探月與生活息息相關 education, published, relating, article, little

After a few rounds of education, I guess those morons (KingKong, Lik and Sheep) may have learned how to look at China relating issue objectively.

This is a paragraph of an article published on 溫哥華星島日報 three days ago. Even though it only mentions small part of the SIGNIFICANCE of developing space technologies, it is enough for the morons to have a little understading of it.

探月與生活息息相關

月亮離地球有38萬公里。人們為何花這麼大力氣去探測月球？除了科學意義外，探月工程與民眾的日常生活有些甚麼關係呢？
專家指出，探月工程實際上與每個人的生活都息息相關。美國領先於世界的資訊、生物、新材料等高技術，很大部分來自對「阿波羅」工程技術的消化、優化和二次開發。我國探月工程所帶動的基礎科學和高新技術的進步，也會對經濟發展發揮牽引和推動作用。
同時，月球上特有的能源和礦產也是對地球資源的重要補充和儲備。氦的同位素氦-3能在核聚變反應中釋放巨大能量，且幾乎不產生放射性污染，被認為人類社會的完美能源。月球上就存在大量的氦-3，據估算，月球上蘊藏的氦-3大約為100萬噸到500萬噸，可供人類使用一萬年以上。

核聚變乜唔係用氫既同位素去做架咩? 當年話可以由海水既抽取氫既同位素去用作核聚變既elements 啊!
死喇, 我太outdate 了, 乜而家興用氦-3 架?... 科技果然日新月異, 十年前既知識已經過時了...

而且用得果1萬年實在太少了, 可能要向其他方面既能源source 打主意了. 其實太陽能都幾好用, 因為一日有太陽, 一日都可以有電丫麻.

核聚變?

Yes, the technology advancement nowadays develops at the pace that might very well beyond our expectation. The further China lags behind other countries technologically, it will be more difficult and costly for China to catch up.

Experts have predicted that for the foreseeable future, countries around the world will be divided into two groups – “with space technologies” and “without space technologies”. Countries that do not posses space technologies may very well have to become an ally of a country with space technologies. 講得衰Ｄ直白Ｄ－就是變成其他國家的小附屬國。

Will Chinese people want to become an “ally” of another country?

Haha, sounds like Gundam 00.

The only thing I don't agree is that, I don't think we will be able to extract significant utility from space in the 'foreseeable' future. Not at the current rate of investment and breakthroughs.

Exploration had been essential to the development of the Human Civilization as we know it. Without a doubt we need it for the long term sustainability of the human species. I don't see the need to justify exploration on the grounds of any immediate returns. Any short term benefits/utility we get from exploring space is just icing on the cake.

I think Helium-3 is just theoretical at this point. I mean, I don't think we got a net energy positive fusion reaction going yet. Any fusion talk is just theoretical.

Trust me, it will become a major source of energy in near future!

use it as fuel or to generate electric?

回復 8# mcjohnjohn

It will ultimately, but I don't think most LYK will live that LONG including myself....
