Two counter-rotating flywheels perhaps?

Or am I omitting something from consideration?

I think that would work nicely! :)

Another solution would be to mount the (single) flywheel and its associated motor/generator in a set of gimbals. That way the bike would be able to lean and turn and the gyro could just keep aligned in whatever direction it likes without any gyroscopic effect on the bike. I suppose you'd install the flywheel with its rotation axis nominally vertical and have some light springs and dampers to stop it drifting away from that orientation over an extended period of time - that would prevent the flexible cables between the bike frame and the gimbal-mounted flywheel unit from becoming twisted. There's some torque reaction when 'charging' or 'discharging' the flywheel (changing its rotational speed), but because it's rotating very fast and power is torque x rotational speed, the torque required for any reasonable power level is very low.

Article about the solar boom and bust in Japan:

http://asia.nikkei.com/Business/Trends/ ... r-new-dawn
Some 80% of Japan's "megasolar" projects, so called because their scale is measured in megawatts, do not produce a single watt of power (1 megawatt equals 1,000kW). Poor planning is to blame for many of these failed starts.

Poor planning?

Never heard it called that before.

Stark, raving idiocy perhaps.

Actually they run the turbines at full power, but use the excess to pump some of the water back up to use later. It's better than trying to slow down the turbines in large dams. Been done since like forever.

Adding solar panels to run the pumps (which are already in place) is a no brainer for storing solar power. especially in desert areas where huge dams already exist, with pumps already in place.

There's a reason they won't do it. And it is money.
It’s always surprising to find that still in this modern age profit is the prime mover. Unless you the government, but even then money is the mover.


Unless you’re some kind of idiotic socialist communist fuck hole Third World country, most people, all sane people really, don’t run things to lose money
