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.

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?

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

"as a fuel" or "to generate electricity"?? Kind of weird...

核聚變之中, 會產生能量. 而d 能量會變成d 乜, 就睇下科技發展同人類究竟需要d 乜喇.
講多少少啦, 希望大家都聽過 E=mc2 呢條偉大又有簡單既equation. 基本上, 物質同能量係可以互換, 核聚變就係由mass 變做energy 既efficient 例子. 話唔定, 科學家將來可以發明一個device, 可以將任何物質轉化為能量, 不過唔知到時成個宇宙會唔會比呢個device "吸"左呢?

你自己伸手探飽佢, 仲可以採礦啦!

作者: soli 時間: 2010-10-6 19:49

問題係要點收集釋出黎既能量。
核聚變要超高溫﹐仲要響真空環境下製造﹐唔係就無法控制﹐所以就算做到energy input >output﹐都用唔到。
唔通用太陽能電池咩

如果人類用到核聚變黎發電﹐洗鬼要月球D咩同位數﹐地球自己大把。

小弟有一個信念, 而家諗唔到做唔到既野, 隨住科技發展, 將來有機會達到的!
當然, 我應該唔會有咁長命等到, 但我既子孫, 佢地既子孫, 同埋果陣時既人都有機會享受到呢d 成果架~

not really... your 子孫 not necessarily have any 子孫 at all... maybe one of them is gay/lesbian, your family tree will be died there...

冇問題~ 咁改成"大家"既子孫就得啦!
