Oh wait, yes it does. Never mind then.
Electrolyzers depend on rare, difficult-to-work-with and sometimes toxic metals, but the method developed by Chris Berlinguette and Simon Trudel uses metals as common as rust. It delivers results comparable to current techniques but costs about 1,000 times less.
This seems like it could make the use of fuel cells common place with an economical fuel source. If this pans out, what other hurdles might need addressing to get a fuel cell into every home?
Here's what I know:
0. Falcon 1: Failure. (Never flew; launch aborted & it imploded later on when a tank was drained)
1. Falcon 1: Failure. (First stage engine failure)
2. Falcon 1: Failure. (Second stage oscillation & engine failure)
3. Falcon 1: Failure. (Stage seperation issues)
4. Falcon 1: Success. (Deployed RatSat)
5. Falcon 1: Success. (Deployed RazakSat)
6. Falcon 9: Success. (Deployed dummy payload)
7. Falcon 9: Success. (COTS 1; Deployed & recovered Dragon)
8. Falcon 9: Success. (COTS 2; Dragon to ISS and back)
9. Falcon 9: Partial Failure. (CRS-1; Failed to deploy secondary payload)
10. Falcon 9: Too early to say. (CRS-2; Falcon 9 performed flawlessly, but Dragon is having issues.)
So yes, SpaceX has had some problems, but the failure rate only approaches 7/12 if you count every little mishap as a "catastrophic failure". The only total failures were with the Falcon 1, when the company was still figuring things out. Yes, CRS-1 had an engine failure and couldn't deploy its secondary payload, but the Dragon itself still got to the ISS in good shape. And as for the current flight, it could still go several ways:
Success (if the Dragon arrives Sunday and it's declared successful despite the hiccups and schedule delay)
Partial Failure (if the Dragon arrives late and it's consequently not considered a full success)
Failure (if the Dragon dies and doesn't survive re-entry or, heaven forbid, collides with the ISS)
Abort (if the Dragon re-enters and splashes down intact)
Okay I've gone on yakking way too long, I know.
tl;dr – SpaceX has had some issues in the past, most of which got ironed out with the Falcon 1. F9/Dragon has had some hiccups, but so far every primary mission has been successful—and the current one hasn't failed yet.
Gee, Toto, I don't think we're in Kansas anymore.
