When we can get to temperatures of about 1 billion degrees C, thats when we can get a proton-Boron11 reaction to take place. Totally clean nuclear power - Cool! (Have look at 'focus fusion') Hydrogen, deuterium and tritium? Doesn't this leave a neutron behind? Not sure. Fab article! Keep up the good work! Love the article, these are very interesting times.

Fab article!

We are talking from a temperature aspect, scientists have reproduced temperatures comparable with the spectral observations of the remnants of a supernova. This laser should also have some nice fusion applications, but there is no confusion about the differentiation between fusion and supernovae. I hope that clears things up a bit. Cheers, Ian :) alokmohan:

So skip the pressure and just go for the heat. Can't fake the gravity of the sun so lets do a work-around. Compacting fuel (hydrogen?) could be done using sound, magnetic pulses and if you have the heat, then boom...fusion. Or...hopefully not ...um...an actual "boom".

Heat isn't everything, otherwise fusion would have been established a long time before. We are missing the obvious component - gravity. And that pressure is no culprit to achieve.

All the writers on UT do this because we enjoy it, plus we all think that reaching out to readers in this informal manner is actually better than many of the mainstream media sources. Fraser gives us a lot of freedom to write on topics of our choosing and I think his model is going from strength to strength. I do admit though to occasional silly typos, but that is usually down to my haste to bring breaking news to UT. I think it's great to have feedback from our readers where the readers actually have a strong influence over the accuracy of our writing and choice of topic (feel free to send messages with suggested stories we may have missed). But Astrofiend is right, if you see an error, don't flame the writer, just send a polite memo that something may not be quite right. We all have a strong background in space writing, research and public outreach, any errors that may crop up are purely accidental and not a lack of knowledge.

One time less is zero. Subtraction is not multiplicative, it is divisive. Twenty times less enters (rather far) into negative numbers. Sheesh, science writers.
