In order to isolate the famous Staburags Cliff for inspection, engineer Jānis Jermancāns proposes to limit Daugava River with a concrete fold. Meanwhile, underwater archaeologist Voldemārs Rains plans to descend to the bottom of the river using an elevator with a transparent tunnel.

Technical Director of Latvijas lifts – Šindlers Victor Hmarnijs criticizes this idea. «It can only be done using a glass shaft that could fit a panorama elevator. I for one believe this idea to be too utopian, because this kind of elevator shaft that is dense enough to withstand so much pressure and is designed to be water proof is very complicated to manufacture. This idea should be discussed with builders and ask their opinion whether this project is possible to realize or not.»

A glass elevator and elevator shaft is nothing unreal in solid ground, many places employ this kind of elevators. But to make one work underwater, you would need a hermetic tunnel that can fit a panoramic elevator, because elevator systems are not waterproof. The elevator shaft will require special conditions to make sure the glass surface does not sweat over. One other fact should be taken into consideration – the water in Latvia’s rivers is dark, and it is hard to see anything as it is. Hmarnijs himself never saw technical solutions to these problems anywhere in the world. He is also convinced that the development of this system would be an extremely expensive project, Lativijas Avīze (Latvia’s newspaper) writes.

Štein lifti Project Lead Lauris Spičs adds, that «similar elevators are located in Dubai, in hotel swimming pools, with glass elevator shafts in the middle that have underwater elevators, so that visitors can look at the exotic fish swimming in the water.»

The construction of an elevator on Daugava could cost around 25 000 LVL, but the main expenses would, most likely, concern the construction of a hermetic, glass elevator shaft.
