Nerissa Gliders is a wonder machine, with superior advantages over trains and aeroplanes. It can travel faster than any one of them at a lot lot lower cost. For example it doesn't cost a fraction of the cost of magnetic trains, maglev trains, to build and run. You need very high expensive capital skills and huge investments to build and run maglev trains and only very rich nations can afford it. On the other hand you can train any one quickly to create an inexpensive capital skill to build and run Nerissa Gliders, which any nation can afford.
Besides, it is green and environmental with almost negligible wear and tear costs. The gliders don't have any major moving parts fixed to them to become a heavy load to cost fuel and cause wear and tears. The engine, the fuel, the wheels, the gear box and any other associated parts are fixed separate from it externally, if any one of them needed. If the glider entirely depends on the gravity to move, even it doesn't need an external engine and fuel, and if it is gravity-operated it can recover and reuse its gross weight potential energy to become almost free fuel cost-operated.
As a wonder machine, it is up to you how to exploit it. You can build it to operate on a slope by gravity to minimise or possibly to eliminate fuel costs or drive it against a slope or on an even level route. In each case, it is going to be a lot cheaper than other means of transportations to build and run. On the other hand, you can build it for entertainment as roller coaster to thrill more than any other roller coasters can do in the world. You can build it like small trains to amuse children at amusement parks.
Nerissa Gliders can be built with important aerodynamic advantages over aeroplanes and fast trains like bullet or maglev trains. Aeroplanes and fast trains need air help to move. Fast trains need aerodynamic designs to press the train against the rails to get a good traction. Aeroplanes need aerodynamic designs to help aeroplanes to fly. But all these designs obstacle the speed and cost more fuel and wear and tears. On the other hand, aerodynamic designs of Nerissa gliders made to get rid of air resistance as an obstacle to speed and to reduce wear and tears.
Gliders of Nerissa Gliders can be made like a cylinder in the middle with long cones at the back and front. This creates an aerodynamic shape, which makes air resistance almost negligible and could make Nerissa Gliders to cross terminal velocity or at least obtain very high terminal velocity. The wheels are not fixed to the gliders. They are fixed on the ground for the gliders to pass over them. To minimise wear and tears on the wheels, the gliders can include aerodynamic shapes to give them a bit of lift to minimise thrust on the wheels. This doesn't cause traction problem because the feet of gliders can be sandwiched between two driving wheels, one under the feet and the other on the feet, pressing the feet against each other.
Let us to build Nerissa Gliders between Manchester and Liverpool to explore all options as an exaomple. Manchester is 125.00metres over sea level and Liverpool is 70.00metres over sea level. This makes Manchester higher by 125.00 – 70.00 = 55.00metres than Liverpool. The distance between both points is 52.00Km from centre to centre. One option is to build it a long existing railway lines. This option should reduce the cost of fuel and wear and tear caused by unloaded major components and it should reduce travel time. For an acceleration of 0.25m/s/s, it shouldn't take more than 15.00minutes.
Another option is to build a route along the existing railways but on an even level. In that case, we have to build the station in Liverpool 55.00metre high and outside the city. So passengers and cargoes in Liverpool have to go up 55.00metre, which have a fuel cost but this cost can be recovered. Because potential energies of the vehicles take up passengers and cargoes can be recovered and the potential energy of what ever comes from Manchester can be recovered. Because the gliders are travelling on an even level, they need a minimum amount of energy to run them. The potential energy of cargoes and passengers coming from Manchester could be quite more than enough to run the gliders on both directions. With a few windmills build a long the route, we should have energy enough to run the gliders at any weather conditions at their usual speed. This option could be more viable than any other options. On the other thought, because Liverpool is on the sea, where wind power always available, windmills can be build near the sea to supply power to Nerissa Gliders Shuttle between Manchester and Liverpool.
Alternatively, we can build it between both points to depend on gravity power entirely. This is assuming we can get a straight or nearly straight route between both points. The stations has to be built outside the cities with an assumption distance of 40.00km or 40,000.00metres between both points. To get a gradient or a slope sharp enough for gravity, we use a height of at least 200.00metres in Manchester. But in Liverpool, we use a height of 55.00metres to create an even level route from Liverpool to Manchester.
The Gliders from Liverpool to Manchester move on an even level route. So they don't need a lot of energy. Cargoes and passengers in Liverpool go up 55.00metres in vehicles this cost fuel and create CO2 over 55.00metres. But potential energy of vehicles going up can be recovered, when they come down, and stored for reuse later. In Manchester, cargoes and passengers have to go up 200.00metres, which cost fuel and create CO2. But potential energy of vehicles going up can be recovered, when they come down, and stored for reuse later.
The gross weight potential energy of gliders from Manchester to Liverpool can be recovered and stored for reuse later. Potential energy of cargoes and passengers coming from Manchester can be recovered at Liverpool station whey they descent 55.00metres. The total energy recovered and stored should be more than enough to drive gliders from Liverpool to Manchester and lift up them 200.00metre in Manchester.
In this system, we operate a transportation system between Manchester and Liverpool possibly without any external energy input and with a negligible CO2 production. CO2 produced only on a route of 255.00metres, 200.00metre in Manchester and 55.00metre in Liverpool. But we eliminated CO2 production on 80,000metre route, 40,00.00metre per direction.
