關係子句

There's a heater that burns 80% less wood than your fireplace, keeps your home warm for 24 hours from a single 30 minute fire, and

有一種暖爐，比你的壁爐省下 80% 的木材，一次 30 分鐘的燃燒就能讓你的家溫暖 24 小時，而且

自己動手做的話，材料費只要 300 美元。

進階被動語態

It's been documented for decades, built thousands of times across North America, and

這項技術已經被記錄了好幾十年，在北美各地蓋了數千次，而且

it's illegal to install in most of the United States.

在美國大部分地區，安裝它是違法的。

Today, we're covering the physics of why it works, how to build one yourself, where this technology actually came from, and

今天我們要來探討它為什麼能運作的物理原理、如何自己動手做一個、這項技術的真正來源，以及

首先，來談談它為什麼能運作的物理原理。

Your fireplace has an efficiency rating of 10 to 15%.

你的壁爐效率大約是 10% 到 15%。

That means for every 10 units of heat stored in your firewood, Your room receives one to one and a half.

這代表你木柴裡儲存的 10 份熱能，你的房間只接收到 1 到 1.5 份。

The other 8.5 go straight up the chimney.

剩下的 8.5 份全從煙囪跑掉了。

As hot exhaust, you're not heating your home.

熱氣排放出去，你並沒有暖到你的家。

A modern EPA certified wood stove does better, reaching 60 to 80% efficiency.

一個現代 EPA 認證的木柴爐效率更好，可達 60% 到 80%。

But it stores almost no heat in the structure itself.

但它幾乎沒有將熱能儲存在結構本身裡。

When the fire dies, the warmth dies within inside an hour.

當火熄滅時，溫暖也會在一小時內消失。

A rocket mass heater runs at 80 to 90% efficiency.

火箭式蓄熱爐的效率是 80% 到 90%。

And it doesn't just burn the fuel more completely.

而且它不只是更完全地燃燒燃料。

It captures the exhaust heat inside a thermal mass before it can escape.

它會在熱氣逃逸前，將其儲存在熱質量裡。

Not generating more heat, capturing the heat you've already generated.

不是產生更多熱能，而是捕捉你已經產生的熱能。

The rocket mass heater uses a J tube feed system and an insulated combustion chamber.

火箭式蓄熱爐使用 J 型管進料系統和隔熱燃燒室。

You feed wood horizontally through the short side of the J.

你從 J 型管的短邊水準放入木材。

The fire burns at the bend, the vertical section of the J burns creates a powerful natural draft that pulls fresh air directly through the burning zone.

火會在彎曲處燃燒，J 型管的垂直段燃燒會產生強大的自然抽風，直接將新鮮空氣吸入燃燒區。

更多的空氣代表更完全的燃燒。

More complete combustion means higher internal temperatures, reaching 1500-2000 degrees Fahrenheit.

更完全的燃燒代表更高的內部溫度，可達華氏 1500 到 2000 度。

A conventional fireplace exhausts at around 600 degrees.

傳統壁爐的排氣溫度約為 600 度。

A rocket stove exhausts at 1500-2000 internally before that gas ever enters the thermal mass.

火箭爐在氣體進入熱質量之前，內部排氣溫度為 1500 到 2000 度。

By the time the exhaust exits the building, it's cooled to 100 to 200 degrees.

等到廢氣排出建築物時，溫度已降至 100 到 200 度。

Nearly all of that heat transferred into the surrounding mass on its way out.

幾乎所有的熱量在排出時都轉移到了周圍的質量中。

The thermal mass is where the real engineering happens.

熱質量是真正工程發生的地方。

The exhaust from the combustion chamber runs horizontally through a long channel buried inside a cob bench, typically 4 to 12ft long, depending on the room.

燃燒室的廢氣水準通過一個埋在土坯長凳裡面的長管道排出，通常長 4 到 12 英尺，視房間大小而定。

Cob is a traditional mixture of clay, sand and straw that conducts heat slowly and holds it for an extraordinarily long time.

土坯是黏土、沙子和稻草的傳統混合物，導熱緩慢且能長時間保持熱量。

As the hot gases travel through that channel, they transfer their energy into the surrounding cob.

當熱氣體通過該管道時，它們會將能量轉移到周圍的土坯中。

The bench surface reaches 90 to 100 degrees Fahrenheit.

長凳表面溫度可達華氏 90 到 100 度。

Warm enough to sit, warm enough to sleep on.

溫暖到可以坐，溫暖到可以睡。

Many builders run the thermal mass directly through their sleeping platform, heating their bed for free all night from a single morning fire.

許多建造者將熱質量直接穿過他們的睡臺，只需一次早晨的燃燒，整晚都能免費為床加熱。

You fire the heater for 30 to 45 minutes.

The COB stores that energy and releases it slowly over the next 12 to 24 hours.

土坯儲存這些能量，並在接下來的 12 到 24 小時內緩慢釋放。

One armload of sticks from your backyard 24 hours of heat without touching it again.

你後院的一把柴火就能提供 24 小時的熱能，之後就不用再管它了。

The emissions numbers are the detail that makes the legal situation genuinely absurd, and we'll get to that.

這些排放數據才是讓這個法律狀況變得荒謬的關鍵，我們等一下就會講到。

Rocket mass heaters produce particulate emissions 80 to 95% lower than conventional fireplaces and 50 to 70% lower than modern EPA certified wood stoves.

火箭質量加熱器的微粒排放量比傳統壁爐低 80% 到 95%，比現代 EPA 認證的燃木爐低 50% 到 70%。

The device the building code calls illegal produces a fraction of the pollution of the device it certifies as compliant.

建築法規稱之為違法的裝置，其產生的汙染比它認證為合規的裝置少得多。

Now, here's how you actually build one, what it costs, and

接下來，我們要教大家怎麼實際建造一個，成本多少，

why anyone with basic tools can do this in a weekend.

以及為什麼任何有基本工具的人都可以在週末完成。

The core components of a rocket mass heater are a J tube combustion unit, an insulated firebox, a horizontal exhaust channel, and

火箭質量加熱器的核心組件是一個 J 型管燃燒單元、一個隔熱的火箱、一個水準排氣通道，

None of these require manufactured parts, and none require professional installation.

這些組件都不需要特殊製造的零件，也不需要專業安裝。

The J tube is typically built from firebrick or refractory clay materials available at any masonry supply store for under $50.

J 型管通常用耐火磚或耐火黏土材料建造，在任何磚瓦供應店都可以買到，而且不到 50 美元。

The combustion chamber is insulated with perlite, the same lightweight volcanic mineral used in potting soil, which handles extreme heat without cracking or degrading.

燃燒室用珍珠岩隔熱，這是一種用於盆栽土的輕質火山礦物，它能承受極端高溫而不會龜裂或劣化。

The thermal mass channel is built from cob packed around a removable form.

蓄熱通道是用黏土填充在可拆卸模具周圍建造的。

You mix the cob on site from clay, subsoil, coarse sand, and

你們可以在現場將黏土、底土、粗砂和

straw in roughly equal proportions by volume.

稻草以大約相等的體積比例混合。

The mix is tested simply by rolling a ball in your hands.

混合物的測試方法很簡單，就是用手滾成一個球。

If it holds together without cracking and doesn't stick to your palms, the ratio is right.

如果它能保持形狀而不龜裂，也不會黏在手掌上，比例就對了。

You pack it around your flue form, let it cure for two to four weeks, then remove the form to leave the channel hollow.

你們將它填充在煙道模具周圍，讓它固化兩到四周，然後移除模具，留下一個中空的通道。

The benchtop is finished with additional cob smoothed and sealed.

檯面則用額外的黏土抹平並密封完成。

Total material cost for a basic system runs 200 to $500, depending on whether you source clay locally or purchase it.

一個基本系統的總材料成本約為 200 到 500 美元，取決於你是就地取材還是購買黏土。

Labor is your own time, typically one full weekend for the structure and another few days for finishing and curing.

工時就是你們自己的時間，結構通常需要一個完整的週末，後續的修飾和固化則需要幾天。

The burn process takes some learning, but not much.

燃燒過程需要一點學習，但不會太難。

You start the fire at the top of the feed tube with small kindling and gradually add larger pieces as the draft establishes a properly functioning rocket.

你們從進料管頂部開始，用小樹枝點燃，隨著氣流建立起一個正常運作的火箭，逐漸加入較大的木材。

Mass heater makes a distinct low roar as combustion intensifies, which is exactly where the name comes from.

質量加熱器在燃燒加劇時會發出低沉的轟鳴聲，這也是它名稱的由來。

The hotter the fire burns, the stronger the draft pulls the which brings in more air, which burns hotter.

火燒得越旺，氣流就拉得越強，帶進更多空氣，燃燒也就越旺。

The system finds its own equilibrium once you understand the rhythm of it.

一旦你掌握了它的節奏，系統就會自行找到平衡。

A morning firing takes less effort than making coffee.

The bench design is where builders get creative.

長凳的設計是建造者發揮創意的空間。

Some run the thermal mass as a long, curved bench along one wall.

有些人會把熱質量做成沿著一面牆的長彎曲長凳。

Some build it as a raised sleeping platform, which is essentially a modern version of a heating system that's been keeping people alive through brutal winters for 3,000 years.

有些人則把它做成抬高的睡臺，這基本上是個現代版的加熱系統，這個系統已經讓人類度過了長達 3000 年的嚴酷冬天。

Some integrated into a kitchen counter or work surface.

有些則整合進廚房檯面或工作檯面。

The cob is sculptable while wet and rock solid when cured, so the form follows whatever the space needs.

土塊在濕的時候可以塑形，乾燥後則堅固無比，所以它的造型可以配合空間的各種需求。

This is not a manufactured product you install.

It's a structure you build to fit your life.

這是一個為你生活量身打造的結構。

Because this technology didn't appear from nowhere, it's been proven across 3,000 years of human history.

因為這項技術並非憑空出現，它已經在人類三千年的歷史中被證實。

On three separate continents, Roman engineers built hypocausts under bathhouse floors 2,000 years ago.

在三大洲，羅馬工程師在兩千年前就建造了浴場地板下的輻射式地板採暖系統。

Hot combustion gases ran through channels beneath raised stone floors, heating the thermal mass above before exiting through vents in the walls.

熱燃氣通過抬高石地板下方的通道，加熱上方的熱質量，然後從牆壁的通風口排出。

The stone held heat long after the fire died.

石頭在火熄滅很久之後依然保有熱度。

Roman soldiers stationed in Britain used this system to survive winters the Mediterranean engineers had never experienced.

駐紮在英國的羅馬阿兵哥利用這套系統，度過了地中海工程師從未經歷過的寒冬。

It worked then, and the physics hasn't changed since.

當時它就很好用，物理原理至今也沒變。

Korean engineers refined the same principle into the Ondol over 3000 years of continuous development.

韓國工程師在超過三千年的持續發展中，將相同的原理精煉成 Ondol。

A furnace positioned outside the room channeled exhaust gases beneath a raised stone floor before venting outside.

一個設在房間外的火爐將廢氣導到抬高的石地板下方，然後再排出室外。

By morning, after the fire had been out for hours, the floor was still warm enough to sleep on.

到了早上，即使火已經熄滅好幾個小時，地板仍然溫暖到可以睡覺。

The system was so effective that Ondol floors are still installed in modern Korean apartment buildings today, Just with electric heating elements instead of wood combustion.

這套系統非常有效，Ondol 地板至今仍安裝在現代韓國的公寓大樓裡，只是改用電熱元件取代燃燒木材。

3000 years of field testing is about as validated as engineering gets.

三千年的實地測試，這已經是工程上最可靠的驗證了。

In Central Europe, the catalophen masonry heater survived the transition to modern heating and is still common in Germany, Austria, and

在中歐，catalophen 磚砌暖爐成功度過了過渡到現代供暖的時期，在德國、奧地利和

These are massive clay and tile stoves, sometimes weighing several tons, Built into the structure of the home.

這些是巨大的黏土和瓷磚暖爐，有時重達數噸，內建於房屋結構中。

They operate on identical principles to the rocket mass heater.

它們的運作原理與火箭式蓄熱爐完全相同。

Hot, fast combustion charged into thermal mass that releases heat slowly over 12 to 24 hours.

高溫、快速燃燒的熱能儲存在蓄熱體中，並在 12 到 24 小時內緩慢釋放熱量。

In Finland and Sweden, these systems never stopped being the primary heat source for rural homes.

在芬蘭和瑞典，這些系統從未停止過成為鄉村家庭的主要熱源。

When natural gas arrived with the promise of effortless heat, the masonry heater tradition died almost entirely on this continent.

當天然氣以輕鬆取暖的承諾來到時，磚砌暖爐的傳統在這個大陸上幾乎完全消失了。

A Provecho research center in Oregon brought it back in 1976, when Ianto Evans and Dr.

1976 年，奧勒岡州的 Provecho 研究中心將其帶回，當時 Ianto Evans 和 Dr.

Larry Winiarski combined the ancient thermal mass principle with modern combustion science to create the rocket stove design.

Larry Winiarski 將古老的蓄熱原理與現代燃燒科學結合，創造了火箭爐的設計。

Evans published the first edition of Rocket Mass Heaters in 1998.

Evans 在 1998 年出版了第一版的 Rocket Mass Heaters。

The book has never gone out of print and is now in its third edition.

這本書從未絕版，現已出到第三版。
