Electric Cars charging while you drive

**outsidelinebacker20** · 15-10-09, 06:17 AM

The magnetic field would cause all sorts of headaches for machinery, and I am not sure how good it would be for people. Biggest problem I see is that it is wasteful and not cost effective. You would have to figure out how to only turn it on when cars are present. The magnetic field requires power, unlike the cables that are suspended over trains. The current would have to flow all the time. Ya know, like they tell you to unplug your DC power supplies when you are not using the device. The vampire analogy. If a transformer is powered and hot, it is using electricity.

Connectionless charging's very inefficient. I don't see it happening any time soon. I get headaches when standing under high tension power lines. I couldn't imagine having to put up with that everywhere I drove.

i say just have a li-ion battery charger connected to the tires and while its rolling down the street it charges it

like a bicycle generator type thing

I think electric cars are an over-hyped design and just as wasteful in general. All this stuff sounds like it would only work in areas where roads can be kept nice and away from winter. Michigans roads are torn to crap, itd be a huge rebuilding effort here to do this, not to mention the required upkeep. I cant imagine these things would work in pot-hole ridden streets. Plus youd have to be able to afford to buy an electric car compatible with this. If you live in a rural area or drive a large truck for business purposes your still stuck.

I personally think Bio-Diesel is the easiest sell to the public and best next step option. Corn or whatever product you use can always be re-grown, you can pretty much just pour in vegetable oil into any existing diesel engine and it will run, with small modifications to the fuel system it could run in any weather conditions, you can make it from used cooking oil from restraunts too so the sources for it dont have to be strictly from a farm. In europe theres diesel cars that get better MPG then any production electric car as well. Heck if you wanted you can make it at home in bulk with DIY kits available. Seems like itd be more "green" to re-new an existing platform then force a whole new one onto the public.

Tell me about it, I couldn't imagine the headache this would cause if every road everywhere had this. And as far as efficiency they claim it has a 90% effeciency with this new technology which ain't half bad.

Yah plus batteries are like 5k to replace. That's why I don't buy a prius or something, maintenance long term would be expensive. I think your right, electric is over hyped (at least with current technology) and we need to fix up our streets before we can even think about turning them into batterie chargers. I'm sick of potholes.

Have you ever read David Blume's "Achohol Can Be A Gas"? Has instructions on making your own still, and how to mod your car and everything. When I recently moved up to Santa Cruz I found out this guy lives right down the street from me, and a lot of places here have bio-diesel fuel pumps (like our local U-Haul). I think although there's not currently enough corn to be sustainable for everyone to us eit, it seems to be the most efficient and readly available form of renewable and sustainable energy.

this aint anything new back in 1914 this was tried it was found that the most efficient type of motor in a car is the internal combustion engine and it still holds true today

Actually, if I recall correctly, the combustion engine was the most efficient, and using alchohol to power them was the most efficient fuel, but the "Big Oil" of the day had this nasty stuff they got as a biproduct of refining other petrolium based materials and needed to get rid of it. It was either they have to spend money to get rid of it, or they could sell it to everyone as a fuel since it was combustable.

Kinda like the making marijuana illegal so the hemp industry didn't take down the powerfull cotton industry. It's just how business works.

I don't think we need to replace the internal combustion engine, we just need to figure out how to fuel it better. And imo, I don't think electric engines are the answer. Hydrogen is a cool idea, but unless it can create it on the spot in the engine bay, it wouldn't work since having a hydrogen fuel cell would level a city block every time you get into a car accident lol.

I think it is a phenomenal idea, and one we should be doing now to move us out of this long slide into oblivion we are facing as a species.

Besides the simple fact that we need to upgrade our entire infrastructure in all aspects of our civilization, now!

We need the jobs, and we need the elbow room...and we need to start really feeding the technology industry if we want to have any hope of taking the next step that is needed.

First things first...

With some recent major breakthroughs in many different aspects of getting renewable energies... take a quick look at this awesome video..

<object width="560" height="340"><param name="movie" value="http://www.youtube.com/v/8tt7RG3UR4c&hl=en&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/8tt7RG3UR4c&hl=en&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="560" height="340"></embed></object>

Goodness watch that a few times, and think about how much energy that is ..and the potential applications for that alone.

And this is barely scratching the surface as to what we will wind up doing... This is still caveman stuff.

So with the simple and obvious direction we need to go in in terms of energy production (renewable!)... The most obvious and efficient energy we can derive from these means is ELECTRICITY!!!!

An Electric engine is hands down superior to an ICE (Internal Combustion/Compression Engine) is just about every single aspect you can name.

They are vastly more efficient - Diesels do attain high efficiencies as well however there is fuel, pollution and other drawbacks... Diesels are however a key part in the direction we should be going-- The entire roadway will not be done for a long while, and Diesel-Electric hybrids are a tried and true technology for today.

They are far more powerful... in a much smaller package.

They are faster.

Cheaper to manufacture.

Easier to fix...

There is the battery range/price issue, however that has come a long way in a short time. Currently the batteries can achieve mileage use that is sufficient for most peoples needs.

The price issue regarding the batteries has a fair amount to do with the supply/demand aspect... as the demand rises, and technologies improve as the demand open the floodgates, the cost will go down.

And again if the road itself is charging the vehicle as you drive the days of the future where you get in your car.. press auto pilot and drive cross country are so close I can almost taste it... At current electricity rates and efficiencies of electric engines.. a trip from LA to NY would cost far far less then a plane ticket, train, or normal gas car does today.

As far as the magnetic field causing problems... er HOW??-- and do you really think that is something we cannot address if there is? Put a little shielding in the cab.

Maglevs are pretty impressive and I have not heard of any health impacts regarding it either, as the field is localized.

I want to see this start ...now... and it is so I am kinda pumped about it.

Actually we have to phase it out eventually, might as well be sooner then later.

There really is no way to fuel it better as just about every thing we do in regards to doing it is a net loser.

Corn ethanol is a total net energy loser.. with a 0.8 to 1 EROI-

Can I give you a dollar for every .80 cents you give me and expect to get make a profit?

Hemp is a much better alternative, but even that is a 3 to 1 EROI - and still we have alot of other uses for hemp cellulose that are better suited to those industrial/food uses then it would be for fuel.

It is until we develop the ability to manipulate space to move us about...

Hydrogen is a pipe dream... and a net energy loser.

Certainly you have a point if we are using plasma induction inside the car to separate the O2 from the H and burning it from there.. which creates water--which keeps water in circulation--

However fuel cells are not the answer either because there is not enough platinum on earth to meet our needs...

Honestly we need to scrap the ICE- there are a lot of resources locked up in their body that could be put to better more efficient use.
