Not entirely sure you can pump 20kW into a room for any significant period of time before something melts.

Sylvia.

Depends of the room size.

I have a 7.5 kW (three phases at 230 V) heater in a 1.5 x 1.7 m room and it takes nearly a half an hour to reach 100 C.

Opening the door from sauna to the washing room (2 x 3 m) and the heater struggles to keep the temperature at 80 C.

Of course there are timers that needs to be manually reseted in case one pass out, normal thermostats to set the desired temperature and an overtemperature switch, which disconnects the whole system at 130 C if the thermostat fails.

As far as I know, Winfield Hill is the only other Harvard graduate that reads SED. He could look at the Harvard website and see if I am a graduate or not. So if I am not a Harvard grad , I am at risk of being exposed.

Winfield Hill has been posting here a lot longer than you have, and I didn't know that he was a Harvard graduate. Having co-authored AOE, he presumably doesn't feel the need to find anything else to boast about.

Not near as warm in Delaware, but a lot closer to being like a sauna. Lots of humidity.

Dan

The previous Hot day here was only 92 @ 39% RH. Really nice day. now I'm still waiting for 96 today, Its 12PM and only 80. Don't think it's gonna happen.

Cheers

I am not sure when I first posted on SED. But was reading and posting to some use groups before there were browsers.

I looked up Winfield on the Harvard website. He graduated from GSA in 1967. He has never logged into the Harvard wed site.

Dan

Apparently you do not have a copy of AOE. It says he is at the Rowland Institute at Harvard.

Dan

I'm not a great fan of saunas, but then they are designed to make you sweat!

o some use groups before there were browsers.

You can look it up on the Google Groups web-site - or you could when I last tried, though Google seems to be making it progressively more difficult.

My first post there is in 1996, and Win was a fixture back then.

  1. He has never logged into the Harvard wed site.

Why would he? My university does pester me for contributions, and the unive rsity college where I lived as an undergraduate (think frat house, but set uo by the Methodist Church) does the same. I never give them any money, but have attended two get-togethers organised by them - one of each - mainly b ecause old friends were involved.

Institute at Harvard.

The Rowlands Institute was set up and presumably paid for by Edwin Land (of Polaroid fame) back in 1980. It's at Harvard but the relationship with Har vard University has never been spelled out, and I doubt if Winfield Hill is listed as a member of the Harvard academic stuff. I do have copies of AOE

- 2nd and 3rd editions - and was well aware that Winfield Hill works at the Rowland Institute (and that his co-author - Paul Horowitz is a professor a t Harvard).

What I said was that I was unaware that Winfield Hill had been an undergrad uate at Harvard, which is a very different affiliation.

Bill Sloman, Sydney

Before you said you were unaware that he was a Harvard graduate. And he is that, but now you say undergraduate. And he was not a undergrad at Harvard. He was a GSA graduate.

Dan

is that, but now you say undergraduate. And he was not a undergrad at Harv ard. He was a GSA graduate.

So he went to graduate school at Hardvard - and dropped out of it. It's sti ll very different from being a member of staff there. The Rowlands Insitute seems to have become part of Harvard in 2002.

"Update: On July 1st, 2002, the Rowland Institute became part of Harvard Un iversity and its name was changed to the Rowland Institute at Harvard. We o perate as an independent "center" in FAS (the Faculty of Arts and Sciences) and remain located in our laboratory on the banks of the Charles River nea r MIT."

to quote Winfield Hill's web-site.

From the authors detail in AOE " After dropping out of the Chemical Physics graduate program at Harvard University, and obtaining an EE degree, he beg an his engineering career at Harvard?s Electronics Design Center."

Since he dropped out of graduate school at Harvard, he might not have got a degree from there - and certainly wouldn't have got a graduate degree. Whe re he got the EE degree isn't spelled out - Harvard would have been the lik eliest place, and you should be able to get better evidence than I can via the Harvard alumni association - but so far your original claim is not prov en, and you seem to be having your usual problems with comprehending the th e implications of what you have posted.

You are very confused. Where do you get that he dropped out of graduate sc hool?

Dan

He's a leftie. I can't help thinking it a bit inappropriate to keep posting someone else's personal details.
