Depending on how easy it is to transport the equipment for making it, how easy it is to create a viable shape, lifting power per volume, etc. this idea might have many more uses than just advertising stunts. <BR/><BR/>I also have to wonder how a client would feel if they shelled out for, say, a giant Swoosh logo over London, but then found that it had blown out down the Thames estuary before anyone saw it...<BR/><BR/>And I agree with Mr Smith on the improbability of helium being a greenhouse gas. I certainly can't find anything to support the claim, anyway.256noreply@blogger.comtag:blogger.com,1999:blog-11787852.post-28292540362538411342008-04-20T05:58:00.000-07:002008-04-20T05:58:00.000-07:00I'd be interested to know where Alex is getting his information. Helium is a noble gas and as such, rarely reacts with anything. It also does not accumulate in the atmosphere (despite large scale manufacture) like carbon dioxide. The only danger of helium is an extended period of breathing pure helium can quickly result in death due to oxygen starvation.<BR/><BR/>As for a the clouds, it's a great example of lateral thinking and hopefully will make its creator quite wealthy.Justin Smithnoreply@blogger.comtag:blogger.com,1999:blog-11787852.post-14584633350405162702008-04-19T22:31:00.000-07:002008-04-19T22:31:00.000-07:00You can send them our way, we'll update with your credit.

Just no. Don't. Bury it in some cellar archive and never think about this again, dear companies. Plus, helium? Helium is way more serious as a contributor to the greenhouse effect than carbon dioxide. So: double don't!Alexnoreply@blogger.com
