evidence: Advanced steam technology -LRB- sometimes known as Modern Steam -RRB- reflects an approach to the technical development of the steam engine intended for a wider variety of applications than has recently been the case .. steam engine. steam engine. Particular attention has been given to endemic problems that led to the demise of steam power in small - to medium-scale commercial applications  : excessive pollution , maintenance costs , labour-intensive operation , low power / weight ratio , and low overall thermal efficiency ; where steam power has generally now been superseded by the internal combustion engine or by electrical power drawn from an electrical grid .. internal combustion engine. internal combustion engine. electrical grid. electrical grid. The only steam installations that are in widespread use are the highly efficient thermal power plants used for generating electricity on a large scale .. thermal power plants. thermal power plants. In contrast , the proposed steam engines may be for stationary , road , rail or marine use .
