Hydrogen as fuel is just an energy transport material anyway.
Getting the hydrogen, which exists around us everywhere in abundance, is the hard part. Making pure H2 requires energy, even though it's right here, no digging required. Electrolysis is a common way to produce it, but then the question becomes, where did the electricity come from to break down the water? And then the same question about the provenance of the energy transport "material" of electricity? (I know it's not a material...). Wind, solar, hydro? Those sources don't (materially, material, ha!) to an increase of CO2 emissions. But what if it's a coal fired power plant that generates the electricity that decomposes the water that produces the hydrogen that is burned to move the truck? Not as carbon-neutral now, is it?

Right, I don't think hydrogen is a viable fuel because of the high expense of producing it (money and environmental footprint)... unless oil becomes scarce.

If you could just set up a solar panel and make hydrogen all day, wouldn't that be interesting because that would be stored energy?
But it seems to me, if this worked, it would already be happening, cos smarter people than us have considered the problem in detail. Here we are talking about this shit and pretending we know what we're talking about. |

And again from thermodynamics, for every ten units of energy to make and store hydrogen, only one unit of energy does productive work.
What creates that hydrogen? Burning oil, coal, etc. Why is it clean? Hydrogen as a fuel is only a temporary energy storage medium. It is not an energy source. And it must be used quickly because even all pipes and tanks constantly leak hydrogen. For transportation, nothing has the energy per weight ratio that petroleum provides. That is why research into lithium (stifled since the 1960s) is now occurring in places other than Japan. Last edited by tw; 12-10-2016 at 11:58 AM. |

Lithium is a hell of a drug, man.

But the central committee of the communist party could not enrich themselves on something so useful - for brains and batteries. So they pushed opioids. Opioids are bad for brains and batteries. But opioids enrich and power the 'right' people.

Yesterday at dusk, I passed someone hauling a backhoe, going south on 476.
Some dude was going 65 hauling a backhoe, and switching lanes fast as if they were driving a car. I passed them and did 70 for a while. It's probably twenty years ago, but I remember a story where someone was hauling construction equipment up the Schuylkill Expressway incorrectly, and a piece broke off and killed a woman instantly. Five miles later, 476 intersects into 95. As usual, there's congestion and a slowdown, just as the ramps and merges are getting started. Two lanes are slowing down quick. Don't cha know, I hear big metal braking sounds and rumble rumble and here comes Mr. Backhoe fast down the skinny right shoulder. He didn't notice the congestion and couldn't slow down, and this was his emergency maneuver. No doubt, the fuckin' guy was doing 65 right into the I-95 south merge. It can slow down fast, but this was still a light curve at that point. (For locals, it was just before the MacDade ramp merges in. They guy wound up in the lane that ramp creates, so suddenly he was fine and could merge just like he came up the ramp.) I imagine Pamela has low respect for these part-timers, who probably get a CDL so they can make an extra hour's wages per day to drive the gear to the site. It's the end of the day, Saturday, you know he was rushing to get home. |

Here in KY, I believe you can drive a single axle (maybe dual axle, too) with no CDL if you own the vehicle. I think. I'm wrong a lot. More and more.

UT, what was the tractor vehicle? A pickup or a commercial truck? I have little respect for the guys who haul RVs and small car haulers and such because although they have CDLs and follow the same rules I do, they seem to think they are special and should be catered to everywhere.
Grav, you need a CDL to drive intrastate as well as interstate in any CMV; some rules are suspended if it's a registered farm vehicle but not the license. |

CDL is for over 25,000 lbs isn't it?

It was like one of these deals (obviously not this particular company, but this style truck and bed)

Here in the UK in 1997, the unsecured back hoe of a digger being transported as pictured above, swung out and hit a car killing five people in the process.
I remember the accident quite well, but surprised that it was nineteen years ago. Quote:

Why had it never swung out before? What made the turn so centrifugal this time? In decades of people driving unsecured diggers around, no one had ever made a fast turn?
