Tesla Could Use Up All The World's Laptop Batteries (18650's)

No :~
E=m*c^2 is for both, chemical and nuclear reactions.

Nuclear=bonding energy in nucleous
Chemical=bonding energy of electrons

Example:
H2+O2 mixture has a higher energy state than H2O when the bonds are reconfigured to the lower energy state of H2O this energy is released and hence mass.
But weight loss is only 0.294ng per gram of water produced-you can simplify, that there is no mass change :stuck_out_tongue:

so why does my nimh batteries deliver less output then my li ion? the lithium weighs less as well

premium Ultrafires.

Fusion and fission are the most common forms of matter to energy conversion. Neither, however, are REQUIRED. Radioactive decay is a perfect example. The interior of the earth is primarily heated by the decay heat of radioactive isotopes. Neither fission or fusion contribute to this conversion. The three damaged reactors in Fukushima, Japan as well as the spent fuel pools must also be continually cooled because of the Matter to Energy conversion of radioactive decay. No Fusion or Fission is taking place (well, at least that's what Japan tells us - I have other beliefs, but that's for another discussion)..

radioactive decay=fission
In nuclear physics and nuclear chemistry, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts…

Good news ! The technology in energy and batteries are so archaic it desperately need huge scientific research, the thing that is blocking the evolution is the oil based economic system.

Thanks for quoting wikipedia. Bill Nye the Science Guy, for the record, is equally frowned upon for quotes when talking about things more interesting and complicated than why solid water generally floats on liquid water.

fission is defined as the splitting of an atom into two smaller atoms. Uranium 235, for instance, after being struck by a free neutron commonly fissions into xenon and strontium. It can fission into many different things, but xenon and strontium are some of the most common.

Decay, on the other hand, does not create two atoms. A single atom releases a Beta or Alpha particle, and sometimes one or more gamma photons. It remains a single atom, but changes to a different isotope or a completely different element. Iodine-131, for instance, typically decays by emitting a Beta particle and a gamma photon to become Xenon-131.

Alpha decay-ejecting hellium nucleus. You get two atoms :wink:

85000÷7000=12.1Wh
I guess this is in small discharge current situation, just normal cells…

Just curious why Tesla would use 18650’s instead of custom li-polymer packs.

Don’t they have a higher discharge/charge rate and could be shaped into whatever rectangular solid?

Seems like they also would have higher energy densities because 18650’s form gaps when grouped into a box.

Not sure how it works, but the Nissan Leaf has a fast charger built in. In 15 minutes, it charges to 80% of the batteries.. I thought that was fast..

Sorry Bort, but —-

According to information on Wikipedia, a gallon of gas weighs 6.073 US pounds.
20 gallons of gasoline weighs 121.46 pounds US. (assume 15mpg)

Each electron has weight (very little, = 7.93×10−36 lb ) but some weight.
Electrons move down copper wires (Very little) but it’s a pretty good theory they move.
(Someone guy did the math on this in Tesla’s blog, can’t find it now, but until proven wrong, I’ll agree with him)

Come to think of it, maybe this explains how the new battery test works:

Lol
Us pounds, gallons and electrons walking inside a battery, and this video to proof it…. :bigsmile: :party: :bigsmile:

Borts mistake was that he used the standard unit for density but not standard unit for mass. I hope that sometime a scientist gets president of the US and that he forbids those weird units :wink:

54kg÷0.72kg/l÷(300miles×1.61miles/km)=15.5l/10^2km

15 liter per 100km

Does Tesla seriously think sales will ever hit this, it’s a joke, same as a certain low volume UK sports car maker stock piling cars in the USA pre registered to get the government grants for export from the UK gov!!
I would seriously love a affordable clean electric car, but in the UK at least that would mean the gov would find some way of taxing the “fuel” you put into the car, same as with gas/petrol.

A few interesting articles I read a few days ago giving a different perspective about the infamous, Tesla.

Critic: Tesla HAD to Repay Its Dept of Energy Loan to Avoid Default

Tesla Motors Inc (TSLA) May Switch From Panasonic To Samsung For Batteries

http://pulse2.com/2013/08/31/tesla-motors-inc-tsla-may-switch-from-panasonic-to-samsung-for-batteries/

I suspect that they’ll shift to custom li-polymer packs. Unless… there’s a major uptick to 18650 cell production. If so, might be a good idea to start buying stock of those companies. Tesla is producing stellar cars and if they make great strides in infrastructure support (like restaurants and hotels providing compatible charging ports for parked cars), and a more affordable quality car model for the masses, this company is going to take off like a rocket and give a major boost to partner companies. That is, of course, if they can get their finances in order! :wink:

Successful Tesla batteries versus unsuccessful Fisker batteries.

Nice link big wood.
I like the euphorism about electric cars, we burn the coal to make steam, transform it to electricity, charge up a car and then we have a co2 friendly electric car which is super clean and nice :wink:

you are correct, i didn’t convert 120lb to kg before calculating, that’ll teach me to do calculations after 3 in the morning

it seems people are thinking electrons are energy rather then carry energy
