I used to own a large ranch in Puna district that had this very crack run through the middle of it. I once crashed a bulldozer into it and got it stuck sideways about 50 ft from the surface.

After dropping a rock below my feet and couting to 10 before I heard the splash I discovered that the crack went all the way to ground water about 1100 ft down. That rock could have been me!

There aren't enough Physicians, they don't make much and they all seem to be working 12 hour days but being paid a salary that would equate to an 8 hour day.

Doctors see downsides of a universal coverage are mostly about loss of autonomy and increased demand because when care becomes free demand rises along with pressure to expand access without extra staff.

The southeastern Wisconsin system takes the address idea further, the address grid is tied back to the Milwaukee grid. A local official gives the example W156 N8480: roughly 156 streets west of the origin and 84 blocks north. He specifically notes that you can use the address to determine whether you need to travel north, south, east, or west. Wisconsin's statewide NG9-1-1 standards even explicitly recognize these two-direction grid addresses, giving W180N8085 as an example.

That is, in a navigational sense, superior to ordinary street addressing.

Take something like N90 W17567. Once you understand the system, you already know approximately where the destination is: the road lies about 90 blocks north of the baseline, while the property is about 175.67 blocks west of the north-south baseline. The address is essentially a human-readable coordinate pair.

In other words, if someone gives you an address like N90 W17567, and you understand the grid, you immediately know roughly how far north and west the property is without having to look up the street or pull out a map.

Attending church can have negative consequences because religion promotes belief in unprovable claims, building life on a false premise: since the central claim isn’t true, the practices and rules around it may seem hollow or misleading.

Religion discourages critical thinking, consumes time and money, enforces conformity through social pressure, and expose individuals to guilt, shame, or manipulation by institutions with histories of abuse or corruption.

Floating the idea of a youth simulator (like a VR app with integrated exosuit) could be used to measure physiological and cognitive age gaps. It might be valuable for science and medicine, but also for things like understanding empathy/social knowledge or understanding workflows/applied knowledge.

Geriatric simulation is interesting, but couldn't this also be applied to pediatric simulation for improved vision, hearing, strength and endurance? I don't see any show stoppers preventing the development of a youth-augmentation exosuit blending AR sensory augmentation, powered exoskeleton support, haptics, and AI adaptive controls.

I'd like to see a global foundation managing open standards, with local operators (commercial, nonprofit, academic, government) running radars, and multi-layered funding (enterprise subscriptions, public-good subsidies, and co-op models) sustaining the system. It becomes the “public utility of weather data”, much like the internet itself.

I agree, personal energy abundance is disruptive: * Utility decentralization, economic liberation from near zero marginal cost of energy after initial investment. * Geo political: reduced dependence on hydrocarbon fuels, energy sovereignty * Transportation: every home is becomes a 'gas station' to recharge EVs, or for the EVs to charge the house in case of low house batteries (as opposed to ICE generator) * Climate: no hydrocarbons burned => no pollution * Technological civilization: abundant clean energy creates a feedback loop of innovation in energy production, storage, AI and networking * new business models from energy as a service

Truck at 100% = 131 kwh, Minus 10% loss in transfer = 120 kwh House using 12 kwh/d = 10 days, up to 24kwh/d = 5 days

Local conditions are typically partly cloudy/rain but still system producing more than can be used.

I installed a similar EG4 inverter and battery system and had a similar experience. The big problem I ran into was that EG4 inverters are NOT compatible with my state's power grid (Hawaii) but because I had so much power, it turned out I never needed to connect to the power grid but I am loosing out on selling power. (Check with your local power company before buying!).

Another problem I had was that a week after installing, one of the TIGO units burned up and started a fire that burned a hole in a solar panel. I only noticed the problem when I saw that one of the solar arrays wasn't putting out power. Replacing the defective unit solved the problem.

Also, I had assumed I would need a generator to power through consecutive days of dark clouds but I instead opted for Ford's Pro Charger Station which has a feature that allows you to power the house; no need for a generator. However, its been over a year and not once have I needed this.

My big takeaway is this: having energy abundance is the good life when you have all electric appliances. My EV (a Ford Lightning Truck), hot tub, AC, water heaters etc have been running over a year with no problems and zero costs after the initial investment.

Yes, this wasn't economically feasible 10 years ago due to the rapid improvement in batteries, inverters, heat pumps for air conditioning and water heating, etc. I've been living off grid over 20 years but its only recently that its at least as good as a connected 200 amp grid power service with ample 220v for residential needs.

Yes, utility vehicles are by definition not ideal for personal commuting.

Personal energy abundance and off grid independence is the good life and it means using all electric appliances and vehicles, heat pump and hot tub, powered by nonpolluting energy generation.

As the article alluded to, scale is important for this to work (although I get by fine using only thirty 400 watt panels (12kw) and this covers less than 30% of my roof).

As a remote worker, not commuting daily large distances is key to this system working. If I had to commute 60 miles every day I would need additional 10-15 panels to power the Ford Lightning EV truck, and if I was charging at night I would need six additional 100A 48v batteries.
