Soon Europe will need to expend more energy to heat during winters. Currently this is done with coal & Russian Gas (& French nukes)

Dacian has a better way that is actually cheaper than burning gas. Solar power used to directly heat a big thermal mass.

He moves generated electricity into big resistors within the concrete block & there is a controller that turn on / off those resistors. Concrete heats up by day & radiates heat at night.

Another cheap way is to heat a barrel of water using the resistance of wires running into that barrel.

http://electrodacus.com/ He also offers some great, cheap solar <-> lithium battery controllers.

Sweet, huh?

PS. I'm amazed he has received only 58,000 CAD. This is one seriously underfunded genius dude. Any VCs out there reading this should be beating down his door.

Here in Hungary I often see a sign saying that this beer stand or hot dog stand was funded by the EU & received about 60,000 euros. Somehow Europe does not have priorities straight or nobody in Europe have located Dacian (from Romania.. EU country) to give him more money than the average Hungarian hot dog stand receives.

How is this different to a normal storage heater? Most homes in the UK have them. They turn on when energy is ceap, the electricity heats concrete, the heat is radiated out.

So, he invented something that uas been commercially available for decades?

Good to hear the UK is already doing this.

He made a controller that allows solar panels to directly heat the concrete. I'm not sure if he invented anything. He made a controller, open sourced it, and produced & sold them near cost.

We will see. I trust you noted on the map that the whole of Europe is also reaching higher temperatures than before. We do not know if a slowing Gulf stream will offset the rising temperatures due to global warming, or not. A big reason for uncertainty is that we don't have any long term records of measurements of how much energy is actually transferred by the stream - good measurements only go back less than 20 years or so which is not really enough.

Yup, there is a chance we don't have do do anything. Then again there is a chance we are completely effed.
Would you please help that project by writing a one-page human readable description of what it does?

eg. I'm a non-technical home owner. What do I need to do to save energy in the long term? How much will I spend now, how much will I start saving?
