As I person who has a dozen patents, I need to remind you that patents expire. No patent is good for more than 20 years (17 years in US). They cannot be renewed. Once they expire, anyone can use the technology free of charge. If you don't use the patent, you lose money. A corporation probably wouldn't sit on a patent because they would lose a lot of money.

This isn't marry magdalen in a grilled cheese sandwich this is monopolizing a market, Which by US law is illegal. They are breaking the law, end of story.
try using google to look at the track records of these company's, then defend them.

This one happens to be true. There's a reason today's hybrids are using the problematic many-little-batteries-strung-together format. They are unable to legally use larger NIMH's.
I know, it's Wikipedia, but with lots of external references.
Patent encumbrance of large automotive NiMH batteries - Wikipedia, the free encyclopedia
The patents are due to expire soon, but advances in Li-Ion chemistries will make it largely irrelevant.

yes they end but not till 2015- between 2003 and then you'd be unable to find a single battery sold by chevron that could be used in an EV- several company's have tried suing them to try and purchase batteries but no luck-
Even the inventor Stanford R. Ovshinsky said in an interview
"I think we at ECD made a mistake of having a joint venture with an oil company, frankly speaking. And I think it's not a good idea to go into business with somebody whose strategies would put you out of business, rather than building the business."

Too true. This article details the demise of electric trains in the Bay Area.
Quote:
There was also another player in the demise of the Key System and other city railways nationwide: General Motors. Between 1936 and 1950 General Motors, along with Firestone and Standard Oil of California, bought out electric train systems in nearly 50 cities—including Los Angeles, New York, Detroit and St. Louis—through a holding company called National City Lines, and replaced those trains with buses.

I remember hearing something that drilling won't lower oil prices, we can't drill our way to energy independence, it will take 10 years to bring the oil to market.
Well the other day I checked oil prices and they were $47 per barrel and the United States is an oil exporter for the first time in 75 years.
Oh and we reduced our plant food emissions in 2016 and 2017.
27 states have stations under $2 a gallon.
Good thing no one listened to the nay sayers.

For instance, a gen 2 prius has 168 6.5 Ah cells in a series making 201.6V. That's a 1.3kwh pack. It can pull about 28kw from that pack. That's 139A (peak, though).
Now say you have 65Ah large format NiMH readily available (10x the capacity in one cell!), so you put in 1.5kwh of those for the same weight and volume (it's slightly larger since you don't have as much packaging/interconnect). Now you have a 19 cell, 22.8V traction pack. That pack is going to have to deliver over 1200A peak. Those conductors will be huge, that motor is going to be huge, and all that mass of copper is going to cost $$$. A low voltage pack is only economical for mild hybrids. IIRC Hyundai sold one for a couple years in Europe with a 48v pack, but it could just supply a bit of motor assist and stop/start functionality.

See wikipedia.org:General_Motors_streetcar_conspiracy
Not just there. oregonencyclopedia.org:Oregon Electric Railway
Quote:
The Oregon Electric’s 122-mile Willamette Valley route was Oregon’s longest electric interurban railway, and many of its trains served Portland suburbs. A dozen trains a day catered to commuters, students, and shoppers in Hillsboro, Forest Grove, Beaverton, Wilsonville, and Tualatin. On weekends, reduced-fare excursions operated between Portland and Salem. Four to five trains ran through to Eugene each day.
|
Somewhere I have a copy of Oregon Times that tells the story. The Oregon Eelctric line was operating in the black when a consortium bought it and stacked up and burnt the rolling stock.
Quote:
To compete with major steam railroads, the Oregon Electric ordered the highest quality interurban cars available.... Rolling stock included combination baggage, smoking, and passenger motorcars; observation-buffet cars; and elegant passenger trailers. For a few years, there were also specially built interurban sleeping cars.

You may remember back to October,1973,when West Texas intermediate crude was selling for $2.90 a barrel at the wellhead,and Saudi crude was selling for 25-cents a barrel.
For many decades, thanks to OPEC,the selling price has had absolutely nothing to do with the cost of production,plus a reasonable margin of profit.
And with corporate taxes down now,businesses can afford to lower prices and make the same profit margin.
