ื”ื•ื ืงืจื•ื™ "ื™ื‘ืฉ-ืขื“",

ื•ื›ืฉืžื™ื™ืฉืžื™ื ืื•ืชื• ืขืœ ื›ืœ ื—ื•ืžืจ ืฉื”ื•ื,

ืžื” ื–ื” ืกื•ืคืจ-ื”ื™ื“ืจื•ืคื•ื‘ื™?

01:15
A windshield coating is going to give you about 110 degrees.

26
85488

ืื– ื›ื—ืœืง ืžื”ื”ื“ื’ืžื”,
01:27
what I have is a pair of gloves,

ื”ื‘ืืชื™ ื–ื•ื’ ื›ืคืคื•ืช,

ื‘ืฆื™ืคื•ื™ ื”ื ื ื•ื˜ื›ื ื•ืœื•ื’ื™,

ื ื™ื—ืฉืชื ืฉื–ื• ื”ื›ืคืคื” ื”ื™ื‘ืฉื”?

ืžื” ืฉืงื•ืจื” ื”ื•ื ืฉื›ืขืช ืื ื• ื™ื›ื•ืœื™ื

ื›ื“ื™ ืœื”ืคื™ืง ืžื”ื ื”ืจื‘ื” ืชื•ืขืœืช.

And we're talking really small here.

ื•ืžื“ื•ื‘ืจ ืขืœ ื“ื‘ืจื™ื ืžืžืฉ ืงื˜ื ื™ื.

The way you measure nanotechnology is in nanometers,

ื ื ื•ื˜ื›ื ื•ืœื•ื’ื™ื” ื ืžื“ื“ืช ื‘ื ื ื•ืžื˜ืจื™ื,

ื•ื ื ื•ืžื˜ืจ ื”ื•ื ืžื™ืœื™ืืจื“ื™ืช ื”ืžื˜ืจ,

and to put some scale to that,
40
128321
1647
ื•ื›ื“ื™ ืœืกื‘ืจ ืืช ื”ืื•ื–ืŸ,
02:09
if you had a nanoparticle that was one nanometer thick,

02:13
and you put it side by side, and you had 50,000 of them,
42
133274
2815
ื•ื”ื™ื™ืชื ืžื ื™ื—ื™ื 50,000 ื—ืœืงื™ืงื™ื ื›ืืœื” ื–ื” ืœืฆื“ ื–ื”,

ืื ื›ืŸ, ืงื˜ืŸ ืžืื“, ืื‘ืœ ืฉื™ืžื•ืฉื™ ืžืื“.

ื•ื–ื” ืขื•ื‘ื“ ืœื ืจืง ืขื ืžื™ื,

ื•ื’ื ื›ืžื” ืฉืžื ื™ื ืžื–ื•ืงืงื™ื.

ื ืขื‘ื•ืจ ืœื”ื“ื’ืžื” ื”ื‘ืื”.
02:45
we've taken a pane of glass and we've coated the outside of it,

we've framed it with the nanotechnology coating,

ืื– ืžื” ืžืชืจื—ืฉ ื›ืืŸ? ืžื” ืงื•ืจื”?

ื–ื” ื ืจืื” ืœื›ื ื—ืœืง, ืื‘ืœ ื–ื” ืœื.

ื•ืœื›ืกื•ืช ืืช ื”ืžืฉื˜ื— ื‘ืื•ื•ื™ืจ.

ื•ื”ืžื™ื ืคื•ื’ืขื™ื ื‘ืฉื›ื‘ืช ื”ืื•ื•ื™ืจ ื”ื–ื•,
