The Whirlygig was once again featured at the fabulous Santa Rosa Handcar Regatta

Oct 2010 - May 2011
The Whirlygig was featured at the 1st annual Steampunk Form and Function exhibit, Charles River Museum Of Industry and Innovation in Waltham, MA. Thanks to Bruce Rosenbaum of Modvic for being a persistent and friendly pest.

Oct 2010
Thanks to the support of dozens of friends and some total strangers I raised $3000 in my Get The Whirlygig to the Mueseum Kickstarter.com fundraiser campaign, allowing me to transport the bike all the way across the continental U.S. and fly out to the opening of the exhibit!

May 2010
The Whirlygig was seen whirlying around the San Mateo Maker Fair.

Sept 2009
The Whirlygig was featured at the 1st annual Handcar Regatta in Santa Rosa, Ca. I traveled there as part of the Ratchet and Rumble Crew - we built the Lumbering Contraption a giant human powered hamster-wheel hot-rod that runs on the railroad tracks!

May 2009
The Whirlygig dazzled kids of all ages at the San Mateo Maker Faire

May 2008
The Whirlygig traveled to San Mateo, California in May 2008 for the Bay Area Maker's Faire and recieved a Make Magazine Editor's Choice Blue Ribbon!.

THANKS TO:

Phil "Peef" Sadow for electrical assistance, Orion Fredericks for hermetic TIG welding, Sean Orlando for reality checking me and giving me the fire-extinguisher tank, and Andrew Jones for letting me stay an extra month in my old shop at XIAN Productions to get it all done!
And last but not least, thanks to Michael Christian for teaching me so much about welding and metalwork and whimsy.

Please also take a look at the STEAMPUNK TREEHOUSE! - a project I helped build for Burning Man 2008, and a major inspiration for my Whirlygig.


The Whirlygig Emoto Story

A Steam Electric Hybrid Motorcycle

Built by Tom Sepe in August 2007.

The Whirlygig boiled out of a head-on collision from three conceptual directions:

1) I've always wanted to build an electric vehicle, and a minibike is a very practical learning platform; its less expensive for all the components, it doesn't eat up your whole workspace, and its easy to reach into, get underneath or turn upside down without heavy equipment. Plus its just cute. Chicks dig it. Guys too.

2) Years of building large-scale Art Cars for the Burning Man festival taught me that I didn't want to be trapped in a box; no windshield, no doors, just full access for people to be able to engage and interact, yet still capable of toting a couple of passengers across the desert for adventures and necessities. Parking, transporting and storage and greatly simplified as well.

3) Falling in love with Steampunk. The monochrome Mad Max is soo 1990's, the Pirate theme is worn out (but we still love stripes!), and although the Nouveau Circus movement is whimsical, it doesn't have the practical gear-headedness of the Steampunk aesthetic. So you get the romantic warmth of copper, brass and old wood, but the practicality of contemporary technical application... and heavy dose of whimsy & fictionality.

In December 2006 I started by disaster testing - strapping whatever components I could find at my workshop with the help of Phil 'Peef' Sadow and then crashing into things. Here's a video timelapse where we built the prototype bike in one day at XIAN Productions:

The frame was donated to me by Lyell Cash, a fantastic catering chef I work with, which was buried in his garage for 40 years. Here's what the original must have looked like: I then transported it down to Lightning in a Bottle, a music and performance festival in Santa Barbara, and soon realized that it was underpowered and too small. It sat on the back burner for a year, until August 2007 when I spent a intense three weeks fixated on the realization of the vision.

I began with inspirational research on the interweb - brassgoggles.com, steampunkworkshop.com, and numerous steam engine enthusiast's sites. [farm3.static.flickr.com] I'm lucky because there is a group of artists in Oakland called KSW - - that strives to collaborate and provide steam-power to kinetic sculpture. Sean Orlando and the Steampunk Treehouse crew upped the ante of aesthetics for me. I helped design and weld some of the branches for the treehouse while working on the bike, and the level of craftsmanship and creativity inspired me to take my art to the next level. And the more I worked on it, the better it got, and soon I realized that it deserved more and more of my energy to complete. For the week before Burning Man 2007 I was alternating working all-nighters and getting 4 hours sleep every other day.

Under the "hood": The "pancake style" electric motor is a 15hp Etek, what conventional technologists would describe as a wave wound axial air gap brushed DC motor, and uses one-tenth the steel and one-half the copper as a conventional DC motor and is only half the size. This motor has been a standard in electric motorcycle racing and in certain configurations can reach speeds in excess of 60mph! Two 12Volt deep-cycle marine batteries wired in series provide the 24Volt power, which is managed by an ALLTRAX AXE 500amp controller, some 24V solenoids and a gaggle of knobs and switches that have to be triggered in the right sequence to prevent unwanted borrowing. The Tote Goat was a street-legal motorbike, and once I mount the license plate and deal with brake lights I should have no problem satisfying the DMV. As long as they don't actually look at it. For now I ride it in a shroud of steam and jedi-mind tricks, and plan to show it off at the upcoming Maker's Fair in California.


REGARDING THE STEAM:

In the desert I discovered that having a warm blast of moisture was a real pleasure for the ladies.The steam boiler evolved as form before function, as I originally planned the bike to just look like a steam-machine, and size and placement dictated a small boiler. However I acquired a small pneumatic grease pump, which could theoretically oscillate on steam, but aesthetics, time, and minimal steam power complicated its integration. I decided to build the steam-boiler nevertheless, starting with a fire extinguisher tank that I cut a hole in the bottom, welded a through tube into it and with the help of Orion Fredericks [www.orionfredericks.net] we were able to TIG weld a hermetically sealed chamber with ports for drainage, output and a 100psi safety valve

The heat to produce the steam comes from a hardware store bought propane torch, which has the added benefit of providing a jet of blue flame out the back of the bike. An unexpected boon was the resonant frequencies produced by the movement of hot air through the tube - giving the otherwise silent electric bike a mighty jet-powered sound. I also plumbed in a tiny "dead man's" steam whistle controlled by a small solenoid valve right off the boiler.
