New, open source computer based system modeling tool project. MEDEAS "Modelling the Energy Development under Environmental And Socioeconomic constraints" aims to create a new computational model that will define the future of the energy system in Europe, taking into account physical as well as social constraints.

We are running short of raw materials for batteries already and we have barely just begun to start replacing the 1 billion light vehicles on the road today.
"If automakers can't get battery cells and battery makers can't get the minerals they need to make them, the downward trend in the price of lithium batteries could be interrupted. That could delay not only the rollout of individual new models but also push back the time when electric vehicles reach cost parity with internal-combustion ones.

Anybody have an active mining claim to spare?"

I wonder if resource scarcity will begin to favor H2 as a battery? I'm generally unimpressed with H2 as a battery, but it's better than nothing.

I was thinking the same. They could be building zero emissions vehicles while waiting out until a different battery chemistry comes along.
Audi is starting up a hydrogen project again.

What I don't get is why they don't make plugin hybrid H2 cars. The fuel cell becomes a range extender, the batteries can be much smaller than in a pure BEV. It should be way cheaper than a pure hydrogen car which needs to deliver full power on hydrogen.

Anyway, the condition under which hydrogen can become successful is when clean electricity production starts to exceed grid consumption and storage capacity on a regular basis. 'Free' electricity justifies electrolysis. But we're nowhere near that yet.

*There are at least eleven different battery chemistries available,plus hydrogen fuel-cells.
*The Andes Mountains salt flats are full of Lithium.Also the world's oceans.
*What's the problem?

If we run out of wood and tin, that would be a problem.

There's no such thing as resource scarcity. If a resource becomes more expensive than we like, we move on to a better alternative.

Potholer54 disingenuously points to his discussion of interglacials and says (paraprhasing)"He's either talking bout the leading edge or the trailing edge but noŚ he's talking about both!" I don't have time for that.

Unfortunately I can't find a direct link to the cyclone video. You could look at it and then close the tab when it's over. Would you do that for me?

"Science requires an exacting precision with language,of which Ben lacks command." Here're the links he provided today;

They use exacting language. Journalists popularize them.
*fact-checker isn't something associated with science publication.Science journals employ graduate researchers,veteran Ph.D.s,and veteran post-doctoral experts,in the specific field of study.
*CMEs are plazma:electrons,protons,atomic nuclei.They're just charged particles.Due to latitude,longitude, Carrington 27-day rotation period,and Parker spiraling,when observed,their orientation upon intersection with Earth cannot be predicted.By anyone.
*Also,the field strength of Earth's magnetosphere is a function of latitude.It's 15% weaker at the poles.
*Asteroids are orbiting rock,leftover from the accretion disc which formed the solar system.They have nothing in common with CMEs.
*Gamma-ray burst can sterilize Earth and is a great concern,but nothing we have any control over.
*There have been 800 magnetospheric polarity reversals in the past 160,000,000 years.
*None of these events are associated with extinctions.
*None of these events are associated with cosmic ray bombardment.
*Transitioning into a polarity reversal is no guarantee that a reversal will even occur.
*Earth's geologic record has many accounts of polarity 'excursions',where the field partially reverses,then 'jumps' back to the original dipole orientation.These events cannot be predicted.By anyone.
*I've yet to see an article which attributes extra-solar system-sourced asteroids within our solar system.Parts of Mars have been blasted off and have hit Earth and the Moon.
*As to ice-ages:the language is:
----------------- glaciation
----------------- glacial
----------------- deglaciation
----------------- interglacial
----------------- interstadial
As per Potholer54's reporting,Ben Davidson has no command of the language of Glaciology.It's not a criticism,just an observation.
*If something's that important,you make the time.
*If you can link to the cyclone video I'll look at it.

strange cyclone

I GOOGLED strange cyclone and it offered an article about Cyclone Kenneth which struck Mozambique.A strange place.A strange time of year.And unusually strong.
*Also Cyclone Leslie.
*There's no historical precedent for two cyclones to hit Mozambique in the time interval as seen between Idai and Kenneth.
*Tropical Storm Pabuk struck Southern Thailand at a time when no storm has ever hit (January,February,or March).
*Hurricane Lane became Hawaii's wettest on record.
*Tropical Storm Olivia became the first on record to landfall on Maui or Lanai in mid-September.
*All 'black-swans.'
They couldn't possibly have anything to do with climate change.

I've never seen a hydrogen fuel cell vehicle up close and personal,but it could be,that all available space in the vehicle is already taken up with the fuel cell apparatus,leaving nothing left for even a modest battery pack.
