Default hypothetical - 12 kW and $20,000

If i gave you a black box, $20,000 and only 1 year to build it

black box:
Weight: 80 pounds
Dimensions:3'x2'x1'
that would supply a constant stream of AC or DC power 12 kWhr for 10 years



1. Can you build a car that would travel across the country self powered, carry 2 or more people, with a top speed of at least 75KM/h. and an unlimited range. and roughly how efficient would your car be. how much Hp at the wheel vs the original 12kWhr

2. Same as 1. but you have 25kWhr a 140 lb black box and you must have a top speed of 110 KM/H


you can build any type of car, it doesnt have to be built an electric car it can be anything(compressed air maybe)

Background

Let the reader understand, There are people today working on alternative power delivery systems (ie pap engine, blacklight power)

lets say this black box is a future technology that has been developed in 2011 . Most people are off the grid and power there houses with this black box, Exxon-Mobile stock is trading at 3$ a share. people in the 3rd world heat there houses and can cook there food on clean electricity not by burning dirty cow shit indoors.

What i want to know is what type of vehicle could we create that take advantage of this technology using the technology we have today.

in this case the black box's output is 12kWhr 80lbs hooking up 2 black boxes would give you 24kWhr.

With proper gearing speed is a no brainer. But your hypothetical power pack is unobtainium. Why bother with the hypothetical concept. I am assuming you want to be paid $20,000 if it were possible. Well maybe. Driving my SUV instead would cost me $24000 for 10 years. For hypothetical it is a moot point.

I'd take your hypothetical black box and grid tie it and over 10 years the 1,051,920 hypothetical kilowatt hours would produce a healthy profit. I'd then buy a 60kwh of high density Lithium cells for my car to get roughly 300 miles considering the income I'd get.

Hi Kyler

Give me your box - it would go in any one of a hundred electric cars,
12Kw continuous would keep the batteries charged
Effectively you would have 36Kw average during your 8 hour working day - that is enough for 100mph in most cars
In practice your battery pack would be able to give you Tesla performance and unlimited range
You would end up driving all day and still selling power to the grid while you slept!

Given the poor grammer in that quote I would wonder if it it were:
12kw over 10 years?
or
12kw per unit time over a 10 year life?
or
$20,000 out right and you get it in a year's time?
or
$20,000 per year cost?
or
$20,000 and you only get to have it for one year?
or
$20,000 payable by Western Union to a bank in Nigeria?

Is that 12 kw per hour for 10 years? That would equal = 1,036,800 kw hours for 10 years.

So for daily use that would be: 288 Kw hours

More than enough to power a few long range electric cars + power my very large all electric home daily.

Plus if you give me $20,000 to put it to use I'd be sitting pretty.

Hypothetically speaking of course.

Chances of me winning the power ball lottery twice in my life time with out ever buying a ticket are greater.

Default thinking outside the box

Thank you for your responses

Part II.


Let the reader understand, There are people today working on alternative power delivery systems (ie pap engine, blacklight power)

lets say this black box is a future technology that has been developed in 2011 . Most people are off the grid and power there houses with this black box, Exxon-Mobile stock is trading at 3$ a share. people in the 3rd world heat there houses, cook there food on clean electricity not by burning dirty cow shit indoors.

what i want to know is what type of vehicle could we create that take advantage of this technology using the technology we have today.

in this case the black box's output is 12kWhr 80lbs hooking up 2 black boxes would give you 24kWhr

Dude your in the wrong forum. This is for REAL electric cars you can build today. Nothing hypothetical. Blacklight power! HA HA HA HA. You must be jesting!

Hi Kyler

Such a "box" would be a world changer

Just a little thing please do a little homework and try to understand units, Kw/h is a nonsense unit

Energy/work is measured in Joules - this is a measure of the amount of work done. pushing 1 Newton (force) over 1 meter = 1 joule

A Watt is the RATE of doing work = 1 joule/sec

Horsepower is a RATE of doing work = 750 watts
Kw is a thousand watts

A measure we use is (strictly it is a non preferred unit) watt hours - this is the amount of energy delivered by 1 Watt over 1 hour = 1 x 60sec x 60min = 3,600 joules

A Kwhr is 3,600,000 Joules or 3.6 MegaJoules

Kwhrs are useful because most of us pay our electricity bills in Kwhrs
