Congrats to all Ben's team and for innovate without age borders!

Very nice talk!

Hi Ben... its my pleasure to see your presentation its my dream as well, Its really great work, I'm having an interest of getting every thing at home from natural resources zero in zero out self-sufficient houses moreover a productive houses, organic foods, healthy ,I'm a one person who believe on this dream I know it is huge and I should decompose it into small projects, but I don't know how to get people convinced with the whole project , to give a budget to realize these things is a proposal sufficient? Is it the media? etc...Thanks in advance..

I am watching this video while it is 8 years old. Why are we not seeing these buildings anywhere? It makes much better sense!

BRAVO!!!!!

This is an old fix to a constant problem. We used to have these water cooling units on the top of our buildings. Electricity was necessary, when the wind didn't blow, and it was also necessary for the blower. I like the design of a hole in the center of the building to circulate air.

Add solar powered blowers 2 not need as much electricity. And you could even add batteries that the solar panels are charging to use when the sun is not strong.

Indeed, a solar powered cooling tower would be great

I didn't meet anybody who would complain about air conditioning during hot summer. The ventilation systems have silencers in canals, the air flow velocity can be set up. Heat pumps are quite common. But what he didn't mention is the borderlines for project that determine building height, size, type, surroundings, local law regulations etc - it all has impact on the shape of the building.

Can this special roof be used also as a part of Wind power plants? Does it help to increase the harvest of energy?

need this for my room. should downscale it.

Dig a tunnel below ground where the temps are cooler. In this underground tunnel place a coil of pipe to run water through and into a heat exchanger system. it's called geothermal.

We need to start living under ground or mimicking underground building. The pyramids and other old buildings were so thick it is like being underground. Underground is a good temperature for us. Catacombs are cool in temp. They knew back then

Problem is, it's more expensive to do so as well as more dangerous. Look at mining. A better, safer, cheaper system of building down will have to be done. Look at Elons tunnels project for his hypertrain.

I think for implementation for actual condition is not simple, I understanding the concept, the cooling effect is due to the latent heat that needed to change the liquid phase to steam phase of water. and the heat is taken from the air that passed trough the water. after the air trough the spray water the air become colder then inject to the room, with the same time the air became humid (the humidity) increase and this condition will limit to change the process of phase changes (from water to steam) and make the cooling effect will also stop. For big capacity of cooling load i think this concept can not be implemented for instance cooling load 250 Ton refrigeration up, cause the cooling effect that produced by this concept will not enough.Cooling effect is produced by latent heat of water.

Where did he spend the million Euros?

I watched the whole video, but I'm not sure I caught an explanation of how termites keep their hills (or whatever their structures are called) at constant temperature. I would really like to know.

It seems their orientation (long wide sides E-W, narrow sides N-S) helps create difference in temperatures. Basically until midday sun will heat up one side, whilst the other will remain in shade and relatively cooler. This will cause air convection inside the mound due to difference of air density between sides and interior vs exterior. Sun is in fact powering their air conditioning and in more shaded/forested environment it's more difficult to control inside temperature.

The Austrian movie archive was build from wood and have a stable temperature which is necessary. Erwin Thoma researched with experts from BMW and look how ants build their nests

This man should talk with Erwin Thoma i think they could create something beautiful together.

Simple question that he doesn't answer: What happens to all of that "moist water vapour" that comes from the water cascade? It cools the air in the summer and preheats it in the winter, (that's understood). However, where does all of that water vapour go to? Are you using it the "humidify" the building? It could get very uncomfortable to have a relative humidity about 75 percent. No fans to help circulate that air? Water vapour is lighter than air, so it would easily accumulate in the upper floors, (very muggy, even if the temperature is low). Unless you have an arid (dry) climate, you should also be looking at "dehumidification"; but, it's not mentioned in this presentation. Those termite mounds are usually found in arid climates, (not in the Netherlands).

Air conditioners used sealed tubes to control the moisture and humidity, in his design it would need a sealed chamber of sort.

Wow, termites are natural climate control architects and engineers? What incredible luck! Many of our buildings ALREADY have climate control colonies incorporated within their structures! Hooray!🙆😏

The Egyptians created wind catchers still used in Iran today and hundreds of years old

I don't think this could be applied in hot humid climate.

Too much lead in. Description rushed, diagrams not labeled. Would have liked to really understand what he was describing. I think the only people that could get anything out of this talk would be those that already ibderstand all the systems he describes.

Architects too are rational and logical, engineers are taught students, architects are educated ones, ya only if they take their job seriously.

Delft is Vermeer's birthplace.

Funny.. This technique was actually practically and is still being used in middle east since ancient times. You can google for wind catchers.

No person who lives in Phoenix Arizona does not complain about air conditioning. We need artificial air conditioning here during the summer. Why? Well even at night it doesn't cool down. It holds the heat. There is no cool air breeze here. For inventers like this guy. You should live a year or two in Arizona and think about natural air conditioning here. But nothing about AC bugs me other than the energy bill here in Phoenix.

The first idea 💡 was okay the second was not so

Disappointing talk. He basically described evaporative cooling with a solar chimney for air flow. I was looking forward to something new. Also notice how he hides his one hand when talks about receiving the funding, I don't think he believes he spent the money well.

Yes but incorporating those design principles resulted in a 40-60% reduction in energy consumption and don't forget the power generation produced by the building via wind and solar PV accounts for all or nearly all the remaining energy needs of the building. Obviously is a great step in the right direction. What we need now is for close minded and stubborn architects to start promoting this to their clients.

I am an HVAC contractor and every now and again when one of my customers is faced with a difficult problem with their HVAC plant I will sometimes joke when offering them a solution and say “well I figured out your problem...you need to relocate your building away from your air conditioner.” However in this case you would have to literally do so if you were done dealing with a system like this. 😃

Nothing impossible until ignorance says so.

The polite chuckles are annoying.
