Perhaps - but if they are roughly equivalent in safety with regards to inherent explosiveness but gasoline is better in safety with regards to random people using it, then gasoline has hydrogen beat overall on those two aspects of the safety issue, doesn't it?

Maybe. I'd have to look more into the issue to answer that fully. I do not think hydrogen is inherently much worse in regards to random people using it for such things as automobile fuel (with the right kind of car and all ).

Warning system necessary -> increased complexity -> harder for the average person to deal with safely -> more dangerous

How so? Gasoline tanks have such warning systems, showing how much gas is left in the tank. People can deal with that just fine.

Where did you get the impression that I belive they do often explode

I didn't. It was just a general statement.

A fuel gauge on your car isn't a safety issue, except perhaps for cases where an empty tank will strand a person away from life's necessities. You were proposing a gauge as a method of detecting leaks, which is a totally different purpose. Such a thing as a safety device to detect leaks would either require that the operator note the fuel level after one use and before the next to check for a drop when the fuel wasn't being used or an alarm that watches for drops in fuel level when the tank isn't being properly drained. Further, it would be extremely difficult to produce such a thing that could detect leaks during operation, as it would need to be able to distinguish the rate of loss of fuel due to proper use from the rate of loss of fuel due to a leak. A gasoline fuel gauge just checks the current level so the operator has a good idea on when it is time to stop for fuel; it is seldom used for leak detection, as it is simpler just to put a piece of dry cardboard under the vehicle and check for wet spots after a time, or even just look for oil slicks on the pavement / driveway / puddles. Most people don't use fuel gauges as a method of detecting leaks; it is simpler to use other methods for liquid fuels - you can see the results of most leaks quite easily, as they leave discolored spots on things below. Gaseous fuels, on the other hand, don't do that. The only ways to detect a leak in gaseous fuels are: watch the pressure when it isn't being used (more complex than looking for discoloration under your car) (theoretically, the tank doesn't need to be not in use - it is simply a matter of knowing the rate of use and comparing that to the rate of loss - the difference is the leak; however, that is easiest when the rate of use is zero), remove all components with possible leaks and subject them to liquid tests under pressure (as is done for tires so a leak can be repaired - complex, difficult, and time consuming for embedded components), add something to the gas so that a leak can be smelled (but that doesn't tell you where the leak is, only that there is one), or listening for hissing (no hissing doesn't mean that there are no leaks, however; likewise, this requires a quiet environment and can't tell one exactly where the leak is coming from). With liquids, a leak produces a trail that can usually be followed back to the source with fairly minimal effort, and a spot on the ground to give a clear indication that a leak has occured, and will often produce a dripping sound (equivalent to a gaseous fuel's hiss on leaking in most respects). Leaking gasoline naturally produces a scent, no additives necessary. Further, almost any method for leak detection that works with compressed gas fuels will also function for liquid fuels.

ARRRRRRRRRRRRRRRRRRRGGGGGGGGGGGGHHHHHHHHHHHH

lines are down again.

I am at work.

And the starter went on my car.

And I am almost finished triming the hedges.... 12 more meters to go. And they went from 560 cm in height to 200 cm in height ( i cut about 35 meters of the stuff with my new hedge trimmers. Manual back breaking one with the added sore arms and hands option pack. )

Next week i get to rent a chipper and have some fun.

i just found out that this will be ongoing problem for the next 2 weeks.

So to all my PBW games and games I am playing in.

Sorry if I miss turns or I am late replying to Messages.

AS PBW IS SLOWLY BACK UP. GAMES WILL REMAIN ON manual run until 100% everyone can do the turn.
