Pearl Sutton wrote:A poop Roomba!! What a cool idea!! I bet a classier looking version would sell to suburbanites to vacuum up dead leaves so they don't have to rake....

This idea is gonna bug my head... Edit to add: something like the portable solar fencing used for animals, that tells the poop/leaf roomba what it's parameters are. And the leaf one wants a mulching head, so it can carry more leaves in it's tank.

Can I get one that knows the difference between leaves and excrement? That shreds and "bales" the leaves, and stacks them together for me to pick up? And spends it's downtime making it's own payments by picking up walnuts?

* "Bales' is in quotes because I don't care if they're tied up. Just tight packed lumps sized between a brick and a sack of flour, that I can move without needing a rake. Easy to stack, (Seperated to dry, then restacked for storage.) easy to fluff out for mulching, easy to burn as a briquette after drying.

On the outside of your car, securely fasten a dime dispenser that operates hourly, and communicates via a blinking light. This device is to make peace amongst the owner of a vehicle and random urban beg-ers. When the small light is on, a dime is ready for the taking. When the light is off, a dime is not currently available. When a dime is taken, the device's one hour timer is started and a new dime appears when the timer runs out. Devices hold more than thirty dimes at a time. Beg-ers will learn the device's light communication in time. Vehicle owners can place devices opposite the gas cap. Devices will be secure, inexpensive, and not hold enough money to be a theft threat. A beg-er can get exercise and enough money for a meal or phone call. Instead of beg-ers standing in harm's way (like between two lanes of traffic, or the blistering sun), they can methodically take what they need as they need it.

You are the fruit tree and this is an urban forest?

A zipline/pully system to transport feed and other items down eroding hillsides. Think like ski lift, but smaller, cheaper, and easy to manage.
I doubt only Virginian farmers have to deal with drastic changes in elevation on their properties. Our house is on a hilltop and it is a several minute hike down to the valley where the fields are, along what used to be a path but is now eroded into a balancing act (slight overdramatization but you get the idea).  If there was a way to hook up a safe, secure lift (perhaps wind or water powered?) to transport our buckets of feed, building materials, or camping stuff down these hillsides...

There are so many things needed.

1.  A durable cheap coating for concrete that is both photo-chromic and thermo-chromic.  When the sun comes out and it is cold it should turn dark to absorb heat to melt snow off.  Transistion temperature about 45 degrees F.  When it is dark or warm the concrete should turn light in color.  Might be a paint or a stain.  Or it might be microcircuits the size of sand with built in photo cell, temperature sensor and LCD.  If made with thin flat layers the surface tension of water sprayed on the concrete might turn them into a flat surface to bond to the concrete.  Or it might even be something like a fungi.

2.  For solar collector PEX colored black for maximum absorption while being UV proof.

3.  A paint that radiates more heat than it absorbs.  The material exists now but has no weather durability.

4.  A cheap super black paint that is durable also for collectors.  There again exists but is hugely pricey.

5.  A system to do no turn aerobic compost but with heat sterilization at the start to wipe out dangerous pathogens and seeds.

6.  A cheap versatile magnetic drive pump with both high temperature(250 degree F or more) that ideally is modular, runs on a wide range of DC voltages and easily repairable.

7.  A way to recycle glass locally with okay economics.

8.  A way to recycle HDPE and make canal pipe with it.  

9.  A multi use small homestead turning system.  Start with something like a heavy variable speed pottery wheel except with changable heads.   Add a wheel with fingers and a finger barrel and it becomes a chicken plucker.  Add a frame holder and a different barrel and it becomes a honey extractor.  Stand it on end and it becomes a big bowl lathe.  add a film holder and turn it into a round bale wrapper.   Other uses?

10.  Add AI to the current open license gardening robots so weeding and insect control are possible.
