Guest Blog: Racing Memoirs of a Lifetime Lotus Seven Enthusiast

Editor’s Preface

I’ve set myself quite a challenge introducing this weekend’s Guest Blog, because what follows is an utterly, charming and endearing account of one man’s journey with a racing car, a Lotus Seven no less. Mr Tony Pashley tells us about his life as a Lotus Seven enthusiast and how he realised his ambition to own such a vehicle. His account takes us through several decades (Lotus having been around for seven) with many trials and tribulations, and much joy not just with the car, but also his family and friends.

No comparison with what one might experience with the modern day Electric Vehicle, with all manner of complex gadgetry and controls, that you really can’t take to pieces yourself. At least, for now, we still get to drive them, whereas one day in the not-too-distant future we’ll be relinquishing such pleasure to an AI. As Tony rightly points out, the sheer delight of being a dedicated petrol-head will soon be a matter of folklore – something we live to tell our own, or others’ grandchildren. For now, I leave you with a gem of a tale. My very sincere thank you to Tony for providing us with such a fabulous read.

The Dream

Sometime in the mid-sixties, when my father first took me to see motor racing ‘live’ at the local circuit, we saw an event for a category called Clubman’s Cars: tiny, minimalist machines, and the most popular at that time was the Lotus Seven, a concept dating from the late-50s. I was fascinated by them: although only modestly powerful, their very low mass and racing-car underpinnings gave them a real-world performance to match, or exceed, very expensive and exotic models to which I could never aspire. They appeared to be driven by ordinary mortals of seemingly-modest means. The ideal machine, then, for the impecunious enthusiast: to use as transport during the week, then race at the weekend. Even at that impressionable age I had no aspirations to actually race, but a Lotus Seven looked like a load of fun.

The founder of Lotus, Colin Chapman, had a design mantra: ‘just add lightness’. Less weight leads to better performance and responsiveness, less stress on components (which can then be smaller and cheaper) and better fuel economy – a smaller petrol tank and a further saving of weight!

Some years on, after I’d left home and begun driving, the car was still being made and developed (and still is today), by Lotus’s former distributor – Caterham Cars, in Surrey – under the name of ‘Caterham Seven’. But I couldn’t have one: it was not until revisions made to the cockpit design allowed my scrawny six-foot-two of muscular understatement to actually fit inside that I could seriously think about ownership.

The Build

At the time I finally took the plunge, there was a 12-month waiting list for a ready-built car, but a fairly popular option was to buy all the parts unassembled and put them together at home. More Meccano than Ikea, and the instructions, however mystifying in places, were, I was assured, more copious than the Swedish offering.

And so, armed with a bank loan, I ordered the first consignment of parts and cleared all the junk from my lock-up garage. My previous ‘batchelor hobby’ had been Hi-Fi, but my last major purchase in the pursuit of extracting sounds from pressed vinyl arrived on the very same morning as did a truck bearing cardboard boxes filled with shiny new car parts, nuts, bolts and widgets – and numerous items I couldn’t identify. A new obsession had taken hold.

I knew a good deal of theory (or so I thought) but had little practical experience, so the learning curve was steep. And working mostly in a garage with no mains power, it was a project for weekends and holidays. My father would come to stay and help where he could, offering encouragement or an extra pair of hands and making cups of tea.

Including a few weeks taken up with sorting through boxes, just staring at parts wondering what on earth I’d embarked upon, I spent the better part of a year on the assembly; aside from it being new ground for me, I was spreading the cost, and adding some improvements and personal touches to the basic machine.

During build with Dad

By the time I actually had the car running, it might have been as quick going for a ready-built car, but I’d not have learned how it was assembled and maintained, how it worked – and not had such a sense of satisfaction.

There was a special accreditation process for ‘amateur-built vehicles’ that were to be used on the public highway (but a much less onerous one then, than it is now). I passed this comfortably and one memorable day, with my old school-mate-from-the-age-of-eleven in the passenger seat, I embarked on the car’s first lap of the neighbourhood block. It went, steered and stopped on demand; it felt wonderfully controllable, a tactile extension of hands, feet, mind and backside. Weighing in at just over half a tonne, its performance was – how shall we put this? – sprightly, and it was quite loud. Life would never be quite the same again.

Cleaned, polished, ready-to-go

I briefly had a try at competing in ‘sprints’ – that’s time trials, racing against the clock rather than battling wheel-to-wheel with other drivers. I enjoyed the discipline, but you only get a few minutes driving during an event and I didn’t really care about being faster than anyone else: I just wanted to enjoy the art (or craft?) of driving and – later on – minimalist touring holidays on the quieter roads of continental Europe.

Driving on racetracks (in non-competitive events, ‘just for fun’), particularly abroad with a holiday tacked on, became all-consuming for a few years. One particular season, I rather recklessly spent everything I’d earned in the previous year: thirteen days on track, half-a-dozen short holidays and many an hour spent on cross-channel ferries. It wasn’t entirely ‘sensible’ but it was blast.

Taking to the track

After many years of being a fairly circumspect and dependable driver (other owners would allow me to drive their cars on track), my rising confidence, and perhaps a loss of concentration, got the better of me. Putting a wheel onto the wet grass on a Grand Prix circuit, throttle wide open in top gear, saw me in an irretrievable spin and bouncing off a concrete wall. In one sense I was lucky to hit that wall: if you hit the barriers you have to pay for them!

I’d previously only managed to inflict minor cosmetic damage to my car, but now my pride and joy was bent. Rather badly. I was unhurt though and, with regard to driver safety, the integrity of such a minimal structure and exposed cockpit was truly impressive.

The car had to be repaired. It had become a part of my life; a small part of my father’s life too. And ownership and use had gained me the new circle of friends I had struggled to find ever since leaving home (friends I’ll now have regardless of continued petrolheadedness). Some might say that car was the closest thing I’d had to a child – or even a beloved pet – but aside from many years’ worth of adventure, the interest and the connections had brought me a good deal of paid work.

The Rebuild

Some of my better-heeled friends had suspected that I might be struggling for funds and, without my prior knowledge, had a whip-round to help out and ensure that I could rebuild properly and begin without delay. They wouldn’t tell me who had actually contributed and I only knew the total sum collected.

One friend brought the car home from Europe on his trailer and another cleared space for me in his large, but very crowded garage-cum-workshop, and inspection and complete disassembly commenced.

A more conventional, steel-shelled car might have been written-off with repair either too expensive, too difficult or simply unattractive. But aside from any personal or emotional attachments, my Seven had, repair was a practical proposition, and – given that a lot of the labour would be free – rather cheaper than replacement.

Being small, light and manageable, and constructed more like a racing car, taking it to pieces was the quick part. Having maintained the car myself for so long, at least I knew what (almost) everything was, where and how it was fitted, and what it did.

Stripped chassis

Beneath its largely non-structural bodywork, the chassis is a space-frame made of steel tubes, brazed together by hand by a process sometimes referred to as ‘bronze welding’, which produces a sound structure without unduly stressing the material with excessive localised heat. It also makes it comparatively straightforward to repair. But not by me: this was way beyond my skill level. The frame was rebuilt by the original makers on the very same jig upon which it was first made, twenty or so years previously, and overseen by the same man.

Of the parts that could not be reused, most were of a single material such as aluminium, or could be disassembled to that state, so there was a reasonable prospect of viable recycling for them.

Oddly perhaps, the rebuild took twice as long as the original build, not least because I wanted to do everything more neatly than I’d done before and try to make every likely maintenance task easier in the future. I wanted to be proud of all the detail work when it was inevitably inspected by fellow owners.

I also wanted to check all of the wiring; I’d had no electrical problems in the past, but time and weather do take their toll on wires and connections. Even a small and simple car has a staggering amount of wiring if it has lights, indicators, regular dashboard instruments and other bits and pieces needed for road use. The wiring loom had originally been supplied fitted to the chassis, but now it was a daunting mass of loose cable and plugs sitting forlornly in a cardboard box. I spent one Christmas cleaning, checking and labelling every part and connector. Most of it was fit to use again, a few parts were simplified or renewed for reliability, but reinstalling it was a lengthy task, and pretty hard on the fingers.

The wiring loom

An engineering-minded friend cajoled me into a few improvements along the way and called in favours from fabricators for a few custom-made parts. But that all took time: one such artisan was busy making exhaust systems for a Formula 1 team at umpteen thousand pounds per set, so my freebie fabricated component had to wait its turn…

Chassis assembly

By this time I was in business for myself as a design consultancy and I’d also become editor of a magazine, which meant that work was fairly regular and intense, but periodic. Thus, I could devote decent chunks of time to the project, commuting to the garage – which was good as I was becoming worried about outstaying my welcome there. The car eventually came home with me for some details to be finished and my generous host and his wife are still two of my best friends.

Nearing completion

Now, almost completed and looking better than ever before, the car has had disappointingly little use since then, real-life issues having interrupted of late, such as my supportive Dad now needing help himself. For some time, he’d not felt well enough to join me in any motoring adventures; but I’m sure he found joy in seeing me enjoying things he would love to have done for himself.

The Reawakening

There are a few little projects left to consider for my Seven. Electronic management for its essentially old-fashioned engine, could improve it – and make it more efficient fuel-wise. Then further steps to make it quieter: I’m well past the age when driving a loud car gives me a buzz.

I built my sports car long before I could be accused of having a mid-life crisis – it was more the kind of second teenage-hood that you can only afford as an adult. A part of me would like to continue while such machines and activities are still tolerated, but there’s so not much left to do that I haven’t done already.

And, to be honest, this is all running against the tide. Driving for pleasure in this day and age – particularly with an internal combustion engine – can be regarded as irresponsible, and even somewhat perverse, though I’ve certainly had my fun. Building the thing did give me a surge of confidence in what I could achieve if I set my mind to it. It’s given me some wonderful memories to cherish, of places I’d never have visited, were it not for knowing I’d have a great time getting there. And I got to drive, spiritedly, on a dozen different Grand Prix circuits; I might be too old now for a realistic prospect of having grandkids, but it would be something to tell them!

A drive in the Seven can be electrifying, and maybe that’s a hint as to what should come next. For me, the issues of weight and packaging might still be obstacles at the moment to a truly desirable, charismatic small hybrid or electric vehicle. But those technologies do have the potential to delight the performance car enthusiast. And given the Seven’s small-ish fuel tank and relative thirst, range-anxiety wouldn’t exactly be new to me!

In the past, there weren’t the clever technologies to improve performance and efficiency, but I’m sure lightness and making vehicles no larger or more complex than they need to be, are important lessons. A modern car is so full of sophisticated fittings that it seems more likely to be scrapped than kept going.

There are some very impressive high-end hybrid or fully-electric machines coming from prestige brands; in my possibly biased opinion, somewhat decadent technology-showcases with almost infeasible levels of performance and shocking price tags. If I liquidated enough assets to acquire one, I wouldn’t have anywhere to live! But with a bit more ‘trickle-down’ of that technology, I could be ready to plug in and switch on…

Guest Blog – Tesla Battery Recycling

In today’s guest blog, Bodo Albrecht, President of precious metals management consulting firm, BASIQ Corporation, puts Battery Recycling under the spotlight and looks at how, the Electric Vehicle pioneer, Tesla is preparing for sustainable End-Of-Life (EOL) disposal of batteries from its range of passenger electric vehicles.

Tesla Battery Recycling – the long road to “closed loop” systems

Electric vehicles (EV) – battery electric vehicles (BEV), to be precise, just won’t die. Even though General Motors famously crushed its “EV1” program in the late 1990s, the technology survived in other icons such as the Toyota Prius Hybrid (which was launched almost in parallel) and, 8 years later, the Tesla Roadster. Since then, not only has the technology broken through the 1 million unit mark in annual sales, it is also increasingly expected that EV (encompassing hybrid and fuel cell variants) will make up over half of all new car sales by 2040 and eventually replace ICE (internal combustion engine) technology all together.

General-Motors-EV1

The trend is driven for the most part by a necessity to reduce emissions and the need to utilize scarce resources on our planet more responsibly. So, naturally, the new technology is under strict scrutiny to ensure that it will achieve what it promises, not just in terms of local emissions but also the sustainability of its entire life cycle.

Vehicle batteries have been, and are still, at the center of this process. Life cycle considerations range from the mining of lithium, the carbon footprint of the underlying logistics of material procurement and component production, the generation and supply of electricity to end-of-life (EOL) solutions. Let us focus on the latter issue today:

Tesla Model X

While early EVs and hybrids like the Toyota Prius had nickel metal hydride (NiMH) batteries, the most commonly used batteries today are lithium-based because of their better energy density (longer range) and the ability to recharge them more rapidly. More precisely, these batteries utilize variations of lithium, cobalt, manganese, lanthanum, cerium, neodymium and other metals; a somewhat different technology employed by BYD, a leading Chinese producer of EVs, uses iron instead of cobalt. Because of the complexity of these systems, efficient recycling technologies are still in their infancy. Li-ion batteries have a life expectancy of 8-10 years meaning that the first Tesla batteries will become available for recycling just about now. But the car was originally made in very small numbers only, as was the Model S that followed in 2012, which is why investments in large scale, industrial size recycling plants will have to wait several years to see a positive RoI. What is more, companies like Tesla are pushing out the end-of-life issue by repurposing their batteries for stationary use, where high performance and quick recharging times are not as critical.

Experts expect that it will take until 2025 until EV batteries will become an economically viable industry for recyclers. This doesn’t mean that recycling technologies do not exist. Early on, Tesla partnered with California based Kinsbursky Brothers Inc (also doing business as “Toxco” and “Retriev”) who were already active in related fields of recycling cellphone, laptop and other batteries. The creation of scrap in battery production as well as the need to dispose of defective, damaged or malfunctioning batteries from production vehicles made it necessary to establish a recycling channel from the start. According to Tesla’s blog, the Kinsbursky recycling method does not use metal smelting but is based on crushing and separating battery components into a copper / cobalt concentrate, plastics and slurry. The report, which is from the early days of utilizing the process, states that only 60% of the input materials are fully recycled while 10% are being reused in other applications; the rest goes into landfill. Since then, these ratios will no doubt have improved but exact information on current performance is not published by Tesla.

Tesla’s second partner, according to a press release, is Umicore of Hoboken, Belgium. The company took on an entirely different path of material recovery. In a first step, “large format” batteries are being disassembled at the company’s plant in Hanau, Germany, and segregated into “pack materials” (copper cables, steel, plastic), electronic components and battery modules. Most of the pack materials can be recycled or reused without complex processing. Efficient recycling process already existed in-house for electronic components. For the battery modules, Umicore inaugurated a pilot plant in 2012 employing a patented “UHT” (“ultra high temperature”) technology which, according to media statements, allows for an almost complete separation of metals and materials. The pyro-metallurgical process, which operates at or above 3,000° C, creates a metal alloy of cobalt, nickel and copper which is suited for further hydro-metallurgical separation afterwards. A slag fraction remains which, Umicore claims, is suitable for reuse in the construction industry, or for further refining. The company has since launched into an expansion of its plant with a goal to process much larger volumes of EV batteries in future.

Either technology will be facing cost/benefit questions concerning the energy put into the recycling of spent Tesla batteries. Unsurprisingly, a large number of startup companies are taking aim at this emerging market which analysts are predicting will be worth as much as US$ 20 billion by 2025 and beyond. Fueled by an enthusiastic supply of grants and venture capital money, the race is on for more sustainable technologies to separate battery materials.

In an interview with “The Guardian”, and in context of the creation of Tesla’s “Gigafactory”, Khobi Brooklyn, a Tesla representative, hinted at plans to “conduct onsite recycling of lithium ion batteries at the Gigafactory, capturing nickel, aluminum and lithium for use in new battery cells”. He was supported by Phil Hermann, chief energy engineer at Panasonic Eco Solutions, who said he expects to “ultimately see recycling rates at close to 100% for lithium-ion batteries”. Redwood Materials, a recent acquisition linked to two Tesla executives, might be a further hint in this direction.

Will an established entity pave the way to sustainable battery recovery? Or will a complete unknown, much like Tesla itself, succeed with an unconventional approach? It’s an exciting development which we will follow closely in this series.
