There seems to be a lot of interest and need for these 'greener steel industries.The different types of steel have different feed stocks including a carbon source. One source being (recycled) plastics, tyres etc. So the talk is of gradual change. These improvements should be even more applicable to Alumina as a consumer of R.E. and hydrogen storage. The carbon footprint could be lower as it is not required for smelting. Watching with interest.
There are lots of problems with the hub/ wheel motors including cables movement following suspension that need more work. I think it should possible to bring the power through structural electrically insulated route effectively eliminating that part of the cable run. Love the twin motor pic. Note the twin motors integral to the suspension pivot that should enable power cable connection opportunities. One possibility gleaned from the pic is to have the motors fixed and the gear train (motor drive unit) pivot on the intermediate or idler gear axis. It is easy to see how the basic layout is giving benefits to fixed wiring, motors on seperate axis allowing more size and ratio options and the outputs are narrow so smaller dropshaft angles. The 3 axis would be motor, idler/suspension pivot and output drivesaft/wheel. The wheel motor cables have a lot movement to deal with .
I never knew the Fiat 500 came as diesel. Oh now I get it it's like a cuddly toy image to make us feel all warm and fuzzy. Seriously though if it helps reduce harmful emissions from existing vehicles ( which were in many instances illegally sold in the first place) then it is hazard reduction and may make some difference.
Of course it is not as good as 100% from battery tech and the question that should be asked is where does the ammonia come from? in the real world.
I think we are led on these deceptions by lobbyists or advertising people that have vested interests in seeing companies profit margins either retained or increased. We live in a world where half of inventions are obsolete before they hit market. That is a worrying thought. But the coal gasification and carbon storage technologies are not new technologies and they have a terrible failure rate. They haven't got a succes rate in terms of carbon reduction or sequestration at any scale. Kawasaki H.I. may well be in the buisness of transporting renewable hydrogen according to the glamour postings and spruking aimed at investers and public relations but when they get involved with this behaviour it transgresses credibility. Linc energy tried this (underground ) in Queensland a few years ago and the resultant mess has caused permanent serious damage. The taxpayer is once again left to pay for the clean up.
It's just a political fix. The 50+50 m($100,000,000 .au) from state and federal govt's will make a few hardliners and gullible fools as well as the technocrats at C.S.I.R.O. happy for a few minutes as they wil have a bucket of money to play with. It will Make the Japanese politicians look good for possibly the rest of their term in office. It WILL help Kawasaki develop their H2 transport technology and possibly be a proving ground for the CSIRO Ammonia /Hydrogen transport concept. Almost everyone will look very pleased with themselves and the media attention they seek. But it isn't likely to be low carbon compared to just about any of the alternatives being considered globally. The low carbon bondoogle is simply tha tthe .au and .vic gov'ts can claim 0 carbon and the Japanese as well. So It would seem to be just what the doctor ordered for solving international carbon emission targets while satisfying the climate skeptics demands for fossil fuel industry assistance from taxpayers. Lets not pretend this has anything to do with either low carbon , low cost reducing global warming, or even providing long term employment. It'simply politically expedient to defraud the ignorant while looking good and lining your pockets. What's not to like?
another great site this insight on the recent autopilot problems https://arstechnica.com/cars/2018/03/tesla-says-autopilot-was-active-during-fatal-crash-in-mountain-view/ https://arstechnica.com/cars/2017/08/report-tesla-is-bleeding-talent-from-its-autopilot-division/ https://arstechnica.com/cars/2018/03/tesla-stock-falls-12-after-ntsb-announces-fatal-crash-investigation/
Court action on the basis of this fraud is being defended by VW. While the E.U and U.S. court actions have been successful VW 's lawyers claim they are not breaking A.U. law.
Very interesting comment E.P. The only clue here is that this particular site stopped taking landfill in the 1990's. Two scrubbing techniques mentioned in the following PDF. Laboratory analyses is required for detection and quantifying . http://www.xebecinc.com/pdf/e_white_paper.pdf Siloxanes can now be found in every landfill and digester in North America and Europe. Thirty years ago this would not have been the case. Newer landfills are tending to show higher concentrations of siloxanes, reflecting their expanding use in more and more domestic products. The siloxane problem can only worsen. Still, many older sites with lower siloxane levels can be tolerably managed with creative maintenance schemes and modified operating practices, but even these solutions come at a cost – for instance, one trick to cope with siloxanes is to reduce capacity. Xebec estimates that approximately one third of all landfills using internal combustion equipment to generate electricity from gas would have very good economic reasons to consider investing in a dedicated siloxane removal system. A Siloxanes are non‐toxic silicon‐bearing organic compounds that are added to many domestic products such as deodorants to improve their texture and feel. Siloxanes are volatile compounds that evaporate and migrate out with the landfill and digester gases to be combusted either harmlessly in a flare, or harmfully inside internal combustion equipment. When methane and other hydrocarbons burn, all the combustion products are gases that exhaust easily from the system. Silicon‐bearing organic compounds burn as well, but the combustion product of the silicon part is very fine crystalline silica, which is a solid. Silica in its granular form is better known as sand. The crystalline silica from burning siloxanes sticks to hot surfaces inside internal combustion equipment, coating them with a thick, hard, abrasive layer that also insulates these interior surfaces, allowing heat to build up where it should not. If the concentration of siloxanes in the landfill and digester gas is high enough, this accumulation of silica deposits can severely affect the maintenance intervals of the internal combustion equipment. There will be much more downtime and many more parts to replace —operators can be faced with full head and turbocharger change outs, or engine rebuilds after only 9000 hours of running time instead of 25,000; spark plugs and oil changes may last as little as 400 hours
Doing what they do best pure design to warm the heart.
If the reality is as impressive as the sketches this should prove popular luxury vehicle. The final weight will be important and we know that the company has had a strong focus on body weight reduction but one problem we are seeing universally working against efficiency and weight savings is the proliferation of electrical and electronic systems . Despite progress such as CAN high speed computing miniaturisation finite element analysis and high strength lightweight materials, starry eyed consumers are encouraged to expect more the gadgets and interactivity, infotainment ,connectivity etc that we used to expect when we arrived at the office. Some say all these distractions are a hazard. One thing is not disputable It ups the cost and weight. A vehicle with these specs in a bare boned spartan or track ready configuration would be very interesting to people who focus on the practical with no need for more gizmos in their life. It goes without saying a version with these qualities would go further handle better, be less of a muddle, cost less, last longer etc One to watch?
This sounds really interesting and a surprise to see HD 'getting it'. I wonder what the thermal wicking system looks like and also where they see the machine and riders combined *roll centre is. It is not common to hear reference to roll centre in m/cycling. Ideally to keep the belt length constant the motor output should align with the rear suspension (swing) arm pivot which is also very low for CG considerations. That could be possible depending on how the rest of the vehicle systems are positioned. Conventionally CG sits below the rider well forward of that pivot
Something like pre WW11 (Chev) splash feed bottom with pressure feed top end engines that we see in so many small engines today? The idea seem to be to continue the move away from conventional semi-imersed gears without using conventional pumps as such. Surely any splash shares the same physics with an ideal pump such as centrifugal. It would seem that to reduce drain down and supply good cold start lube with the low viscosity oils we see in the market an electric pump could be utilised for cold start. Using lower viscosity oil would seem to be an important contribution to reducing drag in every friction area including bearings seals as well as the viscosity fluid impact losses. The take away idea is not new but the specialised activity of putting in numbers during the design process is.
A very important big step too. It may be called for in black spot glitches or snowed out when" but it wasn't - or was - there last week " wont work.
MB/D have been consistently making steady progress bringing real e-trucks to market so have the practical knowledge. 200 klm is a big step in the right direction remember this is for trial in Europe short haul. It would seem that the versatility of open platform means that when the expected improved batteries chargers etc become available that the basics will have some track record and the usual glitches will be better understood. It's a bit pointless to criticise near reality with some wish list expected further on when every journey starts with...
The electric vehicle ghg red and ownership costs are both shown decreasing over time while the diesel and gasoline vehicles are expected to do worse on both emissions and cost per mile over time.
The study shows the levelised cost per mile as cost of ownership while not considering rebates, parking traffic zone or lane use exemptions or other legislative benefits. Working from this abstract I see no mention of maintenance costs either. It might be more accurate to say this is their projection of various costs excluding ownership given that it does not attempt to. While it would be difficult to quantify across the many markets, it is a very important consideration they appear to have overlooked. If they truly are interested in facilitating the solutions to global warming as a priority they might also advocate for financial penalties for pollution and the suite of exemptions as applicable to ZEV's . We know that they represent and will where possible defend the reputation and economic interests of the members both individual and corporate as is their purpose in the same fashion as every other industry focused body. We should understand that the members are derived from the chemical and associated industries and will tend to be pro active ( if not they would be less likely to remain involved) We can see how this will inevitably lead to bias. The chemical industry also represents battery makers and other competing technology I.E. ZEV interests and so can make claim to be unbiased. How well can you read the tea leaves?
Of course there are alternatives that don't require fossil fuel extraction or mining and spreading toxic nuclear materials but the powers that be want to keep the status quo including the nuclear and other armament industries.

I'm so sick and tired of all the fake news that my doctor has ordered some time out. Being a good patient and wishing so much to comply the kids have thrown in to send me on a round world trip fishing and hiking in the wilderness. I'm sure you'll want to know where the best fishing and hiking spots away from the paparatzi (is that like press azi?) who have been distracting my game Mar-a-Lago. I can tell you the intrusion into my personal affairs and those of members of my associates has become so problematic that even the $200,000 initiation fee which is so obviously an incredible bargain may need to be changed. I can't say whether it will be up or down - that will depend on whether people still want membership after my meeting with god gets reported by the fake news as collusion with the devil or Russia or something. But we are working on that - we may need to lock them all up for a while until they can see reason sacking them has become ineffective and soon no one will have a job and that would be bad for membership and bad for the economy.
It may take these amateurs a while to get the results they are looking for. What a joke -Artificial Neural networks FFS! Why don't they follow the clean green fossil fuel industry experts and get with the program? I can tell you " Don't worry," "It's fake news." https://www.thelocal.de/20180131/vw-hid-devastating-result-from-diesel-exhaust http://www.bbc.com/news/world-europe-42858668
After much redaction of bad words etc lets see how this goes. "It may take these amateurs a while to get the results they are looking for.

As valued subscribers to my daily thoughts I can say I have narrowed down the options to two secret fishing spots and one wilderness experience theme park. Areas 61&67 are fishing hot spots with so many fish I hardly need a lure but if I get bored with catching all those fish I can just throw any lure in and it will glow and flash even without the battery . How goods that? http://radioactivechat.blogspot.com.au/2013/10/Food-Label-Will-Tell-You-If-You-Are-Eating-Fuku-Radiation-FAO-Major-Fishing-Areas.html After that I will be meeting with my friend Vlad who like me enjoys nothing more than a hike thru the re - natured wilderness park for some organic wild food gathering. I can't tell you right now where that is for security reasons ( and difficulty getting visas) we are keeping this very quiet . https://aeon.co/essays/ukraine-s-berry-pickers-are-reaping-a-radioactive-bounty.
No magic - it's not the magic kingdom- but you can see it from here.
Proposals around delayed power or synchronised schedule have suggested prioritising devices. Either by programmable device including V2G for large battery devices or I would suggest a simple device able to recognise the grids condition in real time will also have an adjustable set point for switching. While the variation in manufacturing tolerance on its own will be of some help, I.E. there will be some spread, when aggregated across many different devices from a variety of manufactures and with the possibility for setting the switching point, I would't think that the grid oscillation would be as hard as first glance may suggest. The other consideration is that in some countries and areas many premises have wireless 'smart meters installed and of course changes to meters on new installations or if vehicle charging is added will likely be required. The average house will need >2x supply. I guess the whole point of the term 'smart grid' as a work in progress is to foresee and adapt by various means for changing demands (as it must today) more efficiently using the existing infrastructure as well as cope with higher expectations and demands.
