Dear Makers out there

Here is the proof, that Steampunkers are not only happy with copper and brass! We have a "Green Thumb" too - but some brass, glass, wood and steel has to be in for sure!

The "Biosphere Model 1876" is a unique wonder of nature and hosts a living small beech tree. This small oeko system needs 10ml of water per month and is a real eyecatcher in the living room.

Step 1: The Giant Bulb

By chance I found on a flea market a realy giant light bulb. It was broken, but the size was breath taking and I had to get it for a few bucks.

At home I cutted the metal socket carefully with a metal saw. Then I packed the glass bulb into a towel and carefully broke out the filament and took it out of the bulb from below. Work carefully and slow, it would be sad to brake the bulb. Wear gloves to protect your fingers from the glass!!

As a base I used a black steel ring and an old gear from the yunk yard. The hole in the gear fitted by chance exactly to the socket of the cutted light bulb.

<p>how does the plant recieve water?</p>
<p>Hi</p><p>See here:</p><p>As you can see my &quot;Biosphere Model 1876&quot; is not completely sealed. At the socket of the bulb some air can circulate and if you lift the bulb a little bit you can add the 10ml of water with a pipette.</p><p>Sincerely yours Dan</p>
<p>Love it, great job!</p>
<p>Thank you very much Josh!</p>
<p>see how a friend of mine does it</p><p>http://morganruben.com/</p>
Wow!! Amazing! A great inspiration! Thanks for the link!
<p>Gratulation zum 2. Preis!</p>
<p>Lieben Dank!!</p>
<p>Love the device. And this question may sound stupid but... is the plant alive after 4 days without fresh air renovation? Don't seems a long future for this plant. </p>
<p>Thanks for your feedback. The bulb is not sealed at the bottom. There is a lot of space in the socket for air circulation, especially during night and day. The tree is now since a longer time in the Biosphere and looks pretty good - it didn't grow much, but that's ok.</p>
<p>I have to say, this has got to be one of my absolute favorite steampunk contraptions I ever seen on here! Beautiful work.</p>
<p>Thank you very much for your nice comment!</p>
<p>Awesome project. Did you add any LED light inside that vacuum tube? That would add some nice ambiance when it's getting dark in the room. Beech tree (had to google that translation as I am no native English) is quite slow growing I believe. However, that bulb has enough space for many years. But what I am wondering, is there any grow of damp (German: beschlagen) inside of the bulb?</p>
<p>Thanks for your feedback. You know, I'm an old Steampunker and I prefer real light bulbs ;-), so I do not much with LED's. But you are right, it would look nice!</p><p>Yes, Beech trees grow very very slow. That's why I choosed one.</p><p>Yes, during the night the glass is covered with condensed water, because the glass cools down. During the day the drops disappear and some water is rinning back thrue the socket of the bulb into the plant pot.</p>
<p>Sure, got it :-) But a small bulb as we used for our model trains a couple of decades ago would do the trick as well.</p>
<p>Lovely. Courageous. Fun.</p><p>I love it. </p><p>Thank you.</p>
<p>Thank you very much Ricardo!!</p>
I believe that these lamps were used in lighthouses and are extremely rare. However it is possible to get hold of very large round bottomed flasks from laboratory suppliers so someone might have one.
<p>I searched the internet for this bulbs and found out, that they were used for huge industry halls and for theater lights....</p>
<p>Wow! This is so awesome! I don't think I have seen a light bulb that big before.</p>
<p>Thanks for your comment. I was thinking before that there is nothing bigger than that: <a href="https://www.instructables.com/id/The-Giant-Edison-A-Big-Size-Steampunk-Lamp/" rel="nofollow">https://www.instructables.com/id/The-Giant-Edison-A...</a></p><p>But then I found this huge one!!! :-)</p>
<p>Really neat idea. I've admired the lightbulb terrariums before, and adding the steam punk theme is a great touch. Voted! Thanks for sharing!</p>
<p>Thank you very much Teisha!!</p>
<p>That is stunning the bulb is huge, I had one and made a much smaller version awhile back.. it is still alive and doing well... I never thought about doing it right side up..</p>
<p>A wonderful idea!! If I can get one more of this huge bulbs I will create one more with the socket at the top... Thanks for the inspiration!</p>
<p>that looks awsome, just that globe is not so easy to find, but will keep looking</p>
<p>Thank you very much! It's a bulb from a large industry production site... they still use this old bulbs, I found out....</p>
<p>Lovely wish i could find a similar bulb</p>
<p>Thanks, turbonegro. I had really luck with this bulb. Hope to get more of them. May you could use a ballon bottle too....</p>
<p>awesome, what are you going to do when the tree gets much bigger?</p>
<p>...I will plant it back to our garden. We life in a nice forest, so there are many nice trees to fit later...</p>
<p>Perfectly! </p>
<p>Thanks grols! Greetings from Switzerland!!</p>
Love it
<p>Many Thanks, my Lady. I will try your <a href="https://www.instructables.com/id/Honey-And-Cinnamon-Facial/" rel="nofollow"><strong>Honey And Cinnamon Facial</strong></a> instructable ;-)</p>
I cast my vote.
<p>Thank you tcolo'n! That's very nice!</p>
<p>I just happen to read an article about an <a href="http://earthweareone.com/this-garden-in-a-bottle-has-been-thriving-since-1960-sealed-in-its-own-ecosystem-and-watered-just-once-in-53-years/" rel="nofollow">enclosed ecosystem</a> like yours but made in 1960.</p>
<p>Thank you for the link. I studied this kind of bottle gardens before I started my project. It seems that you need some size that it works - my bulb seems to be too small..... but I have still plans for a bigger Steampunk Sphere......</p>
Simply beautiful!
<p>Many thanks for your nice feedback. The tree is still alive and I hope it keeps long!!</p>
This is gorgeous!
<p>Thank you very much!! Nice to see that people like this &quot;Bulb Garden&quot;...</p>
