Technologies coming up soon

Here’s a diagram I found showing the technologies we should expect in the near future(click the image for fullsize):

12 predictions for 2020

Not all of them seem to be realistic, but visit this page on popsci.com and you’ll found out.

Speculative Future History

You guys should read some things on this site. Don’t believe from the start everything that’s written there, remember: it’s only speculative. But the informations about the far future of our universe have a scientific meaning, so they are interesting.

Powering an LED- The nuclear way

So uhm, are you still using batteries to power your things? Common, they’re over 200 years old, it’s too mainstream!

Why not build a nuclear reactor at home instead? Did I catch your eye?

Heh, but seriously now, this article about making such a “reactor” at home caught my eye and amazed me by its simplicity. You should at least check it out

It uses some kind of  tritium vials that it seems are safe to handle, they emit weak beta radiation that doesn’t pass the glass. Although somebody should test these out with a Geiger counter .

DIY CD Solar Concentrator -attempt

Well, I thought of building a solar concentrator out of cds, but it ended up being just a … “reflector”.

It could work by having something painted in black and placed in the center of this thing, but I’ll try to build a concentrator some time.

Here are the pictures:

Actually, just before sunset, a couple of the cds( I think about 3-4, but they are 12 !) reflected the light into one spot: it was super bright. Now I know that if I build this correctly, I can have a powerful concentrator that can heat things so much they can catch fire !
