how much power would be need to power a laser for Gold mining and Geothermal energy, to quarrying stone and building tunnels and how would you get the power source in situ????

I do not know how much power would be required, but the company seems to think they can get it into the ground.

We deliver multi-kW laser power over multi-mile distances.

In the past 15 years, high power fiber laser costs have dropped by 100X+ with modular, solid state construction for rugged field transportation. However, long distance transmission of high power lasers was believed to be impossible due to physics limitations known as Stimulated Brillouin Scattering (SBS) and other nonlinear effects.

Foro Energy’s proprietary technology overcomes these and other limitations to allow “world first” transmission of:

High power, by overcoming SBS
Over long distances, by overcoming SBS
With low loss, through a proprietary fiber optic specification
In downhole environments, through a proprietary cabling package

It looks like from the website that the first customer will be energy. That would make sense as the tight gas and oil requires many wells with multiple horizontal legs. There is a need for speed.

However, the Colorado school of mines is interested also. So, I suspect that there is a mining application.

I think we are talking a few years hence before we can invest ??

I think we are talking forever before we can invest. The two venture capital companies that are invested are not public. ARPA-E which is also invested is a government agency.

I suppose you could invest in Cheveron, ConocoPhillips, GE and NRG, but that would probably be like buying seawater for the gold.

I brought it up because in ground rock cutting sped up by a factor of four or more would have MACRO impacts. The spread of Fracking and recovering tight gas and oil could become very wide spread, depressing the price of oil
