Helmet-cams appear to be getting cheaper and more readily available.
http://www.weatherconnection.com/product.asp?itmky=882426&s=froogle http://www.distributorcentral.com/images/products/b8a42537-8e69-4ff2-b557- I am predicting that in less than 10 years, you are going to see at least one caver on your trip wearing a helmet-cam. And in the future, video quality will improve, memory will improve, etc. For example, in stores now is Sony's new memory chip, the M2, ( for their new cell phones ) that is 512 megs and is tiny. http://www.mymemory.co.uk/images/products/1142697997-large.jpg [ the web-site claims they go up to 4 gig ? ] In addition, they will probably discover ways to compress the video better, so that future cavers can make longer mpegs or something similar. ( I believe they have already found a way to make .jpegs smaller and better resolution ). Popular Science is reporting new battery research. Imagine if you could have a helmet that was 2 layers of carbon-fiber and sandwiched between was a layer of some sort of flexible battery material ( see ORB ), sealed between the layers and fully water-proof. http://future.iftf.org/2005/12/yet_more_flexib.html Is this your next caving helmet ? http://www.jeccomposites.com/composites-news/2275/DXL-helmet-wins.html It is not hard to find a carbon-fiber motorcycle helmet.
