hybrid 的 prius 有 從煞車回收能源 但是 hybrid 系統複雜 使用 240v 電力 ..那有沒有車商開發簡單的節能車
直接使用煞車能量 或是 引擎的熱力 來 提供車內電力 ..雖然不如 hybrid 省
但是 至少也該有幫助 . 因為 都有人拿引擎熱來烤地瓜 , 這個熱 白白的浪費掉 好像很可惜
Honda FCX Clarity: hydrogen-powered automobile
Many think the infrastructure for a hydrogen-powered car just isn’t there, and they’re mostly right. There have been a few advances in hydrogen production recently, but the distribution system is the weak point. Honda won’t let that deter the production of a hydrogen fueled car, though. The FCX, which gains the name Clarity in production trim, debuted today at the Los Angeles Auto Show.
The fuel-cell powered car will go into production and be available for lease around mid-year 2008. Leasing is will be limited initially. Now word yet on total costs, but montly payments are expected to run around $600, which includes insurance and maintenance. Southern California gets first dibs on the program.
Fuel economy is rated at the equivalent of 68mpg from its 5,000psi hydrogen tank, giving the FCX Clarity a range of 270mi between fill-ups. That range is an increase of 30 percent over the concept, thanks to a 400lb diet in the powertrain. Further weight loss improves the power-to-weight ratio by 25 percent. The size of the powertrain has also been reduced by 45 percent, and is now about the same size as a gas-electric hybrid powertrain.
The FCX Clarity is not just a drivetrain technology showpiece - it boasts some pretty unique materials in other areas as well. The seat upholstery and door linings are made from ‘Honda Bio-Fabric,’ a material made from plants. The interior is also chock-full of just about every feature you can think of, from airbags to Bluetooth, from sat-nav to climate control.
Because consumers adopting the FCX Clarity in this limited test-run are certainly going to be environmentally conscious, Honda has taken special care to reduce CO2 emissions from all sources - from production to end-user. Although the FCX Clarity’s only local emission is water from the burning hydrogen, the process of creating the hydrogen from natural gas does create some CO2. The amount created translates to approximately half that of a petrol-powered vehicle, given equal use. Hyrdrogen from other sources, such as water electrolysis, can be even cleaner.

這個想法實現的機會有可能，但是實際應用會有一定的難度。
第一點，能源儲存了以後要如何應用?如果只有單純使用引擎的話，那把動力回收以後，要如何把動能儲存再回饋給引擎?以前有看過幾種想法，一種是把車輛多餘的動力儲存在類似小時候玩的迴力車結構，另一種是轉換成壓縮氣體，然後藉由壓力釋放再度變成動能，但這種系統應該是滿簡單的，但要能運用得好，而且不會改變原來使用車的方式，可能有一定難度。
第二點，熱能如何轉換?現在最有效率的熱能運用，應該是火力發電，把熱拿去使水沸騰，然後水蒸氣驅動風扇，然後把風扇的動力轉成電能，在車上弄個類似的系統應該不難，只是變成電以後，要拿去幹嘛?如果只能來驅動音響及車上必須的電力供應，系統的設計可能比用原來的系統更貴。
hybrid目前轉換的功能大概是目前可以運用的最好範例了，將多餘的動力轉換成電力，電力拿去驅動馬達又變成動能，引擎的每一匹馬力都用在讓車輛前進，任何時候有多餘的動能都轉換成電能儲存。而且從目前PRIUS的價格來看，我不認為HYBRID的系統會複雜到哪裡去。
