LIGHTPAPER

A local Ceour d’Alene company (right next to Spokane) has created a lighting technology where they can print a paper, put electricity to it and it lights up.

Essentially, it is a printed LED – the world’s thinnest LED that is and it is quite revolutionary because it opens up a lot of possibilities.

Silent Refrigeration

A refrigerator uses a traditional heat pump. A compressor is powered usually by electricity and that circulates a “refrigerant” like freon or some synthetic version through some tubes that go through heat exchangers – the bottom line is that is pulls the heat out of the fridge to make it cold.

An AC is just another variation of this as is all other heat pump technologies such as heat pump hot water heaters. Some give you cold while expelling the heat and some give you heat while expelling the cold.

Heat pumps are a really great technology and are very reliable and have made our lives much easier. There are a few drawbacks such as the noise and occasional maintenance due to moving parts.

Phononic is a company, which has eliminated these problems by building a completely silent and solid state refrigerator using hundred year old Peltier junctions…they’re semiconductors basically that get hot on one side and cold on the other.

Peltier’s definitely work but their drawback is that they are very inefficient…it takes a lot of watt hours to produce any substantial heating or cooling, but Phononic has scaled them up and have made them more efficient than ever. Normally, they’re under 10% efficient, but now they’re over 30%!

Even at 30%, they can’t compete with heat pumps in terms of Coefficient of Performance (COP), but being that they are much smaller than normal compressor heat pumps and they’re silent, they do have their place.

While this advancement in Peltier technology isn’t going to get anyone off the grid, it is a very welcome improvement as a three times increase in efficiency in anything doesn’t happen every day.

To put that into perspective – the automobile engine was commonly under 20% efficient and the newest cars on the road today are lucky to achieve 30% efficiency – and that is over many, many decades of automotive advancements.

Tesla 2.0 is back!

I received literally hundreds of emails about the Eric Dollard interview video on YouTube going private. Before that happened, there were literally thousands of views. Eric Dollard exposed a few people in that interview and they retaliated so the producers of that video, Union Features, made it private but re-uploaded an edited version here:

 

Even if you already saw the video, please play it for a moment and click the THUMBS UP button at the top right of the video to show Eric Dollard your support!  

DOWNLOAD THE UNCUT VERSION HERE: Quite a few people downloaded the original and they’re already uploading it to multiple places to preserve it. Click the following link, click the button that says Download This File, enter the captcha code and hit the button and it will download in a zip file. In the zip file is a high resolution mp4 of the entire uncut interview – there is no Copyright notice in the video but that doesn’t mean it isn’t copyrighted – check with Union Features if you have any questions: http://www.filedropper.com/tesla20mp4
