Freshwater scarcity is a global crisis due to limited accessible freshwater resources and rising demand. Seawater desalination is a key solution but is energy-intensive and reliant on fossil fuels, leading to high costs and environmental impacts. This study aims to investigate the use of solar thermal energy from an evacuated tube collector for freshwater production via evaporation and condensation. The focus is on analyzing system efficiency by comparing freshwater yield with energy input. The findings may contribute to the development of sustainable desalination technologies suitable for freshwater-scarce regions.
ปัจจุบันโลกปกคลุมด้วยน้ำถึง 70% ของพื้นที่ทั้งหมด แต่มีทรัพยากรน้ำที่เป็นน้ำจืด (fresh water) ที่สามารถใช้อุปโภค บริโภคได้เพียง 3% ประกอบกับจำนวนประชากรที่เพิ่มสูงขึ้นอย่างต่อเนื่อง จึงเกิดวิกฤตการขาดแคลนน้ำ การแยกเกลือออกจากน้ำทะเลเป็นแนวทางสำคัญในการแก้ไขปัญหานี้ โดยงานวิจัยของเรามุ่งพัฒนาเทคโนโลยีแยกเกลือออกจากน้ำทะเลโดยใช้พลังงานแสงอาทิตย์ ผ่านระบบท่อสุญญากาศ (ETSC) เพื่อลดต้นทุน พึ่งพาพลังงานสะอาด และเพิ่มประสิทธิภาพการผลิตน้ำจืด โดยเฉพาะในพื้นที่แห้งแล้งที่ขาดแคลนน้ำ

In the world of blood donation, there are 2 types of people: those who donate blood and those who don't. Most campaigners emphasize how to persuade more people to donate blood and recruit more new blood donors. We believe that even though such focus is important, there're more critical aspects that might have been neglected, which is: for those who have already made up their minds to be blood doners, will they be successful in donating when the time comes? According to our studies, only 63 % of attempted doners are successful. Regrettably, 37 % has to go home disappointed as their bodies are not fit for the conditions required by Red Cross medical staff at blood donation centers (which include some most basic preparations such as low-fat food intake and 8-hours sleep on the night before). Our campaign, ‘Blood in Need, Buddy Indeed’, focuses on 2 aspects. Firstly, to persuade more people to donate blood. Secondly, for those who have made up their minds to donate blood, we will provide necessary support (both body and mind) so that they are fully prepared and successful in donating blood when the time comes via networks of systems, staffs and the newly designed and prototype of the application ‘Blood D’. Our campaign covers the whole ‘before/during/after’ experience of users (as blood doners). Support includes assessment of their current condition whether they are within the requirement of Red Cross Blood Bank. ‘Blood D’ will also provide relevant information on blood donating events, such as locations, and time booking. Once sign-up, the application “Blood D” will sent friendly reminder and clear infographic on how to prepare their bodies as daily notifications during the 7 days countdown. This is to ensure that the users’ blood will be ‘D’ (homophone of the Thai word ‘ดี’ which mean ‘good’ and at the same time playing on the word ‘ Buddy’) or be the ‘good blood’ that can save lives for those in need. After organizing 4 blood donation events both within and outside the KMITL. The numbers of successful blood doners have increased from 63 % to 78 % (this number is the average of 4 events, with the most successful event of 89%). The campaign has won the first runner up in national blood donation campaign competition. It is highly anticipated that once the application “Blood D” is fully launched, it will help increase the amount of blood collected up to 15% with the same numbers of existing doners.

This project is a carbon safe haven of Bangkok, aspiring to be the prototypal gateway of the future's carbon net zero ambitions. The project aims to answer the fundamental "flaw" of the existing urban fabric, still being extremely inefficient and highly polluting. Conversely, Carbon Oasis would not only create its own energy, but look to provide its excess energy and water surplus' back to the city and its surroundings. Taking parts of the existing city and implementing new concepts to inspire a change in the urban fabric and its people.
