cement for current cars, which operate with solely on oil is essential. Hybrid cars and Hydrogen fueled cars would be alternatives for current cars.
3) Hybrid cars
Compared to Gasoline-Diesel cars, superiority of hybrid cars appears apparent. Gasoline-Diesel’s 18~23% of average efficiency energy means that most energy is lost with heat loss. Additionally, in case of driving in low speed, th
Figure 13 shows that cryo pump is cooling pump. It means this pump is cooling, liquefaction and store air, not pumping. Generally, it has 3 processes like condensation, absorption and trap at low temperature. The cooled air or molecules do not have any momentum so it is no possibility to heat any molecules. It means vacuum.
Cryo pump have High emission velocity and high emission capacity so it
Low Popularity of Underclothes
Here comes a problem—although underclothes offer a number of benefits and owns two evident merits- keeping warm and saving energy, the sales of underclothes is not so satisfying. So we need to see another point of the consumer market. According to the interview and questionnaire, it is not difficult to find that there is a common prejudice about wearing under
