Getting closer to fusion power

Will be nice to have unlimited power.
“After a long, seven-year development, an experimental fusion reactor in the UK has been successfully powered on for the time, achieving 'first plasma': confirmation that all its components can work together to heat hydrogen gas into the plasma phase of matter.
This transition – achieved last week by a machine called MAST Upgrade in Culham, Oxfordshire – is the fundamental ingredient of a working nuclear fusion reactor, a dream scientists have been trying to realise for decades.
In nuclear fusion, the nuclei of two or more lighter elements fuse into a heavier nucleus, and release energy. This phenomenon is what goes on in the heart of the Sun, and if we can recreate and maintain the same reactions on Earth at sufficient scale, we stand to reap the rewards of clean, virtually limitless, low-carbon energy.
Not that we're there quite yet, but the successful completion and first test run of MAST Upgrade is a significant milestone in the journey. The original MAST (Mega Amp Spherical Tokamak) facility ran from 1999 to 2013, and its successor has been in the works ever since, so it's an important proof of concept.”

It really, truly is our only long-term hope for sustainable energy with minimal downsides.
It's still been a long, slow gestation.
We'll see.

Yeah, I will believe it when I see it!

An itty-bitty sun is exactly what's needed.

as we used to say of one company I worked for a long time ago:Bringing you yesterday's technology tomorrow
Actually, I do remain optimistic re: controlled and sustainable fusion that "makes" more energy than it uses. But, so far, no go.
The uncontrolled kind works great, but it's kind of hard to capture the energy that's released.

Yup: E = m*c^2 (where m is the atomic mass deficit -- i.e., conversion of mass to energy when two hydrogen nuclei are fused to yield one helium nucleus)
Yes that delta m is small (per fused nucleus), but c^2 is really big, and thus, so is E.

No wonder I've been seeing "Chain Reaction" on Showtime a lot lately....So, are you willing to put forth a little effort or are you happy sitting in your skeptical poo pile?

I am skipping the whole electric vehicle thing and waiting for a fusion powered vehicle.

For a long time we have been able to achieve fusion reactions. The real problem is that it takes enormous pressure and temperature to start. Fusion bombs (the "H" bomb) uses fission reactions to trigger fusion. The energy gain achieved in fusion reactors has been less than 1. In other words, it takes more energy to achieve fusion compared to what we get out of it. The challenge over the years to achieve reaction gain greater than 1 of the usable energy. Usable, meaning a power output that does not include energy losses due to heat.
