When I was a kid ,seems like only yesterday, only superman could see thru walls. Can't quite remember which Marvel hero could read stress but as with much scifi many scientists and physicists found their introduction to these concepts at an early age.If you live long enough some ideas eventuate. First particle accelerator built ~1945. Now we see a metal producer obtain - " beam time at through the Industrial Applications Program at the Shull Wollan Center—a Joint Institute for Neutron Sciences. " As a time-of-flight diffractometer at the world's most intense pulsed, accelerator-based neutron source" sampling volume of 2-600 mm3 " In extreme cases, VULCAN has the ability to study kinetic behaviors in sub-second time frames.
This will be included in data noise from all connected vehicles. Of course the road maintenance authorities will be happy to get the app.
The discontinuity as see it is the use of synchotron or particle beam microscopes as well as other real time imaging tools over the last five years or so. These tools have been about for several decades but only recently has the technique been attempted for the lithium secondary cell studies. By looking inside a cell as it charges and discharges researchers can see especially dendrite formation and other structural changes that have previously taken months of accelerated ageing to understand the end result. These tools require sophisticated understanding and for commercial application or public interest there needs to be a strong case. As both these requirements are easily met for Li cells and researchers are active in the area we can reliably predict massive improvements in both longevity and capacity over the coming years.
Could it be $10% more than existing 48V offerings? I'd like one of these in a drag race lawn tractor and I'm sure the neigbours would appreciate a Sunday sleep-in.
time frames for industry mass production still remain a human scale limited logistic and development problem. The problems are often unforeseen and can only be resolved at humans pace. I think we have become for too used to seeing apparently instant results in our ordinary lives while things continue to take the time they take remains constant. On the bright side, the available technological tools and the understanding of their application have been breaking new ground in battery development and delivering at the exponential rate. This is the important change as without solid science, the factories can only produce 'second rate ' no matter how fast or how many it is the understanding that will deliver the results we want and that understanding is occurring much faster than the doubters want to believe.
I would guess @ $25K it's not a new engine but a scrapper. The new is to say new to rail application. So is it a diesel electric or something historic like a starter motor or mail car. Either which way it can do no harm and as a university project shared amongst the undergrads? will be a nice little demonstration project. The diesel pilot/ ignition H.D. engine with hydrogen delivered thru air intake is not new but interesting.
With thousands of mattalurgists working and researching and new tools and large markets for it should be no surprise that important new products are arriving at an increasing rate. Hasn't been a priority for manufactures and the disincentive was that breakdowns made money and incresed demand. But so important for longevity in lpg and probably many other engine applications presumably the D.I. petrol problems are of a similar nature. Although to my outdated understanding the problem with heat affected alloy softening is a problem related to poor engine tuning (lpg). That becomes exacerbated when high fuel economy targets are prioritised (all). It should have even bigger uses for other non ice applications.
I wish it was clearer whether this group of co's manufactures at the cell level. I'm sure that cell manufacturing is not mandatory for their business model.
20% loss would be substantially higher than expected. Compression and storage plus stack losses will likely double those losses. The cost and life of catalysts will be important but presumably this method will permit swap out and upgrade. Solar pv installations are being suggested to prioritise hot water over grid export for economic reasons. Apparently it is preferred over solar thermal. Those lucky enough to have larger pv available would often find BEV the better option and the economics might stack even if it meant some double handling thru a large(ish) stationary battery if the car was not co located in the daytime.
I'm thinking that the test results quoted were those applicable to county water treatment plants. Definitely no tests required for radioactivity. From recollection that included when they accepted standard discharges from nuclear (power) plants. E.P. would likely be referring to regulations applicable to the N plants own monitoring .
I like paradoxes. Aussies have nothing if not a sense of humour . A Dingo fling would be just the ticket esp considering our Scottish expat communities. Ding golfing sounds too presidential.
edit:" would either colonise or introduced from" culture. Mississippi & Missouri river systems. E.P.. The authors were not at all focused on the nuclear aspect the emphasis being on ground sites of the more common hazardous substances but also looked at some downstream aquatic aspects. The particular text and studies could be (are ) early investigations some sites studied were closed in the 50/s60/s so there had been considerable time elapsed which allowed longer term conclusions. I could only guess the date of publication and have no knowledge of test requirements as they stand today. It would seem to be an interesting line for investigation. I will try and recover re read and report back. Testing for radioactive materials I would defer to your understanding and assume it to be long well solved. Recently we heard of and have seen methane sensors costing a dollar or three and data loggers capable of running on parasitic energy from natural and broadcast frequencies that can be read or downloaded via near field communication. At the same time as that achievement we see the current administration cancel monitoring introduced by the previous admin for (especially those associated with hydrocarbons from oil?gas?) emissions that would have been of interest to the oil and gas industry as well as essential for quantifying site,state, country and global emissions.
I read in a Uni text book (since passed on) on bioremediation primarily of oil based but various other toxic substances describing naturally occuring organisms that would either colonise or could be introduced from a bio'warehouse' . Great read but the authors went on to describe the regulation of nuclear waste into the Missisipi river. While many substances have limits on discharge from water treatment including sewage plants, the point made was that there were no standards for radioactive materials discharge and no tests were made even though it is the drinking water supply to 'more than a few'? people. When the A.N.S.T.O representative was speaking at it'slicensing hearing for Lucas Heights, he/she was asked on the evacuation or notification plans in case of accident. The reply was "None , that would only frighten the local residents" There were other clangers relating to reprocessing inn Argentina that played out as false and a string of errors in the build. We have a substantial fly in well resourced and highly paid lobby group ( if I was a right wing politician I would call them 'Rent-a-crowd.) here in Aus currently for the nuclear waste disposal, nuclear power generation promoters and believe it or not the debate is being put up to the merit of Australia aquiring nuclear weapons. This is an example of a string of poor regulation and a cover up denial culture or mentality and I would say that the whole nuclear industry has a very poor track record. There is just no way you can trust these people when a rusted on atheist cannot say it better than borrow from the scriptures. Acts 9:18 “And immediately there fell from his eyes as it had been scales: and he received sight forthwith
R.E. and storage costs are here to stay again we find the opportunities are mostly still evolving. Nuclear alone doesn't make any difference in that respect. While I agree with the thrust of this report On a country by country basis would question the contribution from forest removal and fires especially the avoidable components from development agriculture. Wildfires and hazard reduction are not so easily resolved. I seem to remember that uncontrolled intentional fires related to palm plantations and clearing in Indonesia emitted as much 50 to 100% + of emissions reduction efforts that year.
wondering what to do with all the (Billions of tons?)of left over CO2? Maybe make crushed diamonds for these/?:Organically synthesized porous carbon shows “exceptional” potential as Li-ion anode material http://www.greencarcongress.com/2018/06/20180626-opsc.html but they will have to compete with this mob: "Hair / Ashes to Diamonds in Australia Memorial diamonds are forever. LONITÉ turns human hair and cremation ashes of your loved one into diamonds in Australia. Cremation diamonds are certified by GIA. Every essence and provenance of your beloved is captured forever in the unique LONITÉ memorial diamond from ashes." Carbon[C] accounts for 18% of the human body; diamonds are crystalized carbon. Memorial diamonds are genuine diamonds grown by using the carbon contained within hair or cremation ashes. LONITÉ's London branch office makes it possible to turn your loved one's ashes or hair into close heart diamonds in Australia. Nitrogen [N] accounts for 3% of the human body, which gives the diamond a Naturally Amber™ colour, varying from light yellow to deep orange. Purely Colourless™ diamonds are created by removing nitrogen [N] from the carbon [C]. They are keen on steam reforming from NG. Thinking -USA- TRUMP Anyone?
A couple of points. The further from centre the weight as I.E. tyre, the more it contributes to rolling inertia which is costly in both acceleration and decel. This design is not bad in that respect. The four motor setup would reduce the load to each so expect 300000k's at the same time maximising regenerative braking performance. The large diam motor rotor helps simplify design and increase torque. Unsprung weight is definitely of concern but suspension workarounds and slower speeds as in city work are not as demanding as for performance applications. Since this is early for commercial? production there will likely be weight savings to be had with later gen. For now slowly slowly makes sense.
The study refers to domestic gas appliances but there are industrial applications that are well suited to efficient efficient combustion or other. These could include turbine generators and domestic or small CHP. The gas infrastructure and it's capacity for storage has benefits as both backup or alternative energy source means overall reliability is enhanced. The system infrastructure can also absorb excess renewable electricity even if not at the highest efficiency, If renewable H becomes widespread eventually , and the infrastructure is upgraded it would seem possible or even necessary as a complimentary piece of the clean energy puzzle.
While this is small scale in the context of Japans energy requirements it is appropriate to remember large scale generators are unable to meet the need for distributed aggregated supply. I am heartened to think that schemes such as this will help eliminate proposals for massive fossil fuel sourcing of Hydrogen. It is obvious that the current plans from fossil fuel industry is to supply 'clean,' 'low carbon'or 'zero emission' Hydrogen fuels to well heeled and gullible consumers and govt's well practised in deceptive behaviour. Australia sees itself as renewable energy (Hydrogen) supplier to Japan if not many other countries but the gov't here supresses and talks down renewable generation while hard selling coal seam and shale options as well as subsidising the coal(and oil) industry with public money.
There should be a way to integrate and substitute the power cable at the suspension attachment so to avoid the need for cable to flex as the suspension travels.
Two motors is different. I wonder how they are arranged. Is it possible to operate with one disconnected or are they constantly paired? What purpose does the arrangement serve? Efficiency or practicality? Coupled with two speed transmission in these vehicles with large power swings there would seem to be some possibilities for energy efficiency and durability gains.
Two problems withthis approach. 1: with Delerium Tremors in the white house supporting climate deniers and tax avoiders why would anyone pay any levy for polluting? That means we are $60 per ton behind off the starting block. 2: The same $60 premium would make battery storage or electrolysis amongst other R.E. options already viable and a mare sustrainable option as these can be understood to be decreasing with scale.
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.
