Who needs to climb in? > What are you using to generate steam for that? How many watts of > electricity does it use? Two steam room generators. I will check the wattage. They are rated 240V running at 208V. Works fine on the lower voltage just takes longer to get it in flow. As yet we have no data on power consumption and/or power cost. > We are using the baby (4' x 5') foam board steam box I made one of those from plans from your buddy. It has practical applications. Used it on a set of windows for the B from Westchester. The big box is a whole different reality.

Interesting idea but will have to think hard on figuring out how to get the monster to do vertical.

We are not as yet sophisticated on feedback, mostly focused on brute DO IT technologies.

I am not aware of any testing on that -- if not you then who? -- thought about it, but very highly doubt it occurs at all. Do we need an MIT person on that. Environment obviously conditions the process. I had dreams of doing on-site work on a cornice in Garden City w/ a production line of steam boxes custom built... but the owner freaked for whatever reason. Maybe I should give her your name. I liked her but I don't think she was quite clued in to how far her house had been neglected. I will talk w/ you at the IPTW on this technology. I would like to collaborate. ][<en -- Orgrease-Crankbait <http://orgrease-crankbait.blogspot.com/> Video, audio, writings, words, spoken word, dialogs, graphic collage and the art of fiction in language and literature. -- To terminate puerile preservation prattling among pals and the uncoffee-ed, or to change your settings, go to: <http://listserv.icors.org/archives/bullamanka-pinheads.html>
