Sustainable Cooling That Doesn’t Warm the Planet | Rachel Kyte | TED Countdown
“The way we cool things down is heating the planet even more,” says sustainable development expert Rachel Kyte — and the solutions go well beyond just fixing air-conditioning. She identifies four major areas with transformative solutions — from roofs painted with bright white paint to solar control glass to more efficient cold chains for vaccines…

There has been solar powered refrigerator units for decades now. The same technology that was used in early gas (not gasoline) refrigeration. The absorption cycle using ammonia works, is lo-tech and CFC free. This tech is out there and this lecture doesn’t deserve to be a Ted video.

The carbon footprint is mainly Agriculture. And I don’t mean cows, I mean all of it. Fossil fuel energy could be eliminated at the click of COMMENT on this post and we’d still be rapidly approaching 1.5C, nothing in this presentation is helpful to reducing the levels of carbon in the atmosphere. Absolutely nothing. This is corporate propaganda designed to sell more of the problem at a premium rate.

@Diet Pizza I dont get your point. This is not only about technology that doesn’t exist yet. Even if we were only talking about that, we can get there, when the engineers of such companies focus on getting to a more efficient tech. It’s not crazy stuff, we have been making things more efficient all the time.

@TheMagicJIZZ It gets upto 45°C in India
JustSen
March 11, 2022 at 7:16 am
@Rahul Chanana And the lowest? According to Google it’s been lowest around 15°C. If you live in India let me ask you this, do you walk around in t-shirt and shorts in those temperatures? 15°C is when I am comfortable with t-shirts and shorts while anything above 25°C is hot. Anything below 0°C is chilly and under -10°C gets cold.
I work in building maintenance which includes ventilation/heating and cooling in a nordic country and I’ve met people from “hot” countries like India that have moved here for work and they’re complaining about a cold working environment in an office even when it’s been 25°C indoors and I’m sweating like crazy in t-shirt while they’ve been wearing long sleeves and sometimes even jackets.
So I’ve come under the assumption that human body adjusts over time to the climate they live in. And since from -25°C to +30°C is nearly a 50°C change in temperatures 30°C is pretty damn hot from our point of view.
Rahul Chanana
March 11, 2022 at 7:39 am
@JustSen The temp range in Amritsar, India where I live is from 2°C in winters to 45°C in summers, still we don’t use any kind of active cooling/heating, only passive insulation. Get your facts straight.

Sustainable cooling by more efficient cooling….doing ANY sort of work produces heat as ‘waste’ energy. Does she not understand the second law of thermodynamics?
She’s just stating a bunch of ideals without how to actually do anything.
Then she goes off about vaccine distribution. What is wrong with this woman?

The French company “Leviathan Dynamics” is developping a cooling system that is using water instead of HFC as a refrigerant, it is also using 30% less energy than traditional air cooling systems.

2:15 That’s the problem, the people who are responsible for causing most of the heating, as well as the people in charge of making policies are always rich people who have heaters and air-conditions in their homes, cars, offices, clothes, etc. so they never have to feel the effects of the cold or heat they are causing or responsible for ameliorating. Maybe if they could feel it, they could relate the plight of everybody else and be more amenable to dealing with it. 😒

@kalidesu Poor people can’t afford to waste heating or cooling, most can’t afford it at all. When people can afford to waste resources, they don’t put in nearly as much effort in conserving those resources.

It’s not coal , it’s a cold chain. A way of transportation of goods where the items in cargo need to be maintained below a certain temperature.

It strikes me as rather amusing that suddenly the air conditioner has become the villain when no one complained about the heater. I have three air conditioners that never get switched on, and at the same time, in winter I shivver because I don’t have a heater.

This is largely foolishness. Simply superinsulating all new housing, reinsulating older housing, insulated shutters, and instituting inexpensive energy recovery ventilators and whole house fans will cut cooling AND heating use and costs by 80-90%.
Most solutions are far lower tech than you think. Simply putting awnings over windows will accomplish the improvements on energy use you discuss.

NATO said 16,000 volunteers to fight Russia, sorry? To defend Ukraine! ? And the Russian state said: “Do we allow 16,000 volunteers to enter the battle?” same Number!!! Agents of both sides are talking about biological and semi-nuclear attacks, and unfortunately, in 2 to 3 weeks we’ll see some of those pictures mentioning a fireball.

If all you have is a simple fan and water, just put a large wet towel on your shoulders or back and let it dry. within minutes it will cool your body very nicely for low cost. works even better when combined with a fan.
