Claim:
1. A method for moving one or more loads, in which method loads are moved along a channel on or in fluid, comprising: providing the channel extending substantially horizontally in a lengthwise direction, the channel having a cross-section in a plane perpendicular in relation to the substantially horizontal lengthwise direction of the channel, which cross-section defines an open section and a closed section in the same cross-section, wherein the fluid in the open section is directly in contact with surrounding air, and the fluid in the channel can flow from the open section to the closed section and vice versa through opening or openings located below a surface level of the fluid in the open section; moving the load or loads by floating load or loads at least partially inside the closed section; and creating partial vacuum or overpressure inside the closed section of the channel.
