До меня окончательно дошло, что это прикол, только когда я дочитал до забора воды из облаков.

А вот это, вроде, на полном серьезе пытались построить:

Messerschmitt Me 264 "Amerika Bomber" - Page 2 - The Great Planes and warbirds Community:

The actual accomplishments of the Kommando [Sonderkommando Nebel - Special Detachment Nebel] remain unclear, but n August 1944, it ispossible that it commisioned Professor Losel of the firm Osermaschinen GmbH to carry out the design and development of a steam turbine power unit which was to be rated at 6,000hp at 6,000rpm with a power to weight of 0.7 kg/hp and a consumption of 190 grams/hp/hour. An Me 264 airframe - possibly the V2 - was to have been placedat the disposal of the firm, but itwas apparently destroyed in an air raid before experiments got under way.

Two forms or propellor were envisioned; one at 5.3m diameter revolving at 400-500 rpm and the other at 1.98m diameter revolving at 6,000 rpm.

The system consisted of four capiliary tube boilers, each one metre in diameter in 1.2m high; a boiler feed waer pump and auxiliary turbine; a main turbine, 0.6m in diameter and 1.82m in length; a combustion ar draught fan, condeser, controls and auxiliaries. By the end of the war, many of these components had been manufactured and were ready for use including one of the boilers, the turbine blades and auxiliaries, such as the combustion air draught fan and condenser pump. Work had also started on the auxiliary and main turbine.

The system was designed to use 65% solid fuel (pulverised coal) and 35% liquid fuel (petrol), but it was intended to use liquid fuel only when it became available in quantity. Osermaschinen claimed that the advantages of steam turbine power were:

Constant power at varying heights
Capacity for 100 per cent overloading, even for long periods
Full steam power obtained withing 5-10 seconds
Notsensative to low temperatures
Long lif and simple servicing requirements
Simple and quick control

The system lent itself to incorporation within an airframe, since it could be broken down into separate components.
