Pic of Bigelows first station design

[docm]

Found this rendering of Bigelow's station design on MSNBC.<br /><br />1 Sundancer + 2 BA-330's + hub + propulsion bus <div class="Discussion_UserSignature"> </div>

I'd like to see the power budget. Big cooling fins, small solar panels. Maybe the panel technology NASA uses (the flimsy orange stuff) is not as efficient as the stiff-panel flip-out kind like we see here, and used by the Russians.

The Sundancer module will be 2 decks also. I thought the original design had it longer with a single deck? <div class="Discussion_UserSignature"> <font color="#993300"><span class="body"><font size="2" color="#3366ff"><div align="center">. </div><div align="center">Never roll in the mud with a pig.

Looks like keeping the same diameter & just making it shorter makes production tooling easier. <div class="Discussion_UserSignature"> </div>

What kind of light bulbs does the ISS use?<br />Bigelow uses LED's ( I asked)<br /><br />"We are currently utilizing LED light panels and bulbs manufactured by Ledtronics Inc. in our modules."<br /><br />Thire may be other power saving devices on board.<br /> <br />

The Bigelow site has not much at all about either Sundancer or BA-330. Just the Genesis projects. Where is this info coming from?<br /><br />I know in the past NASA has used flourescent lights. The ISS sure looks brightly lit inside on TV, but that could be the camera. I don't think just changing the light bulbs would be a big enough savings.<br /><br />Where is that ISS orientation manual (300 page pdf) online? I lost my copy in a disk crash last week. <img src="/images/icons/frown.gif" /><br />

Google found the NASA pdfs for me. They are rather old. They say at station completion the expected average payload power consumption will be 30 kW. Could not find anything about where it all goes. Sub-zero refrigerators? Heating/cooling/O2-generation? Lots and lots of electric motors for sure.

Well I emailed Bigelow aerospace and asked if they used <br />this:<br />http://www.world-science.net/othernews/050310_suntubefrm.htm<br /><br />the reply was:<br />... Thanks for the inquiry.<br /> <br />We are currently utilizing LED light panels and bulbs manufactured by Ledtronics Inc. in our modules.<br /> <br />Now what is the power difference between Fluorescent light bulbs, and LED's?<br />

Baseline: 60w incandescent @ 800 lumens<br /><br />Fluorescent: 15w - 20w<br /><br />LED: 3.5w<br /><br />Recently an LED was announced by a Siemens subsidiary that is />1,000 lumens, about equal to a 75w incandescent. A 100w incandescent is 1700 lumens. <br /><br />LED "bulbs" are heading to your home sooner than you'd think and their limited soectrum issue is being resolved. Long life, very low power but it'll take time for prices to come down. <div class="Discussion_UserSignature"> </div>
