Cooling the house for free
 |
| cold for free |
We need a metal to form a neutron helix. The element you can be bought for under three UK pounds, and then slowly around a large send the cell and or like an old dustbin.
We then invest in a small solar powered pumps. And we compress the natural warm summer air. And we link the pump to a metal helix. Which we are placed on the little stand in the garden wall or hanging out of a flat window.
As a compressor gas it gets mad hot! It is why the pump may he have heat friends instilled. We have some regular forming fittings, and pass the compressed air into the metal helix.
It then loses the heat to the natural air - Whitney U space is to hold it away from the flat wall. Or we have stand the helix on a little metal stand. Own the bulk of the heat is transferred to the air.
No temperature of the gas rises according to the temperature in degrees Kelvin. Which use degrees Celsius plus 273. So the regular error is between 40 and 50° C. And as we double the temperature of the gas, thermodynamic magic happens!
1 (T+273)xP=(Tx273)/2 x 2P
We then vent the gas or what is technically known as of injury fossil: a nozzle which diverges. So the exit gas so at -150° C. Which he is one hell of a cold blast!
So we obviously had ambient air, to get 10° C. And we've got almost free air conditioning! So are talking area plant for under 13 UK pounds

So we are talking about 15 UK pounds, plus the plumbing supplies. So under 40 UK pounds.
And as the sun shines the finish out water cold air for nearly free. Ideal for her large public area. We may be new to turn down the pump for home use. All first year undergraduate university thermodynamics.
And all the heat is thrown out to the air slightly removed, and then we had our cold air. So we have a efficiency losses, and nature continues disterved.
My friend is after weld up a system! As he likes his welding. So next week I will have some practical results to give you! Seriously it is first year university thermodynamics.

Weather today in Manchester nothing special
 |
| Nice but not hot |
,37° C max, 17° C min. Sunny and a gentle breeze. I only used to jogging down the road in Hong Kong, at 40° C. And that is as far as 2022 will get! So we had two decent days in the year. Usually a summer is three days!
A record breaking 42° C. Maybe in India! An average summer day for them.
Tomorrow 17° C. Get your thermals ready for winter! Ever year, 3 days of summer.
Free air conditioning

This is from the first year engineering thermodynamic so in the 1980s. So familiar to every scientist since the 19th century! As industrial revolution kicked off.
We have a small 20 W solar panel. We could use of mains as our power demand is so small. The pump below is over kill.
We pressurise regular warm air, let's say at 40° C. The absolute temperature is degrees Celsius first 273 - to give us absolute temperature.
Now basic flow and dynamics teachers us,
1 E=P+T+V so energy in is directly linked to a void the temperature times the pressure. Now use a little solar driven pump to double the air pressure. Which is a trivial amount of energy!
That is anyone be who is part of a bicycle tyre knows pressurise there is hot air.
So at 81 metre of air air at 40° C, 313 degrees Kelvin. So we pass it through an aluminium helix 10 feet off the ground. And all the extra heat is thrown away to the air.
At ground level by taking the gas to where we want cooling, in the lounge or in an area communal area. We then vent the gas through a Venturi nozzle: a novel which splays open!
We have called the compressed gas down and to our 40° C. And every so tracked the 27380 cures degrees Celsius. So we get -243° C. This is the ultimate polar blast so he obviously makes it we've had twice as much regular air. Which is still giving us that -120° C. AK it may be want more regular air!
And all the pumping is provided for free virus solar panel. Which cost around 20 UK pounds. All run for ever! Totally mains free. And we get a follow blast at -70° C.
Which use of a bit cold - but the cold will dissipate in the air at the centre or house. Producing an ice cold blast. Without any water particles! So three air conditioning. Couldn't be simpler!
The climate change brigade are still on about nuclear power. Which causes plants using loads and loads of reinforced concrete - produced via A fossil fuel burn on limestone.
Making nuclear power the fourth largest manmade source of carbon dioxide on earth. So not carbon zero!
And he in the winter we lose their heat of the compressed air, directed the house air! Via another alley immune helix.

This is just summer
 |
| just nice |
The BBC was talking about 40° C. Indians there must be laughing at us. I have just looked on latest BBC weather for northwest, and Monday and Tuesday will be 27° C. And that is as hard as this year will get!
Farmers can set up a little solar driven vacuum pump, to some water vapour from a river, and then to use a cooling mist over the high ground. But really is there a need? 27° C is just nice. 35° C is hot.
And all throughout Europe for medicine freely set up a mistet to cool and moisten the air. A red weather warming? I don't think so. 27° C is just pleasant.
Be sure you have a thermal for winter, the longer term weather forecast is from -5° C. But let's face it, they cannot get tomorrow's weather correct. It really is not a red weather warning situation.
But there is a static trace of carbon dioxide in the air. Just two parts per million around the temperate earth. To do plants on land and sea sucking in carbon dioxide, to form plant biomass. A static trace of carbon dioxide is left!
Man's industry revolution is boosted life on earth. But not affected the weather.
