@slrpnk.netin software these days it is: good, cheap or fast; pick one (if you are lucky [usually things are just bad, expensive and slow as f&*k])
Well you didn't specify additional cargo or other reasons for limitation.
For example if the issue is travel time: electric motorcycle if the issue is cargo: electric bike with travel trailer if both travel time and cargo: gas to electric conversions are affordable (with the batteries being the highest cost [and the determining factor for range])
basically the less mass needing to be accelerated, the less energy required. The lower the acceleration acceptable, the less energy required.
Treat it as an engineering problem to solve or improve upon.
Yes, if that is what is needed to provide for my family. But my job isn't hard physical labor but more sitting in meetings and writing code.
Skip the batteries for now, get a few solar panels and an inverter. Skip depending on a fridge until you can get batteries in. But more details about your must haves, want to haves and nice extras would enable more exacting calculations.

Well assuming 70mph travel speed as an upper bound and a 1 hour commute, we can safely assume a 140mile e-bike range would be sufficient. Assuming you are willing to pay those savings forward to help others reduce their car use; collective investment in improving your situation would be mutually beneficial in the long run.
Guerilla gardening
Guerilla gardening is find a scrap of land that’s being wasted and turn it green, in the hopes that whoever owns it won’t care or can’t be bothered to tear up what you’ve planted.
Whatever it is that you plant, if you intend for it to be a source of food or shade, you should intend for it to be permanent, and able to survive without your continued care. Ideally fruit or nut trees, berry bushes if trees are not an option and if all else fails perennial vegetables, herbs or flowers. Even something as simple as clover is going to help your local pollinators. Time is a big factor. Do you expect your plants will last a season? Will they get dug up next year? You don't want your effort, or these plants, to go to waste, so don't commit a row of fruit trees to the earth when you know soon enough they would be destroyed mindlessly. If all you've got is a summer, go ahead and plant annuals. Throw down those tomatoes, plant some corn. Be showy, so the locals begin to realize what could have been.
Regardless of how long you expect your gardening to last, how you go about it is another key idea. There are two simple ways: you belong there, or you were never there.
You Belong There:
This is an easy enough outfit: jeans, work boots, and a reflective vest will keep most people from second-guessing you. If more than one of you are out and about on a piece of land, try to match your shirt to add even more legitimacy. Cap this off with a truck and some equipment and you'll be virtually invisible to anyone. Make sure one of you is doing all the work while the other lounges by the cooler with some Oakleys on.
You Were Never There:
Obviously enough, here you're trying to not be seen. Plant at night or in a secluded area. Guerilla gardening doesn't mean you're just taking over a median or a patch of grass beside an exit - you might be taking advantage of extant green space, as well. Say you've got a patch of park that's disused, and nothing but grass? Make it worth the space. And again, it doesn't have to be an orchard to be successful guerrilla gardening. Red clover can go a long way toward improving soil, and helping out the area bee population.
If you're planting near roads or industrial areas, it's best to test the soil before you try to plant anything edible. If the soil is in question, there are a variety of plants capable of phytoremediation - meaning the plant can help clean up the place. Just be sure to pull the plants and dispose of them properly rather than let them decompose in place, thus returning the contaminant to the earth.
and how did the experimental test of the calculated results turn out?
I would be quite interested to learn more.
depends extremely heavily on the efficiency of the panels.
You would need to exceed 84% solar to electricity conversion efficiency to make that conversion pay off.
As chlorophyll has an approximate 90% maximum interception of 400nm to 740nm light and your panels would be getting the extra energy from frequencies outside of that range. The energy of a photon is determined by hc/λ, with the result that the energy of a blue photon (400 nm) is 75% greater than that of a red photon (700 nm).
Anything less than that would be a net loss unless there is a significant increase of ultraviolet light in the near future.
Well yes there is a hard limit, we just don't know what the exact carrying capacity is (there may be multiple different values).

Well there is a very good reason why modern nuclear reactors have a negative void coefficient (you just turn off the neutron source and the reactor naturally turns itself off
Or if really paranoid have a supply of Xenon-135 handy and that reactor will be shutdown in microseconds (which by the way is naturally produced by the reactor itself and why early prototype rectors kept turning themself off after running for a bit)
