Doug Vining Solar towers in the desert

Here's an example of harvesting the Sun's heat on a massive scale. These solar towers could be used for more than just driving steam turbines, as suggested in this MindBullet scenario.

Doug Vining Hydrogen from seawater

Sometimes it just takes a different approach to achieve a breakthrough - lateral innovation if you like.

Producing hydrogen from seawater using electrolysis is not new at all, but a fairly costly exercise that had no economic benefit - until now. Finding ways to capture CO2 on a viable scale, scientists have also discovered a useful by-product of the process - hydrogen.

I'm not sure that hydrogen should be described as "carbon-negative" but this process certainly seems to be, with other environmental benefits too. I wonder if it can become viable outside the laboratory?

Doug Vining Natural hydrogen

As we've mentioned before, hydrogen is not found in abundance in nature, and has to be manufactured, usually by splitting water with electrolysis, which can be done with excess solar power, but is not very efficient.
But what if you could use nature to do the job? Earlier this year, scientists produced a nano-particle consisting of an enzyme modified by a virus, which produces hydrogen from water naturally, rather like fermenting beer. Could this be the catalyst to launch the hydrogen economy?
