  1. Once the tyre is off, feel how thin it is on that worn strip. Scary.
  2. The new 1200 has to be a cracking good bike. Shame about the weather we're currently having. ☹️
  3. Well I'll be. I am also in Surrey, near Weybridge and have a FireBlade and SP-2 (and a few others).
  4. Hydrogen powered trains is a stupid idea. The do not need a mobile power source as they can suck it up as they are moving. Why create a problem that doesn't exist. That's what really worries me, that those in charge get so caught up in the popular trends that they don't see the obvious solutions and even even problems that they then apparently solve. Utterly stupid.
  5. I think everyone is aware that there is room for improvement in the production of materials required for current battery technology, but it IS and will continue to improve with enormous research being conducted to reduce the requirement for those materials that create such objection and that's the point about batteries, the technology is changing, improving and ultimately they're re-cycleable which can never be said for fossil fuel despite your humorous point made earlier as of course the way we are currently deforesting the planet means there will not be the vegetation required to make more oil for use in a million years or so. So, however you want to describe your dislike or, or concern about batteries, how does Hydrogen power solve the battery problem when they still require batteries? Something of a rhetorical question as there is no current answer to this debate. The world does still require personal (and commercial) transportation. Reliance on fossil fuel HAS to be eliminated (or we wait until it runs out which leads to the same problem) and you want no batteries, so what's your solution because Hydrogen fuel cell power ain't it.
  6. Battery hatred is a big thing. Really. I come across it everywhere and if memory serves me correctly you've been pretty vociferous in condemning them. Even in your post above you complain about the damage done due to mining their raw materials. But the reality is there is no great problem there with plenty available for all the batteries we'll ever need - as long as we re-cycle and that's another issue. It is possible, but not enough is being done due to there being insufficient obvious profit and "there lies the rub". Sadly it's still all about money. I wasn't trying to say it's 100% Hydrogen or 100% batteries. I did state I see Hydrogen as possible for commercial fleet usage, but there is no getting away from the fact that it offers no advantage for cars over just batteries. At least, none that I've yet heard. Trains are not a problem. They are already largely electric as it is possible to feed them the required power from overhead lines or along the tracks, without a need for mobile energy storage. It's already being done. For shipping, what about nuclear? I was astonished to discover a few years ago that submarines are built around a lifetime nuclear power plant. A self contained module that is installed when the sub is constructed and is never replaced and the sub never refuels in its entire lifetime. The output is electricity that drives electric motors that turn the screws. This is already being done and has been for years, tried and tested. So why not simply apply this to ships. No need then for huge battery storage, nor massive Hydrogen tanks, nor some on-board Hydrogen conversion plant. No new technology needs to be developed. So that's trains and ships sorted. Now, planes. Hmm. Not so simple. Fly less?
  7. Cannot disagree there, except that transportation of Hydrogen is even more problematic than you describe. It CANNOT be compressed to a liquid at normal (room) temperatures, so storing it in bulk requires massive pressure and massive cooling, both of which use up much of its potential energy. Plus it leaks, from anything. Those single protons just cannot be contained by anything larger and EVERYTHING is larger. Obviously this is not a rapid process, but as with the previously mentioned shortcomings, it makes long term storage for Hydrogen impossible. BMW's Hydrogen test cars with cooled and insulated pressure tanks for the Hydrogen would leak to nothing in just 2 weeks. Improvements have come from storing Hydrogen over special materials that hang on to the protons and allow lower pressures to be used etc, but these are very specialised materials and no doubt as 'unpleasant' as the constituents of batteries. Did I say that Hydrogen fuel cell cars also require batteries. 😀 I have yet to hear a compelling argument for the use of Hydrogen in cars. I wish it were not so, but the laws of physics dictate otherwise. All we need is a portable way to store energy that can be released as electricity to drive electric motors. Hydrogen has so many fundamental problems with no conceivable solutions. Batteries however are improving at a rapid rate and will continue to do so with no laws of the universe imposing any conceivable upper limit on their capacity and practicality. But as you say, whatever the method of propulsion, driving will never again be what it once was. 😠
  8. Not really. Once we reach saturation, there would be no need to make 'new' batteries as they're all re-cycled. So no new minerals need to be mined. The only throughput is energy, but everything needs that. Burning fossil fuels can never achieve such balance and will ALWAYS be depleting a finite resource, i.e. it WILL run out. Some people either don't get this or are prepared to shrug their shoulders in an apparent 'not my problem' attitude. Future generations will not appreciate that selfishness. But I digress… Hydrogen or pure battery, that is the question. I agree that for commercial transportation, particularly trains and planes, Hydrogen could be an option with the transport suppliers large enough to have their own plant and also that type of usage only requires a constant source of power. Cars however have very variable requirements and Hydrogen fuel cells cannot produce the massive current spikes that are necessary and batteries can easily provide. Horses for courses as they say. Speaking of horses, back in the day no-one complained about a horse not being able to go for 600 miles without rest. Everyone simply accepted their limitations and planned accordingly. Same for BEVs. We will simply need to adapt to their shortcomings, while taking advantage of their huge benefits. Not only to the environment, but also to our pockets and the convenience of always starting out from home with a full 'tank'. There are cars now that would satisfy 99.9% of everyone's requirements. Who regularly drives over 400 miles per day (cars, not trucks)? For those very few, they'll just have to take into account a stop to re-charge which quite frankly they should be doing anyway after driving 400 miles. So it's back to batteries. They are not the root of all evil and Hydrogen fuel cell powered cars will also need them, so everyone has to accept them. In the brief time that batteries have been seriously researched and developed for cars, they are already twice as energy dense and I believe about 20% of what they used to cost and there are new technologies on the horizon that promise to improve that twofold at least. In 20 years time, things will be very different. In 50 years? 100 years it would probably be unrecognisable to us. One thing is for SURE though. There'll be less oil left, or even none at all. Batteries, hydrogen, nuclear, chemical. It's all about energy and how best to produce and use it in a sustainable way. Perfect solution would be if we could fill up with water, crack that into Hydrogen and Oxygen, re-combine into water which is released back into the atmosphere, releasing enough instant energy to power a vehicle without need of additional battery storage. I agree, that would be marvellous, but currently that takes more energy than is released. If anyone can solve that, they'd be on to a winner.
  9. I don't understand this need to champion Hydrogen as an alternative/better power source for cars. There are massive problems with trying to use Hydrogen. I used to think it was THE answer, but then I looked into it more it was obvious how impractical it actually is. Expensive to produce, really hard to store in quantity, cannot be simply piped around like natural gas, just what is its supposed 'advantage'? Range? No doubt convinces many, but what is currently being touted will soon be surpassed by batteries and more to come with further battery development. How will the range of Hydrogen cars increase beyond what is now offered? Bigger tanks? Better Hydrogen? Ha. Re-fuelling speed? With the latest BEVs and 800v charging, capable of 80% charge in under 20 minutes, is that really a problem? Especially when the majority of cars will only ever need to be charged at home, overnight and never actually take advantage of any rapid charging ability of their car. Easier to find somewhere to refill with Hydrogen than recharge? You're having a laugh or haven't done the maths. There are already more re-charging points in the UK than petrol pumps. They're so easy to implement everyone can have one in their home and commence every journey with the equivalent of a full tank. How many homes will have their own personal Hydrogen production plant? I think we all know the answer to that. Better for the environment? Nope. So the car doesn't use power directly from the grid, but where do you think the energy to produce the hydrogen comes from? Hydrogen production is not a simple or efficient process. It requires a lot of energy and from where is that going to come? So it really comes down to what seems to be an irrational hatred of batteries. Well, as I've said before, Hydrogen cars also have batteries so you're not avoiding them anyway. Admittedly, fewer batteries than a BEV, but with batteries being re-cycled it'll make little to no difference. Does a hydrogen car provide the same aural thrill as an ICE? Nope. They're exactly the same to drive and listen to as a BEV (although to be as fast means more batteries). So I say again, just what is driving this desire for hydrogen (with battery) power rather than just batteries.
  10. Completely agree. I am a firm believer in cutting pollution (of all sorts) and switching to electric powered vehicles is a good way to help with that (whatever some may say), but Climate Change? Nah.
  11. Well I don't know about the basic Thruxton, but the Thruxton R (as pictured above) is incredibly light handling and certainly does not require "a bit of effort to get it round the corners". It is admittedly not a lightweight bike, but that is completely at odds with how light it feels to actually ride. What! Only 2 bikes? 😀
  12. Good choice. Had mine for over 4 years now. Reminds me of when I first got into bikes and built a couple of Tritons. Only this is MUCH better.
  13. I always like the Arthur C. Clarke quote:- "Sufficiently advanced technology is indistinguishable from magic"
  14. I actually think the best potential new tech. is from QuantumScape, a Bill Gates-backed startup developing next-generation batteries for EVs. They've found a way to use no actual anode but Lithium is deposited there during charging and completely removed when discharging, so each cycle puts the battery back to its initial state with no possibility of build up of contamination and/or dendrite growth that over time kills a traditional Li-ion battery. Effectively the anode is created afresh during each charge. Obviously a way to go before we see it outside the lab, but it certainly looks promising and Bill Gates is not known for backing duds.
  15. That's just the stock market isn't it. I agree, utter madness.
