In the magnetic resonance application is the emitting device always using power or can it "sense" a chargeable device and switch on? I guess from a environmental standpoint any "green" of an electric vehicle is gotta be right out the window if you've got devices constantly wasting energy - the idea of miles and miles of roads all wasting energy has got to be the stupidest idea I've ever heard.

I could see if there were few widely spaced special zones where a supercapacitor type device could receive a blast of energy but slow charging lithium ion batteries mile after mile via buried electronics would be insanely cost prohibitive.

If it takes a battery pack with a wired recharge time of forty minutes SIX HOURS to recharge wirelessly, why would I want to do wireless recharging of a car who's battery pack takes eight hours MINIMUM wired to charge?

I need my car Tuesday morning, not Thursday evening!

I always thought this was the smart way to go. Rebuild city infrastructure with roads that power and charge the vehicles running on them, and when they leave those heavy trafficked roads for smaller local ones they vehicle cites to run on its on battery supply. The idea that people could charge their vehicles largely for free would be a good incentive, and the powered roads would allow people to use their cars in a fashion we are all more accustomed too.

Of course, it sounds ungodly expensive, but we need to rebuild a lot of our infrastructure anyway. And that's a damn good way to spur manufacturing and construction jobs in this country.

I just wonder if, in the end, it would be better. Miles and miles of powered highways seem like they would use a lot of energy, even if we did line them with solar panels. It seems a good way to get off oil, but if we are just exchanging that headache to burn and mine more coal in oir own country...I mean, that's practically suicidal.

This theoretical development means that electric cars will surely succeed! After all, gasoline-engine cars didn't become popular until continuous no-stopping refueling became widespread.

Electric cars will catch on in a big way when denser power storage becomes economical, assuming the technology isn't supplanted by something else before that happens. That's the truth.

There's nothing that's a real engineering barrier to rapid recharging. The real problem is that existing affordable battery / capacity systems just don't have enough juice. Far more powerful (power-to-weight, too) ones have been developed and continue to be developed, but they're still much too expensive.

That's it.

Yep, or a reflection on the intelligence of the factory of people he employed to work on concepts. Or what kind of drive it takes to get new concepts out the door. Now I'm going to go back to my shop to majorly influence the technology and lifestyles of the 21st century. If he could do it, anyone can!

We're closer than we think.

Thanks to the creeping effect of mass communication, even those who have no plans to use an electric car are already becoming accustomed to them.

The garage where I work already has parking spaces with chargers. Your commute is unlikely to use the entire charge, so an 8 hour workday is plenty to get it topped up again for the drive back home.

Shopping centers are getting them too.

It's already happening, all around us.

Actually, a lot of places have had chargers for years and are taking them out because they were never used.

Ah, so that's why municipalities all over the country have been letting potholes grow until they're the size of bathtubs. That'll spare us the trouble of digging holes when we need to bury a million-dollar superconducting gizmo every fifty feet!

Don't get me wrong. I'm perfectly fine with scientists and engineers dreaming up a thousand cars we'll never use for every one we do. But it's going to take a lot more 50-year bridges collapsing in their 80th year of service before America starts taking infrastructure seriously again, and then we're going to be spending a few decades just trying to catch up.

RandomAxe: After all, gasoline-engine cars didn't become popular until continuous no-stopping refueling became widespread.

It takes less than five minutes to extend the range of a gas-engine car by hundreds of miles by refilling its fuel tanks. If electric cars could do the same thing, there wouldn't be any need for on-the-go recharging systems like this one.

That being said, this idea isn't going to take off. No municipality is going to dig up any of its roads and install subterranean chargers (at a cost of HOW MUCH per mile?) for the benefit of the small minority of resident taxpayers who own all-electric cars that can take advantage of them.

studebaker hoch: It's already happening, all around us.

All around you, maybe. I live in an area where you can get almost $12k in rebates and tax credits if you buy a Chevy Volt -- and the power company will install a high-speed charging station for free at either your home or your place of work. Since the Volt came out, I've seen . . . two of them.

I'd buy one, but I still can't afford one even with those incentives. In any case, the market share of electric cars is not currently at its highest point so far. It's power density and cost that will make the difference.

Electric cars could currently be built to do that, yes, by a number of different means. As I said, it would be too expensive. But I agree with your point -- elaborate, expensive, complex on-the-go charging systems are a difficult way of solving the wrong problem.

I think this is probably right, but because I think it's a bad solution. They said municipalities would never dig up their cobblestones to install incredibly expensive paved roads for the minority of taxpayers who owned automobiles, and they said we'd never have more major interstate highways like the Lincoln Highway. Things change.

All-electric cars are a great idea. The technology just isn't quite ready yet. Maybe soon, and maybe not. The on-the-go charging road is an interesting concept but a lousy proposal.

1) Make an electric vehicle with a removable battery.
2) Convert gas stations into battery changing stations.
3) Make it a federal crime to fark with batteries without a permit.

The Volt is a loser car. Around here, the Leaf is available. I see them all the time. I saw three in one day once, and usually see at least one a day.

Pretty much what I was thinking. Pull up to a recharging station, swap out your low battery for a fully charged one (for a small fee of course), be on your way in five minutes. Plus you can smoke while you're doing it. Hell, you wouldn't even need employees except the maintenance guy. It would basically just be an automat.

Pretty much this.

It would probably be the best and cheapest solution.

Problems I can see are:

It would pretty much require a standardized battery design.

I have no idea how heavy/cumbersome the battery packs are.

Fizpez:

It doesn't actually have to. This technology is a slightly slicker version of the transformers on power poles used to convert high transmission voltages to the low voltages used in your house... If you turn off everything in your house then you're not drawing a load through the transformer.

There is actually *some* waste even if you're not drawing power, but it's a lot less than you'd think. Less than one percent for a modern transformer.

Having said that, a power transformer is a sealed and optimized thing, and this system is not. Get bigger tires? Lose efficiency. A zillion detail things like that.

But slick as this system is, it's unnecessary.

Guidette Frankentits:

1) Make an electric vehicle with a removable battery.
2) Convert gas stations into battery changing stations.
3) Make it a federal crime to fark with batteries without a permit.


Given the variations in battery life from laptop batteries of the same marque, I can see lawsuits from people stuck in the middle of nowhere who traded for a battery.

There is an incredible amount of infrastructure for plugging things in. Any business has 3-phase. Any place you can set up a parking meter you can set up a charging station.

There's this assumption many people make that they have to have a vehicle that can go 400 miles every time... Which is valid if you don't have a gas station at your home, in the parking garage at work, at the motel you stay at after driving 200 miles, etcetera. Electrically speaking, one could have a gas station in all of those places.

If you're equating your have to go a week between *going to your farking home or place of work* the way you go to the gas station once a week, then yeah, electric cars are going to look stupid.
 
2011-10-30 08:27:43 PM
The price of building and installing all that would negate any efforts to suppress the technology. I like the idea of electric cars, but they aren't there yet.

Great idea, Miss Frankentits. Why haven't you started a company that does exactly this? You'd be a billionaire when it catches on. Oh, too much risk you say? Well no shiat. Idealism, meet reality.
 
2011-10-30 08:32:30 PM
Ok, I completely caught sayof that last bit...

If properly implemented, if you have an electric car, you have a gas station at home, at work, at the motel you drove a long way to reach, at the mall.

We're used to going to the gas station once a week. We're not used to the concept of fueling up at home or work.

And the system of trucks and pipelines for gasoline isn't exactly the most efficient thing ever.

If there's no vehicle, you won't be wasting energy from a load perspective, but there's always losses in the devices themselves, even with no load at all.

And with a load, you're still losing energy to just parasitic losses. You might get it 90% efficient.
