this should help the cash flow, page-27

It will be interesting to see if the increased revenue has had a significant impact on the cash burn rate for the quarter and how much longer available cash is projected to last.
Also, I remember reading the comapany was developing units to 'suit the specific needs of particular customers in the UK' I assume this would have an ongoing impact on R&D expenditure (along with regular R&D) but would have the benefit of opening up more markets.
