I've recently ready Kim Stanley Robinson's Ministry for the Future. It starts with a huge mass casualty heat event in India. I hope you get prepared in time. It's worth remembering that the risks to human health as a function of temperature is more severe at high temps compared to low temps. A few extra degrees in the 40C range is much more dangerous as a result. We can build buildings to have very load thermal loads through air tightness and insulation. Passive house reduces them to 10w/m2. We can cover our windows to reduce solar gain with mechanical shading. Balanced mechanical ventilation can use heat exchangers to recover air-conditioning. Multi family AC systems are better. However, PV electricity can be cheaper in the middle of the day, so it's necessarily worth running these systems at night despite better COPs. Variable electricity pricing is essential for a renewable energy transition. Ice storage has an issue that ice is a fairly good insulator. In Singapore, they're using large ice slurry tanks, where small ice crystals get suspended in a solution, to get both energy density and power output from the storage system.
Ice storage is sorted you can buy small units to large district size units . no one is making ONE Block its more like coil spring inside another coil spring so physical distance refrigerant and ice limit is very small .
@@s2tenglish Sure, but the heat exchangers do add to the cost and there is a limit on the charge rate. The large district cooling deployments, the additional performance of the slurry is worth the extra moving parts. The surface to volume ratios of thermal storage, the additional performance from more complex mechanical design, along with higher performance heat pumps (such as low GWP CO2) really do make larger systems much better. This is a really important topic, and I'm glad you're covering it. The other future trend is to avoid using refrigerant as distribution through the building, so hydronic convectors are the future.
hi love Future Friday. live near Melbourne Australia and to be honest global warming is not really an issue here. How ever I realise global warming is real. Over recent years they have built thousands of wind turbines covering huge areas of land. However with the amount of raw materials required I wonder is this really green, carbon neutral. I am wondering if we could better prepare the human race for the heat to come rather than try to control the climate which will cost trillions of dollars. The record heat of 2023 could possibly be natural. The under water volcano that erupted in 2022 near Tonga spewed millions of tons of water vapour into the upper atmosphere. For me go nuclear. They can come build it right in my back yard. I don't mind
there is only one issue with nuclear & its PRICE only on paper its have low price per unit but every plant that is here and REAL only causes bankruptcy and inflation .Price is locked so on paper its gg but bankruptcy means goverment has to bail it out and we are not in 1960s anymore solar and wind is much much CHEAPER that is why its gorwing U just see wind so it must be bad nuclear is out of Sight out of mind.anything that emits neutron is impossible to be cheap . for your knowledge seek what is the price of shielding californium and then remember anythign that stops NUTRON becomes radioactive eg normal water into radioactive water .
Love the episode, so much cool information!
17:30 I'm not sure if people realize this but... this is big.
Thanks for noticing
very impressive the cooling paint is important
It really is!

Instead of ice-batteries, for large apartments, can they not use underground air source?
underground air source? capacity is very very little and ground is not conductive . geothermal is great for heating not for cooling
sometimes I wonder why no one is talking about the climate change in India
every one is literally from IIT to parliament its just not sexy so coverage is very little
window awnings !
PV panels can be window awnings
humm U just watch Technology Connections ?
@@s2tenglish yes, for a long time
