No cowcow your wrong. The Hindenburg is not kept at high pressure. It would not float if was. I find the irrational fear that still exist so long after the accident a bit ridiculous. People don’t even think twice about having large quantities of highly combustible gasoline in the car but slap the label of hydrogen and everyone becomes a little nonsensical.

its great. simply great. i would be glad to know about the storage system
the rate leaking rather howmuch leak proof it is
the use of hydrogen is vast in future not only as car fuel
it can do much greater job in different form in near future

Coulld the dead algae still be processed for the oil?

GreyFlcn… hydrogen from algae is inefficient in these early stages of research, but think about how long the electrolysis fuel cells have been around and the energy balance of that process is not even close to economical feasibility. Furthermore, claiming biodeisel production from algae is stupid should require a little more backing research. Algae’s oil per weight is extremely higher than those of other biodiesel feed stocks (ie soy, rapeseed); some have recorded orders of magnitude higher. Why not pursue a feedstock that will not take up our ‘normal’ agricultural land (for food and such), with the potential to clean up emissions (CO2 and NOx) and sewage water (Nitrogen) by using them to grow. I am excited for the future of microalgae as a starting point for green fuels. Also, hot water is really low grade power; a power plant would not go too far running on hot water.

This balloon reminds me of Stewie Griffan’s head.

The other stupid thing
This thing assumes it’s using heated water from Iceland.

Why not just use that hot water to run a geothermal power plant…..?

Obviously this concept is more form than substance.

Wow, this is just stupid.

1. Hydrogen from Algae respiration is amazingly inefficient.

2. Using algae to create any sort of biofuel involves a fundamental lack of knowledge about the thermodynamics and economics involved.

One word:
Wind!
One of these things in a mere 20mph wind would be flailing all over the place, dragging and crashing into everything nearby until the h2 leaks out and starts a fire or explosion.

Part of what made the Hinderburg so volatile was the thermite reaction that took place between oxygen in the air, and iron in the paint on the balloon. So saying that the explosion was purely hydrogen is not true.

The Hindeburg did not explode. Hydrogen burns quickly, with an invisible flame.

The Explosion came from the standard Fuel (Diesel?) that was used for its engines. The flames came from the burning fabric that formed the hull of the airship.
