Scale-model testing is used with very large pumps such as water feed pumps for thermal power stations. The problems posed by such tests in establishing the full-size machine performance are well discussed in a paper contributed by workers studying pumps for the Central Electricity Board . 

According to the main idea, the autonomous wind-hydrogen station (AWHS) should be adapted to the conditions when a single consumer of the produced electric power is an electrolyser, which does not require standard stable parameters of power supply for its normal operation. To realise this idea, two main problems have to be addressed in the course of the development of the AWHS. 

The increase of CO2 in the atmosphere has been considered to be one of the causes of global warming. The amount of CO2 exhausted from the thermal power stations of electric power companies has reached approximately one fourth of the total amount of CO2 exhausted in Japan. Therefore, as one of the measures to cope with this problem, technologies to fix CO2 using the photosynthetic ability of the microalga have been studied [2], The establishment of the utilization technology of CO2 which is fixed by microalga is also... 

The removal of NOx emissions from stationary electricity generating stations is a far more tractable problem than NOx removal from mobile combustion power sources. There are two reasons for this.
