ORNL In-Motion Wireless Charging of Electric Vehicles

[dufremle]

Oak Ridge National Laboratory's Industry First experiments on in-motion wireless power transfer systems with pulsating power smoothing on the grid side with Li-ion capacitors and on the vehicle battery side with electrochemical double-layer carbon ultra-capacitors.

Cool, if it's at Oak Ridge, it's probably nuclear and they just keeping it a secret.

[DarcShadow]

interesting, lots of hurdles to over come and the pulsing is just small one. How long of a run of coils will be need to give a vehicle any sort of useful charge while driving 65 down the road? There will need to be a smart circuit so that the coils are not radiating power all the time, that'd be a huge waste. It's good though in that it doesn't require a constant cable run all along the road.

[BeautifulDisaster]

Very cool; a work in progress and worth it.

i don't see it

competing technologies like super capacitors are receiving more R&D and seam more realistic

[DarcShadow]

I wouldn't say it's competing, they could work together. The super capacitors are going to need to charge and having things like this on the freeways would mean they would have to charge that much less.

There's also the question on this thing of payment. They'd have to have a way to identify the vehicle and if it was authorized to receive charging. Then there's the question of what if two vehicle are over the charging area at the same time. Cause as I said before, the charging area is going to have to be pretty long in order to get a decent charge while doing 65. There will also be the question of what effect the EM field will have on other things and people. I'm sure some one will do a study and determin that it causes cancer.

super capacitor + charging tech = same distance and speed of a regular gas fill up, would make this obsolete

[DarcShadow]

Na, use this with the charging tech, might not need roads with it, but people are lazy, if they don't have to plug their car in when they get home they'd go for it. Just pull into the garage and the car starts charging.

"Son, you're a little strange, did you grow up under a power line?". "No sir, but we have two high capacity wireless quick-chargers in our garage, and my room is over the garage, does that count?".

I looked at a video where a kid made some type of water powered module that allowed him to get small engines to over 800 miles per gallon. He has plans to work on full size engines as soon as he has the money to buy one or has one donated.

[DarcShadow]

There is also tons of videos from the 80s I think of a guy that had an engine that ran on water and there even more videos about the conspearicy theory around is death.

[fixxervi6]

800 miles per gallon, break that out to KWh per mile...

That comes to 24 miles per KWh, no way in hell an ICE can come close to that, I would be SUPER impressed if the claim was 4 miles per KWh but 24, that's in the unicorn zone.

He built a hydrogen fuel cell. Nothing to see here.

[fixxervi6]

Hydrogen is an energy carrier not an energy source.

[dufremle]

The conversion of water to hydrogen creates electricity that is then stored in a battery. All this kid did was create a fuel cell that stores energy in a battery and add it to a gasoline engine, aka a hybrid.

He hasn't even tested it on a moving vehicle. One he does he will find out how big of a battery is needed to reduce the use of the gas engine.

For those who don't know, hydrogen fuel cell vehicles are battery powered hybrids where the fuel cell recharges the battery instead of a gasoline or diesel engine. The problem with hydrogen is that there is currently no infrastructure to refuel vehicles and each station is estimated to cost approx. $1,000,000 to build.

Toyota is planning on releasing its first HFC vehicle next year at an estimated cost of $70,000. It's going to be a while before they become affordable and you actually have a place to refuel.

[fixxervi6]

Backwards, it takes energy to get the HHO out of water and when you run it through a fuel cell you get H20 back.

All he is doing is creating HHO then burning it in a combustion engine.

You can do this with a 9 volt battery, a bowl, two test tubes, some water, salt, and two piece of wire. Maybe not as fast or as efficient as he is doing it but there is nothing magical about it.

[WillK675]

The Hydrogen thing has been done for years. The problem with it, and the reason it didn't and won't take off, is that it is still gasoline dependent. You have to start the engine on gasoline, use part of the energy produced to start the Hydrogen production, then you can switch to and run off Hydrogen. Then you have to run gasoline again, for a period of time prior to stopping the engine.

[dufremle]

I think there is some confusion here. Fuel Cell vehicles don't 'burn' hydrogen. There is no internal combustion engine. The hydrogen is mixed with oxygen in a chemical process that generates electricity. That electricity is used to charge the batteries that power the vehicle, think hybrid electric vehicle but charged by hydrogen conversion instead of an engine/generator combo. A by-product of the process is water.

Here is a short video of the FCV Toyota is supposed to release in a year or two:

Toyota is terrible and the prius is proof

[DemonDuck]

I am thinking whatever this kid made is different. Especially if he earned awards for it. It would seem that what he made is better and could work but I could be wrong.... it has happened before.

[DarcShadow]

I thought I was wrong once...but I was mistaken.

[LonestarCBR]

Damn, the stuff we have in common.
