I hear this every fucking day this time of year.
All these defects running around with their sniffles, hoarse throats, and complaints that go with them. Then they run for their Claritin, and bitch and moan about it still.

I've come to the conclusion, and the hypothesis brought here for discussion, that seasonal allergies are a symptom urban/suburban childhoods.
Individuals raised in the country seldom have allergies. Most bugmen from the city cannot stand to be outdoors this time of year.

Quite frankly, it's downright pathetic to be subdued by something as innocuous and widespread as pollen. Amazing how animals in their natural habitat of the wilds are not affected.

Ive long contended the world isnt running out of resources we are humans just lack the will power to think big and think outside the box to tackle alot of problems.

for instance the world has oodles of empty land. for example Russia is the largest land mass of any country yet majority of it is covered in ice/snow.
sure it wouldbe costing a shit tonne in sunk costs... but why not just turn a good chuck of cold land mass in farm land via greenhouses.

same could be done in over open and large land mass spaces.
example australia. its hot AF,very little green sapce but they also need fresh water to grow crops, why not use the heat of the sun to desalinate the salt water in I undo glass tubes or whatever and use that to grow crops.

just build more lakes or agrofish farms, hydroponic farms for growing crops too.

A lack of land, water, seeds, and fertilizer has literally never been the reason for why people struggle with food. The inequitable distribution of wealth means that there's more than enough money worldwide to provide people with the financial ability to afford food wherever they live. Arable land and freshwater exists in sufficient abundance to sustain many times the current world population.

But it's even more complicated than that since oftentimes areas that struggle with hunger are also stricken with famine and lack of infrastructure. In which case, billionaires giving the villagers money does nothing if the farmer's markets do not have produce. Feeding those people would amount to building roads and airlifting crates of food, which is a bit of a logistical nightmare that most governments wouldn't do. You also have to factor in the fact that hunger also exists in places with conflict - governments are reluctant to start foreign aid in warzones where militants can kill their nationals.

tl;dr we are nowhere near desperate enough to turn a frigid wasteland into an expensive high-tech green house. hunger is a lack of resources in certain places, not on a global scale.

Smart concept. It would tie into the whole software over hardware "thing" we have nowadays. One cable, infinite uses. Building it would be the easy part though. Not only you have to program some software to make it recognize each and every hardware you dip into it, but you need to make it so that the act of figuring out the kind of cable you plugged into it doesn't potentially fuck up any other kind of cable. Like, to figure out what kinda shape it needs to be it has to either:
1- change shape and monitor some parameters
2-run some current somewhere
Or possibly both. Both of those things can fuck up a connector and/or the device connected to the other end of it.

Well, a flywheel in a vacuum will only have trivially small amounts of energy loss. If you assume that the execution, materials, and place you install it are all perfect it could be nearly perpetual, and by that point you would be more worried about weird obscure things like quantum fluctuations.

Actually implementing something like that would obviously be impossible. There are designs for perpetual energy machines which take friction into account, they're just impossible for other reasons.
