JM relayed points from his discussion with Bob Laishley at Beaulieu

• Caterham could do what I’m proposing to do tomorrow (JM agreed)
• But Caterham needs to have a car that has at least some credibility on a track, no good as just a Sunday car as the first thing journalists would want to do is take it to a track. Then they’d report that it overheated and ran out of juice in 15 minutes.
• Therefore, CC are watching but waiting for battery technology to get to the point where there’s a viable Caterham offering

Decided to go with following communications:

• Monthly meetings
• JM to put notes/minutes up on a CL7C Blog
• JM is blogging at Purplemeanie.co.uk
• JM will post to BC when there’s a new blog post on Purplemeanie.co.uk

JM went through some of the draft of his design presentation for remaining 35 minutes.
