http://en.wikipedia.org/wiki/Caffeine gives about 100 milligram per cup of coffee.
Assuming 100 cm^2 exposure area, you would need a milligram per cm^2 for a "cup of coffee equivalent". That's 500 hours ("three weeks")
And that is assuming that this spray is equivalent to whatever van de Sandt er al used to get caffeine on the skin (I would guess they applied way more than a spray would apply)
On the other hand, high pressure spraying (better called jet injection; see http://en.wikipedia.org/wiki/Jet_injector) might work. I think that would require FDA approval, though.
"Nothing to see here, just more snake oil!"
Maybe it's time he gives back the $100,000 and enrolls back in college. For anyone unfamiliar why it's such a red flag that someone voluntarily associates themselves with homepathy:
http://en.wikipedia.org/wiki/Homeopathy
Homeopathy is a system of alternative medicine originated in 1796 by Samuel Hahnemann, based on his doctrine of similia similibus curentur ("like cures like"), according to which a substance that causes the symptoms of a disease in healthy people will cure similar symptoms in sick people. It is widely considered a pseudoscience.
The remedies are prepared by repeatedly diluting a chosen substance in alcohol or distilled water, followed by forceful striking on an elastic body, called succussion.[7] Each dilution followed by succussion is said to increase the remedy's potency. Dilution usually continues well past the point where none of the original substance remains.
Basically, if you have a cold:
1. Start with a poison that causes cold symptoms
2. Dilute it with water
3. Repeat diluting it with water until the most sensitive scientific instruments can no longer detect the original substance
4. The water then has an "imprint" or "spirit" of the original substance which will cure the cold
On the other hand, if this thing works, it surely does so by placebo, but due to the harmful effects of actual caffeine usage, placebo might actually be a major benefit to the consumer.
I love the irony. Peter Thiel was trying to make a point with his "College Dropout Challenge", but this product was really developed by someone with a graduate-level education.
Anyone can drop out of school, find a partner,
and start a business.
I suppose with context it reads a bit differently though; Anyone can drop out of Harvard, take a expedition to
Antarctica, meet a venture capitalist on the boat,
and use your dad's PhD-level chemistry knowledge and
infrastructure to start a business selling snake oil to
gullible people.I guess they've never heard of tea?
The spray will cost about $0.38 per dose.
The competition isn't coffee or tea but caffeine pills, which are cheaper and about as convenient. It looks like you can get 120 100 mg pills on Amazon for $5, or $0.04 per dose. I don't see the benefit of a spray as opposed to pills.
You have a good point, but 100 mg is a good dose of caffeine for people that are sensitive to it. They would find themselves cutting the pills down for lesser doses. The 100 mg caffeine pills I bought on Amazon are very tiny and would be very difficult to cut without a specialized device.
What problem does this solve? Sleep deprivation for people who don't drink soda, tea or coffee?
I get the spirit behind the idea of giving kids money to tinker, but this creates what's equivalent to a programmer who has only learned from stackoverflow and w3schools. There is a lot missing that's still part of the standard college curriculum, and the worlds problems will most likely need just as much theory as practical understanding.
Maybe it's because the person funding them came from Stanford.
I can't help but be reminded of the Caffeine Patch scene from Meet the Robinsons, though.
Mr. Willerstein: Dr. Krunklehorn, I know you're very busy at Inventco Labs. And we're just so happy to have you as a judge.
Lucille Krunklehorn: It's my pleasure, Mr. Willerstein. Hey, you never know, one of your students may invent the next integrated circuit, or microprocessor, or integrated circuit. Oh wait, I said that already. Well, I just don't get out of the lab very much. Is that a bowtie? I like bowties. I haven't slept in eight days!
Mr. Willerstein: Uh, well then, can I get you a cot or something?
Lucille Krunklehorn: Nope, I have the caffeine patch. It's my invention. Each patch is the equivalent of 12 cups of coffee. You can stay up for days with no side effects. AHHH!!! Sorry.
Frankly this is really disappointing to me, it seems like Thiel is supporting people who support his libertarian views more than actual visionaries. There are lots of people who would be well served by this program, and this guy doesn't really fit the bill in my opinion. It may as well be the 'Peter Thiel drop out of school to create trouble for regulatory agencies I don't agree with' scholarship.
Reinforces the homeopathic points I suppose.
