Keeping your beer cool

[stimpee]

Recently Grolsch here have launched a campaign where they are giving away free beer coolers. Remote controlled at that! But how do you keep your beer cool in the park/away from home?

The grolsch thing if you want to buy it: http://www.grolsch.nl/Default.aspx?pid=146&product=2934&cidx=7&skip-agecheck=1

and a couple of other cool looking ideas i found:
Tinchilla! http://www.cybercandy.co.uk/search/index1.php/url_indprod/xdbc_945/Tinchilla%20-%20Instant%20Can%20Cooler.html
IC Can: http://www.tempratech.com/chill1.html

Remote control beer cooler (similar to the grolsch thing): http://www.ozgadgets.com.au/remote-control-drinks-beer-cooler.html
same cooler more pics: http://www.thedrunkengoat.com.au/?stg=502&view=502

Hand powered version of the Tinchilla? http://rinkya.blogspot.com/2009/12/ice-cold-beer-in-90-seconds.html

I like this idea of cool beer in 90 seconds. cant see how it wouldnt squirt all over the place tho when you open the can. Plus I think a cooler for bottles would be handier here...

Anyone got tips/gadgets?

yes. in the entire world

Hmmm $350 is a bit much.

and "warm" beer i can save for drinking real ales in a bar (which are just kept at cellar temp, not really "warm"). drinking unchilled lager/pilsener out of a can is just wrong :p

no-one seriously thought about this? carrying a cooler box around is impractical.
