 I got involved with the Cambridge Museum of Technology back when I was 16, I used to be a row on the river, used to row past the museum and wondered what was going on at the place, intrigued what was going on, and with it being in steam over the last couple of days, come along to help and support and run the boiler for them. The most satisfying part of working on this project is actually physically seeing it back in steam again after all these years. You can feel the heat coming off the boiler, you can smell the hot oil and the grease and that in the engine room, and you can actually feel the heat in the engine room, which is something that hasn't been in there for years. The engine just rocks backwards and forwards, it doesn't do anything other than rotate one way and then the other way, it's not like conventional steam engine that rotates, and it's part of Cambridge's history really. This is the sewage pumping station that used to pump the sewage away from Cambridge, so for it to be back in steam again and showing the public of how it used to pump the sewage away is something that really needs to be seen by the public. To apologise, the safety valve is just lifted.
