Solar Cells — Made In a Pizza Oven
stylemessiah writes "The winner of several Eureka Science Awards in Australia is a crafty chick who devised a way to create solar cells cheaply using a pizza oven, nail polish and an inkjet printer. This was developed to address the high cost of cells and in particular for the world's poorest regions. She wanted to give the ~2 billion people around the world who don't have electricity the gift of light and cheap energy. This could have profound (and a good profound) implications for education and health in those in the poorest regions in the world. And it all started with her parents giving her a solar energy kit when she was 10..."
Last time I checked, they had already figured out how to produce low-cost solar cells. They're already shipping. The tech mentioned in the article may take 5 years to fully commercialize.
Heaven forbid anyone seek financial benefit for their innovations...
She wants to help the poor people of the world.
So, she found a process that uses cheap, easily accessible parts that would allow people in poor countries to help themselves.
And she patented it. So she can commercialize it.
Fuck off and die, bitch.
Just because you patent it that doesn't mean you have to charge an arm and a leg for it. Some people simply get a patent so others can't steal their idea. Say some gready corp who says hey this is cheap and effective and we can make a fortune even if we up the cost 5000% or more.
She's a PhD student -- she probably didn't have any choice in the matter, as the patent is probably held by the university.
That's perfectly fine, actually, just as long as you don't claim to be doing everything for the sake of the poorest people on the planet. That's a contradiction.
Those who advocate genocide deserve every protection afforded by law, and none afforded by common human decency.
Why use a lame term like that? Women are just as smart as men and when they do something brilliant they are recognized as something special because they happen to be a woman. So we have to do something like call them "Chick" to degrade them.... Well, that's how I feel anyway. Flame away! And yes, I'm male.
It's not so much the number of cells you'd need to power the oven, that's important. It's whether or not one oven load of cells could produce more energy over the entire lifetime of the cells than the energy it took to bake them.
I have no idea oft he numbers involved myself, but put like that, it doesn't seem nearly so ridiculous. Hell, the cells might still be worth making, even if you loose power on the deal; just think of them as very long life batteries.
Don't let THEM immanentize the Eschaton!
That's impressive. Though there seem to be scant details on efficiency and cost comparisons (I'm assuming this is more environmentally friendly to make as well as much cheaper).
Of course, it would of been more impressive if full details were diclosed online for people to take advantage of.
Is it possible to have your patent cake and eat it? The woman is clearly a brilliant engineer and deserves full credit for her work, she also states a worthwhile desire to help people across the world. So is it possible for her to obtain full commercial protection for her invention and then release all the details free for non-commercial use and reduced license fees for the third world? This would be ideal.
After all, no technology is going to change the lifestyles of poor people if they cannot afford to buy/license it.
On the other hand it would be unfair if she learned the Trevor Bayliss lesson the hard way - really clever little gadget swamped by low cost clones from asia from which he gained not a penny. As always I guess the big winners were the lawyers.
How many solar cells do you need to power a pizza oven, anyway?
How about two sticks and some kindling?
To respond to your other point.. do you mean functional lifetime or projected lifetime? I can easily see them in their projected lifetime compensating for the energy used to bake them. However, their functional lifetime may be significantly lower than projected, either due to natural disasters or the onset of Armageddon.
I'm being serious. Funny mods will not be appreciated. -Eric

for a lot cheaper. All I need is a bunch of guys with shovels, and a boat, and we can give the world's poor good old coal. It's our environmental priorities, which we choose, that make energy more expensive. If we all could tolerate soot filled cities, like London in 1880, we could have dirt cheap heat and light and electricity just by burning coal and sometimes making steam with it for power.
The point is, when people make announcements like this, its not to give poor people the most energy, it is rather to give them energy that is fundamentally more expensive, but to lower that window as much as possible.
So let's not say that we are giving the poor the "cheapest energy possible", because, that's not what we're doing.
This is my sig.
Link us up, bro'! Or are you just poo-pooing any progress in reducing the cost of solar cells yet again? Yeah, I did a little digging. ;-)

Hey, dude, I know a lot of really smart chicks. Some chicks I know are even nerds. So don't get your panties in a twist, babe.
mcgrew's razor: Never attribute to stupidity that which can be explained by greedy self-interest
Why? Let's say she didn't patent it, just released it to public domain. At the moment, the cells she has can be made inexpensively, out of cheap components. What happens when GreedyDeepPockets Corp decides to get into the business? It drives the cost UP, for everyone (for the raw materials at least). Now, let's say she does have a patent. She can decide who can produce it. Maybe she makes license terms that say for the first 5 years it can only be used to provide electricity for people who don't currently have it. Try not to get your panties in a knot every time you see the word 'patent'.
C'mon, EWAdams. You are really only person here who didn't noticed this "scientist" is damn hot chick? Why is it bad? If there was Usain Bolt baking solar cells instead of her, would it be also not correct to mention this guy is scientist *and* very fast, I mean "lets just keep on subject, his above-average physical abilities are not limitation of any kind in science and we should never mention it in 21. century!"

"She wanted to give the @2 billion people around the world who dont have electricity the gift of light and cheap energy."
What does "@2 billion" mean? "At two billion?" Maybe "~2 billion?"
It doesn't mean much now, it's built for the future.
Join the fucking twenty-first century.
This might sound like nitpicking, but people seeing women as equal to men isn't a "twenty-first century" concept. In fact, 2400 years ago Plato was already defending that, for example, if a woman is capable of governing a state, she should be allowed to, not blocked because of her sex.
We should stop being chronocentrists, which is as much a discriminatory state of mind as ethnocentrism. A given year, or a collection of years, has no attached value. Something happening "in the 21st century" isn't better just because it's happening "after" whatever came before. Ideas, such as that women and men must have equal rights, must be judged in themselves, not because of when they appeared, or when they became mainstream, or when they stopped being mainstream, or whatever.
So, while I agree with your sentiment, I must disagree with the way you express it. Calling for someone to change his behavior because of the "age" or "era" in which he lives is to incur in the "appeal to authority" fallacy. In fact, the only intellectually correct approach is to defend an idea by its own merits, not dwelling into its "ageity" at all.
Do more, or less, than this, and what you'll be doing won't be a rational defense of an idea, but merely a rhetorical one. In other words, politics, not reason.
Conservatism: (n.) love of the existing evils. Liberalism: (n.) desire to substitute new evils for the existing ones.
There are three utilities for a patent.
Using it to set up a monopolistic business and pricing the device higher than Cost+ReasonableProfit.
Selling it to an existing business so they can do so.
Patent trolling, supporting a leisurely lifestyle by placing a perpetual tax on those who would like to bring these devices to the citizenry of the world without continuing to productively participate in society.
Four: Keeping a big, greedy, monopolistic company (or patent troll) from patenting the design first, thus forcing everyone to pay.
Not every patent-holder is evil, and not every company that sells something is trying to rob you. Only most of them.
Do you realise that pizza oven does not need to use electricity, but wood? Using this process you basicaly can turn non-electricity house into happy solar energy house. That's why this is targeted towards the developing countries.
Right, but this is a case of that energy cost not being wasted cost - if you're doing this in a building that needs heating, there's your heat source. It's a furnace for the building, and it makes solar panels. Two uses for that same energy. As long as you don't remove the panels from the building while they're still hot, you haven't wasted _any_ energy in making them.
Co-generation has been around for a while - another example would be running the radiator for your generator into the house, blow air through it. What would have been waste heat, now gets dumped into the space where it's useful.
A lot of these "studies" that claim to look at how much something costs, consider just how much fuel it takes to run the oven or whatever, and don't consider the possibility of uses of "waste heat" like this. So yes, more piggybacking on your post than disagreeing with it - the payback time you mention might be even sooner, if they were gonna burn that fuel to heat the place anyway.
I suppose calling males 'guys' or 'dudes' is also sexist, then?
Seriously, some people are way over-fucking-sensitive. Probably not yourself.. but the people that decide on what's "politically correct" should be sent to mental asylums, or perhaps become antagonists in a Jane Austen theatre production.
which is totally what she said
