cryptocurrency只會越來越難挖, 越來越耗電

挖礦搞到D顯示卡好貴
好似話要用ASIC挖, 否則用顯示卡挖的話電費系貴過挖出來的礦的價值
不過cryptocurrency個價系錦升, 上面果句應該只系曾經成立過

不過***已經研發左用於挖礦的ASIC, 應該會大幅優於中國生產的挖礦ASIC

電動單車

千餘元有交易

便靚正環保解決交通問題

在香港? 左又屌, 右又屌, 問點解唔監管, 點解要阻路
真正環保系最原始的人力單車
電動單車都系用電, 而且中國煤發電佔左大多數,好多汙染物,而且中國的發電廠發電效率比外國低
除非可以做到再生制動否則可能比燒汽油的"電單車"更加吾環保
而且仲有電池廢物問題
中國大力發展電動車,但電池回收業遠遠落後其他國家
電池用幾年就虧就要換,架車未壞電池就要換
過多幾年真系吾知中國D電動車電池會點

全世界挖礦挖得最多的國家系中國,
全世界超過三分二cryptocurrency系系中國挖出來
吾信就自己搵新聞
系連可再生能源的發電廠都挖埋一份
又或者私人同發電廠合作挖礦(電價特別平)
地方政府又可以增加稅收,即使中央政府會要壓制挖礦地方政府都系隻眼開隻眼閉

真正環保係用對腳黎行路,製造單車需要挖礦開採源料。廣東省主要電力來源來自核電廠,大陸嘅核發電技術已經去到第三代,前幾年英國政府仲請大陸去幫手興建核電廠,大陸已著手關閉好多煤廠,還有中國是用煤大國,生 ...
單車係類似體力消耗速度係行路三倍左右,平路來講,可以去到行路你唔會行的距離,例如你行要一個鐘單車只需20分鐘,已經可以去到好多地方,可以配合埋鐵路去做通勤。只要唔好好似某d地方d共享單車被整治的話單車可以用好多年。
中國仲有好多省份係倚重燃煤發電,我之前讀大專做過assignment,有看過學術論文大約兩三年前的論文。
同話過係中國倚重燃煤發電的省份例如北方果d電動車比普通汽車更加唔環保。
中國自產的煤係低質多雜質多水同重量的煤燒出來的能量更低汙染物更多,中國燃氣輪機技術係落後過外國,仲有效率高的發電廠投資係貴d,所以話中國發電效率低過外國。
電子廢物外國係會出口但好似好多都係電路板之類,而電動車會產生大量廢電池,個問題未殺到,但我之前搵的論文係話外國係電池回收技術研究係領先中國,中國係呢方面研究係少,仲有係驅動之家講電動車的新聞d人都係留言話電池問題而家極待解決,回收係要有技術可以合乎成本效益去做
