Battery based electric vehicles of today and tomorrow.

Everything is fuel injected. What is this talk about jetting changes.

Fuel injection is not a magic panacea. The ECU controlling fuel injection has to know to enrich the mixture when ethanol is present. First FFV implementations used a sensor in the fuel line. Eventually learned to detect bad running and guess more fuel was needed. Few E10 engines will run with more than 40% ethanol.

Additionally the fuel injection hardware has to be ethanol-resistant. Early fuel injection was not self-adapting nor ethanol tolerant.

Water settling out is not a high tech nor difficult problem to address.

Water does not "settle out" in E10 or E85, that is the problem. You are making my point that diluting gasoline with ethanol requires extraordinary measures, vs electric which effortlessly utilizes coal, oil, nuclear, wind, solar, hydro, whatever.

Not that I can see any sense to grow corn to fuel vehicles . Algae and such grown on waste land or ponds to manufacture synthetic fuel is an interesting scientific curiosity .

Again, they are not making the very precise specific fuel the engine was designed or EPA certified to use.

I asked the UPS driver the other day if they had any electric delivery vans yet. He said he heard that had some or they were on order but they semis that ran on natural gas. The link below states how they are using CNG.

UPS To Add More Than 6, Vehicles To Its Natural Gas Fleet

1 reasons why CNG is the new diesel | Fleet Europe

In 1979 UPS had an EV brown truck running routes in Huntsville AL out of the JEEC at UAH. It went "click click click" when driven because it used arrays of contactors to control motor speed before good inexpensive solid state motor controllers were available.

The issue discussed is whether hydraulic energy storage is a myth, a fable. The Helms plant illustrates that the concept is real, and apparently economically rational, its not a fable as asserted in a recent post.

That website defines the peak output attainable, it doesn't say how long until it runs out of water. Write them and ask them how long the water can produce 1200 mw.

1200Mw for how long ? At what cost to build the project ? Cost of to pump up the reservoir and the how much are the sales proceeds when the station is generating ? What is the time required to pump up ?
Where are the environmentalists going to allow the building of pumped storage ?

The hydrocarbon base stock from algae ponds would be refined to a defined end product . No different that a conventional crude oil refinery takes various base stocks of crude oil and end up with the same distinct product .

Using power in off peak hours would even out the changes required from the generating stations.

As for charging batteries it seems to work for myself and probably most of the people in this country including yourself. What does one of the main backup systems you have at work run on constantly? It would not be a battery System would it?

Install methane generators at the end of sanitary sewers. Might even produce a viable end byproduct.

I don't know the details but many large municipal dumps have plumbing to collect methane gas. Anyone know how this gas is then used?

You can Google 'Helms Pumped Storage Facility'. I'll summarize a few articles I found. First, this was built to complement Diablo Canyon Nuclear Plant, to absorb excess capacity at night then provide energy for peak system load later, typically late afternoon air conditioning. (A nuclear plant is pretty much constant output). It's a big buffer. A battery, if you will!

In terms of capacity it could power a city of 900,000 (SF for example) for two days. However it wouldn't be used that way because it is for peak-leveling.

Your cost and time questions are answered by the fact this has run 30+ years as part of PGE's grid. It's only about a third of PGE's total pumped storage capacity so they seem to find this method effective. PGE is a stockholder-owned corporation so apparently operation is economically rational.

In summary this shows that pumped storage is not a fable.

Your turn, if you have evidence for a fable I would like to see it.

Do tell us how many naturally occurring locations there are to store water at height or air under pressure ? How many are built without a tax break or a research grant ?

No its your turn. Show us how pumped storage is only a tale as you asserted, a fable.
