I think you mean CAT (the Centre for Alternative Technology) RG.

If you think visiting CAT is disillusioning, you should try working there. It put me off co-operatives for life!

Having said that, they do a lot of really positive stuff. It <I>is</I> worth visiting the centre, but it's best to go armed with the minimum of preconceptions.
