Craggles™

Sandles for the crag allowing belayers to quickly slip them on and off. Toe area capped with light armour and good rubber soles for scrambling. Of course they have accessory loops for quickly attaching to bags for multi-pitch, Gone are the days of sore feet from belaying in climbing shoes, toe damage from catching a whip in flip-flops, or holding up your climbing partner by trying to find your approach shoes and a spot to put them on.

Change grammar so that the plural of a word ending in an s followed by a hard consonant has -es added to the end instead of just -s - e.g. waspes instead of wasps.

There should be a Bluetooth headpiece (over ear preferably) that has normal functions, but ALSO will replicate the "Note to self" feature, where you tap the main button, and say "note to self" then say what you want the note to be, and have it sent to your email. That alone would be a "killer product" for me. I miss this so much.

Headphones with an internal MicroSD slot or at least lots of internal storage to locally play back music.

Someone else actually not only had but went and made my one big idea - https://www.theverge.com/2021/5/30/22460964/vilnius-lithuania-portal-poland-connection-pandemic. The jury’s still out on whether it was a good idea.

I've got a few:

• In addition to fluoride, water supplies should be dosed with small amounts of lithium. Maybe LSD, too.
• Incel bounties: Anyone who has trouble getting laid can check into a facility where they are assigned a bounty equal to a set rate times the days they've spent in the facility. They can leave any time, but the clock restarts if they come back. Volunteers may show up and offer to have sex with a participant. If the participant agrees and the deed is done, the bounty gets split between the volunteer and the participant.
• Hard rationing of greenhouse gas emissions: every year everyone gets issued an equal amount of GHG vouchers that, in total, represent a safe amount of GHGs that can be emitted that year. Fossil fuel companies then need to buy these vouchers on the market and turn them into the government in order to get permission to extract the representative amount of fossil fuels. Doing so without permission would carry a severe penalty. This concept could be applied to water supplies, fisheries, and other resources as well.
• Imputed rent as taxable income instead of flat property or wealth taxes.
• No fares for urban public transit. Instead, a special property tax should be applied to real estate inversely proportional to its walking distance from transit stops.
• Reintroduce wolves to suburban areas to keep the deer under control.
• Electric airships instead of fossil fuel powered passenger jets.
• Nuclear power plants within or adjacent to urban centers, especially in colder climate regions.
• Gray water recovery built into homes and municipal water systems.
• Urine collection programs for phosphate recovery.

Free gender neutral public toilets, everywhere.

An app that removes businesses that you follow on social media that have closed automatically so you don't get anxious.

Something I have discussed before aside, a communication reform would be nice. The world of language is way too chaotic, with too many people who think their way of communicating should be universal and not enough people with that opinion questioning how they can change theirs in the name of efficiency/sufficiency.
