Proper antibacterial design, with maintenance, never provides a growth medium for whatever bacteria the winds bring in = no films in the first place. Sadly, human nature and bad maintenance = eventual fail mode = biofilms and mats can form that constantly shed bacteria into the air flow.
Quite doable, but they must make the cure last the life of the tower, so as the copper erodes, new copper is needed. In any event, there are many smart ways to make sure there is no continuing infection. The laziness of people can undermine anything
But, we forgot about lazy, cheap people. Yes, chlorine or hydrogen peroxidation would solve this, but require some method to maintain the antiseptic aspect. Copper sheeting might shed enough Cu ions for many years, but would ne replacing as it eroded away.
1 Capacitors hold charge between two plates separated by the electrolyte, and typically excess electrons accumulate on one conducting plate as a cloud. Once you reach a certain voltage, the insulation fails = punch-through. If self healing, the voltage will fall and the arc will stop before the charge is gone. If not, most of the charge will dissipate.
2 Capacitors are the mechanical analog of the spring, more force = more spring stretches, in the same way as you charge a capacitor the voltage increases as the charge increases. There is not voltage plateau of the the electro-chemical difference. Charge Q = 1/2 C * V * V, with Q = coulombs C = farads, and V = voltage. Not the square function, when voltage drops by half, charge is 75% gone, and vice versa. The voltage falls, so there needs to be a regulator for loads that need a constant voltage.
3. Since all surfaces are in parallel, charge and discharge can be very rapid, limited by path resistance and inductance.
4 Batteries change the chemical state of the charge/discharge compound, as a bulk material. This is inherently 25-100 times as much as a capacitor's charge. Even these capacitors face these limits.
That said, their speed and near infinite life will find them a role, just where they will fit? My fitbit runs for a week on a capacitor and charges very rapidly. Will an iPad or android pone run on that sort of a tiny charge? It is possible that e-ink devices as book reading displays will get to do this, but devices that transmit RF power use more than 1000 times the power of an e-ink reader in static mode, and 100 time in rewrite mode
Well, labor is full of badly educated louts who believe in fairies and homeopathy - what did you expect? If elected they might set back medicine to the days of the leeches and blood letting blades.
Smart crooks, stupid no-hope male clients bought this crap, and paid $$.in fooling themselves thay had a live fish, sort of an online whore house emulation. In a bricks and mortar whore house you get your thighs rubbed to get you interested. Now the lawsuit. They will pay to fight it, stretch it our for years, and may be win and maybe lose, and if Asley loses, the winners will find the money is all gone, and all their legal work went for nothing and the class action suckers will also get nothing, except being very very well known.
Universities have resisted higher wages for profs and admins, citing shortages in their budgets, so the unions are busily identifying new sources of $$ that they can cite as $$ for extra salaries and perks for all the union staff etc.
That is the correct analogy with respect to cable companies and customers. They send more flies to bite more often (higher fees), is it any wonder we are restive in our cages and when we break out of the cage, how reluctant we are to enter the cage again. Cable companies only thought is how to make a stronger cage (restricted competition via continuation of retransmission fees). Now we have the ability to have a cloud of DDT suppressing the flies ( diverse wide band internet suppliers, that will allow the netflix etc to completely replace broadcasters)
It is any wonder that more and more of us yearn to escape the flies.....?
In the old days, before Amazon, before the web, there were support staff, paid for by the margins on books and magazines. Now huge numbers of scanned books are traded for free on line = zero profit on those. In addition, Amazon's buying power and pricing policies have meant that the book shops no longer have hose margins. People come and look and ask, then go home and buy on Amazon or get an online file. Most magazines were sold far below the cost of printing, the ads paid the freight, and with paper magazines and story splitting there was enough ad readership to sustain the system. If 100% of ads get blocked = zero to pay for the web site, the site will fold.
Solution:- Sites can now render the site as a full screen jpeg, with the ads as part of the picture, unblockable. All they need is a click detecting frame for each ad.. If the frame is blocked, the system will not render the jpeg = you can not see the site if you deny the frame.
This will be slower to render, but with wide band = doable. The alternative = pay a fee to see a site.
There will be few altruists capable of funding a high volume site with zero revenue.
I wonder if it would be possible to fabricate a compressed net that could be shot from a bow for 25-30 feet that would open up and foul the propellers, which would ground the drone with minimal destruction. I agree with the property owners aggravation, but the use of a gunshot to deal with it is excessive.
Bureau of silly cops. I expect this outlet had no signage interdicting use, no trained spider chained there with a floss leash to bite charge thieves? I ask, why not....?
Hey, this is century 21. Gps lists. Digging utilities must provide information on where they dig to anyone who owns burried water, electricity, gas etc.
What do they do now for all these utilities?
I suspect the fiber signs were a form or bragging PR
For years the USA had a protected market. The lack of a foreign dealer market and parts support was a non tariff barrier to entry. There were also tariff barriers. Then the freight cost, since the handling cost was large.
Then a few large foreign makers decided to enter the market as a multi-year effort. The solved the parts and dealer probler, and developed RORO car carriers (RORO = Roll On - Roll off), where dedicated car carrying ships were made with the ability to drive cars onto special tracked and cleated decks, so each car could be tied down front and rear with fast latching equipment, they could be loaded as fast as drivers could drive them in with many entry points..
That cut the freight cost and delay down greatly .
Then they attacked the planned obsolescence concept, with cars that outlasted US cars by years. The USA tried to fight back with style changes, but the mileage laws that made the fleet efficiency increase over time, forced a streamlined efficiency = better drag co-coefficient = cars all started to adopt shapes mandated by the efficiency = look alike = less fashio,
Europeans and Asians have always wanted cars that lasted longer = less rust = better paint and galvanizing.
Yes, it was more important to waste money on workers wages and benefits, as the US auto industry went down the drain, than to make the vehicles a little better - thus opening the door to all those foreign cars that were better made, latsed longer etc, etc.
I had anticipated that more expensive, higher working load vehicle, might cost more and that they would make some attempt to make them last longer. Of course planned obsolence = planned rust out....

Well, the greatest power for getting rid of lazy incompetent people is the inability of management to keep its power to manage, = unions.

yes, ozone and UV = general cellular toxicants.
Hydrogen peroxide safer but more $$
Dig down, I did cast a wide net.
I found this on page 2.

but the 2P is correct, this should be a solved problem

Newly installed cooling towers deal with this, as this search shows.

So any disinfection must be followed with a permanent antisepsis program, say a little copper in the water?

No, there are lots of Earthbacks that have landed on Mars, the Democrats support them for their votes...
If this is a hand held weapon, I hope you wear gloves...
