Thread: Battery powered? maybe not

Battery powered? maybe not
I was driving along the other day and passed a Prius and thought are batteries really the way to go? It seems they have to be replaced after 4-5 years at cost of around 5000. they might be green but a bit expensive, surely there must be a better way.Ok they will no doubt get better but at the end of the day, batteries are batteries.
I know several years ago when living in the UK a guy invented a steam powered car that could fire up in less than a minute and do 300 mpg on water. Maggie Thatcher promptly put a 35% tax on his water and it killed the idea stone dead over night.
Ok, I know theres vested interest pushing the barrow a certain way and this interest can be very intimidating. Pro Hart was before he became a painter, an engineer and maintained a workshop out the back of his home. He came up with a working model of a magnetic motor. But he started to get odd visitors in suits who were more interested in his workshop than his paintings. Which prompted him to dis-assemble it as did not care for their manner and attitude.
Over the years I have read up on all sorts of ideas for free energy, over unity, etc etc, played around with some with mixed results to out right failure. One wonders if there is not some grain of truth in one or many of such ideas and patents.
I am reluctant to dismiss them all as crack pots and lunatics for the following reason. My Grandmother was born late 19th century and was old enough to see/hear of the Wright Bros heavier than air flying machine successes and lived long enough to see a man land on the moon. Now at the time of the first flight, many believed such a thing could never happen. The idea of flying to the moon in 1903 or so, would have been considered preposterous... crackpots and lunaticsagain
So I wonder what is possible and is it around today some where already? What of some of Tesla's patents and ideas or perhaps Viktor Schauberger.Inspiration exists, but it has to find you working. — Pablo Picasso

Im on my third Prius and they get incrementally better each time and the first one was great. There is just too much sensible engineering for me to ignore them.

Electric motorbikes averaged 96.8 mph around the Isle of Man this year, with a top speed of 141mph.

Check out the Hydrogen powered cars in California. I watched a special about them on tele some time ago and was very impressed.

I read the above a few times and am still confused. Ok, the 300mpg refers to the fuel burned to produce the steam obviously, but a 35% tax on his water!
I was visiting the UK at this time - was there 5 years - and can't remember the great stink which would have resulted from a massive increase in the cost of water.
Then the idea that M Thatcher picked on one prototype and ruined a complete research and development program is hard to accept even from her. After all he wasn't even in a union.
Could we have some clarification please Hughie?
Cheers,
Jim

There was an Australian steam powered car- the GVang - that had great potential but from memory some thugs broke into the workshop and smashed the thing to pieces.
As for battery power, I am still sceptical, as i am with hybrid cars. Hybrid cars have about 50% more moving parts than an "ordinary" car. Yo me more parts=more problems.
Some of the current high output small engined cars are producing consumption figures close to those of the Prius. Why would you go hybrid when this is the case??

Ive never had any mechanical problem with my Priui (the plural of Prius?). They have been unfailingly reliable.

Ahh EV's now theres a subject i love.
First off let me say the ONLY problem holding EV's back at this stage - from a technical stand point not a political stant point - is battery capacity & recharge rate - & while ICE's (internal combustion engine) have been around for well over 100 years with billions of $$$ spent over that time to improve ICE's, (most scientists now believe that we have squeezed about all we can out of an ICE) the humble old battery has had very little in the way of real R & D over this same time - after all for most of the last 100++ years all we have needed from a battery is to power kids toys etc. Its only in the last decade that any real improvements have been made to battery technology & most of those improvements have been driven by mobile phones & laptops - hardly a high capacity/discharge requirement compared to an EV!
Your first statement is very true Artme, which is why i'm not keen on today's style of hybrid (these are known as 'parallel' hybrids). You have 2 motors, one petrol & 1 electric & both need to have the capacity to move the car thru its full range of speed & both need to be interconnected therefore as you have said - more moving parts which mean more things to break down.
IMO a much better option that would also help to push the development of better batteries is what is known as series hybrids. This is where you have just 1 motor doing the moving of the car while a second ICE (diesel) is dedicated to charging of the onboard batteries. There are a number of huge advantages to this type of car, first off the electric motor is doing all the work of moving the car ( at an efficiency of around 80%++ rather than around 25% for an ICE) which means HEAPS few moving parts than an ICE (electric motors only have a couple of moving parts) Secondly the ICE doing the actual charging can be designed to run at the most economical RPM without the need for the huge torque curve needed by a typical ICE to move a car. Another bonus to this type of 'hybrid' is that the ICE charger can be mounted to a very small trailer that can be hooked up at a moments notice when a little more range is needed (most Australians if they actually sat down & looked at their weekly motoring usage will find that over 90% of their driving wouldn't even require a charge assist trailer) These types of small charging trailers are already available & are only around 500mm deep & have what i think is called positive tracking - this means there is no issues with jack-knifing the trailer while reversing.
As for why buy a hybrid vehicle, well you can bet there were plenty of people who said the very same thing when the first cars were produced - after all the very early motor cars were far less reliable, more difficult to keep on the road & much more expensive to produce than any horse!
Its completely clear to me that EV's are the future private transport - there are just a few issues that need to be improved before they are accepted by the general public. The more people who show interest in EV's, the more people who buy hybrids & more importantly pure EV's then the more that will be spent on researching better battery technology. At the moment petrol is still too cheap for most people to do little more than laugh at the idea of EV's - give it another 10 years or even just 5 & i have no doubt we all will be looking back at the old stinky polluting ICE & wondering why the hell we didn't wake up years ago. Who of us could afford to pay $ 3 or 4 per liter - or worse!
1 other point that i would also like to raise is the fact that todays generation of Lithium based batties for EV's are over 85% recyclable. Recycability is an issue that is very high on the priorities of those designing new battery technology.
I could go on writing about this subject till my fingers are sore & you are all bored stupid reading so i'll end it here.
But to all those who are still down on the whole idea of an EV please think again, look at your actual driving needs, look at the real $ savings to be had from an EV - not the rubbish propaganda that is pushed those with a vested interest to see the EV remain buried for as long as possible. With todays fuel prices & todays battery prices EV's are already in-front albeit only marginally, if you then add in the concept of domestic solar power generation & the whole EV idea gets even better (thats not even taking into account the saving to be had from real large scale mass production of batteries). Its going to take some changes on the way we drive, the way we produce power, the very way we live our lives to make a petrol free future a reality but its a reality i'm sure we can all see coming weather we like it or not. Realistically the change won't be much harder than a horse driven economy to a oil driven economy. The main difficulty is the almost insurmountable power of the oil companies & those who feed from that poisonous pie.

The ideal vehicle that rattrap seems to describe already exists in the form of diesel-electric locomotives. And the current crop has fully regenerative braking. Not free energy, but less wasteful because it's recycled. Diesel was originally developed to run on vegetable oil, so it could be less dependent on petroleum.
Petroleum is still needed for feedstock in plastics, and also for asphalt paving (generally from the bottom of the fractionating process).
We seem to be seeking a single magic bullet that will solve all of our energy and environmental problems. What's really needed is a more enlightened allocation of sources and sinks. Wind, where available; solar, where available; ditto for geothermal, ocean thermal energy conversion, hydro, coal, natural gas, and God knows what else.
Portable fuel for automobiles was originally bought by the bottle at chemists. It took many years to develop the present infrastructure. With the benefit of hindsight, the new infrastructure can be developed more rapidly, if the bickering can be reduced.

I gather the heat source was kerosene and with additives to the water the start up time was tolerable ie less than a minute. The water was for the most part condensed to be reused. But not entirely hence the 300mpg figure being touted at the time in the papers.Inspiration exists, but it has to find you working. — Pablo Picasso

Sorry Hughie. I'm still not sure what this increased tax on water was that only affected the viability of one prototype and not the rest of Britain, not the cooling towers of the power stations, not commercial or domestic users etc.

So the 300mpg refers to 300miles per gallon of water? The way it was first mentioned the implication was that you were talking about 300miles per gallons of FUEL burned. Two totally different things. Are you sure it's not 300miles per hour???
If the heat source was kerosene I don't see why Thatcher was worried about it being a threat to North Sea oil...kerosene is a petroleum product isn't it?Whatever note you blow youre never more than a semitone away from the correct one....(Miles Davis)
