Teenager Invents Cheap Solar Panel From Human Hair

samzenpus posted about 5 years ago | from the 50-watt-shampoo dept.

Power 366

Renoise writes "Milan Karki, 18, who comes from a village in rural Nepal, believes he has found the solution to the developing world's energy needs. A solar panel made from human hair. The hair replaces silicon, a pricey component typically used in solar panels, and means the panels can be produced at a low cost for those with no access to power. The solar panel, which produces 9 volts (18 watts) of energy, costs around $38 US (£23) to make from raw materials. Gentlemen, start your beards. The future of hair farming is here!"

9V != 18W (1, Informative)

I don't think the original article suggests they are the same, although it does seem surprising if this thing can produce 2A.

I don't think the original article suggests they are the same, although it does seem surprising if this thing can produce 2A.

If it produces 9V, I would not be the least surprised if it puts out 2A across 4.5 Ohms resistance.

Re:9V != 18W (5, Informative)

Eric Smith (4379) | about 5 years ago | (#29368273)

I would be quite surprised. If you buy a 9V alkaline battery at the drugstore, take it home, and put a 4.5 ohm resistor across it, you will NOT get 2A of current flowing through the resistor. The battery can supply 9V at a lower current, but with a load with too low a resistance, the battery voltage will drop.

The same principle applies to any other non-ideal voltage source. A solar panel that produces 9V open circuit or at some low current is not necessarily able to produce 9V at 2A.

If everyone wants to quibble over the little things, then i'm going to call bullshit on current flowing.

"Suppose that an amount of charge dq flows past some given point of the wire, in a time dt; then the electric current is defined as charge divided by the time..."

jimmyswimmy (749153) | about 5 years ago | (#29368295)

You should be surprised to get 2A out of this cell at any voltage! First, Ohm's Law doesn't dictate that a supply voltage be stable while current is being drawn. The internal resistance of the hair cell or whatever this [very unlikely] thing is will not be zero, therefore the output voltage will not remain a perfect 8.98 V as you load it. I have a hard time believing that a hair solar cell could exist (and the article did not convince me and should not convince you). I have a much harder time believing that such a thing could start up one of those CFL lights he is holding there.

The conductivity of hair is very low. I know this because I have inadvertently applied 600 V between 3/4" of hair and my (thankfully dry and unsweaty) skull, yet I live to type about it. The possibility of a hair solar cell is, in my oh-so-humble opinion, exceedingly unlikely.

However, I was [for once] inspired to RTFA.

Archon-X (264195) | about 5 years ago | (#29368205)

The 'active ingredient' is the melanin in hair. The catch is, this degrades over the period of a few months, not a few years. This is the reason why the price can be so low - there's a hidden 'cost' in lifespan.

Re:9V != 18W (2, Informative)

ajs (35943) | about 5 years ago | (#29368427)

From TFA:

Half a kilo of hair can be bought for only 16p in Nepal and lasts a few months, whereas a pack of batteries would cost 50p and last a few nights.

So, no it's not a hidden cost, it's just cheaper than the existing costs.

Re:9V != 18W (1)

alexborges (313924) | about 5 years ago | (#29368889)

Then again, hair can be produced simply by the act of breathing, even every two months....

Thats the idea I like about this: it gives independence to rural villages that could never pay for the infrastructure to get electricity to them.

Re:9V != 18W (4, Informative)

RegularFry (137639) | about 5 years ago | (#29368239)

Not sure how you've worked that out. At a fairly optimistic 10% efficiency, I reckon he would need about a fifth of a square meter to output 18W, given that sunlight has an energy density of 1kW/m^2, give or take. That roughly matches area of the device he's shown holding. A 30ftx2ft similar panel would have roughly 600W output.

This doesn't mean it's not bullshit, naturally; it just means that the numbers *could* add up.

Re:9V != 18W (2, Insightful)

John Hasler (414242) | about 5 years ago | (#29368257)

It is barely possible that he kluged up something that puts out 9 volts into the extremely high impedence of a digital voltmeter. The rest is bullshit, perhaps originated by the same doofus who thinks that a watt is a unit of energy.

gtbritishskull (1435843) | about 5 years ago | (#29368767)

I am confused about your point. Energy is just power * time. So, if he runs this thing for an hour (assuming it actually does what the article says it does, which is a huge assumption) then he will have 18watt-hour of energy (or 64.8 kJoule). Are you saying that you think it will burn up in an hour, because supposedly it can last a week or so.

Voltage is electromotive potential. It measures a sort of pressure that occurs on electric charge. Current is measured in amps and measures the flow of charge itself. You can't have power (watts) without current. So, no, voltage is not the same as power.

How strange, then, that the same 120V house circuit can power both a 25W CFL light bulb and a 1600W hair dryer (for example).

Electrical power does require a voltage source, but volts and watts measure fundamentally different thigns, and they do not correspond in the way the summary implies (unless you hold certain other quantities constant).

Re:9V != 18W (1, Informative)

It's an incomplete story. What we need to know to evaluate cost is A. life expectancy, and B. W/m^2.

This is really ridiculous.

The pictures show a few strands of hair. A few questions come to mind:

(1) Hair is not conductive. How can hair produce electricity if it can't conduct electrons worth a darn?

(2) Hair is not polarized-- it's the same all the way through and throughout its length. How can there be any potential difference set up across something uniform?

(3) The amount of hair shown captures maybe 0.1 cm^2 of sunlight. Even if it had 100% efficiency, that would only be 1/100th of one watt. How could it be lighting up a 5-watt fluorescent lamp with that?

Everything about this story sounds major-league bogus.

Hair is replacing silicon. Since silicon is a semi-conductor, I would not expect hair to be used as a conductor, but rather a semi-conductor. As another poster already pointed out, melanin is a decent semi-conductor:

From the sounds of it, the PV material is still normal, just using hair to replace an expensive part of the panel.

I'd have just gone with: if daily mail, no. This is the paper that is (unknown to them, apparently) the British cousin of The Onion [theonion.com] - despite Private Eye [private-eye.co.uk] 's best efforts.

Since the real source is the Melanin can't we just use dark skinned people to generate power? India may have a nearly inexhaustable power supply. Just imagine in this country, we could hook up George Hamilton. He's got to be able to power a city all on his own.

"NO WAR FOR HAIR"

"Obama appoints Hair Czar"

"Rupublicans push for offshore haircuts"

"The war in Nepal was all about securing their hair and had nothing to do with spreading democracy"

I'm very skeptical about this. Currently, lab developed polymer solar cells have about a 5% energy conversion efficiency. Let's assume that this kid made a solar cell that is twice that efficient, so 10%.

Let's say sun irradiance is 1000 Watts/meter^2, which is also pretty high. And lets say the solar cell is a .1 meter^2. This would make the optimal wattage for his solar cell:

Irradiance * Size of Cell * Efficiency = Wattage
1000 W/m2*.1 m2 *.1 = 10 Watts

Even in superoptimal situations, there is no way his cell can be producing the 18 watts described in the article.

I AM SO SICK OF THIS SOLAR BULLSHIT (0, Troll)

killmenow (184444) | about 5 years ago | (#29368709)

Yes, I screamed that loudly. I am frustrated. No, that doesn't even begin to capture the emotion. For the last nearly ten years I've read repeatedly about this cheap new solar thingamajig and that new solar breakthrough and how any time REAL SOON NOW cheap mass solar power will be available to all. Yet here we are, all these fucking years later after one anouncement after another of this breakthru and that front which will eventually lead to cheap solar with NOTHING TO SHOW FOR IT.

And for crying out loud I WANT SOLAR POWER. But I'm sick to fucking death of hearing this bullshit news. So until I can install enough solar panels on my roof to reliably power my home with enough spare energy to handle spikes AFFORDABLY, it's all bullshit.

I confidently profess I will NOT SEE CHEAP SOLAR IN MY LIFETIME.

And I'd gladly be proven wrong.

But I won't.

Anonymous Coward | about 5 years ago | (#29368929)

Every time you see a new solar technology it always have some voltage rating, but never power (VA). It's the number of watts per square meter that matters. Voltage means nothing.

FOOLS!!! Hair powers the brain. (1)

Don't people realise that the purpose of hair is to generate the electrical power for the brain. Start harvesting hair and it means the doom of the human race.

This is why older people sometime loose their mental health - because of a loss of hair and/or pigment, leading to a deficiency of electrical brain power. This is why people with bald or shaved heads don't seem quite right.

This is why we fall asleep at night - degradation of solar-generated brain power.

This is why we have retained hair on our heads - New Scientist are fools for not realising this

Fools - start harvesting hair at your peril!!
