Why not make them build a tesla coil.

They are great fun to play with, and they
do not require alot of components.

I think it is very simple.

1) Make them coowners.
Part of the salary should be in company shares.

It is important that it is not in stock options.

2) Give them time to work on there own ideas.
20% like Google is fine.

This gives them both the encouragement and the
opportunity to invent for the company.

Considering that it is a economics calls.

You should suggest the teacher should drop the plan and instead set up a class note market where students can sell there class notes.

That would encourage students to write good notes
to get a high price, and good student could buy several good notes, study them and then write a extra good note to sell.

On my site http://crowdnews.eu/ 100% of the sign ups
is by openid.
But thats becouse it is the only option.

If openid is the only options for login
it does simplify the database structure for your site. But the code become more complex.

Also there are some bugs in the openid 2.0 specs. which makes it unsafe and costly.

Also I feel that openid is missing support for online shopping.

I have often felt that the should be easier way to supply all the info they ask, when you buy something online. Also postal address is usely formatted different depending of the region you live in. It would be nice if openid just had a field called postal_address which containd it in a correct user supplied format.

If the openid consortium could make openid 3.0
which made online shopping easier and maybe included a technology like http://ripple.sourceforge.net/
without the bugs in 2.0 then I think it would have a good purpose.

How does I think it works ?
And how do you thinks it works ??

Yes, you can still commit crimes and fraud, but you don't have to, in the present money system
some people is forced to commit crimes and fraud to eat and have a place to sleep.

We are all part of a local tribe we call friends and family and local peer pressure is all that is needed.

Well, you shouldn't analyze the two features in isolation.

That the is no credit limit means that crimes dosn't pay. It better to use the credit than risk beening cut in a crime.

The time, public record and peer presure will help limit the inflation.

With abstract value measure like $ the value can fluctuate. When you use a concrete standard like time, there is no room for fluctuation. 1 minute is 1 minute for everyone.

Also that there is a public record means
that there is a peer presure, so you might hear for it if your credit is very high.

I totally agree, but I think that the best way to do this is build the balance into the economic system by making a time based community credit system.

I made video about it to googles 10^100 project.
