energy has no mass, energy and matter can be converted but a battery is not a nuclear reactor it stores energy chemically not by changing matter into energy, converting matter to energy requires fusion (like the sun) or fission
e=mc2 means if you had a chunk of matter and you could convert it all to energy you would get the number of joules specified by the equation.
And if you convert energy into matter, you would get the amount of matter indicated by rearranging the equation to solve for m
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
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)..
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.
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
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.

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!
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
