@pydsigner I don't like them as much. Personal preference. There's a niche for all types of notebook.
I have a really cool notebook made of crushed rocks instead of wood pulp, for example.

That's just absurd. I went to Energy Star's dehumidifier page and downloaded their spreadsheet... the products they list range from 1.85 to 4.2 L/kWh. According to his math, all of those products exceed the laws of physics by about 3 orders of magnitude... funny, he said the same thing about the water bottle...
That's why they don't use peltiers. A peltier works much differently than a compressor type system.
@boomzilla said in Dumb things being crowdfunded.:
I don't think that's true. Sounds like a solar powered dehumidifier. I suspect it will work very slowly (especially in arid environments), but I don't see why it would need to violate physics.
See above.

I just want mine to be graph paper. Also, my current version has a plastic cover instead of cardboard, which is kind of nice due to the flexibility.

You're going full here. Never go full .
Maybe you mean that they'll never get the performance they claim, and then we're in agreement and we're just quibbling over your communication skills.

No, Microsoft would release one
No, if Microsoft released one, it would be a combination shoe + boot + slipper, with all the downsides of each and none of the upsides.
- Too loose to hike in
- Too tight to relax in
- Too much traction to wear around the house
- Not enough traction to wear outside
- Can slip on, but need to lace it up
- Goes above the ankle, but only in front-- leaving your calf exposed.

Yes, and that it would take a solar panel much larger than what they show in order to get any water at all.
You have to drop the air temperature to the dew point in order to get any condensation. With a peltier device, that would take a hell of a lot of power.

True enough, but it is pretty much the only thing small enough to do the job.

Most kickstarters are dumb. If they weren't, they could easily get funding elsewhere.
The ones that aren't dumb are scams.
There is also a high proportion of expensive hipster crap.
The rest are people gauging interest in creative works (which seems to be a good usage of the platforms), and established businesses using them as presales to further fund their business and production (which is generally another good usage of it).

If Microsoft released one, when you'd want to take them off at the end of the day, you'd have to finish for them to install updates.
And then wait again the next morning.
-
@Zecc And they would always need to reboot to install updates when you are short on time getting somewhere.
The number of times that I have come home with just enough time to get on a teleconference call, opened my laptop, logged in and immediately had a reboot to install updates is not insignificant.

Hey, how about a self-filling water bottle that cannot possibly work without violating lots of laws of physics? Indiegogo has you covered!
In 24hrs, it'll be easy here... A storm is a-comin!
It might work in FL, but AZ is going to be harder. And I'll probably die of thirst before it "makes" enough water...

Which kind of makes part of their promise a complete and utter lie.
If you are an adventurer, you know the anxiety that comes with running out of water in the middle of a tour, the last thing you want is dehydration when you are miles away from home!
Fontus is a self filling water bottle that allows you to plan your adventures without having to worry about heavy water loads or where to find the next river or gas station to get your water supply.Fontus will set your mind at ease and might even save your life! It will keep you hydrated during your travels and ready for improvisation!

Yeah. Laptops can be too tempting for some people; knowing facebook is a click away, they can't help themselves. So they grab a notebook, head to a coffee shop, write for three hours, then come home and digitize it during the revision process.
I couldn't do that. I think much more quickly than I can write. I would lose lots of ideas.
I think more quickly than I write too. But I write more quickly than I type!

Naw, I think he goofed on this one. He'd have a point if it were indeed about crossing the boundary from liquid to gas - because then he'd indeed need all the energy.
But the opposite one is easier - you "merely" need to transport the latent heat energy out of the system. Which is a heat pump and a somewhat different calculation.
Though the Carnot efficiency for Peltier elements is still nothing to write home about (about 0.1, to be exact)
-
@Rhywden Fair enough. I am not a scientist. I trust that you know a lot more about the subject than I do.
-
@Polygeekery I'm just a bit tired at the moment to do the necessary calculations.
But it's the reason why heating your house directly with electrical energy is a dumb idea - transporting warmth from the outside into your home works much better (yes, even when it's cold outside ;) )

It is a peltier, they have said so elsewhere.
-
@Rhywden based on this
http://www.marlow.com/resources/general-faq/14-how-efficient-is-a-thermoelectric-cooler.html
Typically, the coefficient of performance, heat pumped then divided by input power, is between 0.4 and 0.7 for single stage applications. However, higher COPs can be achieved with optimized, custom thermoelectric modules.
The latent heat that would need to be removed (it doesn't matter whether you're adding or removing it if you're using a peltier device) to condense 1 L of liquid water from vapor would be 2264.76 kJ, which is about 541 kcal. He still doesn't account for the efficiency of the peltier device, i.e. the energy required to actually move that much energy, which isn't one-to-one. But if you assume the ratio between heat energy pumped and energy consumed in pumping it is around 0.4-0.7, it actually takes maybe twice as much energy than he calculated.
So basically, despite his mistake, he's at least correct in his finding: a peltier device, at least if it's pumping only around 0.7 kJ of heat for every 1 kJ of electrical energy it consumes, would not be suitable for the job. That page did imply that better efficiency can be achieved, but didn't mention what the upper limit on that would be; probably still far lower than compression-expansion based refrigeration.
-
@Polygeekery hmm, one drop of water per minute? A drop is what, like 0.05 ml? That's somewhat believable, but it'll take... a rather long while...

@anotherusername Yeah, there have been other videos done on the subject.

Here's what I want:
Someway so that when it's hot outside, to capture that heat and store it-- then slowly release it when it's cold. It's like free heat! You don't have to spend energy to heat your house!
Hang on-- I'm being told that the act of storing might require energy. That sounds dumb, the heat is just sitting there and--
Hang on, I'm being told we need a way to pump the heat into our containment unit. Fine, we'll just use some sort of pump. I guess it'll need to be electric powered or something. Okay, so we'll use a BIT of energy just to capture the heat. Once it's captured, we have free energy!
Hang on-- I'm being told that capturing heat is kindof hard, because-- what's that-- entropy? Heat escapes into the surrounding air? But it's in a container-- insulation, what's that? Fine, we'll insulate it so the heat will stay in there for months until winter comes around. FREE CHEAP ENERGY!
Hang on-- I'm being told that insulation is actually quite expensive. Well, sure if you want like-- I dunno-- quantum carbon or something? Can't we just use sustainable insulation, like recycled foam? We'll do that-- extra environmental protection!
Hang on-- I'm being told that to insulate for that long, we'd need a massive amount of foam, and it will take up an entire city block instead of someone's basement. Okay, well, instead of using lots of insulation to capture just enough heat, instead we'll capture a LOT of heat, put it into a slow-releasing medium, then use that slow release to heat the house during the winter.
Hang on-- I'm being told that even if we take the most dense commercially available metal we can find, in order for it to heat up enough to slowly release over the entire winter, we'd have to heat it to hundreds or thousands of degrees. So-- we'll have a molten lava pit in our basement? Umm... okay, maybe instead--
Hang on-- okay, so what if we used chemistry. Like, if we captured heat from sunlight and other energy sources-- and instead of just storing the heat, we used the energy to create some other form-- something carbon based. And then later we used a separate reaction to break apart the carbon and release the energy, which will come out in heat. Yeah!
hang on-- I'm being told I just reinvented firewood. Well, fuck, we're screwe---
hang on-- I'm being told my kickstarter just got funded 257x over budget. Well, fuck this, bitches, I've got my money. Bye.

The Triton Artificial Gill is another one that will never see the light of day. It claims to be able to remove the oxygen from water, so that you can breathe without SCUBA.
Then they came clean and said that it would actually use canisters of liquid oxygen and refunded all of the IGG money. Over $900K

The big problem is that it needs a lot of energy. So it would be too expensive, unless you had your own micro nuclear reactor.
