but the studies with propulsion are advancing quickly. Especially when they figure out Higgs-Boson, moving atoms through atoms without damage.]]></description>

        <description><![CDATA[Yes, you are right about acceleration. To reach 2500m/h in 120 sec. the acceleration is 9.31m/s*s. When up tospeed, the train has crossed 41.66 miles.However the distance from London to NY is 3475 miles. Obviously you cannot cover this distance in 56 minutes at 2500m/h. Right ?Jacques]]></description>

In 56 minutes you cross only 2333 miles at 2500m/hTo reach the speed of 2500 m/h in 2 minutes, the acceleration should be in the range of 1117m/s??, that is 113 times the earth acceleration.

        <description><![CDATA[With ET3, small access portals are distributed along the tubes like exits on a freeway.  It is said that 90% of Americans reside within 15 minutes of a Walmart store.  A typical international airport serves a population of about 5 million people.  100 ET3 access portals can be economically distributed over the same 5 million population for one access portal for 50k people (about like the frequency of Walmart stores).  A typical American is more than an hour from an airport, and the last airport built in the US was DIA at a cost of $4.8B $4.8B could build as much as 1600 miles of double tube ET3 system with a 400mph design speed-- serving a larger area than the typical airport.]]></description>

        <link><![CDATA[http://www.smartplanet.com/forum/discussions/1-10702-72833]]></link>
        <description><![CDATA[This article is poorly researched; ET3 is NOT a train (or vactrain).  The article also improperly uses ET3 artwork to illustrate the work of others.The focus of ET3 is on travel over distances of 200 to 600 miles.  Only if all nations build ET3 to the same standard can it be networked together with a backbone built across the Bering Strait.  ET3 does not advocate deep water tubes to cross oceans.  We suggest reading et3.com and et3.net and also look up US patent 5,960,543 BEFORE making comments about what ET3 is NOT.A maglev train costs about 20% more than conventional HSR (high speed rail), and a &quot;vactrain&quot; (like swissmetro for instance) costs about three times more than a maglev train.  ET3 by contrast costs less than 1/10th as much as conventional HSR, 1/13th the cost of maglev trains, and 1/35th the cost of a vactrain.]]></description>

        <link><![CDATA[http://www.smartplanet.com/forum/discussions/1-10702-72829]]></link>
        <description><![CDATA[You are correct the US passenger rail is pathetic compared with Europe and Asia rail.  And this is one reason the US economy is more favorable (witness the lower CPI, and greater GDP).  The US has waisted less than $40B on train subsidy, while EU and Asia spend far more per passenger to subsidize train passengers.Passenger trains in the US carried over 90% of intercity travel in 1910, now they carry less than 2%.  In spite of much greater government subsidy for passenger trains in Europe and Asia, rails market share continues to shrink.  Cars now are over 70% of passenger miles in EU, and 60% in Japan in spite of the governments spending over 50 times more per passenger mile for train travel than for road and air travel.  Private industry requires positive ROI (return on investment) to survive.  Negative ROI is why passenger rail systems are not privately funded, built, and owned .(as they where 150 years ago when they offered better value than the alternative -- muscle power).  Government pays 100% of the construction cost, 100% of the vehicle cost, and typically from 1/3 to 2/3rds of the operating expense.  The ONLY HSR (high speed rail) in the world recovering more than 100% of it's operating expense is in Japan (and this is only because the government wrote off 100s of billions in debt, AND punishes car owners with 100% vehicle tax, and 300% fuel tax and road tolls that recover more than the road cost (and still cars gain market share in Japan too).The fact is that passenger trains only survive due to gross government subsidy, AND oppressive fees on cars, roads, and air travel.ET3 offers much greater value than ships, trains, cars and jets for about 90% of passenger and cargo transportation. For this reason ET3 will displace cars and aircraft just as cars and jets have displaced passenger trains.]]></description>
