| 0:00.0 | Hello and welcome to another episode of the Fully Charged Plus Podcast. This week we're |
| 0:24.1 | talking about battery safety. Really, I think fairly critical, a topic as we transition to not burning |
| 0:36.1 | fossil fuels. Basically, if we're going to store energy in batteries, there are sort of intrinsic |
| 0:42.4 | dangers whenever you store energy in anything. You know, it's volatile stuff, so you have to be careful |
| 0:49.3 | and that's what is really bringing about this kind of getting in there early. You know, I make the |
| 0:54.1 | caveat during the recording, but I mean, it is, I think it's important to say, and I've actually |
| 0:58.0 | got the statistics. I'd just like to repeat them for you, because I think it's quite an interesting |
| 1:02.4 | thing, because the other day I got a tweet from someone who just said, oh, I'm not going to get an |
| 1:07.9 | electrical car, they're always bursting into flames. And you go, well, you know, there's dangers in |
| 1:12.8 | all technologies, no question. But here's the latest comparative figures. That is that there are |
| 1:19.9 | 55 fires for every billion miles driven. So, you know, not many. 55 fires for every billion miles |
| 1:29.0 | driven in combustion cars. So, you know, you drive a billion miles in your combustion car and it will |
| 1:36.3 | burn 55 times, billion, not million, billion with a B. So, you know, it happens, but it's very, |
| 1:43.7 | very rare. We know that. And electric cars, it's five fires per million miles driven. So, it's |
| 1:51.1 | got nothing to do with number of cars or all that. It's exactly the same metric. An electric car |
| 1:57.3 | has to drive a billion miles. And in that time, it might catch five times. There we go. So, that's |
| 2:03.4 | just to put that into context. That's from research done in the United States recently. |
| 2:10.1 | So, what we're talking about today is exactly that. So, there's a wonderful man called Joe Holdsworth |
| 2:16.9 | who I did meet many years ago on a completely different project and show and everything. |
| 2:26.4 | That would all be revealed in the episode. Before we start, before we go over to Joe who's found |
| 2:32.4 | a company called Metis Engineering. So, that we're talking about this company that have developed |
| 2:37.3 | amazing sensors. You'll hear all about it in the show. And it's really, and it's not just about |
