Zero cost production energy .

This.

A series of generation for electrical systems .with maitanance concerns being addressed robotically.

1 Geo thermal systems. This I rank as the best .

The design is do drill a dry hole incased with pipe the hole needs to resend to a depth of at least a mile to access the higher temperature rock nearer the lava chamber within the crust.
The water is filled to a closed system.
As the colder water in the surface surface sinks and the hot water within the depth rises a natural river current forms within the closed well system .
a series of generators fill the pipe to spacing of one every foot. This transmits to a conduits beside the pipe and resemble the human spine and nerve context as a main supply for the vary to the giga watts depth temp of rock and diameter of pipe can be adjusted to the need of NYC vs ... Lowell Massachusetts. consumption of larger cities eliminating supply cost for closed grid systems.

Robotic features can travel within the conduit repairing stucture failures as necessary.

Vermont digestor.

Sewage a primary concern for cities can be handled by this system
Sewage containers high volume of methane the director turns the sewage methane is released collected and can be burned in cars trucks buses and other transportation systems leaving a green house gas neutral foot print .

Water .

Reverse osmosis.

All wayer becomes pure water.

These systems as deployed will advance our world into an advanced Civilization and further the milinia goals as we progress to the 2030 summit.

A little YING for that YANG

Did you know that "pure" water could cause harm?

There are disadvantages. Many reverse osmosis systems remove the good with the bad. Iron, calcium, manganese, and fluoride are a few of the beneficial chemicals that may be removed, depending on your system. Removing these essential elements from our drinking water doesn't pose much of a problem, since a well-rounded diet will provide these as well. However, many Americans do not eat a diet that is rich in vitamins and minerals. If these people also drink demineralized water, then they are more prone to vitamin and mineral deficiency.

Additionally, when used for cooking, demineralized water was found to cause substantial losses of all essential elements from foods such as vegetables, meat and cereals. Such losses may reach up to 60 percent for magnesium and calcium, 66 percent for copper, 70 percent for manganese, and 86 percent for cobalt. In contrast, when hard water (not treated with reverse osmosis) is used for cooking, there is minimal loss of these essential elements.

Also, for every gallon of pure water filtered by RO there are 3-4 gallons of waste water produced by backflushing the filters.

Digested methane gas production requires substantial capital investment. A great deal of the methane produced is required to heat the digester to keep it operating. But there is extra that can be harnessed at a cost. Digested methane gas to hydrogen fuel cells is an option. Only 2% of wastewater treatment plants utilize digesters. Why?  Currently not cost effective.

Lithium ion battery backup systems will soon be replacing generators at large commercial complexes such as casinos. The drawback now is keeping them cool and preventing fires! Thermal runaway conditions are an issue for large banks. 

New York would have to drill a hell of a lot deeper than 1 mile to hit magma heated rock. This can only be done near volcanoes or hot springs. 

Geothermal is used by individual households that bury pipe in the constant 50 degree F ground. Circulating air in the summer cools and pre-heats winter air. Again, capital costs are prohibitive.

So how do we get these processes moving? Easy, the Biden administration will decrease oil production, raise taxes on all fuels, and wa-laaa, not cost prohibitive anymore! Nevermind it will push us to a huge recession, make us non-competitive with manufacturing countries, etc.  

Simplest machine is taking water electrifying it reducing it to hydrogen and oxygen burning it to create steam to push a steam turbine then using heat extraction cool the steam and fertilize it in a closed system. Drilling a mile please we drill two miles under a mile ocean off shore.

Oil is not a long term answer it is a short term fix to get us through the industrial age than worn out its welcome.

I agree, oil is not a long term answer. What I don't agree with are the current alternatives and their costs. We should let technology decide which is cheaper and effective, not government subsidies, including oil subsidies! If the whole planet said, no more burning fossil fuels, great! Not gonna happen. China is still building coal fired power plants for it's 1.4 billion people!

So why are you pushing a steam turbine? To produce electricity? Laws of physics say using electricity to reduce water to H and O2 and then using that to drive a mechanical device (turbine) will result in friction losses making it non-effective. How do you burn the hydrogen and oxygen? 

And I did not say drilling a mile, it would be tens of miles. Yellowstone Park with it's hot springs has magma 3-10 miles deep.

I'm all for non-poluting alternatives, who wouldn't be. But not at the expense of our enconomy and certainly not if other countries like China say; go ahead and we'll catch up to you, say, 10 years from now. Which is what's happening now.  

"How do you burn the hydrogen and oxygen?:"

Put a spark in it.

Everything without oxygen will oxidize aka burn.

It's how oxygen reacts to all elements but the Nobel gases. 

You can't burn helium. 

This what hydrogen oxygen and a spark does.

No this is not how physics work with water.

Water is an unnatural element. It floats as it freezes most any other element becomes more dense. This is needed or it would kill all non hibernating species as it froze it would sink to the bottom . filling an entire lake within a few days with just ice. 

Secondly water isn't a strong bonded element. The two gases hydrogen and oxygen combine in a lose combination and most other stronger bonds will rob the oxygen from the hydrogen molecule. Hence a small charge sepersted the combustible elements. 

Then steam high pressure steam is about as dangerous as any element it can cut steel. The mass to energy equation shows that this formula amplifies the potential energy water has. 

Problem is freezing water in its purest form freezes mire quickly the water with small amount of minerals.

Hence hot water will freeze before cold.
