that the EVSE does not know what car is connected to it. For example, i mig ht allow a Tesla to discharge (feeding the grid) to 50%, but would not want a Leaf to do that. ChaDeMo can tell the EVSE what is connected to it, CCS or J1772 can't.

there wouldn't be any discharge.

g) but the fact that VW, Hyundai and others have already announced support in their cars indicates it is on the way. It doesn't require any hardware m odifications as a bidirectional datalink already exists in CCS.

All existing CCS vehicles does not allow bidirectional control. VW, Hyunda i and others would have to come up with a new protocol to enable it. Meanw hile, charging stations would not be providing it any time soon, since it c an't tell what vehicles are connected to it. In another word, CCS (at lea st the current version) is not possible for grid storage.

Death of ChaDeMo has been greatly exaggerated, said Mark.

Well, CCS 2 perhaps, and all new charging stations and vehicles.

I think they will add two more pins to the TCS (Triple Combo System). This away, it would not be compatible with existing CCS plugs, and give them mo re times to build their EVs and compete with existing EVs. In the future, there will be ChaDeMo, CCS and TCS for all fast chargers, until they drop C CS. In another word, CCS was a marketing plot (sorry plan) by some auto ma kers.

t converting electrical energy into hydrogen and converting it back to elec trical energy loses about 75% of the energy you started off with. Batteries only lose about 15%.

source is free. I think the idea is that the big solar installation alread y powering the grid will be a bit oversized to send power to the electrolys is process on the side.

d they have to have the dust washed off from time to time.

you invested to buy them in the first place, in the same way that the cost of hydroelectric power is essentially the interest on the money you had to spend to build the dam and the power station and the turbines and generati ng plant you put inside it.

not unlike nuclear, fuel is only a few millicent per kWh, buildind and fina ncing a plant it cost billions

Go to Thorium Molten Salt Reactors. We will never run out of fuel - it is everywhere, even on the moon. No expensive fuel processing is needed - thorium is used as it comes out of the ground. No expensive steel pressure vessel is needed - runs at atmospheric pressure. Self-shielding so minimal extra shielding is needed.

Cannot melt down - it is already molten. No auxilary storage needed - power expands and contracts with load. Walk-away safe. No need for spent fuel storage pits.

Extremely high fuel burn - approaches 100%. Can even burn radioactive waste from conventional reactors. Runs at much higher temperature than water-cooled reactors which increases output and efficiency.

No chance of a steam explosion - there is no water in the reactor. Three Mile, Chernobyl and Fukushima cannot happen.

Molten salt does not need large body of water for cooling. Sites can be close to point of use, so power lines are shorter and cheaper.

Molten salt reactor byproducts are easier to handle and can decay in 300 years instead of millenia from conventional reactors.

Current reactors get fuel burn of 0.5% (0.7% for Candu), then fuel rods must be removed from reactor. The spent fuel rods are highly reactive and need expensive storage pits to cool. Spent fuel requires expensive processing and long-term storage in salt mines. A multitude of hazards exist that must be protected against. These all increase cost for conventional reactors.

First examples ran around 1965, so we know it works. Development is slow with minimal funding in most countries. China is running full-tilt and could monopolize the market.

The best designs occur in the theta state. - sw

adds heat to their local district

Usually heats the air in the immediate vicinity, but there are schemes wher e you heat up the ground under your house all summer, and use the heat you dumped there during the winter to when your reverse cycle air conditioning can pull it out again. You don't have to go very deep to get a thermal time constant of about a year. It seems to be cheaper to go straight down, rath er than dig up a lot of dirt and put it back.

It seems more likely that will just continure to use homeplug greenphy over the existing pins.

Jasen.

All energy sources are free. Coal in the ground costs nothing. Ditto oil. Ditto gas. Ditto Uranium oxides.

Yet somehow we always end up paying for energy. Clearly, there's something wrong with the "free" notion.

True. They can also eliminate the pilot and proximity pins and run everyth ing over the power line. But that means all existing CCS vehicles won't wo rk. So, CCS days are numbered. Four more years until 2025.

Next gen chargers might only have two pins. Does it sound like Tesla? The original CCS idea was trying to make it KISS, now they have to make it as complicated as possible.

Unlikely. It will be expensive to separate the high-frequency signals used for PLC communication in CSS if it went over the power wires. Much easier t o send it over the pilot line as is done now. So you end up with the CCS2 c onnector as defined now. (Tesla has the same number of pins, 2 power, 1 gro und, 1 signaling).

All the other features are available with the existing connectors with soft ware changes, current cars may be compatible with updated software (or the features are backward compatible).

All that is required on the power side is a contactor to disconnect the bat tery from the power pins - that is on all cars today capable of fast chargi ng.

They're here already:

Why is hydrogen "incredibly pure" ? Makes no sense. All elements are pure.

That site is such blather.

Fuel cells have been promising since 1838. Hydrogen has been expensive for even longer.

Have you ordered a fuel-cell hydrogen car?

I don't drive even 750 miles annual, making it cheaper to use Uber than own a car, although I still do. It's rare to wait even 10 minutes for them to show up, they're swarming all over the place.

It is easy enough to do a back of the envelope calculation. Above a certain size a couple of H bombs do not do it.

Above a certain size an asteroid is lot easier to see, and we'll have to m ore time to deliver more impulse, and perhaps more impulses. The further aw ay from earth it is when we do it, the smaller the impulse required to get the asteroid into a orbit that doesn't involve it hitting the earth.

Clearly you are either using too small an envelope, or not thinking hard en ough about what would need to be achieved.
