Ask HN: Share an idea?

Rooftop solar has really taken off here in Australia, and around 20-25% of houses have a solar inverter. Is it practical to build a cheap rooftop wind-power harvester that plugs into the inverter?

An Amazon for renting things. All the top Google search results looked antiquated..

edit: my search query was just "rent anything"

Pay for full time, beat-walking emergency medical technicians in shitty neighborhoods. This would prevent a lot of unneeded hospital visits and offer basic health services. A lot cheaper than 911 calls. I imagine having people on the ground would prevent a lot of problems.

Verlet physics engine that supports

1) collisions

2) contraining particles by the area/volume

3) creating 'areas' that create and destroy particles based off forces effecting it and whether or not the two lines connecting two particles are parallel

Netflix, but mostly decentralized. End users can be paid to allocate part of their PC's storage toward movies and shows that they stream to their neighbors, taking a lot of the load off the public backbones and central servers.

Of course, these are encrypted and only decrypted (transcrypted?) when they're transferred to someone nearby, intelligently based on `tracepath` or something. My thought (may or may not be feasible) was that the central server only gives you the public key for the data, and then provides the private key and a new public key when the data is transmitted. I'm not sure that's even possible with any level of secrecy, but if so it would remove a lot of redundant traffic and I imagine you could pay people less than you'd save on bandwidth/peering if you could just pay them to P2P content (securely).

Get theaters involved in the initial distribution since they're everywhere and have digital copies (and probably decent pipes).

Basically, my internet got really crappy every day at about 6 PM and I imagined that 90% of my neighbors were streaming the same episodes of Breaking Bad, and it bugged me that it wasn't just sent once and the distributed locally.

Indoor almond farms

I don't mean as a hobby. Industrial scale, genetically modifying the almond trees for better indoor results.

Global demand for almonds will continue to vastly outstrip what California can handle via traditional outdoor growing. That would have likely happened even without the drought. The water requirements will place a cap on the almond industry's growth. The solution is drastically more efficient indoor growing.

A mobile app platform based on images. Keep a basic JavaScript bookmarklet to decode the images into HTML, so they become browser-based apps. Store everything in the 50MB of cache-manifest. Use the same apps on iOS, Android, etc. Evade parental controls and device restrictions on app stores. Copy app-images directly between phones. I call it "Fondant", meaning "chocolate coated". Because I can have chocolate coated Apple, and chocolate coated Jelly Bean/Lollipop, etc.

A product hunt type website but for adding features to current app/websites. User can thumbs up or down a feature request, and can also thumb-up a request with some small money tagged to it. The money collected will go to a non profit.

1) An application that connects restaurant chefs and managers to local farmers. Local farmers could upload their goods for the week on a marketplace board, and chefs could find things that they would like to cook with for the week and buy them. Typically chefs meet local purveyors at farmer's markets, but for small enough producers, it would save them time and money to just have their goods bought directly without having to go to a central market and run a stand. Chefs would be able to order local goods similar to the way they order through Sysco or FSA.

2) A dribble-like site for artisans. A site to showcase and upvote artisan work and hopefully drive business to them. Baked goods, building airplanes, cedar strip canoe building, kinetic sculptures, etc.

Problem: Advertising is a big industry. Billions of dollars are spent to bolster brand awareness and drive sales. Increasingly, advertising is digital as consumers spend more time on phones, computers and tablets. Social platforms like Facebook exploit user data for enormous profit, while all the user gets is a “free” product. There is an opportunity for users to reclaim a significant amount of this value, and in doing so realize a greater sense of worth.

Mission: To measure and honor the value of every individual.

Vision: Corporations and Individuals providing value directly for each other.

Product: A URL shortening service for individuals to monetize the content they share. Monetization occurs via an ad featured between the platform sharing the short url (e.g. Facebook) and the site the short url takes the user to (the content being shared).

Shazam for fonts. Point your phone camera at some text and it tells you the top N fonts it thinks it is with C% confidence.

Niche market for graphic designers.

There's the website What The Font [1], but it's not a super user friendly app like Shazam.

I think the hardest part of this would be the huge amount of time it'd take to get a good dataset and train whatever machine learning model you'd probably wind up using.

    1. Foo Bar Lite Italic - 99.1%
    2. Foo Bar Italic - 97.2%
    3. Baz Bar Lite Italic - 97.0%

    ... etc maybe give the top 10 or so ...

- Startup: create a universal and convenient micropayment system that would allow content creators(writers, comics-artists, video creators) to monetize their content. The problem now is that current systems suck, and each website has it's own, so that it's not convenient for users to pay for content, they have to enter credit card, or go to paypal, etc. There should be a nice embeddable button that allows users to pay for watching a video or reading an article in one click, on any website. Or maybe something even more elegant and convenient.

- Startup: xprize meets kickstarter. Or a reverse-kickstarter. You create and back the project first, and then anyone can execute it and collect the reward. People come up with projects they want to see happen, submit the idea. Anyone can vote on the idea by sending some money. As a result you have a list of user-created project ideas, ranked by how much money people deposited on them. Anyone who completes a project gets all the money.

- Project: A convenient website where users can add feature ideas, vote on them, and discuss implementatuon. It would be a convenient way for developers to prioritize which tasks to work on. Probably connected to git. Basically like submitting issues, but it's feature ideas and it's ranked by importance.

- In-browser markdown editor like on gitbook.com. Please somebody make this. Ideally it would be open source, but I would totally pay for an opportunity to use it on my website.

- slant.co, but for things other than tech. Movies, books, music, whatever. Or a similar open-source system so that I could spin up my own website with this.

- Awesome open source chat that I can embed on my website. Like chapp.is or gitter.im

- ELI5 for computer science and programming. Explain linear regression, ANN, and other complicated concepts in short, simple terms.

-A robot simulator programming game where you control a virtual robot with your code. Targeted to CS and AI students. You could use this game to practice algorithms you are learning. Challenges(levels) are somewhat similar to AIMA exercises, or can be taken from berkeley AI class curriculum. Later you add a "competition" feature, where several teams program their robots to fight each other. Check out Screeps and Starcraft AI Tournament for inspiration. (the whole game is in the browser, robots are controlled with REST API so you could use any language.)

Send me an email to raymestalez@gmail.com if you are interested in working on any of these. I know Django, I can contribute, especially if it's open source.

I sometimes even registered the domains, e.g. toothing.org The name offers various cell phone games, even the toothing hoax itself.

The next odd idea requires expert knowledge in Babylonian contracts. Every change of ownership without a contract was theft. Contracts involving people required a cancel clause for each side. And ownership on people without contract was punished by death, as illegal slavery. So most contracts are marriages. The contracts are highly formalized, so one can use them as templates and exchange the names. Print them on a clay tablet, burn them, and send them by mail. I'm sure marriage contracts would sell, especially those with the cancel clause: "and when she says you are no longer my man, he can throw her into the river".

The 3rd and most challenging idea would be a project and freelancer site that does not suck. Where projects, prices and skills do not race to the bottom.

And last shameless plug about something real You can contact me on #o3db @ irc.freenode.net - currently developing a Browser-4GL in Scheme.

For the love of God, someone create a World of Warcraft where the quests are educational. Instead of "go kill 8 green dragons" the questiver says "Mata a 8 dragones verdes". The immersion and addiction to progression (i.e. unholy motivation) would have us speaking multiple languages in no time.

Please. I'm begging you to take my money.

Amazing post-game experience for recreational athletes.

I play soccer recreationally. I've easily played more than 1,000 games and all I have post-game are memories ( which are nice ), but I feel we could do much better.

I have a vague idea for a solution - but it would involve drone-filming all my recreational soccer games, and then have the content edited/produced - so I could see al my plays, everyone else's best plays, and so on and so forth.

It would be really interesting because it would also augment the social in-pitch experience with post-game online socialization.

What do you think?

1) A lightweight CRM for friends. I'd love a tool that takes the teachings of someone like Keith Ferrazzi and builds a simple tool around making it much easier for me to be a better networker. Facebook doesn't quite get the use cases right, and neither does linkedin, and other CRMs are too heavy weight to be practical. Maybe with tips on managing my professional networking life in addition to my individual relationships (eg, suggest among my network a group of 4 that would make a good dinner party, and see that I haven't done a dinner party in a while and suggest to send an invite to the group). Or, tell it a handful of aspirational goals (work at Google, start a company, go to YC) and have it suggest a path to get closer to that goal by probing my network, discreetly connect me to others with similar or complimentary goals, suggest when I can help someone that has a goal that's close to my expertise, etc.

2) It would be really cool to get the 'magic' of the command line into the hands of everyday people that don't even know what it is. Magic sort of does with with SMS. I'd love to see an app toy that you totally interact with by emailing it. Then you could email it for all sorts of automated things -- :bcc the app to log data, send it an email for reminders, simple commands could be parsed and understood. It wouldn't have to do a bunch of NLP at first, you could be strict about how the data needs to be formatted for it to work.

3) This one is nebulous, but I think software discovery for the enterprise is really broken right now. There is still WAY too much outbound phone sales and old fashion 'network' selling going on. There should be some place I could go as, say, a sales ops manager to check out the best software eating the uses cases for sales operations (Ambition, BaseCRM, Yesware, etc etc). Maybe it's product hunt style group voting. Maybe it's a curated, impartial look into the 'stacks' of the industry companies that are considered 'best in class'. Maybe it's something looking at Google trend data and finding 'momentum' sort of like Mattermark. Maybe it's a 'pagerank' style connection map by looking at VC investors and the 'client' pages of startups. I dunno the best way to get good information that scales and nimbly identifies new ideas when they emerge, but if you figured out that problem you'd be solving a huge, very real problem and be in the middle of what will be billions of dollars in $ shifting around in the next 10-20 years. Search like Google works when you already know what you want, but it's really hard to distinguish the signal and noise with all the new tech and tools and toys emerging to take over different use cases for large companies. And the people in the large companies that need to know this information often don't have enough time to do the research or even where to begin.

1. deliver organic and healthy food at airports and hotels. When a user checks in for boarding pass, the delivery is ready. One delivery per flight..

2. building your own store curated from your favorite brands only. Every user gets discount on their fav brand and there is a limit to number of brands

3. Hire a local "expert" to build your itinerary when you are visiting that local's town/city.

4. An new email platform built with UI in mind for non-personal emails like newsletters, marketing offers, etc.

happy to work with or share more.

Here's my pet idea for a hardware product I'd totally use:

A Google Glass like device without most of the functionality (no camera or mics) or processing hardware (doesn't have to run its own OS), except the display (this should cut down costs quite a bit and make it a bit more feasible to manufacturer and purchase than Google Glass itself).

You connect devices to it using Miracast and/or some other wireless display tech and extend/mirror your smartphone/laptop displays.

It can serve as a portable multi-monitor setup for productivity, or a simple portable heads-up display for entertainment (video playback, reading) or utility uses (navigation).

That'd be the MVP anyways. In future revisions you can maybe add things like a mic and/or camera for things like augmented reality and voice control, but figure out how to offload the processing to the master device (laptop/smartphone) rather than dedicating hardware to it on the device itself for affordability and battery life.
