環保局可否要求拆走部巴士冷氣，
來行走郊區流水路線，如64k及77k來達到能源節省效果？
因為部巴士係政府資 ...

你既建議咁有建設性，點解唔返政府工而要o係度刷存在感

混能多舊電，本身重左，跑高速用油
但好似南區線柴斜線本身有市區流水功能（或一少段長途）的路線，係可以 ...

之前本身都同朋友傾過, 混能規格有得儲能源, Eco引擎
最應該係派流水爬山線, 例如 90B, 91, 8X/19, 82 呢類簡直係有齊呢類特點
結論同你講差唔多

派 5B, 8, 969 當然可以係巴士公司同署方決定,
公路線派係無問題, 當係試下,
但我覺得其實當局應該深思下邊D線最適合

如果係全數資助，點解九巴做得咁慢？

九巴車輛加裝SCR系統消息

呢度講個原因好明顯

其實混能只係以前純電動車技術未成熟時嘅產物
當電動私家車都做到好高續導力，電動10米雙層都試驗緊
再加上 ...

反而我覺得用番柴油,但係12.8M 咁大個範圍加太陽能板仲慳

根據英國 E400H 經驗，舊電池應該用唔到十年，
一個方法係換電池黎延續壽命，不過成本會較高，
另外英國 ...

Converting hybrid back to conventional power remains a rarity in the UK, and that only happened to Optare products which are notoriously unrealiable.
As for the E400H (and indeed B5LH and NRM), I will be amazed if they do anything other than replacing the battery packs when the time come. To replace the powertrain completely takes far too much effort, and costs too much for a bus that if well past the halfway point of service life, to make it worthwhile.

And as for the trial result itself, it is hardly surprising given how much hit the air-cond system takes out the efficiency. Having said that, this also affect pure electric buses in the same way. For this reason, I do think that the virtual electric concept i.e. hybrid bus with opportunity charging, like the B5LHC, has a lot more to go for. However, to make this work, it needs a very comprehensive planning to strategically place charging stations at locations where buses are likely to stand for a relatively long spell (3+ mins) to make the system works to its best efficiency. That said, I am skeptic to see this ever happen in HK.
