Not seeing where you are getting that statistic, but I doubt depreciation is factored in.

Why the smart money is on Duncan Hunter

In this poll Hunter is up 3% and even with Paul and Thompson.

I thought I was quoting your number, you may have been quoting someone else, but $.7 per KWH is 70 cents to me.
I pay 10 cents per KWH where I live. 70 cents for natural gas generated power seemed a little high, It must include depreciation because I can generate electricity for about that cost with a gasoline powered generator.
Ah....That was a typo on my part. I was referring to the 4.7 Kw (max) electrical output of the unit, as being a “fair” amount of electricity to run things with, during a blackout.
Fair, as in, it’ll keep the fridge , TV, a couple of lights and a fan ruuning...but it won’t tun all of a family houses’ appliances, and certainly not a Central AC..not even with a window AC..if all the other stuff is on too.
Instead of typing ‘4.7’, I typed ‘$.7’
“I do wonder how long it would take to recharge the nano-li-ion Tesla with a range of 800 miles.”
It always comes down to time and money. If these nano-wire batteries cost a fortune, then it won’t matter that a 200lb battery can take you 800 miles. Or if they have to be charged slowly like tradional Li-Ion batteries, they are also a non-starter. I’d rather have a set of A123 or AltairNano batteries that can be recharged in 10 minutes, even if they do weigh 600lbs to go 200 miles.
An electric airplane, on the other hand, is a different story. Weight will be king in that application.
Toshiba to release fast charging battery
December 12, 2007
The company said its Super Charge ion Battery can recharge to 90 percent of full capacity in less than five minutes. Tokyo-based Toshiba (OTC: TOSBF) announced that it planned to release a fast charging lithium ion battery early next year for use in industrial vehicles and other applications.The company said its Super Charge ion Battery can recharge to 90 percent of full capacity in less than five minutes.
Toshiba said it plans to make the battery a mainstay of its industrial systems and automotive products businesses, with the first system to be shipped in March 2008.
"The excellent performance of the SCiB will assure its successful application in industrial systems and in the electronic vehicles markets as a new energy solution," said Toshiharu Watanabe, CEO of Toshiba's Industrial Systems group.
"In terms of environmental impacts, the SCiB offers a long life that will reduce waste."
The company said its battery management system monitors voltage and temperature in order to protect the cells and balances the state of charge in each cell.
Toshiba expects its batteries to be used in battery-powered bicycles, motorcycles, automated guided vehicles, electric forklift trucks and construction machinery.
The company also said the new system is a promising candidate for emergency power sources, electric power regeneration in wind power systems and stabilization of electric power supply, with applications in hybrid and electric cars also planned.
Heck, I have a girlfriend who swears she can recharge batteries by putting them in the microwave oven.
I’ve never tried it, as I like my Microwave, kitchen, house, and personal belongings.
Don’t feel bad. I’m still waiting for my ride on the Pan Am Clipper Shuttle to the Hilton Space Station. Should have been here over 6 years ago....still waiting.
This is also accomplished by altering the duty cycle of the charger. I have an R/C battery charger that uses this technology for charging NiCds and if they are cycled properly I've had them last for 15 years.
If this tech is for real, LiPo should be phased out.
The beauty of LiPo is their size and weight advantage. I'm seeing LiPo batteries showing up in the R/C world that are tiny, but give power similar to much larger NiMH and NiCD batteries.
Another thing to consider with NiCd's is the damaging heat may not come from charging. If you live in Phoenix or Yuma you may very well see a significantly shortened battery life just by virtue of being exposed to summer heat. It doesn't take that much heat to do serious harm to NiCads.
Have you heard of Europositron? They have a theoretical approach to developing a rechargable aluminum air battery. It also promises energy density similar to what nanofiber silicon lithium is promising.
I really want a normal sized vehicle with good performance and 500+ mile range that doesn’t run on imported fuel.
Yes, but it doesn’t have the energy density of the nanowire li-ion battery described here. A123 Systems already has its fast-recharge li-ion battery on the market — for a year now. But a battery pack that will run a small electric car for 200 miles weighs 600lbs — compared to about 50lbs of gasoline.
The combination of fast-recharge and high energy density would be great. The nanowire energy density comes close to gasoline. That would mean you don’t need to carry a huge weight around with you on the road or in the air.
